R33 Turbo 25

wow, the thread got a little out of hand... lol. I found a split on of the hoses on the intercooler. This would explain why it was still boosting to about 4psi, and when I released the accelarator, the shhh sound was the air escaping from the hose and not going though the turbo. Thank you very very much for your input all of you. I cant express how happy im that it wasn't the turbo

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

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!
