Turbo Rebuild Limited Td5

[rangieman]

Seeing as my other post got buried in another section i thought i should start a thread on this to help others in the future .

Sorry no pic`s.

Now this mob do a Uprated Hybrid Turbo Cartridge for the Td5. The cost at the time incl postage was about $430.00 AUD

Uprated Hybrid Billet Turbo CHRA Core 452239- Land Rover Defender Discovery TD5 Turbocharger Cartridge (https://www.turborebuild.co.uk/webshop/prod_5700273-Uprated-Hybrid-Billet-Turbo-CHRA-Core-452239-Land-Rover-Defender-Discovery-TD5-Turbocharger-Cartridge.html)

Now i took the jump and ordered 2 one for my self and one for Wardy.
Now the job consist`s of removing your Turbo from the manifold and dismantling the core from the dump pipe and intake side .

It is not a hard job in my opinion but you may have to customise a 10mm single hex flat ring spanner to get the bolts undone on the exhaust side of the core apart from that the rest is fairly easy if your handy at turning spanners .

The core comes supplied with copper washers for oil feed and a paper oil drain gasket and a syringe of oil.

I did buy new exhaust to turbo and turbo to manifold gaskets and the LR tin oil drain gasket from Roverlords as i did not like the supplied paper gasket .

The job can be quick or it can take a while for several reasons , All i will say is if your not confident do not attempt to do it as it can turn pear shape very quickly .

I cheated as a had a old Td5 turbo so i did it off the car at my own time and then it was just a matter of a straight swap .

I did mine then i did Wardys .Hopefully Wardy will chime in here .

Now the result is just bloody unreal in stock tune both my self and Wardy are now having second thoughts on a remap (Not Really[bigwhistle]).

Of idle torque has improved mid range has improved and top end has improved ,
Now mine is a manual and Wardys is a girly auto car [tonguewink]

We both have heavy campers mine dry is 950 kg and im guessing maybe another 300 loaded .

The improvement in towing performance is a big improvement aswell .
So it is a really good bang for buck mod with great seat of the pants dyno improvement`s[thumbsupbig]
It is stated to get the best from this Turbo a remap will help big time.

All of the above and then some with the (girlie) auto[emoji35]

I reckon I have 20-25% improvement in torque, the car is just totally different under load, it now seems to actually enjoy it.
One hill that had me back to 2nd with the trailer on (about 1300kg) was easily traversed in 3rd, only the last bit forcing the change down from 4th.

Off road was equally impressive. The extra pull was very definitely noticeable.

I was lucky having Chris there to do mine, it's a job for those with at least moderate skills. I COULD have done it, but it would have taken a hell of a lot longer and maybe I would have had the skinned knuckles instead of him [emoji23][emoji23].

Chris and I both had difficulty wiping the smiles from our faces last weekend [emoji3]

[Tins]

Curious about this. I did something similar to my 300:


Old.
126665


New.
126666

Admittedly, the old one had about 2 or 3mm play in the shaft, but the difference was astonishing. Biggest problem was the bloody circlip.

Very interested in updates. I'd like to do this to my TD5. It already has a chip.

Wardy, tell Chris to shut up about autos. We both know they're better.....:thumbsup:

Seems like a worthwhile upgrade.

Good feedback thanks, I have 2 of those sitting here , plus one assembled and waiting for my d2 to come back from loan when I finish rebuilding their girly r380 [bigsmile] mine already has remap , boost box , exhaust etc, so looking forward to this, I will be getting 2 manifolds and 2 turbine housings ceramic coated for the other 2 chra's , you'll be beside yourselves when you remap[biggrin]

I did watch this and believe me the vid makes it look a lot easier than it really is [wink11]
There are a few hurdles for new players .
1 . The Bolts that hold the core to the dump pipe should be replaced as they are on the hot side and tend to round easily .
2 . One should take photos of the standard turbo before dismantling so as to get the orientation correct.
3 . Also as i state get a tin LR oil dump pipe gasket as the paper gasket supplied is not as good as a tin one .

I've got a Td5 'towing' map on mine. I've only taken it for a short drive since fitting, but the boost comes on much smoother now. Before it was all or nothing.

Your original post in that other thread Chris piqued my interest as this seems an incredible bang for $

After hammering a manual 3.2 BT50 during the day for work and quite a few weekends away over the last twelve months ( prior to the Disco arriving) the Disco really does need more torque.

