Forged pistons and A.R.P and ballancing come to mind as well as droping compression. Top end well seeing it's forced induction. Just make sure everything is in top nick with GOOD valve gear including valve springs,H.P timming chain. Maybe roller rockers?? Bigger injectors will go along way to prevent detonation.Keep spark advance trimmed heaps until you dyno it.. Oh and think of a better efi fuel pump & maybe adjustable fuel regulator... While sump is off remember to weld a return line / pipe for oil return from turbo atleast 16mm..

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
