If your engine is that good, I would go ot somewhere like M.A.D (not too farfor you) get it chipped to about 14/15psi and get the fuel set up properly by Mark, add a decent air filter (keep the air box tho and drill it out, not a cone), -31 actuator, cam kit and your set for 180

Then cooler upgrade - bit more boost (17/18), headwork, decent leads and plugs and depending on Zorst your good for 210-215
