An engine swap will be inevitable as a matter of choice. The 3.0 is running very well but it's time will come. I have been looking into the feasability of swaps with either the supra or the 3.4. I know of the pitfalls and problems of both. I think. My runner is auto and would like to keep it auto. I was considering purchasing a R/T(rebuildable title) 4 runner. I can get a 97 for less than $5000. What pitfalls would this represent. As I understand it, the 3.4 auto swap requires the use of 5vze tranny to make it work. Why not get it in one package? Same questions for the Supra. If I find a 95 wreck I can scavenge it and use the required parts to complete the swap, but the engine works w/ the auto,right? As long as they are both autos to begin with. It seems the troubles with the 5vz swaps is the tranny unless you use a manual. If I am wrong please let me know. Right now I think the wrecked runner would be the best bet and most pratical. I just like the idea of an I6 w/ +300 plus hp. I don't need it, I just really like it.

Any thoughts...

I think I might be interested in your old 3.0. I've been thinkin' about picking one up, overhauling it, modding it and dropping it in next summer.

Oh yeah...I don't know why nobody here thinks about dropping a small block Ford in. It's narrower than the Chevy, decent torque and HP and there are lots of crate engines out there.

The output shaft from the transfer case on the 5vze is on the wrong side for the front axle. The exhaust is also on the wrong side as well as easier stuff like the gas lines and return lines. If you could switch the front axle over it might work, but with the newer runners having rack and pinion steering it gets very complicated very fast. It can be done with the 3vze auto trans but will require wiring from scratch. As long as you have dogged determination it'll work. There also maybe a wiring harness available from offroad solutions. They have been working on one for a while.

Off road solutions says you have to use the 5vze tranny and t/c. They do acknowledge the different drop sides but don't really offer a correction. The wiring harness they offer seems to integrate the 5vze tranny with motor and the body. It's all very confusing.

Has anybody produced an oilpan for any of the Supra motors to clear the front dif?

pretty much everything you want to know about the supra swap can be found there, also has a forum to search for or ask all the n00b questions you want . Do the turbo supra motor, it has more power stock than a S/C 3.4, costs less, requires a bit more thought, planning, and work but has far more room for improvement. you could do the N/A supra 7MGE if the turbo scares you. Its somewhat easier.

I agree w/ you. It is a tempting swap. I just want to keep it all Toyota. I have considered the GM 4.3 V6 as well. My dad says his pushes him back pretty well in his GM thing( the name escapes me, it's Friday some slack please). Anyway similiar size vehicle. It prolly gets better mileage as well.

If/when I do the swap I'll be more than happy to let you know about the motor. But I was shopping and daydreaming today at work instead of....working. I'm trying to work out the pitfalls of each swap and what would need to happen to make it a weekend deal, if possible.

if you get a complete parts car supra i would say its only marginally more difficult than a 3.4 swap, i bought my parts car for $1000 and it already had a JDM low miles imported motor. Worth $1000 by itself without the rest of the car

That is what I was thinking. Not too shabby.

Is anyone making the oilpan? I would be willing to pay for that expertise when the time comes. I can handle the all the trouble shooting,wiring and engine mounts but I don't want to mess with fabbing a pan and pickup tube.

make a post on the supracharged forum, rob (super-runner) would probably mod one for you if you sent it to him. He has done the swap on several IFS trucks. theres some pictures on the site somewhere, just look around.

i had a 302 ho sitting in a old bronco that wasn't gonna run, and my dad sold it for 300 bucks don't know why, told him that i wanted it for the yota not sure what he was , but with all the 's i thought he would get the clue, but i guess i didn't it into his head enough, so now im back to the scrap board :cry:

gwhayduke

You would probably be better off with one of the crate 302's anyway. You'll get one with matched goodies that'll most likely be more driveable than one you piece together from an old Bronc.

I used the original 3.0 auto 4WD tranny on both my swaps. with the stock transfercase.

we rebuilt the trannies and swapped out the output shafts from some spare 2wd 5vz trannies we had laying around....you have to swap the shafts to run the 3.4 torque converter. we also did some valve body mods and shift spring mods so that we get a better crisper shift.

the 2 trannies are basically all the same....the tundra and sequoia trannies are the same as the 3.0 and 3.4 tranny. but they are setup to run the more powerful motor.

for AUTO swaps. if you have 2WD...I would swap and use the newer 3.4 tranny.
for 4WD, you have the problem with the t-case being flipped on the wrong side if you used the 3.4 tranny.

for auto, you will have to custom make a part so that the speed sensor reads correctly...I dont know if ORS has made a solution for that...have they figured out how to make the TACH work yet?

btw...we did all the wiring ourselves on the swaps that we did...look in my sig.
