Turbo Glowing

[honkie]

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

Thats possible...or It could be running very lean and hence the exhaust gas temps are through the roof.

Hi zebra,

Thanks for the update. Yeah im thinking of getting a dyno tune and try to figure out what has gone wrong.

what did you set the fuel pressure at and what reg is it?

[bradsm87]

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 have a nismo reg. I didnt set anything because i havnt touched it since i got it fitted by my mechanic.

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..

Why you would even put an aftermarket fuel reg on there is beyond me...

Totally unnecessary.

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

Why not just diagnose the problem correctly and fix the actual problem instead of just replacing every possible part until you finally get it?

[mad082]

what boost did you put it up to?

[nfi]

Take any turbo car for a hard drive at night and pop the bonnet.

I wouldn't worry. Just don't turn the boost up to more than 10psi with the stock turbo.

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.

dude it's normal, go for a nice drive through the national park and it's enough to light cigarettes off. Totally normal
