4-cyl transmission compatability question
Posted: February 26th, 2008, 3:23 pm
It looks like I'll be replacing, or rebuilding, my transmission soon and I have a couple of questions.
Can I replace my F-series with either an F5M-R from a '90-'92 protege (B8-ME engine), or an F25M-R from a '92-'94 protege (B8-ME engine)?
I want the 3.619 final drive ratio instead of the 4.105 that my current transmission has. All the internal gear ratios are the same, and my desire is to have the engine spin at closer to 2,500rpm at 70mph rather than 3,000+rpm at 70mph.
Does anyone know if the bolt pattern to the engine is the same on the B8-ME and the B6-DE? Also will my current axles and speedometer cable work? Has this been done before? I tried searching and spent all morning reading about the V-6 transmissions, swaps and automatic transmissions, but couldn't fine any info to answer my question.
Thanks for your time,
Vol!
