Topic: The Official 3RZ Knowledge and Database Thread

No, it's because my donor didn't have the right setup for using a evap system with a stock '85 gas tank.

I see from your write-up that your donor was a 2004 (3rd gen engine). Here's a summary of what I think I've learned so far:

1'gen  95-96  Distributor, EGR,     1 Cat,   1 EVAP Purge line,  1 EVAP vacuum line,  1 solenoid
2'gen  97-99  Dual  DIS,  EGR,      1 Cat,  ?  EVAP Purge line,  ? EVAP vacuum line,  ? solenoid
3'gen  00-04  Quad DIS,  no EGR, 2 Cats, 2  EVAP Purge lines, 4 EVAP vacuum lines, 2 solenoids, int fuse box eliminated easier/fewer circuits

Can you fill-in, add to and/or confirm any of this?

[TacoRunner]

Change the 3'gen to 00-04

05' they came out with an all-new 2.7-liter 2TR-FE 4-cylinder rated at 159 hp and 180 lb·ft. of torque

Thanks, edited the original post. Can't find any online manual for 2'gen so I can't confirm EVAP configuration. Also skeptical of EGR info for 3'gen since 2000 FSM shows one. Maybe confusion with 2RZ?

[BUDDERS]

My '04 3rz came with a EGR system, but when I changed to a 2001 2rz harness and computer, there was no connectors for the EGR stuff, so I just capped it off.  I was pretty scepticle about the 2001 not having EGR, but I confirmed it at work.  I'm going to try and smog it as a 2001. wish me luck....

BTW, with a 2001 Evap system, you only need one line back to the gas tank - the evap canister sits under the hood.  On a 2002 and newer, the evap canister is by the gas tank and requires modifying your gas tank to work.  I just used the stock evap line and exteded it to the canister on the driver's side fender well.

WOW good info, thanx

I wish you all the luck in the world! But I would have though the referee would go by the engine number? I didn't think you could mix and match?

Wouldn't you have to change the ECUs fuel map to compensate for the difference in engine displacement? Also, I thought that the 2RZ did not come in 4x4s? Is a referee going to care about that? I don't know why the engine would care weather it was in 4WD or 4L (my 22R-E doesn't) but the 4x4 ECUs have inputs?

BTW in the 2000 FSM they show a small round canister for the 2RZ (like my 86 has) and a large box canister for the 3RZ. The box type has the extra vapor pressure sensor that the ECU uses to verify that the EVAP system is actually working. I see complaints about the ECU trowing codes when you overfill the gas tank on the version with the canister near the tank.

Do you have one or two catalytic converters?

[tasherman]

After more research, I found several dozen Executive Orders on the California ARB web site that define the emissions configurations and requirements for the 2RZ and 3RZ vehicles. It took 8 hours but I managed to distill it into a table .

Abbreviations:

EO = Executive Order
MFI = Multiport Fuel Injection
SFI = Sequential MFI
EGR = Exhaust Gas Recirulation
O2S = Oxygen Sensor
HO2S = Heated O2S
AFS = Air Fuel Sensor
HAFS = Heated AFS
TWC = Three Way Catalytic Converter
WU-TWC = Warm-up Catalyst TWC
50S = 50 State
CA = California

Notes:

If EGR is blank then the vehicle was not equipped with an EGR system.
If the O2 sensor is followed by (2) then there were two of that type sensor.
If there are two O2 sensors listed than there was one of each type.
If the CAT is followed by (2) then there were two CATs of that type.
If there are two CATs listed than there was one of each type.
If there's a / followed by another digit after the ECM P/N then there was a change during the production run.
If two vehicles have the same EVAP Family number then they have the same EVAP system (I think).
If two vehicles have the same Engine family number then they were certified under the same EO.
and are very similar but not necessarily identical (again I think).
The 2001-2004 EOs did not contain model or ECU numbers (I don't know why).

