I am biulding a 85 toyota with a 4.3 V6 and 4l60e tranny. the donor truck was 2wd. I have the toyota transfer case on the back of the 4l60e.

My question is: how will the PCM control the tranny shifting when I am in low range? will it work good? or will I need to put 4wd programming into the PCM. If I have to put 4wd programming in, what else as far as wiring wil I need to hook up? ]]> Domestic Swaps littlecars http://www.yotatech.com/f163/4l60e-swap-197220/ http://www.yotatech.com/f163/4-3l-swap-progress-90-4runner-5-spd-tbi-196819/ Mon, 16 Nov 2009 04:08:42 GMT I am working on a 4.3 swap into my 1990 4runner.

I have started this thread to give some info to people who are interested in doing it and to try to get some help from those who have done it before. I currently have the the motor in, clutch and transmission bolted up, radiator in, new driveshafts in, wiring harness started. :wrench:

What we are working on is finishing the wiring (help!), installing the slave cylinder, electric fan, radiator hoses, p.s. pump, fuel pump, horshoebracket/serpentine belt, cold air intake, exhaust.:stir:

I have some pictures that I will be posting up when I get the chance.

I have searched thru most every thread on yotatech, pirate and others I have followed links, etc,etc. It is easy to get info but it is hard to get definitive answers and pictures or descriptions of tried and true solutions. If you have done this TBI swap then please let me know what works. If you haven't done it please don't chime in and tell me "I should search the site..." If you are thinking of doing a swap and have questions I will answer as best as possible and try to get as much detailed info and pics up here as possible for your reference.

Here are the particulars of my swap:

** Probably best to get a donor vehicle. I wish we had. This is my first ever swap and I have learned a ton. But wish I had a complete donor vehicle to start with...


We are trying to finish this swap up asap as there is 6" of fresh snow on the ground and lots more on the way... I am stuck driving an 81 f-150. So it is getting urgent...

Currently we are having trouble with:

POWER STEERING: What is the definitive way to do this? What is the best way? Tried and true method?

FUEL PUMP: Considering my setup - what is the tried and true method? I am also going to add an 10 gal aux. fuel tank where my spare tire used to go just to let ya in on a little more info.

WIRING: aagh - where 2 start? Anyone specifically installed a Painless #60101 wiring harness on their 4.3l/Toy? Am stumped on the EGR solenoid (they said I need some pigtail??), Ignition wiring, how to use stock gauges with harness. Will this Astrovan computer even work right with the S10 motor? Any tips from wiring experts or someone w/ personal experience with the 60101 painless harness and a TBI 4.3 would b really appreciated.

A/C: While I live in Northern Idaho I like to travel to warm and even hot places... What is the tried and true method for hooking up the A/C to the Yota?

EXHAUST: Not really any problems here. Just not done yet. The manifolds dump out close by the bell housing and clutch fork but they clear. Planning on a dual exhaust if possible. But any tips or whatever is welcome.

ALTERNATOR: Currently I have a stock GM alternator but am considering a hi output 100A type. Any reccomendations on this?

REAR COILS & SHOCKS: And on one other note... since there are so many experienced yota guys on here maybe one can tell me what rear coil springs I should put on my rig? I have the 4" pro comps but they sag like a #$#@! and are way to soft for loaded - off road touring. If someone has a good tip on what length and which brand and where to get them...? Or should I just use a spacer? and which size/brand? Let me know (I don't want to go air bag). Additionally, while I am asking so many questions anyways, where do you guys get your bilstein shocks? Most everywhere has been out of stock that I have checked.

Knowledgeable members please respond with advice, tips, diagrams, photos, etc. This rig is our family DD and it has been out of commission far too long. I will greatly appreciate your help and also I will answer any questions for folks who are looking to get going on this swap. :great: ]]> Domestic Swaps biker1 http://www.yotatech.com/f163/4-3l-swap-progress-90-4runner-5-spd-tbi-196819/ http://www.yotatech.com/f163/tranny-196372/ Tue, 10 Nov 2009 00:03:49 GMT So I think the ol' Yote is getting a 302 dumped in finally and was wondering which transmissions some have gone with doing this swap. Was thinking either a t-18 or maybe c-4. I'm gonna adapt the Toy t-case in too. Anybody done it? Wondering about final lenght for t-case mount and drivelines. Greatly appreciate any input. ]]> Domestic Swaps YOTE8082 http://www.yotatech.com/f163/tranny-196372/ http://www.yotatech.com/f163/incoming-5-0-a-196296/ Mon, 09 Nov 2009 05:11:33 GMT i've finnally started my swap that i've been researching for the past year i'll upload photos tomorrow because im tearing the 3.0 pos out right now. ]]> Domestic Swaps DC Hoerunner http://www.yotatech.com/f163/incoming-5-0-a-196296/ http://www.yotatech.com/f163/4-3-swap-help-196223/ Sun, 08 Nov 2009 03:37:44 GMT I am new to YotaTech and I am planning on doing a 4.3 vortec swap in my 86 pickup.
