hello everyone me again!
after reading/posting threads about Tdi's vs 4bd1's and 4bd1T's i would like to see if anyone that has a tricked up 4bd1 and or 4bd1T is prepared to give it a test out against my dads 300Tdi defender? :eek: anywere within the vacinity of the hunter valley would be much appreciated since we live in cessnock :angel: anyways i will leave it up to yous were this test should be held (test will be to see what landy can pull up a long steep hill) if anyone wants any input on what they rekon should be done im glad to listen

I cant make the Hunter Valley, but a good mate of mine just drove a 2.8 international with VNT turbo in a Fender. Then he drove my RRC with 4BD1T which is custom I would say.

Lets just say I,m not going to trade the Isuzu in after his comments;). and the 2.8 is supposed to be a leap ahead from the 300.

I just wrecked a 300TDI disco and I thought the pump timing etc was out as it was gutless and very doughy off the mark. I,ve been told their all like that.:eek:

Just look at the bore & stroke figures. Simple really

What diff ratios are you running and what tyre sizes.
My specs are in my signature running 35's at the moment but if you want I'll stick the 29's back on!!!!!!!!

Drag race first?

Then we can get to top gear and see who can get over 150 the quickest (if we can find a private rd of course);)

Try then pulling a 1.2t float up a hill, how about the big dipper at Mooney Mooney? then how about a mud run up a hill, say suggie Rd when it's been raining for a fortnight?


How about starting at the top of a hill Say Mt Vinnie and only using the engine braking to slow you down?

Then we can do longivity (that race may take a while)

sometime over the next week will do me, so we can do it before the rebuild of the body and driveline that the engine has outlived

You have continually knocked the Isuzu, in numerous threads.

Myth be dambed! My rangie is off the road at the moment, but if you will wait till it is going again, I say to you put your money where your mouth is - my isuzu rangie vs your 300Tdi winner takes all.

And I will take a significant handicap!

Plus I am close to Cessnock.

Edit: the rangie is off the road for mods to make it into a camper. So it will have all my gear in it, so worth considerably more than your 300tdi.

I don't know what it is that others do not like about the ancient truck motor Isuzu but I also do not like it.
I am not sure why, the bearded people driving them, the noise or just the stigma?
My best mate has one and I pay him out constantly, everything has rattled loose, even his filling but he loves it.
Sure it has more power but so it should at almost twice the capacity and sure it will last but so will any truck motor.

I am not even sure why I bought a 300tdi.

I just like Landies I guess but the Isuzu thing just does nothing for me and most of the Landrover mechanics I use in this state also find them a joke but hey, I am glad some-one loves them.

Oh and I wish the 300 would whip the suzi but I can't see it happen.

yes the 300tdi is gutless compared, there i put an end to it:p

You honestly think a stock 300tdi will out perform a intercooled 4bd1t? How dilusional:angel:
The other day i follwed Rovercar in his, i was in my VW transporter, 128kw/400Nm, i couldn't catch him, was basically even, and this thing leaves our 300tdi disco for dead, which has been fueled and boosted:(

4th August 2009, 07:40 PM
MYTH??? Is this a wind up?? You're 'avin a larf Guv!


The fact is that yes a 300Tdi MANUAL, boosted and fuelled will most likely have a higher TOP speed due to its ability to revout past 3200rpm:p, BUT that is where it ends laughing boy:D

I wouldn't waste whatever measly amount of diesel it takes to 'whup your Tdi Butt'.

LOL thats funny, i guess you only have one friend and he's a mechanic. but as to why the "bearded people driving then" go i would assume because most of them have driven around this island at least a couple of times. drive over large mountains in L2 at idle, fiord small Lakes in L3 and have at least 300K on the clock ( 400K in my case) or maybe it has something to do with the bald patch on there Jaw from dropping Roos at 300 meters and pigs at 3 meters, can wip the head of a brown as quick as you can blink. where in your case a trip to the servo to get a lollypop on a wet night is the biggest adventure you will ever have. but then i would say your good at handling your snake:wasntme:

300tdi = car engine, zoozoo = ;ight truck engine. No comparo really.
I drive a 300tdi.... but have no probs saying the zoozoo would win, hands down.

