:confused: 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?

between 5-10bhp realisticly i reckon both combined, you'll get more power from increasing the boost, although i dotn know much about the z20let so it might not be as simple as that.

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.
