22RE to 3RZ swap
Troy asked me why I chose the 3RZ over all the other (bigger) motors out there. I had a couple reasons. One, the 3RZ bolts up to my existing drivetrain - I don't have to fab a crossmember for a different transmission/tcase, I don't have to mess with driveshafts, I don't have to pay for aftermarket adapters, etc. Two, the 3RZ is a roughly 50% increase in power over my little 22RE without taking a mileage hit - I drive this truck a lot and I need to stay near or over 20MPG, and power for weight the 3RZ brings more to the table than any other motor I considered. Three, it fits in the engine bay with ample room around it for my thick hands, I don't need to worry about clearancing the hood or core support or putting on a body lift or anything else, I like that. Four, it's Toyota. I admit that I'm a bit of a Toyota fanboy (ok, more than a bit), but I've been lurking Toyota forums for years and even though I've never owned a 3RZ truck, I've still picked up a bit about the motor through osmosis, and it's not that far from the 22RE I'm already familiar with. There's other swaps out there that are just as well documented and just as viable, depending on your priorities - I rejected the 5VZ motor because of drivetrain concerns, I rejected the 7MGE because it's reported to have oiling issues at low RPM, I rejected the smallbock Ford and Chevy motors because I don't know them and to be honest, I'm already a bit outside my comfort zone. A Ford would kick ass, maybe I'll do that to my next truck.
Regarding legality, I don't have any hard answers yet. I spoke to a fellow at Salt Lake county, who was very friendly and willing to talk - he told me that as far as the state is concerned, as long as I pass safety they don't care. The County is who cares about emissions, and since the Bastard is pre-OBDII, all I need to make them happy is make sure I still have all the emissions from the old truck and the new motor, and then pass a tailpipe test. I think that means that as long as I retain the charcoal canister and EGR, I should be good to go (and in a couple years, I won't even need that ). Once I've ID'd exactly what year this block is (more on that later) I can call them back and we can discuss specifics, but there's no huge roadbock in my way like there would be if I was using an older motor or a diesel or something.
This swap is well documented all over the internet, so I won't be breaking any ground here. This is good, because I'd wouldn't even think about taking on a project like this if I didn't have a road map to follow. Here's some good links I've been reading:
(hmm - can't get to the Marlin Crawler boards from work. I'll add those links later.)
These guys have conversion stuff - harnesses, motor mounts, exhaust bits, etc:
What I have, right now -
Early 3RZ motor (year unknown, it's set up for a distributor, making it a '95 or '96?)
T rear sump oil pan (for axle clearance)
Tacoma bellhousing/clutch/friction plate/etc
Complete engine bay harness, most of the dash harness (some bits are cut, I haven't figured out exactly what yet. They may not matter?)
Computer (it's labeled for a '97, which is the first year of the coil packs? May not work with this setup. Research is required.)
Various other bits - manifold, motor mounts, intake and throttle body, etc)
What I know I'm missing -
Power steering pump
MAF and intake box
One fuel injector is missing (I need to call Dylan and see if that fell out in his shop)
None of the yards in town that I've called so far have a 3RZ truck that I can come pick over, so I'll have to pick this stuff up piece by piece (www.car-part.comis a good resource). There's two different starters and two different air boxes for the '97 trucks, but I may not even have a '97 here, so that's got to get figured out before I can move forward.
What I need to do -
- Get the existing 22RE out of the truck, sell it, clean up the engine bay.
- Get the 3RZ on the stand, check the bearings, see if I can hook up a starter and check the compression. If I can verify good bearings and good compression, I won't tear this motor down before I put it in. I might get lucky, we'll see.
- Figure out motor mounts. The 22RE and 3RZ motor mounts are pretty much identical. The place they bolt to the frame is different - I might move the frame mounting location, or I might hack together an offset mount like Chilkat sells. One concern is clearance between the intake plenum and the dual diaghram brake booster waiting patiently on my shelf, so I need to hang the motor in the bay and see where everything sits before I make up my mind here.
- Replace the clutch and bearings. I don't HAVE to do this, but the friction plate that came with the motor is looking thin, and it'd be a PITA to have to replace it anyway a year from now, so I need to make room in the budget for new parts here, and I need to get them on the truck.
- Install the motor to the engine bay.
