85 re-powering suggestions

[raiden]

I seized my 2.3l motor and am looking at replacing it with a 4.3L v6. I know this comes with issues but they all can be over come with brute force and holding your tounge right. Have any of you veterans completed a swap with success? Wondering if there is a conversion for the tranny as well or should I swap both.

'85 what? Montero or pickup? Differences in the engine bays could dictate other engines, though the 4.3 will work in both. Also, the 2.3L is a diesel. You could run a 4BT Cummins.

Montero,, Sorry got ahead of myself. Wonder if I put more power to the drive train will I need to beef up the tranny or diff?

 

[rxinhed]

The rear diff will handle a little bit more power. The front diff is marginal. The trans will not handle the torque of a V6, but does stand up somewhat to a turbo 2.6l.

Thanks RXINHED. I now know what direction to go. Now looking for 4.3L with 4X4 tranny.

 

[rxinhed]

Look for an automatic trans, easier on the axle parts.

Not sure if any on here have done the 4.3L swap but I know several have on 4x4wire. May want to ask there for more detailed insights, pics, etc.

Also check out Don Huysman's website for a write-up...

Also, there is an SAS solid axle V6 Montero SWB for sale in the 4x4Wire classifieds. Already done and a good price, too.

Thanks for the advice.. I might just buy a finished buggy instead of rebuilding this vehicle again. I have replaced the engine twice and the tranny once. I've had several 88's and 85's for swapping parts. Been a great buggy.

Hey Off-roader, I checked out that link and what a great project. It sure looked goon when all done. Looks to be a bit out of my comfort zone. Big job..
Thanks for the link..

No problem. There are actually many completed mitsu 4.3l conversions. Do a search on 4x4wire for more detailed builds....
