turbo or not turbo

[sd25hardbody]

I'm always looking the differance betwen industrial and common sd25 but I's not the subjet....my question is, Is the td25 the same engine as a sd25+turbo??? if not what is the difference, and can I put a turbo on my sd25???

[weezle_deezle]

Turbo it!! Same answer I've given multiple times- more torque, better MPG, and the cool whistley sound...

ok, but do I have modification to do?? injector...pump...?? or I put the turbo and ....finish.

I know this thread has some age on it.
What source is a td25 turbo available from? I would like to install one on my 82 SD22.

The TD engines are completely different than the SDs.

Are you saying it will not work?

Who can say? Someone who knows both engines. That's not me, because I've never seen a TD25 in the flesh, as they were never sold in the US.

Just a guess, though: modern automotive diesels have better airflow (volumetric efficiency) than the old SD. I don't think that a turbo from a stock TD25 application would be a good size match for the SD, even if you have an SD of the same displacement (ie an SD25). Most of the SDs still running in the US are the 2.2l, not the 2.5l.

IOW, there has got to be better turbo choices around than a turbo from an engine that was never available in the US in any significant numbers.

K14 off a VW diesel, or some sort of similarly sized diesel will work pretty well..
