I just got a 91 teg. Iam startin to build a ls/vtec motor for it. I want to but it on boost down the road. I am just looking to for the best crank. Should i just use the stock ls crank and get it cleaned up? I gonna be running JE 9:1 Pistons Eagle Hbeam Rods with ARP 2000 rod bolts Looking for somthing around 15-20 psi if that.
