So when i bought my R32 GTS-T the guy told me he was only running stock boost, i had alot of questions for him and it slipped my mind to ask him how much stock boost is on the car.. Would anyone know? I've tryd to google it but it only comes up with GTR's. And how much boost is safe to run on a stock RB20DET engine? Is there any chance of me being able to wind it up abit with minimal supporting mods? Not talking 18 or anything.. But maybe 8-10? Thanks for once again putting up with one of my stupid threads. I'm getting there i swear! :wacko::D

Standard for R32/RB20 is 10psi

Can safely handle 20+psi in standard form (not with standard turbo obviously)

General consensus around here is 14psi is considered reasonably safe for standard turbo (could last days or years, no one can say)

To be slightly more specific, stock boost is 10 psi - that's what the wastegate actuator will give when everything else is stock.

Put on a big exhaust and the boost will probably go up a pound or so. Big intercooler with less pressure drop and you gain a bit more. It's easy enough to get to 12 psi on an RB20 without "changing" the boost setting.

Basic question: do you have a boost gauge? If not get at least a cheap second hand one. Are you are aiming at 8 - 10 psi because you are making less than that now? If so you have a problem! But If you want a few more psi than 10 you could buy or make a simple mechanical boost T.

      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.