Back in the old country they used to put 4236 (?) Perkins in rangies..... this would be more of a direct trial for you, chief.

I have a RRC with TDI 3.5L nissan truck engine, I have also spent loads of time driving the isuzu TD and non T's I find the 300tdi and td5's thrashy to drive in comparison and annoying at highway speeds (in manual). Any engine can be made to go fast, I would put money on some 1.5L turbo's vs stock new v8's but thats not the point, you also need the engine to last a long time. These 4 cyl truck engines give good power and also do 800 to 1m km before a rebuild. Mine is also good on fuel so they are actually a good deal, the 300tdi is also good but my money would be on my car or a 3.9isuzu over a 300tdi in a race.

Well your not prepared to back up all your brash talk as winner take all.

So I will still put up my rangie if you agree to pay $5000.00 to a charity of my choice (Camp Quality). $5k would not even come close to getting you even the suspension on my rangie.

If you can't come up with $5k, just how much will you back up you big mouth with?

dobbo

So he's got nothing to worry about then

Plus as I have been told I cannot drive for ****

Honestly though I don't think a single drag race can cut it to determine what engine is best perhaps a staged event taking all into consideration, cost of servicing, fuel consumption, drivability over various terrain, towing ability, outright speed, acceleration, engine braking etc......

I'll be in for sure, if we wait till Bush65's rangie is finished, it'll be even more entertaining. If we're not racing for pinks whats the prize?

I do like the lolly pops. How did you know?

You sound like a real man. However you have no knowledge about me and my life. I travelled most of the world, incl stint in Israel in a Kibbutz and Israeli army, tracking Egypt and South Africa. Servos there also have lollypops so you got that bit right.

Lets not get our dicks out and start swinging them in the breeze.

Lets also not take ourselves too seriously cause life is way too short for that.

I know you love your Isuzu and so be it. Enjoy it and live happily ever after.
I dislike them for some reason, bit like soy Latte's but that's just me.

So pull your head in bud, its just an opinion and nothing personnal.:)

about 3 weeks....

I have had my pump put back to factory limits as it was running lean and I have a slightly bigger intercooler...so I got mine down to around 2.5weeks:D

The battery ran out in my stopwatch :lol2:

Found this which says 18.5 seconds. Presumably auto.
Land Rover Land Rover Discovery TDi specifications (http://carinfo.autold.com/car-land-rover_land-rover-discovery-tdi.html)

Given my 4BD1T with slow shifting 5 speed truck gearbox does better than that. I don't see the contest.

IMO a 300tdi tweaked to within an inch of it's life will give similar torque but slightly higher power than a stock 4BD1T.
A 4BD1T tweaked to the same standard will deliver close to twice that of the tweaked 300tdi.

What are we allowed to change?
Turbos?
Intercoolers?
Fuel pumps?
Can we call up Carcrafter in the US who blew his Isuzu head gasket with 60+ psi boost?

A 4BD1T with just tuning (i.e. screws turned) can deliver ~200hp with no intercooler. At 2000rpm I can put 100hp to the ground.

I found a spec for a PUMA 90: Performance: 0-60 mph in 14.7secs.

This would presumably be the fastest stock diesel defender/discovery.

Who here has a 4BD1T which beats that?

Not if a v6 commo can better 500 HP :D

Edit: But then again the limit of the 4BD1 has not been reached yet, so v6 commo will probably need to do better than 700 HP to be sure.

c.h.i.e.f
5th August 2009, 11:02 AM
wait my bad the latest sv6 commodore is producing 260HP or 264 metric HP so in other words the 4bd1T is 150Kw (200HP) when the new defender isnt making that much power and it has had hundreds of millions of dollars spent on the development ;)

well that proves that it has a loud turbo whistle and that americans are prepared to goto extreme lengths to prove something but who on this site has had there 4bd1T tested on a qualified dyno? because knowing quiet well that a 1986 5 speed standard 4bd1 produces not even 50HP well something very special must be done to achieve more than 100hp:o

The strength limits of the 4BD1T haven't been found yet.
We have a guy who's popped head gaskets with 60+ psi boost. AFAIK he replaced the head gasket and is still driving it.

