This. Obviously if you engine isn't healthy, then that could be a factor as well, but if you don't care about the M badge, you can get as much if not more than M3 power with those mods. And all you need to do internally is cams.
Congrats on the buy. yes, maybe an M3 MAY have been better, but you'll have a lot of fun with your build. Enjoy!
