Wow, maybe I've been lucky (knock on wood). The car has been boosted for over 9 years (80k miles) at about 260rwhp without any issues (currently 146k and still running strong). I think you could benefit alot by going over to ka-t.org and reading up. There's plenty of guys on there running reliable 400rwhp (not sure on tq) setups. Goodluck!
