Schlib

I was wondering how much boost I'll be able to run effeciently with the AFC on a built turbo motor. Also, anyone know if I'll be able to adjust boost on the fly so it can be daily driver to V8 killer at the push of a button (or several)
I've got 450 cc injectors, should I get a walbro 255 lph pump? Since my engine is apart now, should I get any work done to my crankshaft? Is it worth the money to port/polish the head? Thanks much
