Im not sure what relation RA168E has to street level performance. Unless of course your scope involves making the most out of 150L of super-duper-cancer juice at a maximum manifold pressure of 2.5bar..
You dont really need to look any further than DTM/WTCC for NA performance. Or WRC/Leman series for supercharged.
