I got a real good deal on an s5 full setup and now have it in my s4 body. I am able to figure out how to re-wire this thing to run properly, but would it be a better idea to just swap over the s4 intake goodies and run the s4 ecu and wiring? I know it's only about 15 hp or so but I want my fc back soon so any info would be appreciated. thanks

im not positive on this but from what ive gathered to put an s5 into an s4 u would have to basically take a number of pieces off of ur s4 and put onto your s5 including front cover, so it would basically be a s4 engine anyway with alot more work, i would look into maybe if u could jus swap the wiring out of an s5 and put it into your s4 body with s5 ecu, it would prolly be equal or less work and would give u the 15 extra hp, and more hp per mode vs the same mod on an s4 due to the higher compression, and an s4 is a lighter body so ud be quicker then a stock s4 or s5, not sure if its that easy or if its been done yet, jus my 2 cents

btw i jus noticed the car u have listed, and i have an 86gxl with everything under the hood no title if u lived in ohio or nearby and wanted i could sell u this motor, its got 110 on it and ran good when detached, jus an offer
