Need advice - going turbo I know I know, its a 6.2. But, theres alot more activity in this section of the forums so I'll ask here too. Going turbo soon, its 6.2 2000 Transam. 6 speed car, with an 8.8 in back.
Stock bottom end besides going .005 over with forged Wisecos. Will be putting in some forged rods
823 heads decked .030, stock LS3 intake with a 102MM TB
I'm currently planning on going with the ON3 or Huron speed A/C kit. I'm looking at turbo selection, and it seems I'm pretty limited if I want to keep AC and full exhaust.
#1 - Will a 7875 suffice with a 6.2, or should I see if I can shoehorn something bigger? Backpressure seems to be a concern on even smaller CI motors. It looks like there's a couple other larger options, but for a much heavier cost (PT88 for example)
#2 - Should I drop compression? Currently static is 11:1, I'm sure I can drop it down a bit with a thicker headgasket. Probably end up around 10.7:1. I plan on running a progressive meth kit with dual walbros in the rear.
#3 - For the fuel system, at these power levels is it mandatory I go to a true return setup, or can I modify stock fuel configuration to work? (Rail does not return, regulator in tank)
My goal is a healthy 700-800 to the tire with a nice curve. It's a T56 car, I would like to see the car go 9s.
Need some input from my techies, I know a bit but definitely no expert.
