Ok so i have a stock 1985 gsl-se with a fuel injected 13b motor and i want to swap it out for a twin turbo 13btt motor, i originally planned for a v8 swap or s4 swap but i would rather go with the twin turbo setup if possible...so my question of course is, is it possible to do it and what do i need, i know i need the ecu but what else???
