I have a complete S5 engine now (thnx venomrx7). What parts do I have to swap in order to put the S5 rotors in the S4 engine? I am planning on swapping the rotors and the counterweights, but is there anything I am missing? Also, is there a difference between auto and manual? Are there any S5 parts that are better than the S4 parts that I will want to swap? I am already trying to swap the intake mani per this thread Here.



Sorry for so many Q's



Thnx

Andy

swap the stationary gears too because they are hardened and you can rev higher. i'm wondering now if the opr's are the same between s4 and 5?

regarding your s4-5 swap, get the s5 fuel pulsation dampner...there's no screw to fall out and cause gas leakage.

really? I know my orig. s4 pd had that screw and NO cap over it, and I luckily didnt have an engine fire when I lost the screw twice...I guess I like the screwless one more.

You need the S5 flywheel cause its what is counterweighted. If the S5 motor is the auto, you can use that counterweight for a lightweight flywheel.
