Hi all, just recently stuffed the rear turbo on my GTR. Sounds like a helicopter now as soon as any boost is raised. I've rung a few Jap import places and most have said they're pretty hard things to find.

Anyone been in this situation before and what did you do? I'm thinking a new turbo setup might be the go but money's tight at the moment due to building a house. Any suggestions would be appreciated! :P

This happened to me back in September. If it happened a week ealier, I couldve sold you my one working stock turbo, but its already been sold, sorry :P

From when I was pricing around I was quoted around the $800 mark per turbo to just rebuild and steel wheel the turbos (not highflow and no ball bearing). Rebuild, steel wheel and ball bearing to N1 specs was $2200 per turbo at GCG (ouch!).

In the end I got a set of second hand HKS GT2530's that were rebuilt in Japan by HKS (not rebuilt to Garret specs). Id say to save some pennys and either go replacements like the HKS ones, or rebuild + high flow + bb your standard ones.

Thanks heaps guys. Clint32, once I get the turbos off and get them sussed out I'll PM you.

We're organising a Group buy of Garret Turbos.. the prices are awesome, & haven't yet seen them cheaper anywhere else. Let me know, as we're trying to have the order put in by late jan, early feb.

I had been running 15PSI since I got the car, occasionally putting it up to 16PSI for the drags and cruises etc.

New years eve we went for a strap on an island with long straights on a private road getting it up to the 240km/h mark in fourth gear. Everything was fine until I slowed down then went to accelerate and I just thought what the f*ck is that noise....... worst thing I've ever heard. :(

We had to drive home about 100km at 50km/h (otherwise boost would cause that horrible helicopter sound), was quite strange having people overtake you like you don't know how to drive a GT-R or something. ;)

BTW, my car's only just done 70,000km now. And I'm pretty sure they're original km's coz everything's immaculate inside (and out). So don't be tempted to wind that boost up!

You were lucky that the turbo lasted as long as it did - stock R32 GTR turbos should not be run any higher than 14psi from what I have been told.

You can run higher boost on a stock motor (presently running around 20psi) but depending on the condition of the motor & quality of your tune it is also getting into the danger zone.

Thanks for the advice guys, I'm actually thinking of going to a single turbo depending on cost. I'd love 2530's or T51's but if I can get good response from a single then it's going to save me money in hardware.

Anyone converted from twin to single? Would you recommend it?

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      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

      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.
