Daihatsu 2.8 diesel

Forum: 

Hi, Can anyone tell me if the factory turbo set-up on a Daihatsu Rocky/fourtrak diesel 2.8 will bolt straight onto the non-turbo motor. Any help would be appreciated.

Highly unlikely.

Inlet manifold and exhaust manifold will need changing. I don't know if the holes in the cylinder head are the same for turbo and non-turbo manifolds. I know the valves are different, so I guess the heads are too.

The exhaust comes out of the bottom of the turbo, so I bet the exhaust pipes are different too.

Finally, the injection pump needs to be changed for the one with the boost compensator to give larger injection quantities when the turbo pressure is up above atmospheric.

.... and this leads me to think that the injectors are different as well.

Might be easier to slot in a turbo engine, but then the gear ratios will be too low. It will pull the side off a house with the lower ratio, but won't cruise any faster.

OOPS, the radiator for the turbo is rated to shift more heat, so, yes, you might get away with it for a while, but when you ask your turbo-ised engine to work at full grunt, you will boil up.

Oh, that reminds me, the piston crowns on the turbo are cooled by little oil squirters that take oil from the camshaft oil gallery and squirt oil up under the pistons to take away the extra heat

Might be easier to buy a later 'trak with a turbo !

Just one thing to add. You

Just one thing to add. You would also need to change the aultinator (or at least the vacum pump on the back of it. The terbo engines had a 'slimline' pump, as the down pipe from the terbo goes through where the old style pump sits.
