Topic: Question for the 3RZ pro's

[brc]

Does anyone know where I can get an adapter to go in between the 3RZ and a SM420?  I am building a new light weight cruiser buggy and want to use the 3RZ in it.  I have already located the moter and associated equipment I am picking up Saturday.  I was considering running my extra 85 four runner tranny and duals but LCowner suggested the 420 and toy box.  I am thinking though the 5spd and duals will be lighter I have a write up on it in the Land Cruiser section right now if your interested

Any ideas for an adapter would be greatly appreciated

[BigMike]

Yeah I was going to suggest that the W56 would be lighter...........

I do not know of anyone who makes an adapter to run the SM420.

Thanks BigMike I couldn't find one anywhere.  I am hoping for the buggy to end up about 3800 lbs do you think the 3RZ will pull it off road ok?  I don't run anywhere where I will need really high horse power I just want light and reliable and I am building it for something different.


Part of my reason for going to the 3RZ is that I read your write up thread BigMike and you seemed really pleased and I have already done the cruiser with a v-8 and power is great but I am looking for low wide stable and reliable now and not costing me $40 in gas everyday I am wheeling

Kind of ironic though spending 10 grand to build a buggy to save 40 dollars a trip in gas.  Pretty warped logic I would say.

[BigMike]

Well, 3,800lbs seems mighty heavy for a buggy, but none the less, it does fall lighter than both Marlin's and Dean's 3RZ-powered daily driven rigs, which I can easily say are great dd rigs!

For reference, my 1981 dd weighs 3350 lbs, runs 35" tires with 5.29s, and it has been proven (through multiple witnesses) to be quicker accelerating then the following vehicles:
1984 2WD 5spd 22R-E pickup (little street 2WD tires, no chance)
1986 4WD 5spd 22R-TE pickup (33" tires with TEC Turbo and Intercooler, Almost dead even with me)
1983 4WD 5spd 22R-TE pickup (34" tires ~400 pounds lighter than my truck with no bed or interior, yes a Turbo 1st gen)
1993 4WD 5spd 3VZ-E pickup (35" my truck SPANKS 3.0s BIG TIME!)
1988 4WD 5spd 3VZ-E 4runner (29" stock tires, sorry, no chance)
Turbo 22R-TE's have a better chance at beating me then 3.0s. Seriously, the 3.0 is just awefully slow compared to the 3RZ. Funny that the two have the same peak horsepower and the 3.0 beats the 3RZ by 3 ft-lbs torque. HA! Where did all that power output go in the real world?! (!)

2002 4WD 5spd 5VZ-E 4runner (35" tires, out pulled the 3.4L V6 4runner on all hills up Hwy50 towards Placerville)
1997 4WD 5spd 5VZ-E Tacoma (35" tires, I can beat this 3.4L V6 Tacoma 0-60 and hang with him until 85 MPH. He takes me above 90)
1996 4WD 5spd 3RZ-FE Tacoma (stock 31" ? tires, yup, I beat my own blood)
The problem with the 1995.5+ trucks is that they are just too heavy. It wouldn't suprise me if I have a better weight-power ratio than a 3.4L Tacoma.

The 3RZ is an AMAZING Engine for a 4 cylinder. It beats a boosted 2.4 L engine, it beats a 3.0 V6, and it can easily hang with a 3.4L V6.

The most incredible experience I have ever had off road was last Nov. at the hammers where I rode in a 3RZ-powered buggy. Granted it was light weight, maybe 2400ish pounds, but WOW. It was like a go cart, like nothing I had ever experienced off road before.

Even still, if you are hungry for more power, then Supercharge it. The Smog Legal TRD Supercharger kit has recently resurfaced onto the market place. With an advertised 35-55% increase in power (without intercooling) it is a no brainer for someone who is looking for lightweight Toyota-reliable performance from a 4cylinder that can smog-legally develop 235 HP and 275 TQ. (I know Smog laws dont apply to a buggy, but I just love saying that)

Thanks for the info BigMike.  I am looking at 3800Lbs or less because this is a cruiser frame and maybe not a "buggy" as everyone else see's it.  I am going to run my full width 60 and 14 bolt on my cruiser frame along with the cruiser tub (most of which I am replacing with aluminum).  I will still be able to fit a soft toip and doors as wheeling in WA State can be weathery (read crappy weather) at minumum.  I am looking into chromoly right now for the cage and bumpers.  I figure my 40 I wheel now with stock width cruiser axles and 38.5's full hard top weighs 4815lbs. 

I am just going to run the 3RZ with the W56 and duals in it.  I am going tomorrow to pick up the engine and all related stuff.  Thanks again for all you info BigMike

This is off-topic but  where can i find a 3rz?  I'm in Vegas but willing to do a little traveling need be.

[brc [OP]]

Check the Wrecking yards, Mine is coming out of a 04 Taco w 19K on the ticker.  I think if I remember correctly BigMike got his out of 95 T-100 2wd (don't quote me I could be wrong).  I will have experience pulling it out tomorrow.  Hopefully in my new toy shortly after that.

You can hit BigMike to find out exactly what his came out of.

