Replace Egr with non EGR?

[Naga Sadow]

A friend of mine needs a new engine for his 93' sport. He currently has a egr equipped 4.0. He found a non-egr engine. Will it work? His state has no emission laws so it shouldnt be a problem but are the computers compatible?

'91 to '94 blocks are exactly the same, so you could use the block from the non-egr engine (assuming it's a '91-'94) in place of the existing block with no modification. EGR and all that other stuff attaches to the block.

Yeah as far as I know they are nearly the same except for the EGR and some other miniscule stuff. My buddy has a 1993 without egr, and I have a 1994 with egr. I can't find any differences between the two to mention. Should work great, one less thing to mess with.
