I am Re powering my 4.0L Auto EB1 1992 with a 3.9L Manual 1990 's' Wagon motor and tranz and whant to know if some of the 4L parts will go on the 3.9
like the Intake Manifold?

does any one know if the Intake manifold off an injected 4L will go on to an Injected 3.9L ?

I noticed that the 4Ltr manifold is a lot bigger and the 3.9ltr Manifold will this stuff with ECU because i am planning on putting the 3.9 Computer strait In where the old 4ltr one was will this work ??
I am also polishing the 4ltr intake Manifold so would hate to finish and find it doesn't go on the 3.9ltr lolz


also what other tings should I look out for?

Help would be great

Cheers

The EBI used the 3.9 in the first place as far as i'm aware.

If you are going to use a 4.0L manifold the accelerator cable's are different. 3.9 are a tad shorter then the 4.0L.
