i've got a bog standard astra 190 turbo and the warranty is due up shortly, so thoughts are turning to boosting the bhp! what sort of increase in bhp can i expect from a k&n induction kit,and freeflow pipe?
A good start would be an exhaust and filter then a chip and maybe a rolling road setup. Do a search,theres a good report on a z20let getting cs3(iirc) from courtney,good power/torque gains to be had on the standard engine/turbo.
ta for that!found another site whilst having a mooch! zlet.co.uk if anyones intrested! i can feel my wallet getting skinnier the more i look in to this!not sure i can hide a two grand withdrawal from the wife! lmao lmao i'll have a go thou!
