90 4.0l into 92 4.0l

[bcw]

My 92 4.0l is on its way out and i found a 90 4.0l with just over 100,000 miles . Will this swap into my 92 and is there any known problems for the 90 4.0l.

Same motor, plug and play, 1990-1994 were the identical.

NO 1990-1994 are NOT identical

1990-92 ARE Identical

1993 is a unique year. (Different Injectors, but will replace a 1994 with a few minor changes (Addition of EGR and using the 1994 wiring harness))

1994 is also unique. (SEFI & EGR)

but a 1990 & 1992 are completely interchangeable.
