Hello peeps,

As some of you know I've been working with my friend Bevin on his '85 shortbed, converting it to a 2003 Tacoma 2.7l 3RZ engine with just 14k miles on it - and I've been slacking and have not gotten any pictures up, so here they are!

I would say that the conversion itself is about 70% done, but I still need to integrate the modified Taco wiring harness into the Hilux interior.

The next chance I will get to work on it will be on the 15th or the 16th of this month, so between now and then, Bevin will get the gas tank modified, install the fuel lines, install the Turbo 3-core radiator, and finish up the rest of the exhaust system.

So without any further ado, let's get to the pics

Bevin had pulled the ol' 22R carburated engine, after it blew it's last head gasket, and had the engine bay all cleaned up before I even got to his house the first time back in June. He got the entire setup for nearly $2,000, which included the computer, complete engine bay fuse box wiring harness, crowl interior wiring harness, complete exhaust/tranny/o2/fuel wiring harness, and he got the '03 Taco gas tank and purge tank, which has the EFI fuel pump and sender, and the CA smog required pressure sensors and floats that we will be transfering over to a modified '85 carburated gas tank.


Here are some pics of the Engine Mounts we decided to go with. Bevin worked his mad fabricating skills and created a bolt-in Hybrid 3RZ/22R Chassis engine mount bracket by using the 3RZ Engine Bracket while maintaining the stock Hilux 22R Chassis Engine Mount Location.

We went this route because it was a cut-free / weld-free setup that has turned out quite nicely Good work Bevin!
In fact, the Tacoma mounted 3RZ uses the same rubber engine mounts as his '85 22R, so he now has an extra set of mounts to boot!

While Bevin was doing some 3RZ sugery, I got to start on the wiring.

Here are some pics from the progress last month. I now have the loom all cleaned up and down to the neccessary circuits, but I do not have a picture of it at this time.

This is about where we are now, and I will take some more pics the next time I am up there, which should be in 2 more weeks. I wanted this project finished the last week of July, but obviously I was way off and didnt make it. Now it looks like we will not have it running until the end of this month Which is kind'of cutting it close, as Bevin still needs to do his suspension and HySteer so he can get that mad beast up to the Round-Up in Sept.

So we've got a little over 1 month left to get all of this done for MCR- More to come later!!

hey BigMike you should start making wiring harness for a conversion kit, that way you won't need to be there on every 3rz swap.

Well, I was going to document each wire, but nearly 80% of the Tacoma wires were removed because those circuits were not related to the engine swap, so instead of doing that, I should just document what wires should remain on the harness. I will most likely do this the next time I get back up to his house (he lives about 30mins away from me) so that we people can have access to this information on the net for free. I think this info will apply for most '00-'04 Automatic Swaps (3rd gen 3RZs). Then when I do Marlin's '96 swap, that will apply to most '95-'96 5speed swaps (1st gen 3RZs). I could do the same for Rocky's '97 swap too (2nd gen 3RZs).......

Al right guys,

I just wanted to let you know that I will be out of town starting tomorrow and will return on the 14th. I plan to resume work with Bevin on the 15th, and I want to try to get it started by that weekend on the 20th.

does the stock 5 speed w56 (thats the one I have I think 87 4 runner) bolt up to the 3rz so that you can use your existing setup without worrying about the tranny and what not.

Absolutely. Since the 3RZ's native transmission (W59) is in the same family/speed as the W56, the bellhousings are interchangeable. So what we are doing is using a T100/Tacoma W59 bellhousing, that has a drivers-side clutch and starter, and bolting that directly onto either a W56 or a G52/54 (uses the same front bolt pattern).

I'd totaly consider buying it if I went that way. Nothing is more frustrating to me and many other guys for that matter than doing the wireing headache.

I really really really do not think I would ever build "available" harnesses, mainly because it would be way to much work trying to order new plugs or locating good used harness, and also, in general, there are four different 3RZ versions:
1st gen: Distributor Ignition
2nd gen: Twin coil DIS
3rd gen: Quad coil DIS
4th gen: Quad coil DIS + VVT cam technology (2005 and newer / 163 HP - 183 TQ version)

So I would have to make at least 3 sets of complete harnesses (assuming that no one can really get the '05 versions yet) and I could never stock those nor find the parts to make them factory bolt on compatible.

So instead, I would like to offer a complete pin sheet showing the required plugs and the required pins that are needed to get this engine running. That way the average hobbyist who knows how to use a soder gun could get the wiring done in a weekend. (I sincerely hope no one would ever do an engine swap using crimp-on terminals        If this is you then dont even do a swap )

Also one last thing where are you guys finding these engines.

Oh man, it boggels my mind how no one can find them. They are litterally crawling all over http://www.car-parts.com Check it out

.......

Ok, I just checked out for '96 Tacomas, and there are over 207 3RZs on there, and that's just from that generation of 3RZs, not to mention the ones in the T100s either!! My advice would be to just start calling up yards. Gather as much info on the truck that brought that engine in as you can. Ask how complete it is, if the harnesses have been cut, what wires are available, complete and what not.

I guess I didn't even think to look at car-parts.com I found on in my town. If its as easy as you seem to make it out to be on the swap (taking into consideration the wireing) I might just look into that. Hope they still have the engine when I have the money for it. Does $1200 seem like a fair price for a complete 3RZ?

I paid $1200.00 for mine with the W59 bell housing, clutch assembly, body harness, engine harness, ECU...of course starter, alternator, hoses & belts, complete air intake, power steering lines, clutch slave, engine mounts...I think that's it.

Here's one on Ebay for $850.00:

Hey BigMike,

U guys gonna offer some motor mounts based on Bevin's design?

Did you ever find anyone making a bellhousing to fit the 3RZ to a R150F or R151F tranny?

Anybody doing/done this on a 86 or later IFS truck without a SAS?

I've got a couple more pics here, lets see........

Looks awesome BigMike keep up the good work.

Well I am hopeing to have it running this Sunday, also this truck is not in Fresno, it is at Bevin's house which is up in the hills..

I would imagine the wiring would be 95% the same, if not completely the same.

Well, I did not record anytime with this one, but I have full records and notes on Marlin's wiring (1993-1996) style, and I will do the same when I do Rocky's 2nd gen engine (97-99?). But for the newer four coil engines, 2000+, I did not take any notes + there are more wires to remove

BigMike

Dude, freakin BigMike, your the man. I wish i had the engine skillz you got. Someday I am going to buy you a  man.

Keep up the good work.

Well, Last weekend I spent all day on Sunday and got the wiring about 95% finished, including a dry start!!

Yup, we added some oil and gave it a crank! Sure sounded SWEET! and I have a video, but it's on my memory card in my camera in my truck right now but don't worry, tomorrow night (Tues) I will be back at Bevin's house and I will take more pics and movies, and I hope to start it up with the ECU and get it running!!! SWEETNESS!

STAY TUNED!
