Hello people. Ive just got a zetec s and im thinking of geting it chiped, put on a BMC air filter, cat to back, up lifted cams, and a 4-2-1 manifold. Do you think it would be worth putting on a power boost valve. Any other tuning sugestions would be a great help.

Thanks alot

 

not sure what works best on Z-s's but try http://www.zsoc.com/forum/ if you havent already, tbh i dont think power bost valves are worth ought! would mod the std airbox also with a uprated panel filter instead of the cone! what about throttle bodies, or maybe a 1.8/2.0 zetec engine conversion?
