How hard is it to MS and FI a 12A? How about a Japanese spec 12A turbo should I want to do a swap?

 

The hardest part will be equipping the 12A and vehicle for EFI. Injectors, rails, high-pressure pump, regulator, throttle body... Some of these would be included with the 12AT, which would simplify things a bit.

 

TM makes a setup with uses the Weber side-draft manifold.
