Just kidding. start by re torquing the head gasket to (damn I always forget,) 75? 80 lbs for stock bolts? then go ahead and just look in the faq, there's tons of topics and threads on this my friend, ill dig around and post a couple links and edit this post in a few. For starters just off my head, granted your motor is up to par internally (seals gaskets and the like.) upgrade your turbo or boost it to like 9-11 psi. upgrade your headers / downpipe / exhaust. and your at 300hp. congrats on the car and good luck.
