So a is the N/A transmission compatable with a TII engine? I've never done this so I'm not completely sure. Anyways I told him that he would have to change the flywheel and clutch assembly to the N/A parts. S4 N/A tranny with S4clutch assem+flywheel N/A and the same with S5. Anyways it is a S4 N/A tranny with a S4 TII engine. He doesn't have a TII tranny or rear end but he has the engine so this is why he wants to do this. I still suggested he change out the whole thing to TII though.

Also he was curious about if you could use the S4 N/A harness with the S4TII motor. He has a Jspec harness that is cut. What would one have to do to make the his S4 N/A harness work with a TII motor? I think the plugs for the injectors are gonna have to change to the ones on the cut JDM harness cuz the injectors are different form a N/A to a TII of course. Other then that what else would have to be done, he already has no AC or power steering if that helps. LOL

Thanks to anyone that helps and I just now realized I messed up on the title. LOL "on TII" is what it is supposed to say.

 

the n/a tranny would probably get torn up pretty quick under anything other than low boost. i would go ahead and swap out for the LSD from the TII if the other one is open ended. i think that the GSL is the only one that had a LSD other than the TII.

 

That is exactly what I told him but he wouldn't listen to me... He is going to run stock boost so I don't think he is gonna tear it up, it is gonna be his dailydriver...
