The SR20 comes as standard in S14 in our country, so there are quite a lot, and not so much build threads.

I can show you this one, although it had headwork ... and a very restricted exhaust. It did well over 450hp without the 5" long, 1.75" diameter jasma restriction. The dyno is a known pessimistic one, too.

You need to understand the gearbox wont hold that power level. You want a Z33 gearbox (like in this vid)
