Putting a s4 tranny on a s5 engine

Do all you need to do is match the same series flywheel as tranny?

MIDNFauciUSN >> Yep! The engine/flywheel have to match, the transmission only has to be NA or Turbo-matching the engine. [But make sure you have the correct crossmember and Y-bracket for your transmission!]

The flywheel series must match the engine. (S4 to S4) (S5 to S5)

The flywheel type must match the transmission. (TII to TII) (N/A to N/A)

The transmission crossmember must match the transmission series. (S4 to S4) (S5 to S5)