You could always tweak the waste gate Rick thats good for a couple of Nm.

Does yours feel stronger/ more torquey kelvo?

[kelvo]

Does yours feel stronger/ more torquey kelvo?
Not a massive difference using my arse dyno.

But the power delivery is smoother, and EGTs slightly lower. I'm running 18-19psi boost. The real test will be in a few weeks when I'll be towing the 1500Kg camper around the Pilbara.

On a standard tune the difference in power/torque would probably be felt.

The wife has driven it today and made no mention on it going any better, or worse. As far as she knows I just carried out an oil/filter change on it.

She noticed a big difference when I put the Td5 Inside map on, again without her knowing what I had done.

Thanks ,Yep , a big difference would be felt if the old turbo was worn as well , at least they seem to be more efficient at higher boost levels and as mentioned, every bit helps, biggest bang for buck is a decent remap, I'll be running 22 psi when car comes back on Friday and report back

[wardy1]

Well, here's the word from Wardies girlie Td5.
Just did a bowser to bowser run of 1502 km. This included suburban stuff , the run up to and back to WWB7 and a run to Geelong and back today.
Now I've enjoyed Eco around 10/100 in the past, but get this.......
8.2/100!
Now I've double and triple checked this as I didn't believe it myself. Filled at the same bowser, from the same side at similar temps and there it is. I'm absolutely stoked. More power and less fuel. Can't wait for the remap in a couple of weeks........ Catch me if you can[emoji23]

[wardy1]

Oh..... I was towing about 1300kg up and back toWWB7 as well

I have emailed them and asked what sort of numbers they require and discount etc.

by way of a straw poll, would anyone else be interested?

[Jason789]

Hello.

I saw this thread a while back and thought the improved turbo cartridge looks ok. My turbo then conveniently blew and I needed a replacement so I ordered and fitted this new you beaut turbo cartridge.
I have installed the cartridge. Power is up, but so are the egt's under hard accelleration(not good for when I'm towing, but not tested yet). I have a 2a intercooler, a plug in chip and straight through exhaust, which previously had given no problem with high egt's..
There is no overboost occuring and it is adjusted to maximum boost without hitting the safety.
Everything was cleaned from the oil that went everywher internally, intercooler etc

Does anyone have any theories about how to get the egt's back down??

Cheers,

Jason

[PhilipA]

Does anyone have any theories about how to get the egt's back down??

Take your foot off the accelerator a bit.

Mine would run up above 750C if I keep my foot in it, so I just back off a bit and hold at say 650C.
Regards Philip A

[Jason789]

Hello PhilipA,

Taking the foot off is the easy answer. That is what the alarm was installed for.

My question is more about what has caused the egt's to increase and how to get them back down through adjustment. As with the old turbo, I could put the foot to the floor and the alarm would rarely go off.

Kelvo stated that his egt's were slightly lower. What I want to know is why mine have risen.

Cheers,

Jason

[donh54]

My opinion, for what it's worth.... Most piggyback chips work by increasing the fuel, either in quantity or dwell time. The added boost from the new turbo has changed the parameters that chip was designed to work with, hence temps rising from extra fuel at certain throttle openings/ system loads.

[PhilipA]

My question is more about what has caused the egt's to increase

Well, we would all like to know that one.

Offtrack has indicated that in his opinion most tuners are pretty crude and just add fuel to the stock map, rather than adjusting timing etc and mentioned one tuner who in his opinion had it correct.
I cannot find this post now .
The max boost for the altered core is 22PSI, and I am touching that on occasion so there is not much room for increased boost to reduce EGTs, it would have to be by a sophisticated map, although I don't know if such a thing exists. I have no EGR, decat, coated exhaust manifold, performance muffler, serck intercooler etc so no scope for me to do any more, and I recall you have the same.

A performance intercooler helps quite a bit.

May be try and Unplug the piggy back chip and see what happens, you might find you don't need it anymore?
Maybe a proper ECU remap like TD5 inside might be better than a an on chip. Only trouble is Td5 inside doesn't appear to answer emails anywhere.?????? so don't know how to get in contact.

