ask Joz, as he's had it done He's used the 4EFE ECU and wiring on his, but for the best performance it'd be best to wire in the 5EFE ECU...you'll just need the 5EFE Engine, ECU, Loom, and make sure the throttlebody, coil, ignitor, starter motor, intake and exhaust manifolds and all other ancillaries are attached
