So, this build thread is an attempt to provide facts and advice for others who may do this swap in the future. Lots of research, time, and money are required for a swap. Below is my contribution.

1987 4runner sr5 5spd
1" body lift
R150F transmission

Donor Car:
1991 Lexus LS400 98k miles. The 1UZ came in multiple cars, with 3 different types of oil pan sumps. The LS400 has a front sump pan which is needed to for an IFS truck. The SC400 has a rear sump which is needed for a Solid Axle Truck. The 1uz changed in 98 to include toyota's VVTI technology. That technology produces more HP but has security called an immobilizer built into the vehicle that makes swapping it very very difficult. I opted for a pre 98. The early 1uz such as mine has the beefy rods capable of handling plenty of power so I was ok with the possibilities.

What is the limiting factor that makes a minimum of a 1" body lift mandatory?

Parts List:

-Engine pre 1995 1uz for strongest rods
-AEM Infinity EMS
-Timing change Kit
-COP conversion to eliminate dissys, coils, etc.
-1uz Fuel Pump (I believe 225lph capacity. Can't use 4runner, too small)
-Tundra 2uz headers (Best headers for 4runner clearance. Minor Modification)
Wiring Harness Conversion (The nitty gritty. I had yotatech member 'RMA' do mine. After doing 3 already, he was well equiped and was able to include the proper connectors for the adaptation of the sc400 harness. Since I had an ls400
wiring harness, I needed the sc400 connectors to the cluster, as the ls400 connectors are not the same.)
-Motor Mounts (pre fabbed available from Gloverman on Lextreme.com. He also sells them on trademe.co.nz I had mine
made.)
-315cc Injectors (may run higher since I'm running aftermarket ECU now)
-Denso IK24 Spark Plugs
-SC400 Cluster (using in lieu of factory cluster)
-Oil Filter relocation Kit (sc400 filter setup will work, LS400 will not. I chose
remote relocation)
-Adapters (R Series bellhousing to engine adapter)
-Flywheel (There are no factory made 1uz flywheels. Must either modify the 4runner flywheel with new boltpattern, or
buy one custom made which is what I did)
-Clutch (uses the actual clutch for your transmission. I went with a competition clutch stage 2 non ceramic)
-Alternator (145amp upgrade is a good thing to do and is what I did)
-Power Steering Pump
-Electric Fans (depending on your clearance which depends on how far back you get the motor, 2 or 3 electric fans
will -work. I will run 3, 10" 900cfm fans. These fans should be pullers and not pushers for proper cooling.)
-Heads ported
-Kelford 207-SC Supercharger profile Cams (higher exhaust lift and less intake lift to get the gases out)
-Lextreme Valve Springs
-Labor (I paid someobody with the experience, talent, and uncanny ability to do swaps.)

Supercharger
-Lower Manifold fabrication with waterbridge and fuel rails
-Eaton M112 Supercharger Ported
-Ford Cobra Throttle Body (since I'm running the aftermarket ecu I can do this)
-AEM Water Methanol Kit
-3" pulley
-TRD Boost Gauge
-Labor (fabricationg the supercharger, porting it, and installing it)

Interior
-New Carpet Replacement
-FatMat Sound Deadning entire cab
-New Gray Shift Boot
-New Center Console Lid
-Grant Steering Wheel
-Tacoma Gray Shift Knobs
-Lexus LX400 Rearview mirror with autodimming, temp, compass, homelink
-4th Gen 4Runner Sun Shades

Exterior
-Door Seals Replaced
-Body Restoration and trim out for new color
-ARB front bumper
-Marlin Crawler Rear bumper
-Non sealed headlight upgrade

Suspension
-ProComp Wheels
-MT 33" tires
-Sky offroad SAS Kit (Spring under for less lift)
-Man-A-Fre U-Bolt flip kit (for spring under kit)
-Man-A-Fre Tie Rods
-Marlin Crawler Billet Steering Arms
-Bilstein 5150 rear shocks
-Rear Wheel Bearing Replacements
-Front Axle rebuild and wheel bearing replacement
-Redline MT-90 75W90 Fluid for everywhere

Here are the pieces for the motor mounts. Once you determine the exact resting place of the engine, the mounts will be completed.

The Cluster modification requires fabrication. I had yotatech member 'RMA' do mine, as he is the only person that I know of to have actually done this to others. He made a backplate to accept the new SC400 board, and attached connectors to bolt it down in the back. It really is amazing and clean. he even used a pre 84 truck with no tripometer hole to cover it. Tinted just like the factory sc400, this is what it looks like when finished. (Picture of a vehicle RMA did, not mine)

You can't mount the engine low enough in the engine bay without a body lift. RMA has completed 3 so far. He made a custom 'frankenpan' specifically to get the engine low enough without a body lift, and in the end, had to do a 1". I have found no example of a 1st gen 4runner without a body lift, and a 1uz swap.

is your swap being done in raleigh? I am a few hours away and would love to do this.. what do you think your end cost will be?

Durham, although I do live in Raleigh.

If you are not doing any of the work yourself it cost a lot more. I am having everything "contracted" out so that it is hassle free for me. Labor for these swaps can be 2-4k depending. Parts, depending if you're doing it right, or taking shortcuts, another $3k.

Before I dropped the truck off for the swap, I removed the interior, put fatmat sound deadoning material down, and replaced the carpet. The fatmat is awesome and will allow me to be able to peacefully ride in my 4runner while not being pestered with road noise. The picture is during the laying of the trunk. (and before my upgrade from droid eris to droid razr camera #crappyphoto)

Will need this for later!

Keep this post full of pics and that advice you offered. I'm about to start gathering parts and research to do this swap in an 87 4runner with straight axle swap and I was going to look for a vvti motor till I saw your comment about the immobilizer. Might have saved me from a costly mistake. thanks.

No problem! The 98+ vvti engines are going to be a huge huge headache, both now and in the future, I would suggest steering away from that. Remember, straight axle requires the oil pan from an SC400 to work. If you get an Ls400 motor, you can go to lextreme.com and find a ton of people wanting to swap their sc400 pans for ls400 pans so don't worry about specifically having to buy the sc400 engine.

I had to change clutch orders due to competition clutch being out of pressure plates at the moment. I went with the Centerforce DF501110 which states up to 90% more holding power. Probably a good thing, as it needs to be much better than the oem. If you do a swap, do not put an oem 4runner clutch back in. Even the 3.0 which is what I have, isn't strong enough. I have read no less than 2000lb of clamping force.

That's pretty epic. I live in Fayetteville and would like to come take a look at your rig one day.

Any updates?
