the 22re i have is "Junk" so i would like to get a sbc350 for it! so i priced it and i can get an adapter from downey for around $417, i could make my own motor mounts, and get a 350 for around $250!... what else do i need? will the adapter kit have everything ill need? i just want to make the swap as easy as possible! oh and ill make my own exhaust!

Thanks for the help!

its never as easy as it sounds... you'll find that out soon enough. you'll want to regear your axles, or that 350 will disintegrate them. and honestly, id put a stronger transmission in, i dont think a stock toy transmission will stand up to a 350 for long, especially if you've got a lead foot. it will also suck gas like crazy, i had a chevy with a 350, and that thing drank gas. on the freeway it got about 12mpg, and in the city it got about 8mpg. then again the truck was a 66 C10, and the engine was from a 71 camaro, but still. let me know how this goes, im thinking of doing a 350 swap sometime

Lots of bad information is thrown around about V8 swaps. Personally, I've helped do 3 swaps myself, 2 302 5.0's, and a Tundra 4.7 into a 92 Yoter. While it's not a direct bolt-in job...it's not rocket science, either. Sorry for all the long post here but some points are needed to be made.

-The biggest mistake that a lot of people make is trying to use Toyo trannies and rear ends with these motors. Toyota makes tough as nails parts...but they're NOT built to handle the HP and TQ that a V8 gives. Some people don't like it since it's not Toyota parts, but I would rather have something in that can handle the abuse. But, if you're a Yoter freak and just have to have Toyota parts...find yourself a R-151F, and don't go taking off like you're in the NHRA National Championship or some ...and it might last. The 8.8" rear end is around the same strength as a D44....so you're in better shape there, but then again...better safe, then sorry.

-Cooling is a bitch. But can be done while retaining the AC. Really, it depends on the motor you use. I will talk more about this if I'm asked.

-Frame reinforcement. Demello makes some...you can box the rear. Not completely necessary...but...well I won't say it again.

-You will more than likely need yourself some custom headers and exhaust.

Also, try to get a COMPLETE motor. Harness, computer...everything. Another thing that people try to do is try to use Toyota wiring, and Toyota this and that with a donor engine...that's all fine and dandy but you have to buy adapters for everything and it just ends up being a pain in the ass to deal with.

--If you can wait...either at the end of May or June I'm SAS'ing and swapping a stroker motor into my '00 Taco. The exact motor choice is still yet undecided ...but I'm leaning towards a LS2 Iron block 408...should be putting over 500 RWHP, ~530 TQ. I may also go with an aluminum or iron block 418 or 427...it just all depends.

a 418 or 427 into a taco??? have fun and good luck.... you are GONNA need it

Diesel_29

Well, it just all depends on how you look at it. A lot of people think I've done jumped off the looney bin a time or two when I mention the idea...but 2 out of 3 times, that's because they think I'm trying to swap a Big Block in. Which is the time where I think they've jumped off the looney bin themselves.

ozziesironmanoffroad

thats what i thought... a big block in a taco??? that guy must be out of his mind... lol.

I'm getting ready to start my 350 swap tomorrow. I finally got all my parts.

A couple things you have to figure out first. Do you want to keep the toy trans and transfer, or chevy stuff? Keeping the toy stuff will let you keep your stock driveline (if you work it right) Youll have a better gear ratio too, since most chevy trans/transfer have a higher gear reduction. If you want 5 speed, use a R150 V6 trans. You'll have to get a new pressure plate and custom clutch plate, about $300 for those. Bellhousing adapter can be had for $350 (Advance Adapters from www.rockbuggysupply.com)

i had an 86 standard cab with a mild built 350 and it was so much fun, i used a turbo 350/205 combo it worked great i used a short water pump and a 2core cross flow radiator, never over heated. the gearing was ok but i had 33" tires. the toyota running gear will not just explode. it holds up well. dont get me wrong i broke like 3 rear 4:10 3rds. but i was abusing them bad!2nd gear huge power brakes on dry pavement over and over.

theres a company out of bellingham,wa that specializes in v-8in toyotas... northwestoffroad.com they got everything you need

DudeBud

we all know about NO WARRANTIES OR RETURNS.. advanced adapters has more of a selection and way better customer service

Been there, done it. Easy swap with the adaptor kit (motor mounts, tranny x-member, etc...). I used a pusher electric fan out front to help with pulley clearance and to keep the distributor out of the firewall. Ran a Toy tranny with one for years with 42's and stock diffs. No problems but I didn't do burnouts or hardcore off-roading, just deep muddy pits in the swamp. My best decision was to keep the sbc simple...mild RV cam, 600cfm, longtube headers....maybe only about 250hp. If you go with most stock sbc's, you'll probably only push 175-225hp anyhow.

They over price their crap, have crap customer service and at least the parts of theirs that I had were crap quality too. You advertise for them like you work there or something.

chevota4.3

I have a very built 4.3 pushing 345rwhp with a th350 tranny mated to a toyota transfer case with stock running gear and it handles the deepest mud pits i can find all day long. your drivetrane will handle just fine..

TrikeKid

Mud puts far less strain on things than rocks do.

chevota4.3

yea but up here in michigan thats all we got..Mud sand and tree's

I got a 350 in front of a R150 toy 5 speed...handles the drive from the gas station back to my house...so far thats all the further I've been!

But I do believe the same style trans is used behind the MK3 Supras, and they are pushing a couple hundered horses on stock trans, so it should handle it.

I'm in the process of putting a chevy small block 383 stroker/700r4 with toy t case in my 85 4runner. I would like to keep a/c and not hack up my radiator core support. So far the only option I have found is a serpentine setup with the corvette short water pump reverse rotation. Anyone has something close too this out there? Any Pics? The cheapest serpentine setup I have found is made by www.alangrovecomponents.com .I have a 7 skyjacker lift with marlins extended shackles, soon to be installed 4crawler 3" body lift, 30 spline longs hp 3rdup front, 5.29's and detroits front and rear with high steer crossover.

I have a Quick question. What problems usually occur with the transfer case and rear/front diffys when A mild 350 and tranny are swapped in. I have heard that they will hold up and can take the power, but for how long????
If you used it lightly on the street and took it on the dunes and the desert occasionally would the axels, diffs and transfercase hold up well??

toyotajake

my 350 tore the outta my rear diff. I swapped another one in, but plannin on putting danas underneath i dont want it to happen again, but i need my truck for transportation at least for the winter, my motorcycle gets cold

murgle66

what is the gear ratio in your axles i plan on putting a 350 sbc with 330 hp and a 700r tranny and is mainly 4 street use will my stock axles hold up ?
