Love my swap! Added electric fans to it and now when im on the highway i dont feel it drag when that fan clutch locks.

So i still dont have a speedo in my truck and i was looking in tot he marlin adapter but i was told it goes on the end of the cable. I really want a VSS in the Tcase. Is it true about the marlin part being a piece that goes in the cable?

I have a friend hooking up a VSS and pig tails but it doesn't work all the time. Anyone have an exact year VSS to get to put in my topshift tcase and wire up to a 00 ECU? My buddy works at a parts store.

i need some help trying to find the wires for the o2 sensors, mainly just the 1st sensor. i cut 95% of the original harness so i have no idea where the original come from. if anyone could trace the o2 wires and tell me where they go into the harness that would help a little. i have a 99 2rz.

here is what i used to wire my engine up, im having trouble figuring out wich wire need what power or ground so if i have to i could wire the sensor straight from the computer.

I believe the rear connector and wire drop out of the bottom of the cab and is connected to the in-cab harness somehow.

steve_925- my harness was out of an 01 3rz automatic so i dont know how different they are but on mine the wires for the first sensor drop out with the rest that go to the tranny. they come out of the main harness at the back of the intake and the colors are ;white,pink,purple and white red.

i think im gonna have to just run new wire straight from the ecu

On my 98 Tacoma 3RZ engine the front sensor wires are
White/Red - 12V For Heater
Brown - Ground
Red/Black -Computer grounded for heater
White - Signal to computer

The rear sensor wires are
White/Red - 12V For Heater
Brown - Ground
Red/White -Computer grounded for heater
Black - Signal to computer

Both those sensors come out of the same harness, the one that is located behind the valve cover. It looks like if you have to run all new wires, you can run the two 12V White/Red and Brown ground wires in parallel. Then all you would really need to run are the computer switched grounds and computer signal wires.

Here is a link to getting all your smog readiness monitors to run once you have completed your swap. It details the drive patterns and conditions that have to be met in order to have your EGR, EVAP, 02 sensors, etc to start working. Very useful if you live in CA and you have to have all your monitors running in order to pass the referee.

Someone REALLY needs to bring a conversion harness to maket again now that ORS is gone. These swaps have so much to offer, but some of us are not vey electrically inclined (aka... me).

Engine mounts seems to be easy, especially the ones that were made for Bevin's conversion.
The Transmission conversion bellhousing is convered by marlin.
The exhaust can be done by a local exhaust shop.
EFI tanks and fuel pumps are pretty common and inexpensive.
The oil pan poses an issue with stock height IFS, but it can be it can be modified to work.

Its just the wiring that scares me.

Hey does anyone have any info on swapping a 97 taco dash into a first gen 4runner??I have heard that the entire dash fits with little modification, and simplifies the 3rz swap wiring.

Im working with Mike the former owner to offer one. Sometime soon I'll have more info for you.

I started with the A-pillar dash cross bar, and used the AC,Blower and heat boxes all from the Tacoma.

I have a couple of questions

1. does anyone know if a w56 clutch fork from a 22re will work with the w59 bellhousing?

2. I live in a smog exempt county, if I wire my 03 3rz without ANY smog equipment (evap canister, egr, etc) will it still run right?

3. Do I HAVE to run cats?

I want everything to be as simple as possible. I dont care if I have a check engine light on, as long as it runs 100%. Im new to obd 2, and not really sure what makes these go into a "limp mode." Thanks in advance

TacoRunner · « **Reply #583 on:** Jan 05, 2011, 08:56:26 AM »

Clutch fork, oh crud, let me think about this. I "think" you need the w59.

As for everything else, I have no experience with those items.

BUDDERS · « **Reply #584 on:** Jan 05, 2011, 12:19:53 PM »

I used the w56 clutch fork with my 3rz swap - the biggest issue is the throughout bearing when going this route. I think the bearing I used was from a 3rd gen pickup but can't remember for sure. I just know that the one that came with my w56 wouldn't work - I think it was too short and the w59 bearing from a tacoma had too big of a center bore - it looked about 3mm too big.

