swapping engine/tranny

kilo · 09-02-09, 02:26 PM

Hey guys, I have noob questions only because when it comes to turning wrenches I have no idea of what I'm doing

. I have a 79 model 4x4 standard with 20r and a 80 model 2wd automatic with 22r. What I would like to do is put the 22r and automatic tranny in the 79 4x4. I know it's doable and have a lot of time yet before I start. My questions are what should I expect as far as what's not going to fit? What should I go ahead and purchase to have ready for install. I'm taking everything off of the 2wd model that I think I could use for the 4x4. I could use all the help you guys can give!!! Thank you!

Are you trying to keep the '79 a 4WD? I don't think the transfer case can be bolted to the back of the auto tranny.

Yes I am. I have also thougt about leaving it with the standard tranny and if so what would be involved with matching the 22r with the standard tranny? I was told something about the flywheel would need to be changed out? These are the things I would like to know ahead of time so I can be ready. Thanks for responding KLF.

Maybe letting you guys know what my plans for the rig might help some? Wheeling only. Don't want to register or inspect. More hard/rock wheeling than anything.

you're not dong any hard wheeling with a 22r and and a stock auto.
won't hardly climb a driveway, let alone any hard wheeling.

You will have to find a 4wd auto trans, or do some weird-o divorced case something or other to get the 2wd trans to have a t-case.
You say you've never wrenched before, this might not be your best bet.
As for swapping engines... there are some differences in the carb stuff, and various little things that are different, but nothing to stop you from bolting it in.

This worries me on my plans. Is the automaic tranny not any good for wheeling?

That's kind of what I was trying to figure out. Wasn't sure how much work and cash it would be to do this. I would love to keep the auto but may keep it standard? As far as being a motor head about all I know how to do would be spark plugs and oil changes and such. I do have several mechanics at work that can help but they have never done anything on Toyota's and have several more friends that do know somewhat about these just not the particular swap.

It's not the trans, it's the lack of torque.
You get a tire on someting and pin the throttle, and the trans is at stall, and you might not climb what you're up against.
It'll be much better in 4lo, but still is kinda of a problem in a 22r/auto.

Go with a weber carb, and you'll not have to worry about the other crap.
keeping the manual trans is the easiest.
finding an early auto/4x4 trans and t-case is another option.

Thanks guys!! I'll keep it as easy as possible due to the lack of knowledge on my part.

You mentioned WEBER carb, any particular one or model? My service manager at work said he has one that he had on a jeep, that he has been building, that has mayber 4-5 running hours, a Progressive Weber 2-barrel that should only need a kit now due to sitting for a couple of years after having fuel in it. If it would work for me he wouldn't mind given a hell of a deal on it? Does this sound ok?

It will not fit, most people like the 32/36 for a close to stock carb. I went with the 34/34 and get about 21-25mpg on 31's and stock gears. People will call shins, but 10 gallons to go 253 miles is 25.3miles per gallon and the worst ive gotten was 19. Its HARD to tune, or atleast it was for me. Wristpin is the almighty Weber god here and will answer any and all questions you have. Alot of the carb stuff will just be useless vac lines and re-routing fuel lines. I say keep it until you figure out if you need another one. Theres diagrams all over... As for the auto, do a 4.7kit in whatever tcase you get to fit and as long as your in 4lo then you wont have to wrry about stalling out. Otherwise, go with the manual.

Thank you! I'll keep that in mind. Going to go ahead and go the manuel route and go from there.
