can it be done?

 

yes it can, will it be easy or fun? no.
youd be better off buying an s4 shell.

ill pm u /so i dont get in trouble for wrong section...10mm

 

ive done this, wasnt fun. we used the s5 ecu harness and intake. Its ran like crap and we used the mechanical omp and just plugged the electronic one into the harness and stuffed to the side in the engine bay or else it would go into limp mode... i know, it was haggard. the best way to go in my head is to use the s5 harness and ecu and get a safc to tune for the lower compression, i have a sneaking suspicion thats why it ran the way it did.
