All is up for sale, and listed at 1 grand OBO.

I have a 1991 22re with 5spd tranny, and was wondering if I could swap out the transfer cases and mate it to my tranny.

I have read so much about this stuff on the forums and confused myself more than educate myself about it.

I do think the grand they want is going to be to much, and may see if the will sell just the transfer cases since I have no use for the tranny. ]]> Offroad Tech crafthorse http://www.yotatech.com/f31/questions-transfer-cases-duel-set-up-197099/ http://www.yotatech.com/f31/awesome-weber-price-197075/ Thu, 19 Nov 2009 08:19:56 GMT Didnt know if this was the right forum, but it seemed to fit.

So, I need a new carb, was looking for Aisin, but Weber has always been an option. While searching tonight for my new carb I stubbled upon the website Weber direct. The price for the conversion on their site is wicked. I talked briefly in chat with Elton, he pointed out the same company with an Ebay listing for the same kit, same price, but free shipping through ebay. I think friday I am going to order the carb. I was just wondering if anyone has dealt with company before, if so, feedback is welcome. Im not looking for the anti-weber guys, or even pro-weber guys. I am going to try this out and see how it works for me.


Here is the website for these guys.

So here's the story: I bought an E-locker from a wrecker who assured me it had the correct gearing. It didn't. Now i got a pretty good deal on the locker so i don't really want to send it back but i need to swap the gears to make it usable. The truck is a 1990 Pick-Up with a 22re. Can i switch the gears from the open diff in the truck with the gears in the e-locker? (e-locker was out of a '97 runner i believe) Now from the searching i have done, i can do this but i want to clarify before i get the diff out of the truck.

Thanks in advance,

Luke ]]> Offroad Tech LukeWilson http://www.yotatech.com/f31/regearing-e-locker-196909/ http://www.yotatech.com/f31/86-4runner-help-identify-rear-suspension-196784/ Sun, 15 Nov 2009 23:00:26 GMT my 86 4runner has a lot of lift and the rear is not flexy at all. there is a 2" block, looks like some helpers. what can i do to make it flex better? and keep the same height plus maybe a little since it sags a but in the rear. Here are the pics. thanks any suggestions for the front as well. good up but not good compressing. I will be putting in the creeper joints but I need to know if it would be better if I get a new rear spring pack or take out the flat heavy duty leafs and put in a set of bigger shackles.

i wanna be able to fill car/truck and bike tires, possibly run air tools and definitely run a train horn.

the horn needs 150 psi to operate and im not sure what a air ratchet takes..

would i benefit from buying a train horn kit and adapting it for tools and a chuck? ]]> Offroad Tech eighty5yota http://www.yotatech.com/f31/onboard-air-help-196782/ http://www.yotatech.com/f31/new-plug-play-ecm-diy-196687/ Sat, 14 Nov 2009 16:06:47 GMT I received an email from DIYAUTOTUNE this morning regarding thier new plug and play programmable ecm's for countless models including alot of Toyotas

The way I read it you just pull your old ECM and replace with the one that is correctly configured to run your factory spark and fuel...
The possibilities are awesome!!

I finally finished rebuilding my motor and transmission. Took a while because I tried to replace most parts, or sand blast them and repaint. Finding time was hard, having paddling practice 6 days a week.

Anyways, I'm finally ready to get started on my suspension. This is a 1990 4runner.

In the rear, I want to get rid of my my coils and put in leaf springs. Can the hanger and other parts be made myself? I have 24/7 access to the largest machine shop in the state, and I already have my navy and abs welding certification. If anyone could help me with planning the fab work, that would be awsome. :D

In the front, I was told to use drop brackets. I'm not the most knowledgeable guy about suspension, but is this the mount that holds the control arm (the big U pipe looking that that goes from the driver side to passenger side)?

I would guess that if I did this, I should find a stronger control arm? All I need to know is how exactly I make this give lift, and I'll make the strongest drop bracket you ever seen. :wrench:

I wanted to gain 4" of lift in the front, and get leafs that give 5" of lift, so it should even out.

Any help is appreciated! ]]> Offroad Tech HIrunner http://www.yotatech.com/f31/drop-brackets-front-leafs-rear-196457/ http://www.yotatech.com/f31/powertrax-hmm-196301/ Mon, 09 Nov 2009 06:43:25 GMT hi im looking into buying the powertrax no slip locker for my 1998 tacoma. i was just wondering if anyone has used on of these and there opion or if... hi im looking into buying the powertrax no slip locker for my 1998 tacoma. i was just wondering if anyone has used on of these and there opion or if there is already a thread a about them if you could direct me in that direction. im basically wondering how long they they last if they break often or if there is a similar but better product. im also making sure that my truck is a 30 spline rear axle shaft it is a 98 v6 4wd auto trans so any info would be a great help thanks ]]> Offroad Tech RPM122 http://www.yotatech.com/f31/powertrax-hmm-196301/ http://www.yotatech.com/f31/dual-case-my-91-3-0-60-40-seats-196281/ Mon, 09 Nov 2009 02:03:05 GMT i never thought i would have my stock 91 truck as 4x4 capible as it is today.

I still think this system... Some of you have seen my 4.3 swap thread where I used the megasquirt fuel and spark control system with very good results.
I still think this system has great value for eliminating the AFM and opening up the air flow on the 22re and other engines... also the ability to tune for power at any rpm and altitude..
I thought some pictures of the tuning screen would be helpful to those of you who have some interest but still have not got your minds around it... so here you go.


This is the primary screen. The gauges are configurable you can have intake air temp, throttle position, IAC position etc.. just about anything the ecm has data for can be put on the gauge cluster...






and from the tabs you can drop down the Spark Table. Keep in mind that any cell on this table can be changed to what you want and the table values are programmable as well... if you want the timing to advance quickly then plateau at a certain rpm just plug in the numbers!
I ran it pretty advanced for a while then gradually shifted the whole table to retard it untill the occasional rattle ping went away... stout!






The Air Fuel Ratio table is where you plug in your target numbers when you are running a wide band O2 sensor. The auto tune part of the software will continue to slowly tune the AFR untill your targets are reached... A 13/1 ratio is considered max torque and 12.5/1 is considered max HP while a 16.5/1 will give you great fuel economy. Just don't go too lean under load cause you will melt pistons!!






The Volumetric Efficiency table or VE table is the actual pulsewidth for the injector... higher number means longer electric pulse to the injector which equals more fuel shot in the cylinder. These are the numbers that the auto tune changes to lean or rich the air fuel ratio to meet your targets.




My setup has the barometric correction activated where it compensates for the altitude... very helpful when you drive from West Texas to Colorado to run the trails like we did this summer. Every time you turn the key on it senses tha altitude and resets plus with the wideband o2 sensor and autotune its always correcting on the backside as well.
You can also fine tune the accelleration enrichments to take all throttle lag out which you can't do with a stock setup!
I think its cool that you can build a tune to do what the factory ecm won't do which is maximize power and efficiency on any engine at any rpm or load.

This project has been fun and I am still tuning to increase efficiency. Last trip to Big Bend we got 16 mpg running 75 miles per hour with suitcases and gear on the highway and well over 20 mpg when I ran the slower runs.
