As the title says, what turbo should I go with for my engine in my Sig? Forged pistons, and rods. Stock crank. I don't mind pushing this engine hard. I am prepared to run dual Walbro 255's, and will be keeping my injectors that flow 81/lb. If I need bigger injectors it will not be a problem. I would like a 4" inlet, 3" outlet. I would like the DP to be no bigger than 4" that I can put into a single inlet dual outlet muffler and out my tailpipes.

And I'm right about at 9.6:1 compression.

forged 370, i think a s475 would be a lil small, spool awesome, but choke out if you plan on pushing it. id look at a s478 with a billet wheel or even a s480. forcedinductions have a giant selection to choose from. 400SX-78R BILLET

If I was rolling with a forged 370 and wanted to push it I'd look s480. If building from scratch t6 would save you some money, but t4 will work just fine. Go with the 96 turbine and hold on man, it's going to move out.
