hi i have a 1993 sc300 5spd, I'm planning on buying aristo 2jzgte with a auto tranny and iv read dr. tweak does good work so i was going to send my harness to him but i haven't been able to find out if i can still use the manual ecu or if i will have to change it so i can keep my car manual, or if there is any other modifications that need to be done to the engine to convert it to manual other then changing the tranny. thank you in advance for your help

 

il need the 6 speed ecu even if i have the 5 speed already?

 

You don't need a 6SPEED ECU, You can use the Auto ECU.

 

OP: Sounds like you need to do a lot of reading and research.

 

You can keep the auto ecu with 5 speed

 

Yes, you can run an Aristo automatic ECU on a manual transmission car. All the necessary wiring adjustments are taken care of when we do the conversion. The harness is plug and play when you get it back for your particular application.

 

I would go NA-T unless your engine is trashed. No need to go through all that rewiring hassle or the expense/labor of a swap. I have gone the swap route, and I can tell you now that I won't do it again unless my GE is totally shot.
