Other than the needing a bellhousing for the R154, intercooler, and motor mounts, is everything else the same for the swap? This is not counting the 2J parts that are needed for the install. I just want to know if the wiring harness, hydro fan, igniter, ECU, etc from a Soarer clip will work on a Supra. Is there a difference between an auto ECU and a manual one?