Yep x 2 unplug the chip .
Chips are for eating and i dont know what brand you have nor really care as they just fool the ecu and bang more fuel in and not where it is really needed[wink11].
A correct remap is the go say jose Td5 inside any dramas and he will modifie it to suit your needs and style[thumbsupbig]

The chip has been in for many years and proved absolutely reliable for extra power and, getting 1000km from a tank of diesel isn't bad either. You would be surprised at the extra power it provides.
I did sell it to someone else on the forum and then bought it back.
Don't can something that you've only read about and haven't used personally.
I also use the same type of chip on my motor bike which gives 95% of the extra power that a PC3 provides at 10% of the price(which can be set to add fuel for acceleration, set fuel ratios for idle and off power, and set to rev ranges too). All you need is an AFR guage to set it, no dyno time requiered and no rip off for a software change that these people charge exorbitant amounts of money to change for a few key strokes on a computer.
Technology has come a long way.(Load based technology)
The one tip that I did get from Turbo Rebuild Limited was to fuel the engine up rather than fueling it down to reduce the egt's. Removing the chip will fuel it down.
So I guess I'll keep looking for tips.

Cheers,

Jason

[donh54]

More fuel in = higher egts. Thats how diesels work. Burn more fuel, you get more heat. It's almost the polar opposite of a petrol engine, (leaning out the afr melts pistons - ask me how I know).

[rangieman]

The richer a diesel runs the hotter it will get and the more damage you will do to your motor .
A chip is a dummy form of tune , You need a tailored tune , Not a one tune suits all which a chip does .
So if you have a AFR guage and as you say you can adjust your chip as you said you can then id do so , If not it will all come down to your chip as you now have a more efficent turbo than standard and with a chip that is more than likely inacuately over fueling at the wrong time.
Im running the standard tune and dont have any issues with high or higher EGT`s [wink11]
Id try with it unplugged or a tailored tune apart from that i feel your chasing something that is not there[bigwhistle]

[kelvo]

Only really true if too much fuel is put in.

Upto a point adding fuel can reduce EGTs. The extra fuel spins the turbo harder, turbo produces more boost, more boost controls EGTs.

[Jason789]

So, I wasn't running high egt's. I install a turbo cartridge, get high egt's. There is no way to fix this except with a newly programmed ems or disconnect the chip??
I love good advice, and l'm still looking for it.
Cheers,
Jason

[kelvo]

What boost are you now getting with the new CHRA?

[donh54]

Only really true if too much fuel is put in.

Upto a point adding fuel can reduce EGTs. The extra fuel spins the turbo harder, turbo produces more boost, more boost controls EGTs.

Let me explain it a bit differently:

More fuel than the available air can combust cleanly, will result in higher egt. The new turbo is putting in more air, so theoretically, the egt should be dropping. But it isn't. Why? Because for some reason, the chip (or the original ecu) is feeding more fuel UNDER THAT CONDITION. (Wide Open Throttle - under load).

You say you can adjust the chip - I'd suggest you look at adjusting it for those conditions. By adjusting, I mean leaning it out at that point, until the egt comes back to a safe level, if it allows that sort of adjustment.

Thinking about it, as a piggyback or plugin chip, what inputs does it manage, and what does it leave to the original ecu to manage. The extra boost you're getting now may have triggered something that wasn't noticeable under less boost. Perhaps the ecu is extending the dwell time due to some signal it's getting.

EGTs drop with more fuel generally only when the engine is spinning up, or at low rpms because the turbo requires more energy(heat) to rev up. (That will only be readily noticeable if the probe is sited immediately AFTER the turbo, i.e on the exhaust side). Once the engine reaches WOT the turbo is spun up, and doesn't use up as much energy (read heat) to maintain boost.

It's probably best to sort this out pretty quickly, as the damage from excessive egt is cumulative.

[Jason789]

220 kpa is the highest that I've seen on the boost.
Jason

[PhilipA]

So 32PSI minus 14.7 = 17.3PSI.

I would think a tweak of the wastegate to 20PSI may help. Or to 240Kpa.
Sorry I think in PSI.

Regards Philip A

[Kaaaiju]

With an new turbo cartridge can one run about 21psi safely?

[clintooo]

I got a reply back overnight.

He could do pricing as follows:

5+ 240GBP which is around the $400 mark depending on what exchange you get.
10+ 230GBP around $380

those prices are delivered to Aust and with everyone just paying individually.


Not a massive cost saving on what Rangieman paid, but it is a bit off their list price. I'm guessing they are rather heavy and shipping is a little expensive.

