if you want to continue with that engine, port+polish the head, and get a wider exhaust if you are runnning any of the stock peices its probably killing you making over twice the original power with a turbo trying to spool off the exhaust (but i'd cap it at 3", you can peice one together from kteller)


are you intercooled? you can definatly gain some power there


if you plan on pushing more boost i'd say open it back up, bore it out a little put in stronger sleeves.

if your rodbolts havent been upgraded already i'd think abbout that to along with a cam that runs slightly higher rpm's. you'll be able to take advantage of the boost better then


and he most important thing of all. a good dyno tune session. especially after any moderate to major addition