[BigMike]

brc knows his stuff. My engine did come from a 1995 2WD T100

hopper, first go to http://www.car-parts.com

And then search for 4cyl Engines from:
1995-1997 2WD T100
1996-2004 4WD Tacoma
1996-2004 4WD 4Runner

Once you find a wrecking yard that is selling the engine, then I would recommend calling the yard and inquire about the vehicle that the engine came out of. Was it a frontal impact? Was it T-boned? Did the vehicle catch on fire (a burn job)? I would then ask if they still had the ECU and the wiring harness with all attached sensors, and then I would ask if they could sell me everything as an Engine Swap package.

It doesn't matter if the engine is pulled from an Automatic or Manual vehicle. Even if you get an Automatic setup, all you will need to do is just get a Manual ECU from that same year (very cheap, under $100) and you are done.

Below are the prices that I feel are resonable. Depending on mileage you will get different quotes. I am assuming everything here including the engine bay fuse box, starter, flexplate (if Auto), Flywheel with clutch (if Manual), interior crowl harness and fuse box, gas tank and purge canister. I recommend the gas tank only if you are using a 3rd generation (2002?-2004) 3RZ because of the added sensors for the ECU and Smog. You don't need Of course you won't need the 3RZ radiator or heater core, or power steering rack, nor will you need the head lights, blinkers, horns, wiper motor, interior lighting, etc, all of which I mention because they are wired together so make sure the yard is not charging you extra for that stuff.

1995-1997 Style (1st generation) 3RZ Complete Swap package: $500-$1000 (gas tank not needed)
1998-2001? Style (2nd generation) 3RZ Complete Swap package: $700 - $1500 (gas tank not needed)
2002?-2004 Style (3rd generation) 3RZ Complete Swap package: $1300 - $2000 (I recommend getting the gas tank as well)

For the 1st and 2nd gen engines, any Fuel Injected Hilux fuel tank will do. I am running a 1993 Extracab V6 (17 gallon) EFI tank in my truck.

Just for reference:
I paid $500 for my 1995 3RZ (140k miles) with everything I needed except (no gas tank).
Marlin paid $650 for his 1996 3RZ (80k miles) with everything he needed (no gas tank).
Bevin paid $1950 for his 2003 3RZ (14k miles!!!) with everything he needed including the Tacoma gas tank.
Dean paid $2100 for his 2004 3RZ (9k miles!!!!!!!!) with everything he needed including the Tacoma gas tank.
Angelo paid $700 for his 1998 3RZ (60k miles) with everything he needs, but he needs to repair part of his harness.
Marlin just recently purchased I believe a 1996 3RZ (80k miles) with everything including the gas tank for I believe $1000? I'll need to ask him about it, I forgot..

Good luck
BigMike

I went and pulled the 3RZ today.  I got just about everything i could.  I pulled the engine gas tank wiring harnesses ECU power steering hoses.  I also pulled the power steering cooler. 

Man that wiring harness is going to be fun.  I pulled the interior harnesses as well as my cruiser has 0 wires in it right now.  I figure if nothing else I can use the extra fuses for C/B and other stuff.

BigMike- Do you happen to know the length of a W56 w/dual cases?  I am going to have a 100 in wheel base I may end up going with a single case and 4.7's.  THANKS

brc

[BigMike]

I just measured it, and the W56 (including bell housing) is ~26" long, and a t/case (front face to rear flange face) is ~14" long.

So a single case W56 setup is 40"

And a dual case W56 setup is 46.5"

[brc [OP]]

Thanks BigMike.  I appreciate it.  I weighed the W56 I pulled out of a 85 four runnerr and it weighed 67 lbs including the bell housing minus gear oil. 

I am going to start stripping circuits out of the harnesses this week.  The clutch that came on the motor is in awesome shape.  That was a bonus. 

BigMike are you running a header on your 3RZ yet?  I am contemplating building my own there is a header place in Michigan that has the flanges and all the pre bent pieces to build your own out of stainless.  I picked up a Syncrowave 200 tig machine and should be able to weld them up pretty sweet.  Also what are you running for exhaust I think you were using a flowmaster if I remember correctly what size 2.25 or 2.5?

I hope to get this going before long.

Thanks again BigMike

[BigMike]

Yup, we (Marlin, Dean, myself) are all running Downey 4-1 headers with much delight



The only trouble I had is that the EGR line was badly warped so I had to sand it down to prevent leakage. It has not leaked yet.

[brc [OP]]

I may just go with the downey as well I have to see how well it will fit in the cruiser frame/tub and what there return policy is because I hate to have to pay for it and then have it not fit. 

I like your air filter element set up thats pretty sweet.  I only hope this motor conversion turns out as well as yours in your truck.  I took the complete harnesses inside I figured I could just use everything from the taco since the wiring harness is new. 

I ordered a FSM for the Taco and amd going to start all the wiring I can eliminate before I put the motor in the manual should be in thurs/fri.

I just spent most of the day completely cutting up my original tub.  Tomorrow after work I start making the frame work for the aluminum sides and rfear tub floor.  I am hoping to have the tub and floor done by friday and put the tub on to fit the motor and trans in. 

Man i have a whole list of stuff to get done it is like never ending but I'll eventually get there.

THANKS for your help BigMike!!!
