Bevin's 3RZ Conversion

[gotrocks]

get r dun

[h0nke]

that tank is freakin awesome

[BigMike]

Well guys,

It's been a while and we've been pretty busy at work play!

Time for some updates ya think!

[BigMike]

We still need to finish the wiring at the engine bay fuse box, but since everything wiring related is done, all we need to do is readjust a couple of wires and get it all taped and reloomed for the final mounting.

Which brings me to this first little Video, from Thursday 8/25, about two weeks ago:

First Crank of Bevin's 2003 3RZ Power plant (1,342 Kb)

[BigMike]

And you probably thought we stopped there? Heck No!!





This one is from Thursday 9/1/2005, JUST 6 DAYS AGO!  

BEVIN'S 3RZ IS ALIVE!!! (1,342 Kb)

[BigMike]

You've gotta Love that expression on Bevin's face on that last Video. Words just can't describe how jazzed we are about getting this thing up and running. It's been since June 22nd that we've been working and working, and now finally we've got something to drink over

And just as expected, I know these Automatic ECU's would give us some trouble.....

gettin pretty good at this stuff huh mike?                    

[BigMike]

And as you can see, between Dean's 3RZ that we just got running, and Marlin's 3RZ that we just got running, Bevin's has the most # of codes reported, but the funny thing is that codes P0351 - P0354 are all codes for Igniter #1, #2, #3, and #4. It says something like "Electrical Circuit Failure" or something like that? Well what in the world? The igniters are on the engine and related to the engine harness, the part of the harness that is not even touched for this conversion. Furtherer more, how can the engine be running so well if all four igniters are not working?? So something fishy is definitely going on here, and I've consulted a Master Toyota tech here in town, awaiting his return phone call to see what he thinks...

So basically, Bevin on has two codes, the Automatic Solenoid Codes 753 and 758 (Solenoids A and B). And since this is a common code for Dean and Marlin, it looks like I'll be doing some research to try to get around these codes.

That's it for now, I will be back at Bevin's this Thursday evening to finish the instrument cluster and put the rest of the dash back together, then at that point, the rest should just be plug'n'play bolt-ons, get-the-job-done type things that still remain, so it shouldn't be much longer until this machine sees the roads once again.

However, with the Round-Up approaching, we are all pretty busy around here and I think this Thursday will be my last time to go up to Bevin's house until after MCR4.

Also, since we didn't get Bevin's truck finished and ready for wheeling in time for the Round-Up, I've offered him a seat in my rig as co-pilot for the MCR4, so be sure if you catch my rig on the trail, to swing on by and say hello to Bevin and to tell him that his 3RZ conversion is coming along nicely!

Can't wait to see what this 2003 engine can pack in the hills!

Regards,
BigMike

did u clear the code and retest? chances are that the igniters were disconnected with the ecm powered up and that set the code

[BigMike]

Yup, cleared the codes numerous times, and we even had the whole system unplugged a couple of times also, so I know that those codes are not resetting, so something is up and it's not related to my work or Bevin's. It's just one of the logistics of the job I guess-

[h0nke]

well done mike - you can tell bevin is stoked.

[[email protected]]

bad or no missing ground wire between engine and ecm ,ecm and body  ,engine and body,body and battery,or poor connection at a crimp connector somewherein the harness, or a pinched wire in the harness 
what you'll find I'm sure ,you can never have too many redundant ground circuits you would be surprised at the things a loose ground or connection will cause
hey BIG mike did u give Bevin my message ?u know who this is don't you? if not check your personal messages
if u need any help on any of this stuff or want an extra pair of hands let me know as I'm no busy these days
c-ya grumpy
p.s have scan tool will travel              
tell Bevin i need to come see him soon he will know what for-----                                                

[BigMike]

I am going to his house tomorrow afternoon, so I was going to deliver your message to him then.

I'll recheck all of my grounds and also probe every ground wire I can find to ensure it's grounded. Hopefully we can take it out for a spin tomorrow? Maybe?

[[email protected]]

cool thanks , i would add some grounds to the body and engine just to be safe-if u still have trouble i'll go with you just to get out of the house-i havent seen bevin since i worked on his ranger-how long has that been  
good luck and i'll put in a good word to the toyota gods for you         

[BigMike]

Welp, We've got the ECU mounted and about half of the dash back together, and then I found out that I miswired one circuit and I have to correct that before I put the rest of the dash back together..

As for the truck, Bevin has been driving it all around, up and down the hill, and its doing really good! He took it to Oakhurst last week and got the muffler and the rest of the exhaust installed, but the dummy forgot to mount the 2nd O2 sensor! IDIOT GOSH!

So he's got codes right now for the O2 sensor and for the purge tank, which isnt hooked up yet.

Bevin finished the wires around both front fenders and put them back on.

I would say that everything is finished except for the interior, the tachometer (which will require a Taco tach brain), the purge tank, and a mount for the battery.

Bevin is going to see Rocky tonight, so hopefully they can work something out. Rocky is going to do the Suspension and the HySteer on Bevin's truck, and now that it's driveable, Rocky just needs to come pick it up or something-

I'll keep everyone updated, cya
BigMike

[BigMike]

Oh, I just realized that I had not mentioned that we got it running

Yup, Bevin took it out for a spin about a week ago and its FAST! Pulls really strong, and it still hasnt learned anything because we are disconnecting the battery every night due to my wiring issue. So once I get that fixed, then the ECU will get a chance to learn what's going on- I know my truck runs better the more hours I drive it.

