Skyline or M3
same question aka blonde or blackhair babe! M3 is about handling, fun, N/A engine which like high rpm, this is the charm of this engine. On the other side is Skyline, the turbo monster. I dont see any good reason for turbo set up for M3, sorry, I know that you boys from USA like it. If you like boost, buy Skyline, easy way for more horsepower.
