Wiring and Electronics / Phoenix Tuning, first impressions
« on: February 03, 2009, 01:06:42 AM »
A few months ago, I decided to skip the headache of trying to figure out the wiring aspect of my swap and use the folks over at Phoenix Tuning to do it for me.  They were a little pricey, but I figured it was worth it in the long run.

After waiting a little longer that I originally expected, my harness showed up!  I pulled it out of the box and looked it over.  It

Hey guys,

Radiators, Fans and Cooling / Overall Dimensions of Lexus Radiators
« on: December 07, 2008, 02:30:21 AM »
Ok guys, I wanted to start a thread where folks could post up the overall measurements of their Lexus radiators.  Since space is so limited with these swaps, I wanted to be absolutely certain a radiator would fit before buying it!

All of the info I

For Sale / Rear-sump oil pan
« on: November 04, 2008, 11:48:15 AM »
Have a complete rear-sump setup from a '97 SC400.  Includes both halves of the oil pan, dipstick, and oil pump pickup.  Only problem is that the threads on the lower pan got a little munched and you might need to re-tap it with a bigger oil plug.

$50 plus shipping (from 87120) sound fair?

Wanted to Buy / Parts needed!!!
« on: August 13, 2008, 11:22:10 PM »

I'm looking for the following parts.  They're for a 3rd Gen 4Runner (96-02)...
-Output flange for transfer case
-Speed sensor for transfer case (I believe these were found on non-ABS 4Runners/Tacomas)
-Shifter lever (J-style, not 2-4 selector) for transfer case
-Rear drive shaft

Anyone have any of these parts for sale?

Mating an Automatic Tranmission / Lexus A340E to 4WD?
« on: July 27, 2008, 11:58:10 PM »
Ok, I'm trying to tackle yet another aspect of my 1UZ swap...
In addition to the installing the motor, I decided that I should complete my 4WD conversion at the same time.  Or at the very least, install just the front differential so that when I place the 1UZ into the engine bay, the position is correct for when I complete the 4WD conversion later down the road.

Anyway, I had some questions regarding the transmission and transfercase.  I was planning on using the Lexus 340E transmission for the same reasons Cebby wanted to - primarily to make sure the tranny and ECU would "talk" to each other.  I'd decided the best way to accomplish this is to use Inchworm's Pre-Runner adapter.  But I remembered reading that adapter was designed for RH-drop gear driven cases.  And after speaking with Jim, he confirmed it.  So for my 3rd Gen 4Runner, I'd have to additionally buy their "Lefty" transfer case...a bargain at $2000!!!  Needless to say, I don't know if I want to spend that much.  I asked about using a stock, LH-drop chain drive case but was told that that setup wouldn't work since there are no provisions to mount the transfer case to the transmission cross-beam.

So here are my questions...

From what I've read, it seems the biggest issue of trying to simply remove the 2WD tailhousing from the Lexus tranny, bolting on a 4WD tailhousing, and then connecting a stock transfercase would be the Lexus output shaft being too short, right?  But after looking at the following photos, it seems like the shaft might be long enough.  I long is a 4WD tailhousing?

(borrowed this from SAR Squid on TTORA)  Picture of a Tacoma 2WD tranny with tailhousing removed...Lexus tranny is same length output shaft.  Would have to cut off the threading, but still looks like the output shaft would go into the 4WD tailhousing a good several inches...

Photo of a transfercase from a 97 4Runner Limited.  Looks like the input coupler would go into the 4WD tailhousing by a few inches...

So what am I missing here?  How far does the tranny output shaft normally go into the transfercase?  If I do need a longer output shaft, do you guys think this would work...
-Measure how long a shaft is needed to properly connect transfercase to tranny
-Get a 23-spline shaft and a coupler
-Cut shaft to correct length
-Slide coupler over end of Lexus output shaft
-Insert splined shaft into coupler and other end into transfercase

Voila?  Or am I missing something else?

Also, in the photo of the transfercase above, is that strictly a "mechanical" case?  Meaning no shift-on-the-fly, ADD, etc?  I compared it to the photo Cebby has of the case attached to his '00 A340F.  That one seems much longer & complex than this one.  This case however is apparently from a 99 4Runner SR5 which I thought for sure had ADD, etc.  Any insight?

Wiring and Electronics / 1997 SC400 Wiring Harness
« on: July 22, 2008, 02:08:45 AM »
I've finally finished putting my 1UZ back together and now in the process of labeling all the wiring.  I've read through the wiring schematics a bunch of times, but I need to start with a big picture first!

Here are a few photos of the engine loom, coming off the left side of the engine.  Anyone know what these connected to in the Lexus?  Did they plug into the fuse block?

***Update***  Ok, I've figured out two of the six connections.  #2 goes to Igniter 2 and #3 goes to Igniter 1.
                          Any ideas on #1, 4, 5, 6?

***Update***  I was told that two of these six connections would go to the fuse box in the SC400...

This is the Alternator wire, on the right side of the motor.  The two black connections go to the alternator, but where does the other end connect to? (the grey & pink ones)

Lastly, does this wire simply ground to the body?

