I have had, in my dark past, 4 series landrovers. one of them a diesel.
I would, not put into one of them the turbo engine. I would pull off the turbo of a turbocharged engine and use it naturally breathing....
there are piston lube jets on the turbo.
and the horsepower with the turbo will wipe out your clutch, transmission, ring and pinions, "U" joints, rear axles, and anything else that can move inturnally or externally. Not that I want to rain on your parade...............
as it is, your stock horsepower is about 65, and the non-turbo will be around 85.
As it is, I have broken rear and front ring gears, 4 times, axles, 6 times, clutch covers, and worn out disks 3 times...
Ya think a fellow would learn!!
On the plus side, you will pick up 400 rpm, up to 4400 for the turbo engine.
vs. 4000 for the landrover diesel.
Good luck!
Dan.
