I was going to do a engine swap but plans temporarily changed and I rebuilt the factory ford turbo and got it all hooked up on my 90 7.3 engine. I can tell a difference in power but ran into 2 problems.
When I rebuilt the turbo it came with a flat gasket for the oil drain tube instead of the rubber o-ring that was originally on it. It seemed like it should seal but I noticed after driving around it was dripping oil and I thought it was my rear seal at first and then found out it was this gasket. I tried tightening it quite a bit thinking it was just loose (its hard to get to) but that didn't help. I think I have to raise the turbo up to switch this gasket out for the o-ring?
My other thing is I no longer had the rubber seal from the intake to the round aluminum housing going to the turbo so I used the one out of the N/A air cleaner on the bottom but its not a real tight fit and the pressure is trying to blow it out.
Can I just get a thick o-ring this size somewhere or do I need to get ahold of ATS or someone to get one or Ford? I have noticed here lately when I go to get parts for this engine the parts stores don't have any clue what a factory 7.3 idi turbo is.
All in all I think it was worth my time to switch the turbo over once I get these problems worked out, it doesn't feel like the fuel needs turned up to match the turbo but I would think maybe it would be a good idea but have never messed with turning one up.
What was wierd was when I got all done my cruise and tach were not working. I messed with everything, fuses, wiring going to tach sensor and ended up removing the wiring at the solenoid and putting it back on. Now the tach works but cruise still doesn't. Can't figure that one out yet.
