Perfect... Now I just have to get the money to do the swap. Probobly gonna cost me around $2000 I would assume.

The 05 Tacoma has a 2.7L inline four (2TR-FE) coupled to a R155F gearbox.

I wonder:
1) What is the input shaft length of the R155F gearbox?
2) Will the 2TR-FE bellhousing bolt onto a 3RZ-FE block?

I am considering a 2rz swap. I found a very cheap low milage 2rz.. the problem is that it is from a yard and they are selling w/o alot of the accessories I need. Bellhousing, starter, computer etc. Are there any parts from my 22re that will work on the 2rz (motor mounts, alternator, etc.)? How interchangeble are the 2rz and 3rzs? My understanding is that they are nearly identical. 3rz is just a stroked version of the 2rz.

My recomendation to you is to find something more complete. you will spend less money in the long run if you buy something fully dressed. And it will an easier swap that way.

About how much would I expect to pay for a decent 3RZ?  How much does the swap usually run?  I have a '85 Toy pick-up w/ a 22R.  I have dumped a decent amount of money into the 22R recently and it still wants more. :shake_head:   I re-did the timing chain, water pump, head gasket, and clutch.  I now think that my rings are going so I want to see if the cost for a engine swap would cover the power increase.  Thanks.

2) Will the 2TR-FE bellhousing bolt onto a 3RZ-FE block?

That is a good question and to add to it:

3) Will the 2TR-FE Bellhousing bolt to the R150F or R151F Tranny?

That's what's holding my up from seriously looking into this swap since I don't want to swap my turbo tranny out for a 'lesser' tranny.

Well I did a bit more than most of the guys here, I also swapped out the dash and everything behind it. All entire wireing harness from head light to tail light is tacoma. Same with everything under the hood. And I got lucky cause I didn't pay a thing for the Tacoma I used to swap everything out of.

This is :offtopic: a little but lets segway a little shall we?  It seems that the TRD supercharger is a little hard to come by at a reasonable price.  If another brand could be used what would it be.  I see that Whipple makes a unit for a PT Cruiser :reg: I wonder if that would be a possible alternative but I have no idea what the cost is.

That's what's holding my up from seriously looking into this swap since I don't want to swap my turbo tranny out for a 'lesser' tranny.

Since the R155F gearbox is a 'R' series item, it should bolt to the R151F/R150F with no problem. The real issue is twofold: 1) does the R155F have a 160 mm input shaft like the other two? 2) will the 2TR-FE bellhousing fit the 3RZ? If the answer is yes to both questions, we have a bellhousing to mate the R151F to a 3RZ. Simple as that!

Heres some good info to know about what should be level when positioning the motor. Its NOT the upper plenum like I was told. What you should level to is the PS cap / reservior.

Heres some pictures of a stock tacoma in relation to motor placement / rotation. Crossmember and PS cap / reservior is level, Upper Plenum is ~ 3 1/2 degrees rotated down to the passenger side.

Then for my application 3RZ, W59 bell housing, W56 tranny, gear T-case I found that the PS pump cap needs to be rotated down at 1 degree to the passenger side to make the T-case level to the frame. you can also see that my mis alignment from the PS cap to the plenum is only 2 degrees  and not the 3 1/2 degrees like the pictures I posted above and I have no explaination of that.

Just wanted to add that I was having some major problems getting teh factory tach to work with a twin-coil 2000 3rz. what I ended up doing was using a 10K Ohm 1/4 watt resistor mod that most of the 5vz-fe swap guys have to do to get their tachs to work. Anywys it worked like a champ for the 3rz!!!

Heres the location on a late model second gen tach. (my v6 tach looked like this)


Heres the location on my 2wd 85 22RTE second gen tach.


And here is the post talking about it in all its glory.....

Since the donor vehicle in my conversion is for a truck that orignally had a 22RTE (turbo motor), the wiring harness and cluster is different than the standard and very common 22R or 22RE motors, I decided not to list the vehicle connections I made on my vehicle because I'm sure it would cause more confusion than good. Plus since I don't have an actual wiring diagram for the donor truck, I can't label the plugs correctly which would just double the confusion. And please don't email me in the future asking me where I connect such and such a wire - because I'm sure in a month I won't remember...

First I identifed the wire plug designation call-outs that were on the ECU (E5, E6, E7 & E8) and the end of the motor harness (1K2 & 1K3).

Then I figured out where they plugged into the taco dash harness (E5, 1K2 & 1K3). and I found the OBD2 Data link port which is (D7).

Now for the book work....I first made a list of each wire color per location of the plug. Then using the GRAY Toyota Wiring Schematics Book I figured out what each wire did. and I listed whether I needed it or not. Then I removed each wire that I didn't need from each plug and spooled up that wire. Lastly I chased each wire for each plug and cut that wire trying to keep as much of the orignal wire length as possible which made hooking them up to the vehicle much easier. you can also see that I used a label maker to label each wire just like I did on my previous 7M swap..

So heres the D7 plug done.... (4 wires left)

1K3 - I removed all the wires from this plug so I didn't even bother to take a picture of it. (0 wires left)

Edit - I ended up putting (1) wire back into this plug for the 4wd indicator switch

And as promised here is the video of the very first test drive, burn'n rubber and all!!  Well kinda - since there is no traction bar installed yet, it spun the rear tires while hopping down the road until it got enough traction and shot off like a rocket....you will see. and surprisenly it left about 7-10 feet of dual rubber stripes in the road even though it doesn't look like it in the video.

Well heres my driving impressions so far of the 3rz-fe swap into a 85 extra cab....

I took the truck to the dunes Saturday and all I can say is WOW! I have a permanent grin on my face. This motor has really nice low end torque and it will rev right up to redline easily. I did almost all my dune running in 1st gear high range! (I couldn't do that even with the 7m -  it didn't have the low end grunt and would stall out very easily.) The 7M has more top end power for say high speed (45+ mph) drifting but the 3rz equals or betters that on everything else! I had no problem climbing some of the bigger dunes where you would be hard pressed to get a 22R/RE up them. and if the motor started to lug down you could downshift and the vehicle would lift up and keep right on going. Highway driving is also nice - where Pete (project_blu) and Tyler (yellow first gen) would have to down shift on the hills I could just stay in 5th and they would just keep up with me. if I downshifted I could pull away fairly easily.

I really don't know what else to say other than if you get a chance to test drive a 3rz swap - do it! but your wallet might hurt afterwards.

I also suspect why the 3rz swap is so nice in the first and second gen trucks is because Taco's are quite a bit heavier so the motor feels more powerfull than if it was in a heavier Taco.

On my drive over to the coast (approx 90 miles), I got 18.5 mpg with a 55-60mph average. Can't complain about that.

So my finaly option is that teh 3rz is WAY better for a trail rig swap than a 7M. teh &M is just too high strung where the 3rz has tons of grunt with a great midrange power!

hey bigmike didnt you mention somewhere that marlin will be working on a 2.7 kit?

since i have a 92 auto can i just swap out the bellhouseing from the newer auto tranny?
and to make this clear since i'm using the autotrans i'll have to swap in the ecu from a 5spd?
thanks

btw good job on the swap and wireing notes!

Nothingface5384,

Yes, we are working on a couple of products for the 3RZ right now, but at the moment, nothing to aid in an engine swap.

We have already have an engine mount jig prepared, but we are still waiting for some other things to get finished before we take a step forward on the 3RZ swap product listing.

Regards,
BigMike
