turbo size help
 

wanting to go with a budget on3 kit just wondering if there 76mm kit will suit my motor? forged ls1 6.0 heads. will spec a turbo cam. vic jr with low elbow and turbo400 in a fbody. no a/c and radiator is stood up. id love to run 17-18psi. like to see 700rwhp if the trans would lock but i know it wont read that with an unlocked th400. does this sound workable? possibly upgrade later but for now id like to stay on a tight budget. thanks for any insight im new to FI