- Figure out intake. The intake and exhaust are flipped from how the 22RE is set up, and I've got a battery where the 3RZ airbox wants to go. I might move the battery to the other side, but I'm more likely to build a custom intake to share the space with the battery. Might even set up a snorkel - I've never come anywhere needing one, but you never know, right? I got quoted $ for a stock 3RZ airbox (just the box!), so for that price I might as well put on a cone filter or something and call it good. They aren't my favorite, but it'd be a lot less work.
- Figure out the exhaust. I read that these motors don't respond as well as the 22RE to just an aftermarket header, and I don't have the bucks to do any other upgrades to go with it, so I'll probably skip that for now. I have the stock manifold - I'll probably just use that and have a muffler shop build a crossover to my existing cat and add the necessary O2 bungs. I need to verify with the County if my stock cat will pass or if I need to use a cat designed for the 3RZ.
- Hook up fuel, clutch, steering, etc. I read that the fittings on the fuel line and high pressure PS hose are the same, so some extension or trimming will be necessary, but I shouldn't have to chase down any parts. The clutch line needs moved, and I might get away with using the 22RE clutch slave upside down? I havent looked closely. At worst, I'll need a new clutch slave and shift fork.
- Figure out wiring. Everything else is just turning bolts, and I can handle that. Wiring is the part that scares me. The guy I bought the motor from offered to help, and I have a mechanic friend willing to pitch in as well. If all else fails, I can buy an aftermarket conversion harness for around $, but that's a lot of money I don't have so I'd rather not if I don't have to.
- Start the truck.
- Go wheeling.
Budget - right now I've spent $ This number will go up . I budgeted $ for the whole deal, and I can already see where I'm going to blow right past that and land closer to $ if I don't find some deals on parts.
So that's where I'm at. My deadline is mid-April there's a Moab trip on the books that I don't want to miss, and there's a boy due in May that'll take a huge slice out of my free time, so I need to get my butt in gear. I'll update this post as I run into stuff I need that I don't have, and as I get stuff done. I'll probably take some pics along the way, but probably not a lot. Feel free to give me advice or tell me I'm doing it wrong or whatever.
I'm looking for another engine hoist, if anybody has one they're willing to sell (or loan indefinitely). The one I'm currently borrowing needs to go home, and everything for sale on KSL is outside the budget.

ORS 3RZ-FE / 2RZ-FE Conversion Wiring Harness
The 3RZ-FE / 2RZ-FE (L or L) fuel injection system is entirely different from that of the older Toyotas. This means the 3RZ electronics and circuit will have to be installed in your older vehicle in order to make this engine swap possible. The Off Road Solutions 2RZ/3RZ Conversion Wiring Harness will provide the donor vehicle engine and transmission control circuits in your older vehicle for use with the Toyota engine 3RZ/2RZ computer and components.
Please not that this product is for both the 3RZ-FE and 2RZ-FE engine swap. We will continue our description using the term 3RZ for simplicity.
From the factory, there are 2 primary parts of the OEM 3RZ fuel injection wiring circuit. The first is the engine wiring harness. This is the harness that is primarily attached to the engine. This is sometimes called the injector harness. This harness connects the engine components such as the fuel injectors, ignition coils, air flow meter, etc. to the engine computer (ECU) and the body harness.
The second part of the 3RZ electronic fuel injection circuit is built into the body wiring, along with the rest of the vehicle’s circuits. The body wiring includes the under-dash harness, the engine-bay harness (including fuse box), and even the wiring to the rear. About 40% of the 3RZ fuel injection’s wiring circuit is contained in this harness.
We offer our 3RZ Conversion wiring in 2 main formats:
- Our 3RZ Conversion Adapter Harness is designed for applications that have a used, good-condition, intact engine wire harness from the donor vehicle. Our Conversion Adapter Harness will connect directly to the engine wire harness and the ECU, and works along with the donor engine wire harness to fully complete the engine wiring circuit. Note: The Adapter Format of our conversion harness will not work with “JDM” engine wiring (from Japanese Domestic Market); our Engine wiring format is recommended with JDM donor engines. Once again, the Adapter version requires the use of donor engine wiring that is intact and in good condition; from a North-American-based donor vehicle.
- Our 3RZ Conversion Engine Wire Harness completely replaces the engine wire harness while also providing the portion of donor engine circuit originally in the body wiring. This harness is a combination of an engine wire harness and an adapter harness and houses % of the 3RZ engine circuit in one all-new piece. It is intended for situations when the donor engine wiring is missing, cut or in poor condition. It also works well for JDM import engines since the JDM engine wiring is hard to use in a LHD application.
