Fash00

I have a 93 sc300 with the gte internals but still running the GE head and since my stock auto tranny wont hold the power and neither will the built BL NA tranny. How about this would it be possible to swap my wiring and computer for a supra wiring harness and computer and run the Supra Auto TT BL tranny? If not why? What wouldnt work or wire up? Only thing ive really heard thats diff would be the head in which case no big deal i swap to the GTE head. Please let me know as this seems to be my only option other then doing AEM and a BL built Auto which i dont want to do

Not a problem at all. You WILL need to get the Supra harness as well as the ECU, and there will be a number of wiring modifications to cross-reference the supra connectors to the Lexus in-body ones. Complete details in my manual.
