differences between 4d34 and 4d33

Quite a few gt2860 turbos available on Ebay a lot are water and oil cooled. I take it that the oil line has a restricter built in to keep oil pressure up. I had a look at my Canter and I believe that it would be possible to use a U-bend from the bottom where the pipe runs from, back to the top to fit the turbo to. Is this feasible or is the turbo getting to far away from the engine as such ? Dan.

C'mon fellas I thought we were going to get a bit more info and comments coming as Looks like we may take this on as a project. I've seen pictures where the turbo has been fitted to a set of headers, the pipe work being 400 to 500 long that is why my previous question as to the distance to the turbo. Dan.

sorry, hadnt seen the other comment.
it will work, but is a bit sub-optimal. this kinda thing works on petrols because they have much hotter, faster exhaust to spin the turbine. diesel is by comparison, cold + slow, so to get best or better efficiency you really want the runners as short as possible, to keep as much heat in the gas as possible.
basically the heat in the exhaust gas is the energy your using to spin the turbo. so any lost heat is lost energy. as the hot exhaust passes thru the turbine, it expands + cools. thats the main reason for race cars etc having ceramic coated manifolds, or heat wrapped, 'turbo bags', etc.

Thanks for the reply. I had already thought about wrapping the bottom of the manifold and U-bend but we will keep collecting info. Dan.
