Sluggish R32

[040jqm]

After a night of drifting, my R32 has become real sluggish until like 4800rpm then hits like a power-band...

RB20DET

RB25 Turbo

FMIC

Walbro Fuel Pump

12psi

I am at a loss to work out the problem - can find no trace of a vacuum leak anywhere :S

Check you haven't melted your cat. I'm pretty sure mine is now clogged after a bit of a high speed workout and I've got the same problem.

I'm going to hollow it out today and see if it fixes the problem

EDIT: Just gutted my cat and the car is boosting like normal again. Only now it missfires

My plugs are old so there getting changed soon and that should fix it completely

cat doesnt exist - straight thru pipes...

grrr so baffled.... its like theres a leak - cos i can hear it spooling way louder than usual - buttriple checked it all and nothing

Check your knock sensor plugs haven't came loose/fallen off.

Hmm, sounds like you've blown an intercooler pipe off or something... or... I once encountered a similar problem with my old 200sx and found the nuts that secure the turbo to the manifold had worked loose (turbo was loose). Pulled it off, fitted a new gasket and some decent exhaust nuts and she was as good as gold :sorcerer:

sounds like either you have a loose bolt on the turbo or you have blown the turbo gasket. either check for any leaks starting at the turbo changes are it is just a small air leak

And what did you find??

It helps when you come to a conclusion to your problem to put it up on the thread you started for reference.