What do I need to do to put a group buy up, do I need any permission?

Clint

[strangy]

......Only trouble is Td5 inside doesn't appear to answer emails anywhere.?????? so don't know how to get in contact.

Same. I can't get a response from Jose and have been trying for some months through PM and direct emails.
Unfortunately I will have to sort through someone else.
Having the tune, eventually, is one thing, having a response inside a suitable time frame if ever I have difficulty is another.

[Jason789]

Hello,

Well the unit now works perfectly now that I have had a little time to play with a few settings.

1) Wastegate opened(rod shortened) up three and a half turns. Was on max with the old turbo but it did have a broken vane on the exhaust side.

2) Upped the fuel output on the chip to maximum.

This allows me to have WOT for sustained periods going up a decent gradient without the EGT hitting the dreaded 703 Centigrade.
The new cartridge is a dream after a few minor adjustments.

Thankyou all for for your responses.

Cheers,

Jason

[Kaaaiju]

So is an plug and play chip worth the upgrade or just turn up the boost?

Thanks for highlighting this, mine's on it's way. I just hope it's worthwhile. My excuse is there is a smigin of play in the bearing and it is cheaper to go this way than pay to o/haul the turbo. Oh yeah, smigin is a technical term!

That would have been Alive Tuning, but I'm a bit biased as I've been speaking to Gary on and off for a few years, and discussed a lot of the new style mapping with him late last year.

Apparently BAS has also changed the way they do TD5 remaps recently - but that is here-say.

No idea with Td5Inside.

Love the data! Well documented.
That speed is miles per hour right?[emoji848][emoji3]

[OffTrack]

this now maxes out the AFM so working on that solution

I've have made a mod for the stock MAF that extends the range out to about 830 - 850kg/hr.

It should be reasonably accurate - not that it makes any difference really as the changes are made well above what the ECU uses to calculating fuelling.

The tuner pro XDF's I make have a patcher to apply/remove the mod.

[kelvo]

I'm back from my trip, 5500Km towing a 1500Kg camper trailer.

It was a lot easier towing with the new CHRA compared with the original turbo. The ability to hold my speed on hills without having to plant the accelerator and worry too much about EGTs was a big bonus.

This will be more specific to my ECU reMAP but holding the boost around 16Psi gave plenty of power without high EGTs (450-550*C pre-turbo), in my manual D2 this is about 2250rpm in 5th at 100kph so ideal (Yes I know you shouldn't tow in 5th).

Fuel economy was also very slightly better, a drop of 1ltr/100Km compared to a similar trip with the original turbo.

So I'd definitely recommend fitting the hybrid CHRA if you tow.

​Hello,

Just a further update on the cartridge install.

It whistles noticeably more than the original turbo. I can't ever recall really hearing the original turbo much at all.

The air box has had the you beaut turbofan fuel saver thing and other bits removed from inside the airbox as well as the muffler replaced with a straight through section of exhaust pipe.

Like I said, a bit more whistly(is that a word?) but not a real bother as there is no muffler anyway.

Cheers,

Jason

Is the whistle a familiar tune? does it get stuck in the head?[bigwhistle][biggrin]

[Mr whistle]

I am considering doing this turbo mod as my turbo has a fair amount of play, I just want to make sure it will work well with what I have done. I have just installed a serk intercooler, silicone hoses, de cat and have just got a remap from trs in SA. If I do will i need to install a boost box from alive tuning?

No you wont need a boost box , Fit the turbo and forget[wink11]

[singlecell]

Will definitely have to get one of these! Looks awesome for the money. Is it best to get a specific tune for this upgrade or will current tune already be doing the same thing?
In regards to boost, my boost gauge which reads from the inlet manifold says I peak at around 22psi, Am I correct in thinking the engine is meant to limp when passing over 21.5? I assume there is some issue with accuracy but I am more working out if I am right on the edge, which is where I want to be.

