The Story:

I have acquired a 6.2 engine for parts. I didn't give much for it, considering is supposed to be a running engine and it was complete. The injection pump on this engine has recently been rebuilt. The engine was also at one time equipped with a Banks turbo kit. The owner of the engine pulled this engine from his truck and installed a gasser in its place, because it had lots of leaks (boy did it).I was also told the engine would start and run good, but just left puddles of oil everywhere. The leaks from my perspective were due to the turbo install and various other rigging (oil pan had 2 oil drains tapped into place, all leaking, and valve covers leaked badly, front main, rear main, timing cover, etc.). So I purchased the engine and got some other goodies with it, it'll be a easy fix for me to have a spare engine. The turbo was removed prior to me obtaining the engine. The kit is incomplete in that I didn't get the turbo because it was ruined and the owner threw it away (broken in half as I was told). I was able to get all the rest of the under hood banks equipment (pressure chamber, air cleaner box, tubing, gauges, banks ex-manifold, oil line and misc other parts).

Now the Questions:

Since this engine had a banks turbo on it I am concerned about the injection pump. During a banks turbo install the injection pump has the fuel metering screw adjusted to allow more fuel to be injected. The pump was recently rebuilt and I am interested in using it again on this or another engine but probably without the turbo. The question is, how do I determine if this pump was ever turned up and is so how much? Is there a way to turn the pump back down without being installed on a running engine? I just need a way to adjust the pump back down to a stock fuel rate suitable for a J series 6.2L. Is this possible without taking it to a stanadyne diesel shop and have it put on the bench?

Another question is about the banks turbo kit. Since I have most of the kit, where can I obtain a used turbo. I have a project truck with a N/A 6.2 in it that I am going to turbo and want some great HP out of. I am considering the MHI turbo that has been talked about here in the forums. I have seen a few 6.9/7.3 banks kits on ebay, but most are too complete to be cheap. I just want the turbo.

And finally, talking about turbos, since I have the banks turbo manifold. Will a 6.5TD turbo charger (GM5-8) work or be adapted to work? I looked at the turbo off a 6.5 (looked at mine on the suburban) and the exaust side of the turbo points down. I don't know if I can route the exaust downward and use a 90 degree turn from then on. Has anyone tried this? Also, this install will be in an 86 4x4 suburban, Just curious.

Thanks for your advice!
sorry for the long story!
