ok i want to know if its worth it to get a 2 fd shells and a 2- rotor cosmos engine&tranny( with a greddy manifold, fmic,rps clutch, and act flywheel) for 2500, i would still need windows, front bumper, front fenders, hood, the guy says that he will give me everything for 2500. but i really want to know if i would be able to run it hard and reliable, with all that stuff? also the engine has 20,000 miles on it.

and another question i was wondering if you could put a 13bt in the fd? because i herd that the 13bt out of the fc3s are more reliable.
