I have an 85 mr2 that I have been looking at doing a 3sgte swap. I want to do this without being a crazy expensive build. Hopefully do it at home for about 5000 maybe 6000. I would like a 4th gen 3sgte with an s54 transmission. I would like it pretty much at stock power levels. Here is the plan.


Engine: 1000
Transmission: 800
Prime performance kit level 2: 2000
Prime performance mounts: 700
shifter relocation kit: 300
2nd gen NA axles: 200?
shift cables/Alternator bracket/throttle cable: 250?
unexpected random shit: 500

All this comes in below 6k but could easily get to 6 thousand. Is this realistic? My biggest concern is how doable is this swap these days with the "kits" that are available? Do the prime performance mounts need to be welded in? I tried looking into this and I found one youtube video and one post on mr2oc that implies it will just bolt in. I am super excited and looking for some honest input from the people that have gone through the journey I am starting.


After thought - I can also sell the 4age I pull out to help with some of the costs.
