Am I on the right path???? Lm7, stock cam, termX, gt45r (comp AR .70, ind 61.4 exd 82, trim 56, exhaust ind 73.8, exd 64.5, trim 76, turbo AR 1.00), stock manifolds, 2.5 od 18 gauge hot side, twin 7psi 38mm gates. Still need a fuel system. I think i need a walbro 4xx, deca 60s and regulator. Also need an intercooler and BOV. Goal is 500 whp through a manual. Quick spooling and done at 55-6000. Is this enough wastegate? I will be plumbing them back in down stream. I went twins due to availability and cost. And if one fails it might not grenade as fast. Thoughts and opinions?
