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

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.......Quote:

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.
Uprated Hybrid Billet Turbo CHRA Core 452239- Land Rover Defender Discovery TD5 Turbocharger Cartridge
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]Quote:

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.