[rangieman]

They say a tune will help for best performance [wink11]
But it works very well on a standard tune no probs[thumbsupbig]

[ashleyhj74]

G'day all, first time poster (i think? cant remember, anyway, moving on....). I only found this thread after the group buy had ended so I paid "full price", and it was delivered in just under a week. I've got a 04 D2a auto, its got silicone hoses, someone else besides me already removed the egr, and i'll blame them too for the "ventilated" cat and large middle muffler removal [bigwhistle]. Its also got a Les Richmond remap, snorkel and K&N air filter (now, before anyone comments, I don't care in the slightest about your opinion of K&N products. I like them. I service them properly. I've had them in many cars over many years. No problems for me. I'll continue to use and buy them). Up until today, I was averaging around the 10-11ltrs/100km mark for fuel economy driving normally with the a/c on pretty much all the time mix of highway/town (on just the highway its easy to get into the low-9's per 100km). Car goes very well, quite a fan of it (when its running......another story, touch wood at the moment its running spot on.......but it is a Land Rover......).
Main reason for me buying the turbo was my old ones done just under 240,000km, i'm pretty confident its never been changed, so it was ultimately more a preventative maintenance thing (pretty sure my old one was leaking oil) and anything else is a bonus. I've got SAAS boost/pyro gauges, my old turbo would hit juuuust under 20psi, maybe just on 20psi. I wont go into the fitting side of things as there's some excellent info prior in this thread. So today was the first drive. First impressions, its very quiet at idle. My old turbo had a louder whistle out the tail pipe, but not so much from inside the cabin whilst driving. Its now the opposite, I can hear it quite well from inside the cabin. Its not intrusive or annoying (to me anyway), and turn the radio back on and its mostly gone. There's, we're only talking ass-dyno here with no actual figures to back it up, a noticeable improvement in low-mid range torque. The boost gauge sits lower at town speeds, with less throttle imput it seems (i'll take a note of the fuel usage over this week and try remember to post any differences here). Up the Ring Road hill near Geelong where I live (its a long, steep 100km stretch) its about 2-3psi lower (used to go 17-18psi, today it was 15-16psi) on cruise control. Exhaust temps seemed about the same, possibly a little lower at the posted speed limits. Maybe under full throttle to 100km/hr+ the exhaust temps might have risen a slight amount, but that's only after you've passed the 100km/hr (private road of course [bigwhistle]) limit. Look its only been a couple of hours with a bit of a test drive, but i'm happy with the initial "results". Technically if I am using less throttle/boost to do the same speeds it should technically give better economy. I'll find out next weekend when I top the tank up as my daily route to/from work doesnt change.

[AK83]

.... Technically if I am using less throttle/boost to do the same speeds it should technically give better economy. I'll find out next weekend when I top the tank up as my daily route to/from work doesnt change.


I always thought that if you had more boost, but still less throttle, you get even better economy than just less throttle alone.
More boost shouldn't mean more fuel used .. boost is just air .. but that would be ECU map dependent anyhow.

For sure your lower boost would be due to the wastegate rod length that its been set at, compared to the old turbo setting.

Didn't change the wastegate rod length mate.......

Oh and for the 248.60km I did yesterday from Geelong to Braeside in Melbourne I got 8.85ltrs/100km (I probably could get it better than that, but my right foots pretty fat and my tolerance for sitting behind people who cant do the speed limit is pretty low), never got into the 8's before. Quite happy with that all round [thumbsupbig]

Just to bring this thread back alive....

Fitted one to my D2a, stock tune, manual, 10P
*Starts to really pull at about 1800rpm.
*Whistles right up happily to the end (until one day it all lets go [tonguewink] ).
*I think on an auto it will be a good improvement.
*Pretty dam good result, price and worth it when comparing other options out there.
*Turbo Rebuild Limited are quick to respond to queries and quick to process orders.

Overall the stock TD5 turbo is a long lasting durable item and will see the life of an engine, but this is a nice mod to do.

Good to hear mine is still going strong and im still amazed by it at times [thumbsupbig]

[surfingooner]

As already said, definitely better mid-range torque, you suddenly find yourself going quicker than you were intending to. All very effortless and am definitely getting better economy. The times I have filled her up, I have been getting at least 60kms more driving around Melbourne's suburbs, and would expect more on cleaner roads.

[DazzaTD5]

Just yet another update to this thread..

*Fitted one to a customers D2a AUTO (member here, Gav).
*As I suspected, its a great upgrade on an auto, seems to pull along far more effortlessly and this way confirmed by the owner.
*On a standard exhaust its quiet and I couldnt pick any noticeable increase in exhaust noise.

*Again, this is a cheap mod with good results.

[Wicks89]

Just reviving this thread yet again to ask if anyone could provide any more longer term reviews of the product?

