well finally going to sit down and make the build tread

It named "Sleepy" cause all of the hours of sleep I have given to this build.

So pick up this 1989 4runner fully optioned all power just no altimeter, not bad milage at 184k. It had all the records and docs and owned by a former Toyota dealer mechanic. He was up front about the suspension needing work and some rust spots, but said everything was sound.

Here is where it gets interesting, deal struck. Thought I was walking a way happy. Go to DMV and hit with 500 in back fees, Then the smog that was suppose to be done was not. Even worse when I took it to smog myself, it failed. Come to find out the head gasket was in need of replacement, even though the records shown it was done recently, had me wondering if PO was a salesman and I been had.

As it turns out, the head gaskets on the 3.0 V6 is a pain to redo, every shop and even a buddy of mines just said it was cheaper to get a rebuild and swap it.

but as luck would have it after weighing my options and looking at other's builds, I figured a swap is going to be a swap and it would be cheaper cause this came along

Tear down of 3.0 V6.. go bye bye.



The Great RMA of yotatech Fame helping me with the tear down



Ended with this

while the engine bay was open it was a good time to upgrade the brakes. New master cylinder Bigger bore dual diaphragm style



Made space in the engine bay by converting the parking brake



Opened up the back of firewall and transmission tunnel by gently massaging it with a BFH



Freshened up the suspension with OME and all new joints and rods

body lift 1" for clearance and made the lift pucks



Installed with upgraded Grade 12.9 Stainless steel hardware



built hybrid motor mounts using the factory base to keep isolators and box beams to plate for semi solid style. Made it to access bolts for easy removal.

So to keep everything California Legal and Certified had to go find the charcoal canister. Dealership wanted 1K+. This little canister had to match the engine and ecu being the donor motor was a 1995 with OBDII. what a pain



also to keep it smog legal it needed the complete oem exhaust manifold and oem catalytic convertors from an OBDII. So to fit the exhaust manifolds, the 2uz 1995 tundra log style was used, mated them to the Lexus 1uz catalytic convertors.



had to add the EBR port to keep it all legal





Bam all buttoned up and stock legal like, also the routing was turned in a little to clear the transmission and tunnel.

swapped out the LS400 oil filter mount to a new SC400 version to gain clearance



Plugged to OEM 4runner battery tray to make space for the 1UZ air box and map sensor



So to keep the A/C and power steering the pulleys were swapped on 1UZ units and 4runner. that way i could use most of the original 4runner A/C hoses



but to do that custom brackets for bot the A/C and power steering had to be made. cut apart a 4runner A/C bracket and welded mounts to the 1UZ motor.

All buttoned up and tested the belt.



So this was the gap or clearance use. not exactly what a shop would use but hell it was 1" and it gave some play and flex for moving the motor.





motor is in, kept the cruise control in hopes to get it working later.

So Transmission time, to pass California smog laws the swap has to use oem equipment. The 1UZ USDM never came in a 5sp so the automatic transmission had to be used. A SC400 transmission was selected because of the very so slight gear ratio profile. So to convert the SC400 auto transmission to 4 wheel drive there was an oem option or the 1k inchworm pre runner adaptor option. Since the cost was a factor and there was no guarantee to pass California smog, the oem or low buck option was used. Found a T100 3.4 v6 passenger side drop transfer case and tail housing, mated it to the SC400 transmission. The A340 transmission was used in just about everything Toyota made that time period but there was still some provisions that needed to be made

Tapped the SC400 transmission for the T100 tail housing



modified the output shaft for magnetic speed sensor and to fit the T100 transfer case



Freshened up the transmission and cleaned everything up after modifying the output shaft



Got excited and did an OEM transmission pan swap. The T100 3.4 transmission pan had more volume than the SC400 one so swapped them, also notice its high clearance on the passenger side to clear the drive shaft. Only time will tell if it works. kept the SC400 pan incase.



SC400 transmission pan


SC400 Transmission with T100 3.4L oil pan


modified the T100 Tail housing for the oem 1UZ magnetic speed sensor



Freshened up everything and mounted tail housing



Freshened up the transfer case and mounted the speed sensor. was afraid of leaks so extra silicone. also new seals. added a bracket for good measure

alright the transmission all freshened up and put together. Pretty much all OEM parts and all plugs checked.



Freshened up the torque convertor and don't know why there was so much royal purple used.



Ready to go in



All in and clearances checked




Bonus using the transmission pan from the T100 3.4 v6 was that transmission pan had provision for the front drive shaft being passenger drop transfer case

moved to some wiring to make sure the motor fires and runs before tackling other things like drive shafts and shift linkages and building a transfer case mount.

Wiring is ooh so fun and ....



out with the 4runner cluster



in with a Modified lexus SC400 cluster for all the modern convinces



also the Lexus cluster needed way more space to fit and space for all the extra wiring.

So had to hunt down some parts, the 1UZ was mostly complete but some parts were parted prior to getting it. Needed to find the correct Mass airflow sensor, correct set of ignitors, air box and coil for the motor. learning experience make sure all the smog legal stuff is there.....

notice the cut wires for the MAF. on a good note the fuel lines routed and should be easy hooked up with the rite fittings.

Wow, badass thread! Keep it up!

Killer build man!

looks good man
