Firstly the larger throttle bodies are not a direct fit and will require an aluminium plate to be welded to the ACIS to fit the larger throttle body plus some minor machining. The throttle bodies used on the ACIS here are the Nissan 240SX TB, the Toyota 3SGE TB and on one internally standard 5EFHE, a BBK 70mm TB was used. This particular turbo 5EFHE only made 298WHP @ 28PSI with race fuel and IIRC, 230 pounds feet of torque.