Also, how much difference is there with torque off idle and is it useful off road in crawling situations?

If anyone has any feedback/views on this I would be very grateful.

Cheers, tom

[kelvo]

I had about 20,000Km trouble free driving on my CHRA when I sold my D2. The new owner then drove it from Perth to Melbourne AFAIK he had no issues either.

My D2 was a manual and you could definitely feel it come on boost much earlier, especially in low range. Much better low down torque compared to standard using my arse dyno.

Definitely worth the money IMHO.

Yep mine is still going strong and yes you do notice the torque at take off and in low range is so much better .
I still highly recommend this [thumbsupbig]

[Wicks89]

thanks for your replies, it's always really valuable to get peoples thoughts and perspectives on mods a few years after the fact.

I'm seriously looking into it, should complement the 4.11 gears on my defender nicely and restore some of the oomph I've lost with the 35" tyres.

[County4.4]

Mine is on the bench in the shed waiting to be put in.
Doing a fair bit of work over the next couple of weeks to the defender.
New radiator, intercooler, CHRA, dewebbed manifold, engine mounts etc.
Hoping with the CHRA and bigger intercooler i get a bit more power.
I ve got a Td5Inside map is it worth getting this tweaked again? once tbe CHRA and bigger intercooler are in.

[INter674]

Bought an upgraded CHRA turbo from turbo rebuild UK on Sunday arrived inTas today!

Wonder why then it takes so long to get stuff from Sydney n Melbourne?

Arrived without the syringe. .but no big deal as everything else was there and well packed too. Probably confiscated by Border Farse☺

Wonder what difference it will make bearing in mind that since fitting the Ford Bosch fuel reg the car is going like stink and it already has a new late model genuine turbo fitted running at 18 - 19 psi?

We'll see...😎

Whats the advantage of the Ford Bosch Fuel Reg. Please ?



none really, just the xr 6 turbo bosch reg's are easier to get , same pressure


I've fitted a few of the upgraded chra , kilometres vary on vehicles from 15- 40 000 all still spinning away happily , but chuck the paper gasket for the oil return and fit a genuine one

Mario (Roverlords) made up OE gasket kits for fitting these Chra`s when everyone jumped on board originally [thumbsupbig]
Might be worth flicking him a PM[wink11]

[INter674]

Xr6 regs are German made..well mine was and are about the same bar. The aftermarket one from Tas is def hit n miss..2 have failed on me in 2 years.

Turbo is in and so far I have noticed less de-cat whistle on idle and above..mmm I liked that whistle too.

On driving it is obvious that pressure rises earlier in the rev range but tops out the same as the original.

Take off in the auto is slightly improved as is kick down with a little more push evident and at less throttle opening.

I guess with std tune not much else could be expected.

Overall despite the loss of whistle and as a replacement I would recommend it esp since the price n service is sooo good.

Highway test tomorrow which will tell more as on the hilliest bit I can easily hold 100 kph without kick down at @19psi boost.

So, it's a ford xr6 turbo fuel regulator ?

Is it a bolt in replacement for the td5 one ?

Do you have a part number for this ? Or a year model or motor part etc.

More information please ... :)

[Reddirt204]

Sorry, massive thread dig....

Looking at rebuilding my turbo in a few months, as mine is not in the best shape, how are these going 6 years+ down the track?

Anyone still around here with the upgraded Turbo Rebuilds CHRA?

A simple upgrade from stock would be nice, thought about VNT and all that but realistically, for what I want and use the D2 for, just a nice little extra is all I really need with enough room for a bit of a tune a little further down the track once I get everything else sorted first (auto has 380,000km on it and is showing signs of abuse)

Cheers

Redd

[shack]

VNT/VGT definitely better, but if you only need a replacement or something with a whisker better specs, the ones from turbo rebuild are good.

No issues on the quality front and do have slightly better performance than the stock one.

If anyone ever needed to replace their TD5 turbo and were going to go genuine, I'd definitely be suggesting/insisting to just go this way.

[Reddirt204]

Thanks Shack

That's pretty much what I was thinking, I don't need crazy HP just a bit more than stock. Also I can do this myself at home.
I'm also thinking the difference will be very noticeable as the current turbo is getting pretty tired coupled with a lazy/worn auto makes for a very uninspiring drive, plus I'm also running 265/70/17 BFG's so that doesn't help either.

cheers

Redd
