I had these installed- rebuilt 14b turbo. turbo timer, Greddy RS blowoff valve, intercooler,header, full 3" exhaust from turbo back.
Now it runs rich and fouls out the plugs and it has an idle problem. If you have any ideas PLEASE post!
Thank you, Frank

 

Out of curiosity, do you have a dump tube on that BOV, or are you releasing to atmosphere?

 

I have a dump tube

 

What are you other mods, Frank?

 

you are running a FMIC on a stock turbo? wow. if you are looking for performacne you are acutally better off w/ the stock SMIC. unels you are just piecing togethera build as you go... then its all good. does your car have a tuning device? (safcII, dsm link) or anything like that?

 

Those are all the up grades. It has no tuning device. Should I get one and where from?

 

well.. let me ask you this. are you a performance person? or a looks person? if its performance. you can either leave the fmic and start a build for a larger turbo. or you can get a stock smic and put it back on. OR i've heard of ppl using the Supra stock smic as a replacement and it's suposed to be much more effective. if you are a looks person, id leave it.
