R33 Gtst Something Went Wrong Please Help

[R33 Turbo 25]

hi guys i'm new here. I recently purchased a r33 GTST pretty stockish has a exhaust and front mount cooler and 10psi boost.

I red lined the car today for about a second and something made a slight metal 'ting' sound and now the car drives funny.

The car is completely normal to drive under no boost, however, when you step on in, it only boosts to about 4psi and the induction sound sounds different to what it did before.

also, I didn't have a BOV on my car so it used to flutter before, now, when I release the accelerator, it just makes a funny 'shhhh' sound from somewhere.

I checked all the pipes and simple things like that, but I couldn't find anything?

Could anyone with knowledge about these cars shed some light as to what it might be?

I've tried searching and have found nothing unfortunately.

thanks and peace!

Either the exhaust or compressor wheel in the turbo has shit itself would be my guess.

im not 100% familiar with RB motors since i am very new to skylines and very rarely work on them but im a mechanic and it sounds like maybe you could have bent one of the butterflys in the intake.

seems to add up to me because the lack of blow off valve would have left excess pressure in the intake when you backed off and a bent butterfly would cause lower vaccum pressure which would then in turn affect the wastegate actuators.

Also, running no BOV could potentially weaken the (nylon) compressor wheel of the stock turbo

Definitely intercooler or BOV related issue IMO.

You have either popped off a pipe, split joiner or broken the BOV. Should start trouble shooting.

His is a GTST, not a GTR, therefore it has one butterly, not 6.

Anyway there really could be a number of possibilities and without knowing the full story every one is simply going to be guessing. Most likely sounds like a small boost leak though.

as i said im not extremely familiar with the engines, i own a gtr and was going off that.

wouldnt it be good to go off a mechanics guess??? even though it is over the internet

check my option out first, its the easiest, and costs nothing.

[PM-R33]

It hasn't bent the throttle body butterfly on a stock GTST, I will gaurantee that.

[Trozzle]

if induction sounds different (quieter) then boost leak more than likely wouldn't be it....

[ben3322]

ive seen it on non turbo cars mate.

[PM-R33]

ive seen it on non turbo cars mate.

Cool.

Doesn't change the fact he hasn't bent the throttle body in his car.

Thanks for the opinions. I don't think it would be a boost leak, if it was wouldn't I get boost spicking? Also, I would still get some sort of flutter or bov sound even if it was a boost leak yeah? But thanks again guys, will check the butterfly tomorrow. But if it was the butterfly wouldn't the car run funny the whole way through not just on boost? Thanks again

[ARTZ]

they have a habit of cracking exhaust manifold studs and turbo bolts coming loose too..

Well thats what was wrong with mine anyway..

nah it would still run normal because the computer would compensate.

when i say bent i dont mean bent in half, i mean a slight bow in the butterfly.

[75coupe]

one thing Ive never seen on this forum in regards to gtst is a bent butterfly...

I hear what your saying Ben, but that doesnt explain the loud ting at WOT.

Something has broken or split at full power , trozzles idea sounded more plausible..

Or as i said my turbo bolts wound themselves loose and i was having these same symptons.

If your lucky its just a leak somewhere..Keep looking
