These should really have an electric lift pump mate. Your right about the glow plugs too.

If you want parts for one just get them all out of the US, most parts for these are quite difficult to source here. I really don't see the attraction in these motors.

Have you tried some wreckers and/or fleabay??
By the sounds of it, it looks like it is pointing the injectors, also what about fuel blockage in the line somewhere maybe check the filter.

Thanks mate.

Yip looking like injectors, could also be filter as it doesn't seem to have the power i expected especially at higher revs under acceleration.

That's just how they are mate. There really isn't much point revving them past about 2500rpm. The peak torque is around 1700 and is short lived. Jump on some of the yank forums and have a read. The injector pumps are not the most reliable due to their placement on the engine.

Wow ok, I might do that.
I changed the air & fuel filters yesterday, no change.
is it possible the governor weights in the injector pump are sticking.

How old is the engine?

Mat, I have seen a 6.5 in bits and I was pretty surprised in how small things were intake wise.

The ports in the maifold and the head were much smaller than a td42, to me they look very asthmatic, it this why they have such a narrow torque band

Can they be opened up to get more air in effectively?

To be effective with a turbo the entire induction system needs a rework the manifold would need to be completely redesigned. As for the heads it could be possible to port them out and aid in air delivery. These engines can't really be lent on to hard as I believe there biggest attraction in their simplicity is their downfall. There's only so much you can get from something with pressed steel rockers and very poor engine drivetrain.

In saying that what needs to focused on with our diesels is torque. You can't have hp or torque without each other anyway. We want to aim for fast torque rise and then a nice flat torque curve.
