Okay the long story short my 4runner just did the 250000 mile thing (3.0 and all!) and it still has some balls (jet computer chip, headers), and I am done replacing IFS parts.

So the truck is getting a total redo (solid axle, 3.4) the first thing I am doing is a solid axle swap which I will take pics and post up her (I know been there done that) I have a few things many people doing Toyota solid axle swaps fail to do correctly with the frame sleeves that I will point out (this leads to terrible spring flex when done improperly) it has top do with the spacers in the frame not being squared to the frame and the correct distance apart from one another.

I will post up pics of it before and after this swap, I will be doing the front 4" leaf springs as well as 80 series rear coils being added for 4" in the rear.

it currently has a Downey/Rancho Hybrid IFS kit mainly for high travel (13"), I have beat the snot out of this truck for years and the only complaint I have is the first generation downey shafts (telescoping front shafts) busted- but they upgraded and as each side broke I purchased the upgraded shafts. then the inner U-joint broke while pulling my 80 series onto a trailer with the ft wheels turned to sharp *POP* so that was the final straw. .
I have a few solid axles sitting around so it was time to do some upgrades.

I will be adding an air locker to the front diff in an 80 high pinion third member , in the back I already have a detroit locker.

things that I will have to address other than a solid axle swap I will make note of as I go (exhaust has to be rerouted from the previous 2.5 inch crossover, new fornt high travel driveshaft- etc.)

last but not least will be the 3.4 with offroad solutions adapter parts. this will be the end of the build (much later on) the solid axle first (I am working on an 80 series right now with a V8 so I dont have much time to do another engine @ the moment)

The solid axle will be a quick 1st part of this build (I already have the frame drilled/shackle pivotsin and the front hanger ready to weld on)

I hope when all said an done I can coax another 250000 out of it.
 
I like how your going with a solid axle. The IFS is just to complicated for me. I am partially redoing my front end at this time. Still unable to get ball joints out, but making progress with other things.:beer:
 
so this is done now isn't it ;) sounds cool man. I am very interested in the placement problems that you have talked about. I am in the process of going sas on my 86.
 
Here is the SAS recipient....... I am scraping the plans to do a 3.4 liter. instead I am doing a 4.0 liter Lexus V8(1UZFE) , that is more up my alley.
these engines are just as available as the 3.4 and beleive it or not cheaper in most cases and much more cheaper that the slavage yard replacement 3.0
I will retain an automatic with this swap.

250 HP and 260 ftlbs of torque. a very resposive engine to modifications. I figured if I were to do a 3.4, I would always wish I had done the V8 instead.

I will need to use a T100 auto behind the Lexus V8 (it bolts up to the V8 bellhousing) along with a JPeater brand Gear driven Tcase adapter to make it work. I figure a bit of wiring and a signal convertor (Tach) along with modified engine mounts (IE new, in a different place) there is a 3rd gen 4runner being done as we speak... I will try to get him to join Mud and post his buil dup here.

I used to have a SWEET 1st generation 4runner and some dumb ass in a neon hit me pretty much head on (tore his car in half about) and mine still started and drove (not too pretty though!)
 
okay update, I just picked up a Lexus LS400........... screw the 3.4 swap- I am doing the Lexus 1uzfe into my 4runner. 245 HP with headers and piggyback computer it will be @ 300HP.

I have the motor mounts designed to make this a bolt in swap into the V6 trucks, as well as I am working on a set to bolt this engine into a 4cylinder truck/4runner also for those interested in doing this swap in V6-4Cyl. trucks/4runners.

This is a toyota engine and is in the Toyota Crown (ls400) and the Toyota Soarer (SC400) down under in Aus.
The Lexus "L" and the name "Lexus" on the intake is an emblem only and the Toyota "T" and word "Toyota" fit in the same place from the Aussie engines, so I will order a set to "authenticate";) the engine.

I will be using an A340F transmission out of a Tundra , along with the Lexus front pump, and a modified Valve body. I will add the transfer case by bolting up a gear driven Transfer case adapter from Jack Obrien @ 4WHEEL west and a JP eater brand dual tranfer case adapters to add duals to the mix while I am in there.

the LS400 is getting chopped up and parted out as we speak, so by doing this I hope to offset my costs of the car and adapters needed for the drivetrain, I hope to break even when all is said and done.

I will need to fab up headers for this since no one makes them, the wiring is almost identical to my Tundra 2UZFE that I am dropping into one of my 80 series so I am ahead of the game there. I want to acquire all parts needed and do this in a period of about 1 week.

so now off to get a low mileage A340F a few adapters and some prebent header tubing.:bounce:

HUH? The T100 auto is no different than yours. Both are A340 series autos with the same bellhousing. The T100 came with the F series, which is waht is behind all 3.4's, which can bolt straight up to a 3.0. You can use your existing a340H with a Gearslug or Inchworm adapter to a gear driven tcase.

I updated in last post, I am using the a340F out of a Tundra/Tacoma. the a343 wont work as it has 3 solenoids- the later A340F/E is compatible with the Lexus computer as it only has 2 solenoids to control like the lexus computer is set up to do.

I am using the toughest gear driven tranfer case adapter available, the JP eater by 4Wheel west along with their dual tranfer case adapter-
I have a 4.0 V8 from a 2001 lexus (VVTi) that I am building to about 400-425hp NA that will replace this one in about 12 months, so anything behind it needs to be as strong as it can be (IE Valve body, adapters)
