Interest in Performance Parts for slants?

Hey guys, I'm headed off to college (IUPUI) for Motorsports Engineering. I'm just curious on the interest level in for performance parts for Slants.

I think I have a good idea for an intake manifold design, but what else would you guys I suggest looking into?

Just looking for ideas/requests/complaints on current products and seeing if it'd be worth designing/building parts for.

Gimme your $.02!!!!
