The AT trans is going to be a major problem for 300whp . I know for a fact the older 4AT couldn't handle that much power. Not sure if they beefed up the 6 but ........... I doubt it.

 

None of that matters if you're swapping to a standalone. The only reason you cannot use the Adaptronic easily on an S2 is because of the factory S2 OMP. If you're swapping to an REW, just swap to a manual while you're at it. The adaptronic wont care.

 

Lol! Aren't I observant.

 

Well it’s not a 20B. That guy has a 13B Cosmo

nice idea about the manual swap, but I don't know if I can afford to do this at the same time, this covid thing crushes the USD exchange rate to my country, I think I'll need to postpone this swap to next year.
Anyway I just installed a coilover to this dying car, and it feels soooo good, I wish I have a healthy engine

 

the early auto harness is different than the manual trans harness though, not sure about the later one but maybe not. So you might need to do some custom wiring on a few features or swap it out.
