I hate to keep
but I just can't believe that you went ahead and spent all that money rebuilding a engine with stock parts with even a slight chance you might want to mod it when like they said $700 and the sky would have been the limit for you.
Anyway you can still squeez out 250whp out of her just. Your gonna need basic turbo things a long with a walbro255hpl or some kind of performance pump. Something to tune iwth liek MSnS Emanage portfueller ect. IS you don't go MSnS missing link fcd FMU SMFU are all terms your gonna want to look into. Searching will educate you on all teh particulars.
All stock stuff on a full rebuild
sorry
