Hi everyone

I just recently done some upgrades to my r33 series 2 including:

*front mount intercooler

*dump pipe

*splitfire coil packs

*fuel pump

*fuel reg

*hks evc 5 boost controller

After fitting in the boost controller, i tried to set it up myself by giving the car a hit to match up by boost settings but while i am doing so i found my turbo is glowing RED! Does anyone know what will be the problem? I still have my standard cat with a cat back exhaust and front pipe. Can it be the exhaust flow is not flowing properly due to the restriction of the standard cat creating the turbo to heat up?

Thanks

TELL ME you set the fuel pressure to factory specs with the vacuum hose unhooked on the new fuel pressure reg?

Actually even easier, unless u have a bigger turbo, I can't see u maxing out the standard injectors. Ur prob best to avoid the headaches and put the stock fuel pressure regulator back in. What did U want to acheive by puttin an aftermarket one in?

I havnt set any pressure since i got the reg fitted by my mechanic. Not too sure how he hooked it up. I gotta have a look. I have a problem with my car losing power and picking up speed very slow. Seem like a misfire of some sort. I changed my spark plugs first suspecting it could be that but it wasnt. My revs keep on jumping on idle so i thought it can be the coil packs and got that changed and changed my fuel pump as it can be that as well plus i would like more power haha =) Since i got my fuel pump replaced, might as well replace my fuel reg to compensate the fuel when i get my car tuned..

Fueling should be adjusted using a computer not a fuel regulator. Put the standard fuel reg back on and see if that changes anything.

Could be low compression on one cylinder, better rebuild the engine to be sure

My money is on the stock cat has collapsed.

When my stock cat collapsed (years ago), it blocked up and the turbo would glow WHITE hot after a thrash.

Even after all that super heating, turbo still went strong. Sold it on and AFAIK it's still going strong.

The nismo fuel reg could've come at ANY pressure. They aren't pre-set from factory. Most mechanics would b too dumb to set em as they'd just assume they come how they're meant to be.

Check fuel pressure or put stock reg back on. U don't need to compensate for a high flow pump, the stock reg does that.

      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. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. 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.
