here's my dilemma:

i just found a good deal on a JDM S5 engine with wiring ecu afm boost sensor the works...

besides my FD,

I own an S4 TII

and an S5 NA


would it be easier converting the S5 N/A to S5 TII (rear diff is different)

or would it be easier converint the S4 TII to an S5 TII? (dash harness is diff)


my S4 engine is on it's last legs I feel... probably due for a rebuild soon..
but the S5 is much better lookin then an S4

but the S4 is a lighter car...

hmmm decisions decisions...


what do u guys think?

 

I'd do the TII personally.

 

s4 i think. s4's are starting to become rare because ever one is converting to s5 bumper and molding . thats why i'm going back to my s4 bumpers and moldings before it goes to paint and just find a nice lip

 

ok S4 it is but,what about techincal issues?

any difference between the S4 and S5 Tranny's?

should i try to get the S5 wiring and ECU working in the S5?

or should i just convert the S5 Cover and stuff to the S4?
