I don't mean to knock you so don't take it personally, but isn't that power figure really Poor?

I mean I got a similar figure when I had my R32 with an exhaust, filter, rb25 turbo and 11psi..

and alot of guys get over 160rwkw with stock rb20 turbo..

surely this is not normal for an R34 GTT

unless it's auto.. maybe?

Nah its a manual not a wussbox :P

Ummm.. Im in Bathurst which is about 700 - 800m higher than you Sydney guys if that makes much of a difference. (I know it did years ago back in the Dark ages of carbys)

Let's clear something up here, R32 GTST, R32 GTR, R33 GTST, R33 GTR and R34 GTT all have ceramic turbines.  R32 GTST, R32 GTR, R33 GTST, R33 GTR have steel compressor wheels.  These turbos are made by Garrett for Nissan using Nissan tooling.  Although I have seen a couple of late R33 GTST's with plastic compressor wheels.  All R34 GTT's I have seen have plastic compresor wheels.  These turbos are made by Hitachi for Nissan using Nissan tooling.

I have never seen a problem with the plastic compressor wheels, it's the ceramic turbines that are subject to failure at high boost and/or temperature.

The type of turbo fitted has nothing to do with the overboost protection, its dependant on the ECU. :(

what tipe of turbos do r33 gtrs have dude (you sure know alotabout these cars)

:):cheers:

      ENR34 - Leaking Transfer Case

      By AdiR34 · Posted

      You guys are amazingly knowledgeable and I appreciate it all so much. I’m currently at the local RB tuning shop, getting her inspected and diagnosed, for the t-case debacle and everything else. I’ll keep you guys posted!

      Lets play a game - What is causing my oil consumption?

      Like @Dose Pipe Sutututu mentioned, 10W30 on a built motor would not be a great idea. As for the steel wool, we think alike as I went ahead and put SS wool into my catch can as per my above posts.

      I am going to chime in here and say that is very bad advice for a built motor, making decent power of 400kW+ Especially if the rings have been gapped on the looser side. The more power you make the heavier you need your oil to be to be able to maintain that suspension between the moving parts, if not you'll have journals and bearings making love and grenade a motor. Remember that all moving parts inside the motor aren't ball bearing and are journal bearings and require oil to separate the surfaces from contacting.

      ENR34 - Leaking Transfer Case

      By joshuaho96 · Posted

      ENR34 manual transmission transfer cases are 33100-23U00 which is shared with all of the R32/R33 GT-Rs and GTS-4s. And the C34 Stagea. Do not bother with automatics, that is a huge effort to swap and the car will be worse for it. And an automatic transfer case does not have the right housing for the shifter which comes out the back of the transmission and goes through the transfer case. I already posted my response on reddit but if you didn't see it there here it is: You have almost certainly damaged the transfer case, the only question is how badly. Nobody can tell you how bad without more information. If you have a giant hole in the transfer case pissing out all the transfer case fluid then you need a new one. If it's not that bad then the only question is whether you burned up the clutches. Drain the transfer case oil and inspect for metal on the drain plug magnet. Small black filings are normal. Big chunks of metal or a ton of black fuzzies not so much. Fluid should be nice and red. Any other color isn't great. If the color is reasonably red and there's not a bunch of clutch material discoloring it or anything like that you probably got away with insubstantial excess wear not worth trying to fix. If you have to rebuild or replace the transfer case keep in mind you have to pull the transmission to get it off.
