My son has bought two first cars a 2wd 94 ranger and an 87 4x4 b200 mazda.
We are putting the ranger together as his first car.(runs drives).
The mazda has a blown engine, got it started and it sounded like two diesels having sex.
He wants to resurrect the Mazda eventually. It has 5spd manual and is pretty complete.

My question is what engines will mate to the Trans and install with little fuss. So we can keep our eyes out for a donor or running engine.

Thanks in advance for any advice.