If I found all of the EOs then the table should contain all models that were sold in California.
The info for models marked 50S should be valid for other states.
Since this info came from the California ARB, there is no info for 49 state vehicles - SORRY!

Finally, I make no warranty that the info is correct. There were some obvious typos in the EOs which I corrected but that also means there might be others which I didn't detect and it assumes that I didn't make any typos myself .

Nice Tech, I like that. Awesome job. Thanx

[chunkybutfunky934]

Yea very nice job thank you!!

[BUDDERS]

I wish you all the luck in the world! But I would have though the referee would go by the engine number? I didn't think you could mix and match?

Wouldn't you have to change the ECUs fuel map to compensate for the difference in engine displacement? Also, I thought that the 2RZ did not come in 4x4s? Is a referee going to care about that? I don't know why the engine would care weather it was in 4WD or 4L (my 22R-E doesn't) but the 4x4 ECUs have inputs?

BTW in the 2000 FSM they show a small round canister for the 2RZ (like my 86 has) and a large box canister for the 3RZ. The box type has the extra vapor pressure sensor that the ECU uses to verify that the EVAP system is actually working. I see complaints about the ECU trowing codes when you overfill the gas tank on the version with the canister near the tank.

Do you have one or two catalytic converters?

I have 2 catalytic convertors and the large box style evap canister with a vapor pressure sensor and another VSV.  I spoke with a guy from the CA BAR to make sure what I'm doing was going to pass and he said as long as all the evap system was hooked up and it burned cleaner than the 22re that was previously in there, they should let if fly.  He said the only cars they were really cracking down on was the hondas with motor conversions.

Thats great, If you look close at the info I pulled from their web site it confirms what you said: that the 2001 2RZ and 3RZ did not have EGR. Its funny because thats the only year the 3RZ did not have one. I guess you hit the jackpot! BTW I see some people are saying that the CAT(s) have to be on the same side as the original application. Do you have any more info on that?

[BUDDERS]

Yeah, with the new smog laws in CA, the cats have to be in the same configuration as the donor motor - so I'll have to re-do my exhaust before I run it past the smog ref.  Right now the pre-cat and the regular cat are further downstream than normal, and they are both on the driver's side now.

since we don't have emission laws here where i live and i have the best wife in the world  I went ahead and ordered the lc pro fuel injection kit today for my swap.  When i eventually get this thing going i will post up the results.  As of now the block is wrapped up in my garage with all new bearings, pistons/rings and timing chain while i wait for engnbldr to finish up the head.  My plans were to do a stock rebuild on the motor and with LC's kit i'm able to run a air filter directly on to the throttle body since there's no MAF needed.  I'm also going to run the stock mini header to a 2 1/4 in exhaust without the cat.  Thanks for all the great advice!

[*ROKTOY*]

Personnaly, I would open up the exhaust to 2 1/2", that's what I run. I do have dual case's and 4.7's so off road is fine, but on road is excellent I have hit 90 MPH and it was still pulling hard. Yes that is on level ground.

[kauaikid]

i'm running the same dual case setup as you and would've considered it if i hadn't recently redone the exhaust with the 2 1/4 so my plan was to just run the 2 1/4 crossover and retain the rest of the existing exhaust.  I can hit 90mph now with my 22r on flat ground but it takes a little while and i can't pull to hard at all after that.  I'm really looking to gain uphill power while driving up steeper grades and i guess i just want to say i did a 3rz swap

There's one part of my question about donor vehicles that never got answered. Does it mater if the donor is 2WD or 4WD? I see inputs to the ECU labeled 4WD, 4L, and TFN (transfer case neutral). Why would the ECU need these signals (ABS brakes possibly or are these only needed by automatic transmissions)? Would an ARB referee care? Would I care? Are the 4L and TFN signals available from a RF1A transfer case?

[TacoRunner]

I would have to say yes, it matters.

[tasherman]

I would have to say yes, it matters.

