Anybody using the R5/P7 for racing?

Older post, but figured I would search before I made a new post... How about oil pan and motor mounts? Will I need a diferrent front end, tubular or can I get a oil pan or does it clear. The crank spacing appears to be not as much an issue today, what other things will I run into if I decide to do this? I have a couple complete ones found for a decent price, and Im very intrigued!!!! Any help? I dont really want to cut up my car though to do it....
