Hey all!
Tried looking for info on primary/ exhaust sizes for sch40 pipework to get good velocity/ flow/ heat for a g42-1450/ 79/75 1.15 turbo charger with v bands on my sbe 346 ls1?? Currently NA with 1-7/8 4-1s but want to fab up my own hotside due to cost of a complete hotside affordability??
Truck manifolds and 2 1/4" or 2 1/2" would work great and be very cheap.
Also maybe build it with a T6 flange with a T4 adapter so when you get bored of that 76 you're most of the way to upgrading to a better T6 platform.
