So I just found out my block are done. Now I on the market for a JDM LS or B20 to boost. I'm looking to only boost on the wastegate which is only 6.5 pounds (TiAL 38mm) but not sure which I should buy.

S2 70mm Throttle Body/ S2 intake manifold
780cc injector/ resistor box
Peakboost Turbo Kit w/ 60-1 turbo
Transmission will be a JDM GS-R w/ LSD

I heard B20B are really good on boost but I found both at the same price.
