Just wondering if anyone is running a similar set up to my proposed one or if anyone could give me an approx bhp figure for these mods. The car already runs a trust system and k&n panel filter(soon to be changed to apexi intake). To this i would go for stillen headers, underdrive pulley set to release some bhp then from what i have heard a greddy e manage and a trip to thor racing is worthwhile. Would i be right in assuming that these mods on a good healthy lump would see 250 ish @ FW ?

Sounds about right :) There is a Non-turbo tuning section in the members area for Subscribed members ;)

leigh dont go for the stillen headers unless they have started making them for a right hand drive car.. what a pain in the ass to fit .. i dunno about power gains i havnt had mine on the rollers .. yet

not 100% sure but think chrissyp has got aftermarket headers on his NA

 

HTH

Slick Pete's yer man for NA advice - he's deifinitely got aftermarket headers but I think they were a barsteward to fit.

I think Suffolk ZX has them too - it's all in the 'NA Tuning forum'!
