.010/.010 turned n balanced crank
Port n polished heads with .177 intake valves

Whats a good fuel pump for my application? Injectors and chip should be easy to get. Im getting a 2.1 scanmaster and knock guage this week. Should i upgrade the turbo?

Heads Combustion chamber first unshroud the valves you will get more out of that,then port and polish.

Is there a better turbo to use with the injectors and chip?

Most people say port and polish and dont unshroud the valves adding larger valves is not what i am talking about.

anywhere in the 60's as far as millimeter goes. if im wrong someone please chime in on this..

I think a 105mm would work out ok lol Jk. If you go to precisions website they have a list of their buick turbos and they list the specs of the turbo. You could match up what your trying to do with a turbo.

I just installed a TT chip from Eric last weekend, I did no adjustments to anything on my car and it has never ran this good!