My clutch grabs as soon as I let the peddle off the floor (and I've adjusted it to do the opposite) so I think when it comes time to pull the trans, I will replace the clutch fork with a w59 setup.

i had the same issue, but i just made a longer push rod for the slave cylinder

Hmm... that sounds easy enough. I wish I still had access to a lathe though.

its way simplier than that, just take a 12mm yota bolt that is 1/2" longer than the stock slave rod and round the ends off with a grinder.

That sounds easy enough. I have a couple old slave cylinders lying around now that I think of it - I might see if any of the pushrods in them are any longer than the one in my truck.

great information everyone.

I only saw 2 post on gas mileage, and one was around 19, the other said over 20.
I am guessing that gas mileage with the 3RZ is about the same a a 22RE, but with more power???

TacoRunner · « **Reply #590 on:** Jan 21, 2011, 08:23:29 AM »

Depends on gearing and tires but I've got 37"s and 5.29s, I get 17 on the freeway driving from LA to Fresno. Street is like 12. But if I go back down to 35"s and 5.29s, because the speedo is then inaccurate, then it says Im getting 23. Which is not right at all.

From bigmike:
You will have to change the ECU to a 5spd ECU as I was unsuccessful at fooling the Lock-out Torque convertor circuit and the three shift solenoids (A, B, and C) circuits from the Automatic ECUs.

Making the auto ecu think its in park should allow the engine to turn over/run. What are the issues with mike's statement above? Just throw a check engine light?

I'm almost done with my swap and should be firing it up this weekend...just need to know if I need a manual ecu by then, or if I can wait until I'm ready to go through the BAR.
Thanks.

85yotabox · « **Reply #592 on:** Feb 23, 2011, 11:34:43 AM »

The auto ecu works and runs fine it just throws on the check engine light. With the manuel ecu u will also need to hook up the speed sensor to your tcase otherwise it will throw a code too.

smacaulay · « **Reply #593 on:** Feb 23, 2011, 12:28:27 PM »

Good to know, thanks for the info 85yotabox.

I picked up the marlin vss to hook up the speedo...I swapped over the full interior w/ 3rz gauge cluster. Getting the speedo to work seems fairly straight forward.

85yotabox · « **Reply #594 on:** Feb 23, 2011, 08:53:39 PM »

Nice! Thats exactly what i did, used the whole 3rz harness inside and out and just plugged in the gauge cluster and it actually fits really well in my second gen dash.

BeerHat · « **Reply #595 on:** Feb 24, 2011, 09:19:46 AM »

Does it matter which manual 4x4 ecm you use provided that it is the same year of the engine? I got a 1999 3rz but has an auto ecm. According to ToyoDIY, there are 3 different ecm part numbers for the manual 4x4.

EDIT: found this thread that allows you to trick the solenoids and park/neutral on the Auto ECM and without throwing the check engine light. So, tech. you can use the Auto ECM without issues.

There are three different versions if I'm not mistaken:
Distributer
Twin coil
Quad coil

I think the 99 is a twin coil setup, same as my 97. If ur using the same year ur probably safe.

Does the ecu have to be the same year as the motor to pass CA BAR? Does the ref check the ecu?

Hey I have a question, I am in the process of putting a 3rz in a 95 4runner. I want to do hydro assist, am I going to have to get a different power steering pump? Or is their a mod to make this one work?

I ran hydro assist with the stock 3rz pump and it was toast after the first run, and it also could not keep up with the ram as well as an after market one can. I got the psc pump and resivour the recomended for the ram i have and it works great.

Wish I knew how to post pics, might help explain my questions...

Looking from the front of the truck, the top of the intake plenum (facing forward) has a circle with two vacuum hoses coming off of it (top and bottom left side of circle)...right next to the OBDII port. The top one I have figured out, but the botton vacuum line I have no idea where to hook it up to. Any ideas?? I have seem some swaps with a bolt in this location, others with a vacuum line running from it. The motor is a 97 dual coil 3rz if it matters.

Also, the vapor line running from the fuel tank (pretty sure that's what it is) gets run to the evap box? Anyone have a pic, or can describe which location to hook this up?

Thanks.
