waking up a dead thread -

I searched, and I know people have it in their signatures sometimes, but what does it take to put an F3 or (dare to dream) F4 egine into an F2 frame?

I found an F2 that's completely set up for racing - even sprung for my weight - but the engine is blown. Can I just get an F3 engine off ebay and bolt it right up, or is there more involved?

 

Lol i pay 96$ a year for insurance. Not sure about the swap