The bottlenecks are:
1. Stock fuel pump seems to be good for only 140 cc/1000 shots of diesel.
2. Getting enough boost to burn that cleanly.

140cc/1000 shots of diesel burnt cleanly at 3200rpm is going to give almost 200kw.
You need north of 30psi and a very good intercooler to get enough air in at that rpm.

I don't have a qualified dyno. I have a man-made viaduct of which I know the exact slope.
Which is why I know I've got 75kw (100hp) at the wheels at 2000rpm in 4th.

You can do the maths yourself.

Nothing special, just more fuel and enough boost to burn it cleanly.

ok yep that does equal 100HP but im sure there will be other factors to take into consideration in about 1 min i will hav the exact specs of the 4bd1 and 4bd1T direct from isuzu ill see what that has to say to wether im incorrect and if so ill stand defeated:angel:

ok ill stand corrected at the moment the figures show 4bd1T at 79kw@3000rpm and the 4bd1 66kw@3200 rpm but it still doesnt explain why the 300tdi will pull over the gap (freemans water hole) in 5th and the 4bd1 would be back to 3rd;)

You're looking at industrial specs.
Automotive 4BD1T is 100-105kw stock.

My 100hp to the ground is not my peak power. It's just one point on the curve.

From wikipedia:

The 4BD1T is a turbocharged version of the 4BD1, it was produced from 1980 and was fitted to Isuzu NPR trucks from 1986 and sold in the US. Approx 100kw, 330Nm There were higher specced versions than this AFAIK.

300Tdi in disco spec is about 83kW and 270Nm isn't it???

He was driving around town so couldn't test it fully, and the engine was putting out so much power the torque converter was slipping.

Power and torque from a diesel is directly related to how much boost you can put in (given enough fuel). As you spotted, he was getting 60psi of boost (almost 4x 300Tdi spec), and producing too much power and torque for any clutch or torque converter he has tried to-date.

To end this, how about some 300Tdi owners and 4BD1T owners do acceleration tests themselves and post up the results.

thats a good idea can we throw in a long hill climb as well ?
oh and to get things straight im not completely bagging out isuzu's me and the old man would just like to see how the 4bd1T goes compared to the 300tdi so another thing would be if anyone around my area would like to take us for a run in there 4bd1T to show us how it goes that would also be a resolution to the problem :angel:

Okay, I'll bite.
4BD1T (1985-6 truck version).
85 Rangerover, 29" tyres, 2.3T empty.
15-16 seconds for 0-100, runs an Isuzu 5 speed box with a 1:1 LT230. Would be much faster 0-100 with an auto.

The strength limits of the 4BD1T haven't been found yet.
We have a guy who's popped head gaskets with 60+ psi boost. AFAIK he replaced the head gasket and is still driving it.

The bottlenecks are:
1. Stock fuel pump seems to be good for only 140 cc/1000 shots of diesel.
2. Getting enough boost to burn that cleanly.

140cc/1000 shots of diesel burnt cleanly at 3200rpm is going to give almost 200kw.
You need north of 30psi and a very good intercooler to get enough air in at that rpm.
For your info:
My IP was sent to a shop for a tune up.

On the test bench, with governor removed and rack adjusted by hand, it delivered 180cc/1000 strokes.

With governor back on it could only deliver 170cc/1000 strokes. But profile of torque cam could be modified to get 180cc/1000 strokes.

My P&B's are 9.5. It looks like 10.5 P&B's as used in the 4HG1-T IP will fit - waiting for price.

