You’re correct - evidently G20t means “touring” not “turbo” 🤣
I looked back in the magazine article I had seen, and apparently it was done somehow using a JWT T28 turbo kit, which is CARB legal. Not sure if the kit is still in production, but there’s an EO number for it.
Basically at that point it’s a S14 240SX with a SR20DE swap, no JDM required unless you want the Silvia chassis.
which is weaker than a stock KA24DE S14
considering the KA pumps out 150hp and 155 ft lbs TQ vs the SR with 140hp and like 135 ft lbs TQ in a 2750Lb car but ya S13 or go home at least for me.