We also accommodate 2 main recipient vehicle types:
- Our 22R-E/3VZ-E Vehicle option is for ’’95 Truck/4Runner and ’’94 T vehicles that originally had the L 3VZ-E engine or the fuel injected 22R-E. This version requires that the original body wiring and fuse box is still in place and will plug directly into the body wiring for a simple install. Very little splicing is required to install this version, it is nearly % plug-and-play. The original wiring in your older Toyota will not have to be torn apart, and this version will accommodate your OEM gauges (tachometer will require some additional work during the install), speed sensor, reverse lights, 44 system and 44 indicator lamp.
- Our Stand-Alone version is designed for virtually any other vehicle. It works well with carbureted vehicles, other makes, and some race/custom vehicles. This version requires that the vehicle has at least a basic electrical system already in place. This basic system must include: start and ignition switch, charging, fuse/battery and gauge circuits. This will connect to the recipient vehicle through a few simple splices. Note that the Stand-Alone version includes a fuel pump power/control circuit. Note: if your vehicle has no wiring body wiring at all see our Monster Harness.
We offer 2 options regarding the transmission:
- Manual Transmission: Use this option when using a manual transmission. This includes a case where the donor or recipient vehicle was originally auto and the engine setup will now be manual.
- Automatic Transmission: Use this option when using a Toyota automatic transmission. This includes a case where the recipient was originally manual but is now being converted to an automatic transmission. Like the engine circuit, the transmission control circuit was originally split between the body and engine wiring. The Adapter format will include the portion of the transmission control circuit originally placed in the body wiring and the Engine Wire Harness format will include all-new transmission connections.
Donor vehicle pricing options are for the Adapter format and depend on the engine harness donor application.
This product is built per order, please allow weeks for order completion. This time can vary by season, if completion time is crucial, please contact ORS before ordering.
Notice when ordering: Please include the following information in the “Order Notes” box or a separate email when placing your order. If sending a separate email be sure the name on the order will be obvious.
From Donor Vehicle:
- VIN, only if % certain of engine origin, OR part numbers requested below
- Toyota ECU part number (x-xxxxx)
- For Adapter Harness version: Toyota engine harness part number (xxxxx), this is found on a paper tag near the ECU connections.
- Model Year
- 4WD or 2WD
- Manual or Automatic Transmission
From Your Vehicle:
- For 3VZ-E/22R-E type: VIN
- Year Model
- Original Engine
- Manual or Automatic Transmission (originally)
- Indicate specific transmission to be used in conversion
- 4WD or 2WD
- If 44, indicate transfer case application, original to transmission or changed
- Front suspension type (original or modified)
- For Truck, 4Runner, Indicate if ADD (Auto-Hub) system is in use
- Swapped battery location
- OEM (original-type) tachometer in use?
Core Connectors for 22R-E/3VZ-E recipient type:
For some applications we will need a core connector from your vehicle. If your vehicle is an ’’90, we need one core connector. It is found on the 22R-E or 3VZ-E ENGINE harness, near the ECU connectors. There are the 2 connectors that join the engine harness to the body/dash harness, one of these is needed. Once an order is placed, we will send a picture of the connector needed and a label file (for print) that can be used to send the core connector in a USPS Small Flat Rate Box. Cut the connector needed from the ENGINE harness w/ ″ of wire lead. Note: we will fill the core connector w/ new wire terminals.
Only logged in customers who have purchased this product may leave a review.
Swap 22r to 3rz
Kolya and I have known each other. For a long time, we went to the army together, and after the army we decided to go to college. A diploma, as they say, does not ask for food, but it can come in handy, and knowledge is not superfluous. But Kolya constantly gets into some wonderful adventures.
We walked in the park in the evening, the three of us, Vitya and I went to the toilet, we come to.Project 3RZ - Engine Conversion Part 1
When the worries and doubts that excite the soul had not yet arisen. No actions have yet been committed that shock not only those around them, but also myself. When everything was still not so irreparable.

In a past life, I was engaged in different sports sections, but this knowledge is not suitable in this situation, but the muscle. Memory of this body is significantly different from what I felt before. The hands alternately rotated the blade in their hands, describing an eight in the air, then a couple of sharp swings from one side and the other.
My rival, apparently considering this a sign to attack, began to move towards me. And I was euphoric.