I have asked for 200cc/1000 strokes. I think I will have enough air, so should perform ok.

I think Randy may have had 8.5 elements (now 10).

I have started on an exhaust manifold and want the HP compressor located before doing much more on the intercooler (short pipe across rocker cover between compressor and IC).

DaveS on here used to own a RED county with a tweaked 300Tdi which is now owned by Pete (Red October).

When Dave broke his neck doing a superman impression on a mountainbike, I drove his 110 home for him, then got a lift back to pick up my (then NA) 4BD1 RED county.

So - this is about as close as it gets!!! 2 RED countys of about the same vintage with different engines and R380/LT85 5 speeds.

There was a huge difference in low-down torque (in the 4BD1s favour). Only when you really wrung its neck on the highway did the Tdi shine over the NA isuzu.

I went from a 4.2 Stroker in my County to a 4BD1T and the only thing I miss about the V8 is the exhaust note. The Isuzu Turbo is a much more versatile engine.

My current rangie has had 4 different engines. In chronological order they were/are:
1. original high comp V8 - tried cams, extractors etc., but performance was never acceptable.
2. 4.6 litre rover V8 - also had a cam recommended by JDM and extractoers but performance was still dissapointing.
3. 300Tdi with VNT turbo producing 22 psi boost, largish water to air intercooler, tuned injection pump - wanted diesel for long trips to remote areas, but performance towing into headwinds was not good enough.
4. Isuzu 3.9 litre 4BD1-T, which I pulled out of my bushie after fitting 6:1 ratio diffs (bushie will get a high reving light weight engine on lpg, after the rangie is back on the road).

I know that I don't need more than 4 cylinders. And despite what JC said earlier in this thread, no 300Tdi will get near the performance of this 4BD1-T at any part of the speed range :twisted:.

I have just towed over 2t over Mt Vincent (the hill mentioned by Chief earlier in the thread) Freemans to Brunkerville I hit the Freemans roundabout exiting @ 70kph in 3rd gear, hit the governs and into 4 and foot to floor after roundabout, dropped back to 3rd just past the nudie camp, dropped back to 2nd at the steep section where it forms 2 lanes, crested in third and kept it in third all the way down.

Return trip, (no trailer full of horse jumps, poles, etc....)

Started of out of a driveway at Brunkerville 20m from the bottom of Mt Vincent, got to the governs in 3rd and switch to 4th at the Mt Vincent sign, held it till approx 200m away from the servo and switched back to 3rd to crest.


Personally I think this acceptable, slow but not sluggish. For the record the reason I was towing the trailer was the 3.0td Hilux used to tow it had to drop down to low range to crest the hill. I would like to see a 300tdi do the same task any easier

Sounds like you should own a 300Tdi then :D ;)

In all fairness though, a 4BD1 only just squeezes into the engine bay of a 110, and a lot of jobs are a huge PITA - like adjusting the pump timing...

Dead flat road would be best - that way we can compare with others. Time up a hill doesn't help unless everyone is on the same hill. Not many flat roads around Dayboro though...

OK, so far we have:

0-100 times on a flat road:

300Tdi (n=1) = 17 secs
4BD1T (n=2) = 16 secs
4BD1 (n=1) = 48 secs (sounds very slow - something not right there)

Must be a few more people who can improve the stats?

Based on two runs on the flat tonight (after a late run to the dairy for some milk) 15.6s and 16.2s.

It was about 2 degrees though, so that may have influenced things :)

1994 Disco 300Tdi, 285kms stock as a (big purple) rock. NZ model though so never had EGR etc. Have adjusted the torx screw and lock-nut, but only 1.5 turns - no serious playing around with it as yet. I think there is a bit more to come too, as it never smokes even under hard acceleration or off idle. Surprised me - seemed to rev to about 5k before it shifted into second?

As for the argument - several 4wd`s ago I had a 1994 Isuzu Bighorn with the 3.1TD... That engine (before it blew up) was super torquey, shame about the heavy as lump it was inside though.

