i have read in a topic somewhere that a guy tried to mod his b20a5.. got crower regrind cams, adjustable cam gears, header, greddy exhaust system, and custom intake and got nowhere but maybe 20 hp and spent close to 2 grand. not worth it really. make sure the engine is healthy on bottom as well as top and peice together a small turbo and run around 8-9 psi of boost...for 2 grand you will get more than 20 hp going with a good small turbo setup.

u wanna do intake, header, exhuast and cams right? i suggest doing compression test and leakdown test make sure your numbers are good u are looking at 175psi across all cylinders variation no greater than 24 psi each. no more than 5% leakdown. re-ring and hone cylinder walls. then do the bolt-ons. search google for your bolt-ons
