Ok so ilike an idiot agreed to help my friend replace his blown motor in his eclipse. It's a '94 gs-t automatic...the engine is siezed and he told me he bought a direct replacement. so we get the whole motor almost out(after splitting a halfshaft) and then i get a look at the "new" motor. It looks like its got 150,000 miles on it and its a Cyclone motor. This has got to cause some sort of problem. i have already noticed that the oiling system is diffrent but what other problems is this "swap" gonna have, and is there any good to doing it?