At first I was inclined to agree with you, but the more I think about it, the more I think these signals are used to modify the behavior of the ABS breaks and/or an automatic transmission! So if I'm not going to have either than I wouldn't care. In any case are far as I can tell the RF1A transfer case only has a switch for the 4WD signal, so if it matters how are guys who've done the conversion generating the 4L and TFN signals?

[tasherman]

FYI: Today I spoke to a CA ARB referee from Santa Rosa, and he said that he "didn't think" they would care weather the donor was a 2WD or 4WD as long as the engine was offered in a 4WD. Incidentally while I had him on the phone I ask about exhaust routing. He said the exhaust must be routed the same as the donor. He even said that they had disallowed a 3.4L V6 conversion which had a "mirror image" of the factory crossover (ie; it would have had no effect on the effectiveness of the O2 sensors or the catalytic converter) simply because it was different from the doner!

Im so happy I don't live in Cali with all these crazy car laws!

I'm gonna be running my fuel lines this weekend and have been looking at all the pics i can find on how everyones been doing it.  I see some run it in the stock location and then accross the firewall and some run it up under the drivers side to avoid exhaust heat.  Has anyone had issues with vapor lock due to using the stock fuel lines? And besides the stock heat shield is any other heat protection needed?  Also is the stock fuel line on the older toyotas sufficient to supply fuel to the 3rz?

[Russell_G]

Im running 2.5 on my 3rz, 37mtr's and had bias 36's before. Have no issues on the highway. I will admit i kind of drive like an a55 and find myself speeding from time to time. Speed limit is 75 and because i still dont have my VSS in I cant be 100% sure how fast i was going but my buddy said we hit 100+ one night screwing around on the highway.

Mods
2.5 manifold back, Stock cat, borla muffler and 2 bullet mufflers
K&N intake for tacoma
5:29's
TRD Radiator cap(=1000hp i know)
Other then that bone stock motor

on the trail i have duals with a 4.7 case and i have plenty working for me. I feel like the truck lacks a slight bit down low sometimes but im in CO so im sure it doesnt run like most of you guys in CA or sea level.

Ran the Tacoma lines. My soft lines cross over the back of my cab I havent had any issues due to heat. It was cheaper to do the rear of the line rather then the line across to the filter plus i thought it looked cleaner.

My buddy ran them across the firewall and used stock 22re pump and lines and it runs great. Its all opinion and how you want to go about it.

[kauaikid]

thanks for the info.  I finished my lines the other day and ran them on the firewall using the donor taco lines.  Today i made a new heat shield to protect all the fuel lines on that side.  I'm gonna keep an eye on it and if it still gets to hot i'll buy some thermo tec insulation.  My wiring is all in place so my plans for tomorrow are gonna be finishing up the motor rebuild and maybe drop it in.  We'll see!! 

[1984taco3rz]

anyone have any info on wiring the 1997 3rz yet

[Capt. Crawler]

 

Ok so I tried the mod in post #501, to jump the trans plug. It seems my 4 runner doesn't mind if the plug is even pluged in at all? Although I don't have an OBD II reader and don't know if I have any codes but the motor seems to run perfect.

 So am right to assume that I don't need a "manual" computer to run this engine with a R151.

[1984taco3rz]

im putting my 3rz in a 1984 frame and was wondering how do i center the motor from left to right if i center the crank the tranny looks way crooked or do i center the fan because its offset from the crank any info would be great

[BUDDERS]

I centered the crank in my '85 frame and it was fine.  Just remember the valve cover won't sit level.  Put a level on top of the P/S pump  .  If the trans/engine combo looks crooked with the crank centered, maybe you have a bent frame....

[boggerunner]

with the balance shaft deleate, do u have to run lc's kit, or can u just pull the chain and get the bottom end balanced?

cause i pulled just the balance shaft chain off and have been runnin that way for 4 months now with no problems and alot more power
