GTiR T28 turbo.

T-28, 60 trim 60 mm BCI-1 compressor in standard T-3

housing. 79 trim 53.8mm Inco T-250 turbine wheel .86

I'll give you what I know.

The R33 (and R32 for that matter) has a turbo which has a bolt pattern of a T3.

So it will NOT bolt on to a car that had a T28.

The internals are of a similar size to a T28 though.

All I know about the sizes is that the exhaust wheel is 48mm for the R33 and 42mm for the R32.

But ALL skylines GTST from R32 onwards, have a T3 bolt pattern.

Not sure about the R31's and earlier..

The GTR's have twin T28 turbos. the bolt patter is a T28.

However, they are only good for twin turbo set ups.

The T28's on the GTR's do not work that good in a single turbo application.

WRXKILLA...

Just incase you didn't know.. the skyline turbos have ceramic exhaust wheels.. so I doubt that they would be an upgrade for your GTiR even if it did fit.

Nope,

The GTiR turbo will take excess boost pressures.

I know many GTiR owners that have run 18psi and even 20psi on the stock turbo for long long periods of time as daily drivers and never had a problem.

Of course it isnt exactly efficient at those pressures. But hey.

My Mate Ivan ran a 12.3 with stock turbo stock pretty much everything. 20psi.

My car came back from a Particular workshop withthe turbo buggered. Bit suspicious. Considering I had a lot of other things done wrong too.

But I was running 14psi.

nice...

did you go back to the workshop to complain or anything.

yeh the Gtir turbo's don't have ceramic exhaust wheels so no problem with running over 14psi.. but like you said, above that and it starts to get out of it's efficiency range... especially with the top mount interheater that they have.

he he he, yep, gotta love the Interwarmer, I cooked Bacon & Eggs on it once! :D

Yeah, Umongst other things, They Cross Threaded an Intercooler bolt and ross threaded the thread inside the plenum, (where it bolts in), left a gearbox bolt out!, replaced my Nissan Oil Filter will a Coopers!, I now get some clunking noises from drivetrain since the day it came out, and of course my turbo is a littel buggered since it came out.

I think I mentioned in another thread somewhre which garage this was.

In Sydney's East.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
