I reused yhe 22r mounts both frame and engine.

I cut the mounts off the frame with a pladma, flush. I bolted them to the 3rz. I set the 3rz in the frame to see how much I needed to narrow the mounts. I think I took out .75 on each side. I set it back in there, while.hanging from the cherry picker with a little weight on it. And put it exactly where I wanted it. And tacked it in. Then I bolted up my trans, and case, and got that all lined up being the engine mounts were tacked they allowed flex. Then I tacked all that in. Checked clearances and welded it in.

My engine is almost an entire inch more forward than all others I've seen. And I've put over 4k miles on it now and it hasn't missed a beat.

Ended up cutting the top out of the tacoma tank and welding that into my tank. Didn't blow myself up!

Got a problem. Engine runs but has a miss.

Scanner says its a P0301 which is a Cyl. 1 misfire. Replaced the plugs, new coil on cyl 1, checked the injector with ohm meter, it was in range, swapped injector #1 with #2 and it still misses/throws the code on cyl 1. I pull the plug out of cyl 1 and it is black and dry. Anyone have any ideas? Going to run some seafoam thru it tomorrow and replace the plugs with Denso plugs afterward.

Engine ran in the donor truck without a check engine light before I removed it. Im stumped.

Looks correct to me. That's the numbers off what I got when I ordered from Alex at chilkat.

I ordered everything yesterday, found a Toyota dealer in Maryland, 223.00 for everything

can anyone verify that upper intake is the same on 4 port and 8 port, thanks

SqWADoosh · « **Reply #1387 on:** Mar 31, 2016, 12:00:28 PM »

My research said it was. Haven't actually done it though.

HogCanyonHopper · « **Reply #1388 on:** Mar 31, 2016, 06:01:37 PM »

The plenum is the same. Only the intake runners are different. Go with the 8port runners

1985CRAWLER · « **Reply #1389 on:** Mar 31, 2016, 09:17:45 PM »

Yep same thing , I've swapped them over , the later style does have a different iac then the early ones , both essentially work the same , hell I even put a 4 port intake on a 8 port head , worked fine

Carolina82 · « **Reply #1390 on:** Apr 02, 2016, 10:02:06 AM »

Found out whats causing the miss.

Compression check says:
Cyl #1 - 60
Cyl #2 - 168
Cyl #3 - 155
Cyl #4 - 175

I know with the early 3RZ motors there was a AUTO ECM and a manual tranny ECM. With the 2000 and later ECMs (coil on plug design) I'm not seeing the same designations on the outside of the ECM. I asked a couple wreck yards and they are telling me there is only one type of ECM for the later motors. Can anyone confirm this is correct?

I found my motor and I'm going to pull it tomorrow. Its coming out of a 2000 4Runner with an auto tranny. I told the owner I didn't need that ECM... and started searching for a ECM from a manual tranny vehicle... but now I don't know what is right. Would be great if I can just keep using the original ECM with the motor.

swilson · « **Reply #1392 on:** Apr 05, 2016, 01:26:59 PM »

Thanks for the p/n. I'll see what the dealer wants for it.

For $1000 I'm getting a 119k mile motor, harness, motor mounts, all emissions equipment and full exhaust. Still running. I'll hear it run, check compression, and then pull it myself.

Next I need to track down a w59 bellhousing, w59 fork, and the correct ECM

I would get all heater hoses, from the heater core including heater valve, also clutch slave is on drivers side, so hard and soft lines too, I'm using hard fuel line too, they route down drivers side away from exhaust

redneckcustoms13 · « **Reply #1394 on:** Apr 05, 2016, 04:43:24 PM »

His heater valve should work. I'm using a 3rd gen valve.

there are different ecms for all years manual vs auto. my 2001 was an auto ecm, I had to find a manual 4x4 ecm from ebay. I had heard you wouldn't be able to pass the California ref with an auto ecm in a manual truck.

How would the ref know which ECM it is? The 2000+ ECMs don't have any markings to distinguish auto from manual.

I stand corrected on the year. When we pulled the motor out of the 2000 4Runner it said ECT on it, so its obvious its an AUTO. Must have been a later year when they stopped putting ECT or MT on the ECU labels.

Next question... for someone who has gotten their 3RZ swap passed the CA referee... since my engine came from a 2000 4Runner AUTO, am I required to find a 2000 4Runner MANUAL ECU, or are they not that picky? Can I just any year/model ECU for a coil-pack, manual tranny setup?

HogCanyonHopper · « **Reply #1397 on:** Apr 09, 2016, 07:11:06 AM »

you should be fine with a different year ECU for a 3rz MT. should be pretty easy to find one for a 98, 99, or 00 MT

Thanks. I'm also confused I how you tell which generation your motor is. I thought i read that the 1st used a distributor, 2nd had 2 coils for the four plugs, 3rd was coil on plug. My engine came from a 2000 model, but is coil on plug. Should I be looking for an ECU from 2000-2004 model? Or 98-2000?

I think your best bet is to pull v.i.n. off of donor vehicle, then look up ecu # on like Toyota parts online, then you'll have a correct part# to search with

swilson · « **Reply #1400 on:** Apr 09, 2016, 03:49:38 PM »

Thanks for confirming my suspicion. My donor is a CA version and does have two cats & four coils. Sounds like 2000 was a transition year where CA got the 4 coil motor earlier than the other states.

Hello all is there any difference between the 4x2 motor & ecu & the 4x4 motor & ecu ? I've found a good low km 4x2 motor & ecu. Any disadvantages ? I've converted my 84 extra cab pickup from 3y to 22r then changed it from 22r to 22re & now I'm thinking of going to 3rz. Also has anyone got a PDF version of the workshop manual they could email me or download ?
Thanks in advance Dan

My 3rz is from a 2000 tacoma with 2 cats. I got the exhaust ran and installed the 2 o2 sensors. 1 before the front cat and 1 after the rear. Is there a certain placement these o2 sensors need to be? The reason I am asking is my truck burned a valve and im wondering if that had something to do with it.

did you burn an exhaust valve? if so, when was the valve job done. seems to be common on these motors

Yes it was a exhaust valve on the #1 cylinder. From what I know it never had a valve job. It was skipping a little when I first got it running but eventually got worse after I ran it a few times (less than 10 miles). I just want to make sure its not something i've got wrong that made it burn the valve.

OVRAROK · « **Reply #1405 on:** May 08, 2016, 05:13:33 PM »

What do you mean by skipping, jumping timing, or running rough, has motor been pulled apart

I'm inclined to think the problem existed before your engine swap... Not because of your exhaust. Did you get to hear the engine run before you bought it?

I had a 2000 CA 3rz Tacoma with 2 cats and only ran a downstream cat and had a simulator on the rear o2 so I didn't get a CEL, my motor too had a burnt some valves but it was from before I even swapped it in I'm sure , it had a popping sound and was down on power , like mentioned valve jobs are super important with the rz motors

I should do mine this winter. Its only got like 60 some thousand miles on it though.

HogCanyonHopper · « **Reply #1409 on:** May 09, 2016, 05:49:06 PM »

I've never done the valves on my motor. I get the sneaky feelin' it isn't like doing the valves on a 22RE
