Help needed!!

[GTRREX]

Hi guys,

I have a '97 R33 GTR with HKS GT2530 turbos. Earlier tonight I was having some fun driving it when I noticed that it started to feel a little "sluggish". I then noticed that the peak boost it had achieved in my last run was only 1.2 bar instead of the 1.5 bar I was getting earlier. I quickly pulled the car over and smoke was absolutely pouring out the exhaust. It was difficult to see in the dark but it looked like the smoke was white in colour. I lifted the bonnet could hear water or fluid bubbling in the radiator (don't know if that means anything but I haven't noticed that before). I also noticed a couple of strange sounds when I noticed the car was sluggish but I can't remember what they sounded like but only remember hearing something out of the usual. The car still runs but is now is running very badly so I just got it towed.

Does this sound like a blown turbo? If so can it be repaired or what's involved getting it fixed. If it doesn't sound like a turbo then any ideas on what has happened.

As I'm sure you can tell, I have very limited mechanical knowledge but am very concerned. I hope someone can help.

Thanks.

take the oil cap off and see if there is any blow by coming out , if it is you probably done a piston ( are they stock ?) 1.5 bar a bit on the high side for stock pistons .

if there is no blow by then you may have blown a turbo ( they are a nightmare to pull off with engine in the car ) did you notice it slugish after you gave it high rpm like close to cut out ? without hearing the engine is very hard to guees what is wrong with it but if i had to guess i'd say you done a piston ( for sure if you stockers ) what kind of computer do you have ? what other mods ? how much power do you make ?

you're dead right wrxhoon. I found out today that I broke number 6 piston. It uses HKS 2530 turbos and standard internals but didn't think I'd have a problem because I ran 1.5 bar boost for 3 years on my old WRX with standard internals and no problems.

Thanks for the reply!

yea sorry to hear , i saw your other post after i posted here .

wrx's are different though they love boost as they have lower compression than rb 26's , i have a rex too . did you have sti or normal rex ? sti's have forgies .

is the engine out ? or just a compression test and no compression on no 6 ?

do you have a power fc ? you see it could have been pinging , anyway you'll see the detonetion marks on the top of the pistons once you have them out .

are you going to rebuild ? dont use a second hand engine , it may or may not be good and then you will have to do a rebuild anyway so do it right in the first place .

if you need any advice just ask or you can pm if you like , been there done that .

good luck with it but you are up for big $.

what kind of power did you make with the 2530's ?