Mechanical injection, intercooled, turbo charged... If they`d relocated the ancillaries (alternator in particular) to suit the 4wd application it would have been damn near perfect.

We didn`t get the Isuzu powered trucks over here, but Isuzu trucks have a pile em high sell em cheap reputation - not pleasant to drive (i.e. chosen by accountants who run transport firms not drivers.) Not sure a noiser more vibratory 110 would do much for me though - but I did drive 40k kms in a B diesel powered series 2a with no soundproofing...

I wouldn't say that. NZ's best selling light trucks for the last what, 25 years?
The Isuzu powered landies were sold here, just not in any real numbers. I remember the 6x6 Isuzu powered ones being advertised in the Rural News.

Isuzu powered landrovers are smoother, quieter, faster and better than toyota powered 40's. The people I knew with B powered cruisers wouldn't drive faster than 80km/h. Noise and vibration was far too much.

The pile em high sell em cheap (after building them cheap) mentality is why they have been NZ`s best selling light truck - think Toyota Corolla... I`ve driven quite a few (big and small Isuzus) never by choice.

I`ll take your word for it on Isuzu powered landies, but I can`t say that my old 2a with the B vibrated much more than a normal series landrover, and it would cruise at 100km/hr all day.

The family business has a now 25 year old NPR. In 25 years we've done front wheel bearings, rear gearbox seal, one cam follower and two door hinges.
All the other trucks from that era are dead and used a lot more fuel before they died too.
Toyota dynas, mitsubishi canters, daihatsu deltas (same as the dyna), they're all gone. Yet the NPR's from that era are still $6k, even with ludicrous mileage.

No commercial truck from 85 was a pleasure to drive.

Have had a Citroen Picaso as a hire car a couple of times. It seemed familar to drive however it took a while to figure out why. Then one day it struck me it was an Mitsubishi Canter of the mid eighties. Well at least the lack of connection between steering wheel and where the vehicle was going plus the gear change which was very much a matter of a randon selection basis if a lot of attention was not paid.

At least Citroen has added moved forward a little by adding some sound proofing. Although the quality of the interior fittings was higher in the Canter.

Read most of this thread. Interesting. Had a 86 Isuzu powered County for 11 years from 88. I think I pioneered the gearbox mods to fix the input bearing failure problem on the 5 speed.
I turboed and intercooled it and boosted it to 20psi and also put a a ford AOD auto in which has mechanical 3rd and 4th. 12lb boost at 1200rpm. High ratio transfer gears and big overdrive on AOD - 32%. Car is till going strong. I hear about it every so often. Since I sold it in 99 I have had 300tdi in 130s and a disco and now I have had an Xtreme for 8 years. I loved the County for its sheer brute force and towing ability, but the xtreme with the TD5 is the best by far. Mine is chipped, gassed, upgraded intercooler (4 times original capacity) 19psi boost and opened up the exhaust so its 2.5" all the way through. It lugs down low and goes like hell if you want it to. It pulls away in 5th at 45kph. It will cruise happily at over 150kph with low EGTs. (Done it once to try it out) In saying that if the 4B was still an option I would still have one cause I don't think you could break it or wear it out and the limits of a TD5 aren't really known yet.

do tell more about this ford AOD:)

The ford AOD box uses the torque converter in 1st and second and in third and fourth bypasses the torque converter completely with a shaft that effectively links the box with the crankshaft. This is great for engines like the 4BD as low engine revs and high torque generate lots of heat through a torque converter. Also there is no vacuum modulator, just a shift cable that connects to the throttle. Fitting it is a bit of a pain depending on how you look at it and how mechanically adept you or your mates are.

Engine adaption.

1. make an adapter plate out of 20-25mm steel or aluminium to adapt the box to the engine. original starter motor and flywheel are left in situ.
2. Make an adapter hub which mounts the drive plate to the flywheel at the correct spacing.

Transfer case adaption.