Vendor Feedback / Irbis Offroad - Denver, CO
« on: March 05, 2008, 11:18:28 PM »
I finally made it up to Denver this past weekend and was able to stop by Irbis Offroad (  I visited with Yuri and Oleg and have to say these guys are great!  They have a yard filled with 4Runners & Land Cruisers, ready to be parted out.  I ended up getting some FJ80 parts for my UZ swap and was very pleased.  If you're in the area and need some parts or just want to see a true "mom & pop" offroad business, I highly reccomend them!

Transfer Cases / Tranny/Transfercase Issue in 91 FJ80 1UZ swap
« on: February 14, 2008, 01:11:13 AM »
Ok, I’ve reached a major hurdle and need some advice.  Since deciding to swap the 1UZ into my ‘91 FJ80, I have yet to figure out a tranny/drive-train solution.  Because the Land Cruiser uses an offset driveline, I need to keep the HF2A transfer case.  I’ve called Advanced Adapters, Marlin, Inchworm, etc. and no one makes anything to mount this TC to a 340E/F transmission. 

This fella ( had a custom adapter made to bolt up a Range Rover LT230 case to a 340E, which seems like a decent option, but I’d like to keep this all Toyota if possible.  So here’re the options I’ve come up with so far…

1.  Use the tranny from the SC400.  Have an adapter custom made.
   PROS:  Using original A340E eliminates ECU-to-tranny miscommunication.
   CONS:  Probable high cost of a custom adapter.  Plus, where to have it done?

2.  Same as above, but use LT230 transfer case.

3.  Source a complete 343F transmission from a 98+ Land Cruiser that had a 2UZ.
   PROS:  The closest to a plug & play solution.
   CONS:  Cost and difficulty of finding one.  How easy/hard would it be to wire up the tranny…How similar are 343 and 340’s?  (number & function of solenoids, etc)
Oleg at Irbis Offroad suggested maybe using the 340E with a divorced transfer case.  Where the idea is a good one, I think with the fabrication involved, I’d just as well have someone fab an adapter that directly mounted the HF2A transfer case to the 340E housing.  But then again, has anyone run a divorced TC before?  Easy?  Difficult?

Like I said, I’ve hit a roadblock with this.  Anyone have suggestions/advice/comments?

Originally I was going to put the 1UZ into my 98 4Runner, but decided to swap out the tired 3FE in my '91 FJ80.  I contacted the folks at Phoenix Tuning in regards to a wire harness, and was told if I do this swap, I'd need to install a "fuel tank pressure sensor" in the Land Cruiser.  It was mentioned that I could use an ECU from an older (OBD I) 1UZ and not have to worry about it...

So the big questions are:

1)  Aside from the ECU connections being different, could I in fact use an ECU from lets say, a 93 LS400 on my 97 SC400 engine?  (In other words, how much difference is there between 95-older and 96-97 (non VVTi) engines?)

2)  Has anyone had a "fuel pressure sensor" issue with 89-95 model 1UZ's?  I'm assuming I was told it would be a problem because my 1UZ is from a 97 vehicle...

Wanted to Buy / Wanted: Bellhousing & tranny parts

Looking for a bellhousing, torque converter, input planetary, and oil pump from an A340E or A341E...

'95.5-'04 Tacomas/'96-'02 4Runners (3rd Gen) / 98 4Runner
« on: December 07, 2007, 08:47:11 PM »
Motor showed up today!  ;D ;D ;D  Didn't have my camera, so I couldn't take photos but I'm gonna try to this weekend.  Anyway, the motor is from a 97 SC400 and looks pretty clean.  I did a once over on it and noticed the only thing that was broken was the pressure sensor(?) coming off the oil filter mount.  (The front of the engine was supported on the pallet by only a 4x5" block).  Needless to say, it shifted in transit and allowed the front of the motor to impact the pallet, snapping the plastic portion of the sensor and denting the oil filter.  >:(  Oh well, let the parts list grow!  This leads me to my questions...

1.  But before I can start this project, I need to get the engine on a stand...what size are the bolts that attach the bellhousing to the block?  I'm gonna have to run to the store to buy some.  16mm?  18mm?

2.  Anyone know the part number for the starter contacts?  Would they be the same for a 2UZ?

That's all I can think of right now.  Plenty more questions to come later....

Mating an Automatic Tranmission / Using an A340E?
« on: November 16, 2007, 05:21:00 PM »
Well I finally decided to post something after months of trolling around!  Anyway, here's what I'm starting with:  98 4Runner, 2.7L, 2WD, Auto.  I've been thinking about doing this swap for a while now, but still in the process of gathering info.  I was planning on keeping my truck 2WD for now, and had some questions about using my existing A340E transmission.  I've read the 92-97 SC400 & 95-97 LS400 use the same transmission, so...

1)  As far as physical fitment, would my 340E bolt right up to a 1UZ, or are there slight differences between the Toyota & Lexus versions?

2)  Would I need the bellhousing from the Lexus?  Torque Converter?

2)  Are there any other differences that would potentially cause problems (i.e. speedos/solenoids)?
