What would be the best turbo set up for a mild ported 12A engine?
I am running a OER 45MM carb with dual MSD blaster 3 coils, 3 MSD 6AL direct fire (1 6AL per each lead coil and 1 6AL for trailing coil) and a 100 amp alternater. I am not familiar with the whole turbo thing so any input I can get will be appreciated. Thanks.

 

s4 will work, bnr stage1 s5 would be better. 3"exaust

 

Thanks Roto