1. remove extension housing on auto box and have an adapter made to mate to the transfer case.
2. Using a tailshaft female spline which suits the AOD machine the transfer case input shaft/gearset out and press fit and weld the spline.

Obviously these 2 operations are dependant on each other for spacing, dimensions etc.

The transfer case ends up being back a little so the mount bolt holes in the chassis need to be redrilled and the front and rear tailshafts lengthened and shortened respectively. To clear the gearbox the front tailshaft has to be remade from smaller diameter solid material.

Fiddly bits

1. A B&M shifter or similar needs to be fitted.
2. The difflock/transfer lever sits further back so a new cover has to be made for the opening on the trans tunnel. I made mine out of leather that matched the carpet.
3. there is a bit of fiddling necessary to get the shift cable organised so that it has the right travel ratio with the throttle.
3. a great big tranny cooler is required.

AODs were not fitted to Aussie cars as far as I know and mine came from the states, but parts are readily available and getting them rebuilt locally is not a problem at all.

Overall the conversion was brilliant and totally changed everything with the car. It quite simply became the lazy mans 4WD. With the outstanding torque and power of my engine it was always just point and shoot. The only disadvantage was steep descents but judicious brake usage handled that. Another option to consider with a conversion like this is a manual shift kit.

One thing I did forget is that I found it necessary to have 1.22:1 transfer gears otherwise the engine revs were too low in top gear. not to pull the car, but to cool the engine.

I would convert my TD5 to auto but the torque its developing would trash the sprag clutch in the standard ZF.

20psi on an intercooled 4BD1 would easily beat any TD5 with 20psi.
You'll get over 200hp (150kw) at 3000rpm and over 600Nm peak on the Isuzu with an intercooled 20psi and safe EGT's.
In comparison doesn't the TD5 run 20psi stock with 100kw?

Lara in Belgium has a TD5 he's spent a lot of time and money on, he's running a 2.8L stroker kit, large variable vane turbo with 1.8 bar (28psi) boost which delivers 590Nm.
I don't think he's disclosed power figures.

Well, the ZooZoo is looking good so far. I just happened to time some runs in my 300Tdi 130 the other day for my own interest.

'96 Defender 130, 31" tyres, empty.
R380 5 speed with 1.41 LT230. GT2556V variable turbo with full size 'Alisport' intercooler and fueled up.
0-100 17+ seconds.

Murray

One run so far in a 130CC fully loaded (tares out at approx 2660kg) running 33" MT's, 300Tdi, stock turbo, fuelled up, boost pushing 16.5/17psi, 3" exhaust.

0 to 100Km/h in a high 19sec from a standing start. (the road had a slight hump in the middle).

Going to try it again on another, flatter (but grippier/deader) stretch of road.

No. I believe 14.5psi

18.04 and there's more to come, but I don't know if the clutch will take it :D

I think that's what the ECU limits it to if there's a sensor failure, otherwise it's something like 18+psi.

This link from BAS says 14.7 although does reference slightly higher pressures in Discos in certain conditions

Early next week I'm off to pick up over 100 fencing strainer post with the 120 and a car trailer.
Should make it grunt on the hills;) I wonder if she will hold forth gear:D
Will be over 500 kmh round trip. It does this over and over with no fuss.:)

Wish I could say the same about the 300Tdi, but I tend to hold my breath everytime I give it a big rev.

I had to go to Nundle one day last week, then Ellerston the next so she got a workout over both passes (Crawney and Sergeants Gap) and, well, i give it to her but part of me is cringing and waiting for the big BANG at any moment. :eek:

My D2 is running 1.34 bar, easy to get overboost in cool air.
Just ordered a ASE intercooler upgrade.
It has HEAPS of grunt already.

Went up North last weekend to pick up a damaged D1. Towed the empty car trailer easily at 110 to 120, drove back at an easy 100 to 110 with Disco on. Used 100 to 110 litres for 814km round trip, and loved keeping up with cars on the midland highway, even overtook a few....:twisted:
