there are no real problems that can't be fairly easily overcome, but there are many significant differences.
any properly set up rwd 3s wont starve of oil. there are tons of rwd 3s's in IPRA, the problem is people not knowing what theyre doing when they rwd them. tilting the engine wont do much either. there is no real problem with the oil drains, if you look at them in comparison to a 4ag, you will see that is not really the issue.
you can search my recent threads on toymods in the general tech section, there is a pretty good discussion on 3s oiling issues there.
basically, if you have a good sump, keep it full (and have an accurate way of measuring it). it should be fine.
turbo or not doenst really affect the oil issue either.
these are the only interesting photos of no.10 right now. its an empty shell in average condition with mis matched pannels and all mechanical workings removed. saved for the rear axle which i just threw in to do a test fit of the wheels.
looks like i will be raising the guard height a little bit.
