Dale, did you cut one of the studs on your exhaust manifold?

 

Yes, one on each side was cut down some to make it easier to get the nut on and off where the pipe bends back sharply. I did that while the engine was out a few years ago.

 

ok.....I have a 95 4runner and REALLY want to get rid of my 3.slow, done a little research but need things clarified, so ive heard mixed things, first that I could used the auto tranny in my truck with the 3.4? Also heard that I cannot, I would like to do the swap but from what i'm hearing and reading now is to do the swap I would need...
3.4
auto tranny 96+ and a gear driven tcase from an older taco with the output on drivers side to keep the ifs......yes I know I know, sas swap, just not sure which would be better to do first, since if I do an sas swap now, later I would need a different axle for a reg setup for a 3.4 and 150r auto tranny...
Any info tips ect. are greatly greatly appreciated

 

you can use your A340H 3.slow tranny with the 3.4 it just requires you to do the wiring harness conversion or have someone that knows what they are doing do it. i used to do them but im to busy with other things and it would litterally probably take me the better part of 6 months to a year to complete a harness not because it would take that long but because i have to many other demands on my time. if you want to use the A340H thats in your truck currently then u need to find a 3.4 out of a T100 OR at min. a wiring harness and ecu out of a T100. PM me if you have any other questions. As far as i know i was the first to use the A340H in its stock configuration with a 3.4 swap.

 

MT Goat- Props for doing the cleanest swap I've ever seen. So did this beast get a straight front conversion yet? I have a 91 4runner with a straight axle swap and I'm in the process of doing this swap. Thanks for the info and time writing on this thread.

 

Nope, probably never will. I'm pretty happy with IFS:

 

Just a little update, everything is running fine. The Marlin Crawler dual cases have an slight oil leak which drips on the garage floor now.

I've gotten a few PMs about MPG so this my best answer to that:

 

Hey Dale! Hows that cross over pipe treating you? Mostly I'm checking because I'm finally tackling mine and am concerned about the heat on the x-over. I wanted to check and see how that titanium ceramic coating was holding up now that you've had it on for a few months.

 

Hey MrDoug! Its been doing fine, no problems. Seems to be the way to go for sure Good luck

 

just a heads up, I pulled the engine and trans from my truck the other-day to put into a 4runner. (trucks got a bent frame, and 4runner had blown engine) Anyway i pulled the crossover off to inspect it just to check and see. and guess what i found. Yep you got it I found a crack in that Y. it was about an inch long and was very thin but it was cracked. ill post picks up tomorrow of it after i had it fixed. So you all might want to check those crossovers again. Especially since ORS isnt around to get knew ones from.

 

Refresh my memory Brian, was yours ceramic coated or wrapped?

 

Coated. Coated the brand new one that ORS gave me at discount for the messed up one. I took it knew from ORS in Arvada and drove it down to a guy that does coatings in Colorado Springs and had him coat then brought it back and installed it.

I wouldnt have known there was a problem or anything till later had i not pulled the engine. Crack very small but would have developed into something fairly large.


Crossover was Anchored to the side of the transmission solidly. Only thing i didnt do yet that ORS had recommended was put a 6inch flex in the pipe somewhere just after the Crossover.

 

Okay heres the picture of the crack after it was TIG'd. You can see the weld just inside the red line over where they ground down the original weld. The visible portion of the crack was from approximately the curve half way to the top of the red line.

 

Im a little concerned about the missing coating over the new welds. Although I'm going to build a new one for my trail rig and if that works out really well, i will build another and get rid of the ORS one. Im pretty sure the reason for the cracks is the tight bend at the top on the drivers side. it curves very tightly there and then goes straight into the Y. This allows alot of heat build-up. I think there is enough room to make the bend less tight and move the y down possibly. also the bottom of the crossover needs to be moved back towards the firewall more. Its current location is approximately 3 or so inches further forward then the original path of the 3.0. Anyway Ill see what i can come up with. New TIG welder/Plasma Cutter hopefully coming end of the week so hehe time to have some fun.

 

Well my ORS xover pipe is ceramic coated, anchored to the belllhousing AND I've got a flex joint just after that.

Sooooo, I'll keep an eye on it and post up if it too cracks. I sure hope not.

 

Everything is going great, just turned over 123456 miles last week, swap was done at 115xxx.

 

just finished reading the whole thread. you are amazing. hopefully i will have the patience ( and money ) to pull that off sometime. i would like to do a 7mgte though

 

Thanks, as long as its a labor of love you'll do fine.

BTW everything is going good, may to need new tires soon though.

 

wow so I also just finished reading this. What a book! I am also just starting my build. Found a 90 4runner with a blown 3.0. And am rebuilding a 3.4 that I got for 150 bucks!. The runner was 700. I do have a question though. Earlier there was a post about the evap. You stated you used the stock 3.0's?? This will work just fine? I don't have the evap box either so I was hoping it would work. Any other gotcha's you can think of? WOW what a nice build-up!

 

Yep it works fine, no CEL yet. Just have to follow the ORS instructions on how to connect it all up. Didn't I post those in this thread somewhere? That is a pop quiz lol.

EDIT: here is the instructions:
