First off this is my first post, and hoping you guys can help. I bought a 93 idi na f superduty 220k miles rollback with 5.13 gears and a zf 5 speed. It has no balls and I highly doubt I could get it up to 70 mph (I haven't tried yet, still needs some new tires). So I bought a 94 f350 idi turbo with 87k to swap the engine with turbo kit in. But now I'm thinking since I'm going to do all this work if there is an easily upgradeable turbo I could install in place of the factory one. Any help would be appreciated!
