SD22 vs SD25

SD diesels were widely available in the US in the 1981-86 Datsun/Nissan 720 pickups, and in Canada through '87 in the D21 pickup.

Post by L-R Series 1 » 4 years ago

I had a 1982 SD22 engine that committed suicide and now i will be buying a 1989 SD 25.

Are there any parts from the SD22 engine that will fit on the SD25?

Keep the alternator with vacuum pump and the starter.
Not sure about the fuel pump however.
Valve cover may fit as well. Maybe water pump.
Not too much else you want to keep from a blown motor.
