Has anyone had any experience swappin parts between the F3 and F4 engines? are there any interchangeable parts?

Almost nothing. I think the crankshaft sensors are the same.

I believe there is a slight difference in the air gap on the crank sensor. Email me if you would like more information.

Thanx for the info guys. I compared the parts list between the two engines and most parts are different although there are a few small things that are the same, such as valve stem seals. The cam sprockets look exactly the same other then the f4i's being lightened by drilling a bunch of holes. So I think there might be a bunch of parts like this where they have different part numbers but are actually interchangeable.

This is between an F4 and F4i. Make sure you are looking at the proper years. The F4 and F4i are virtually identical engines; the F3 and F4 car very different.
