There is no doubt the stroker is expensive; and equally no doubt that the SC kit is FAR more bang for the buck. So if you're actually serious that you would consider either, then I would recommend you to drive both and then make a decision. The last guy who did that...chose the stroker and his motor is being built as we speak. He obviously saw something in the stroker that he liked better than the SC kit.
PM me if you have any more questions about the stroker, or want to take a test drive.
Stroker has fewer moving parts; less to go wrong (provided the basic build is done right).
Benefits of Stroker:
Stroker won't kick off as much heat under the hood; won't need an intercooler (but bigger oil cooler is always a good idea).
Stroker will have a purer "M3" sound.
The stroker that he drove may have had more low end torque.
ECU re-calibration should be more "set it and forget it" with the stroker.
Stroker is more stealth
Stroker should be more rliable with fewer moving parts.
Benefits of supercharger;
more tuneable - can change boost level/HP depending on need w/ pulleys.
easier to bolt on.
