Hi i have a 94 import wrx, it has a dump valve, stainless heatshielded induction and a de-cat pipe. Through 2nd, 3rd ,4th and 5th it's really smooth and responsive, but if i accelerate hard in first gear, right in the middle of the gear it's like a limiter comes in everything goes away and then comes back again? kind of like a go stop go again?

 

Had same problem. Check the Rubber hose thats Approx 3 in in Diameter that connects Intercooler to throttle body. Make sure its ok, and clips are very tight

 

wot does it rev to ?

hi i drive a 1994 impreza turbo and over hte last few monthes its lost a bit ov power small dead spots come in in 2nd and 3rd how could i stop this and how to make it more powerfull as as standerd its 220 bhp

 

The best thing is regular maintenance and super unleaded fuel/optimax, this will cure 99% of all problems with a scoob

If you have no joy with the fuel try checking all the air + vaccum hoses around the engine, my mate had a rover 220 turbo that had a similar problem and all it turned out to be a little 6mm pipe to the airflow meter

 

4 octaine boost id ring power enginering.

 

thanks i allready use optymax but ile chek the hoses

 

Unless its been remapped all imports should not just rely on Optimax!!

Octane Booster may be a pain in the a$$ but many feel a necessity!

Cheers
