I hear that a 13BT Toyota diesel engine will drop right into a 1980 bj-44? It has a factory 4 speed tranny with a vacumme switch 4x4. I just bought the 13 Bt off of ebay and was wondering if it will drop right into my 1980 BJ-44? does anyone have any input?? thanks. I paid 3200. for the engine with turbo, alternator, bellhousing and clutch. Did I get a good deal? anyone know stock good compression for a 13BT?
