Unusual R33 S2 Problem

[Trevorm]

Hi all havn't posted for a long while Recently fitted a Blitz fmic to my fairly standard r33 (11 psi boost eahaust & power fc) Since then the engine refuses to rev over 3000rpm going flat & fluffy almost like a rev limiter) The best advice (from just jap & others is to replace the std ign coils which i have done with spitfires

have also changed spark plugs Made no difference Has anyone got any ideas

Pressure test intercooler pipe work.

Sounds like Air Flow Meter is not plugged in.

Thanks for your help guys airflow meter seems to be plugged in ok will have a look at the a/f monitoring with engine running on the power fc if ok will make up some blanking things & pressure test i/c & pluming

Wouldn't expect there to be a problem with brand new blitz i/c but we will see

Thanks again

I also wouldn't expect a problem with the actual intercooler, I would expect a problem with a joiner or clamp. You will be amazed what leaks when you pressure test.

thanks again i will pressure test with interest

Right on the money Ben the short silicone hose on rh side of intercooler (as viewed from the front) had moved slightly before tightening & leaking quite a . I think pressure testing would be worthwhile thing to do after any i/c install

Cheers

Glad you sorted it.

Once you pressure test you realise how crucial it is.

yep perhaps somebody could write a tutorial on the subject