Bevin ended up getting a 3RZ 5-speed ECU for less than $100!!!! And that took care of all of the auto trany codes and also we no longer have an Ignitor code. So dont even get me started about that one. Something was messed up with the stock auto ecu apparently because this 5spd one, everything is a-ok

Gotta love it!

Big Mike,
I'm almost finished pulling a 3RZ-FE out of a 97 2WD M/T 4Runner and I had a couple questions for you before I finish. I should let you know that the engine is going into my 87 22-RE equipped 4Runner.

1st question: Why are you saving the interior wiring harness out of the donor vehicle? All I can think of that I need is the OBD-II Data Link Connecter.

2nd question: You've used the under-hood fuse block for all three conversions you've done, what is the importance?

I haven't been able to find a service manual for my donor engine so I wasn't sure which all circuits I needed.

Thanks for your help in advance.

[BigMike]

Hey b_ripper8, sorry I didn't catch this sooner!!

1st question: Why are you saving the interior wiring harness out of the donor vehicle? All I can think of that I need is the OBD-II Data Link Connecter.

Well, with the first swap I did (first gen. 3RZ), half of the engine related relays are located in the interior fuse box. So I kept that fuse box and also kept the required wires for those circuits.

But then, when I was doing the 3rd gen 3RZ conversions, on both Bevin's and Dean's, Toyota was smart to relocate those engine related circuits up into the Engine bay fuse box, and I discovered that the interior fuse box can be eliminated altogether. But at the time with Bevin's, I instructed him to order the interior crowl harness because I didn't know anything about the 3rd gen harnesses. It turned out that there are only about 20 wires that are needed to combine the right side of the interior with the left side, including fuel pump, OCR, grounds, fuel sender, low fuel level lamp, starter, ignition, and power.

So when we did Dean's, I just used some of my left over Toyota wires and was able to use the exact factory wire color and striping wires to finalize the interior wiring without needing the factory Tacoma crowl harness.

So you are right, it is not needed.
On Marlin's and my conversion, we are using 95-(early)97 style 3RZs (distributor), so if that is the same version as your's, with the distributor, then there are just a few circuits needed *I believe* from the whole interior drivers-side fuse box, but I have not done this to mine yet. I have retained the clutch-start cancel relay and I am routing my electric locker and cb radio through the T100 fused circuits that were already there on the interior fuse box out of convenience. Such as the 15A "Park Lamp" fused circuit and the 20A? "Cigarette" Fused Circuit. There are a couple more circuits there that I can use, like once I put my car deck in, but of course I can just go down to Autozone and get a Fuse Block and make my own circuits.........

which brings me to your 2nd question:

2nd question: You've used the under-hood fuse block for all three conversions you've done, what is the importance?

Well, for me, I like the Factory look of the fuse box because I am not the best at adding relayed circuits to the side of an inner fender wall.
From the 1st gen 3RZ Engine bay fuse box, amongst the circuits that need to be fused, there are also many relays such as the EFI relay, Injector relay, and Starter relay. Also, the T100 fuse box we have contain the large 80A and 50A main fuses for the Alternator and main hot line from the Battery-> Starter-> Fuse box, which powers the whole truck.
And from the 3rd gen 3RZ Engine bay fuse box, it is the same but this time there is no Starter Relay.

There are about 4 or 5 fused circuits that are needed from there....... So, I could have just gone to a parts store and bought some relays and some fuse blocks, and done it all that way, but I just figured it was much easier to retain the factory Engine bay fuse box.

[BigMike]

Updates!!!!!   


Well, A LOT HAS HAPPENED!

After waiting for just over a month for his suspension to get built, we got Bevin's truck back and continued work on the interior, which is nearly finished now.

Let's start with some pics!

[BigMike]

The truck is finally starting to look like a ROCK MACHINE!!!

He got the Marlin Crawler 4" Suspension Kit with Frenched rear hangers. 12" shocks at all corners, and Billet HySteer Arms. We have the Steering Stabilizer, but it has not been installed yet. Bevin bought a welder, so that should go on soon..

But the problem with this is that he bought the entire Suspension kit from us back in the Spring time, and didn't get it installed until now. So, he had these parts sitting in his garage for a long time, and we didn't realize that he had both 4" front and rear springs. But with a frenched hanger in the back, you would want to run a 5" spring to level out the vehicle, which trading a never-before-installed 4" rear springs for 5" springs wouldn't be a problem, but with all of this moving and business merger that occurred in these past couple of months, we had ran out of 5" springs, and I believe we are still out of stock on them.. So for now, he is running the 4" rear springs and hence, the truck is not level. Even while keeping the factory front shackles, the front end is much higher than the rear!

But once we get some 5" springs in, then we will switch them and put some longer shackles on the front end. Then his truck will be raised a good inch or two

Here is what his Engine looks like now, 99% ready for the Smog Referee to approve this conversion, and make his truck Smog Legal

[BigMike]

Bevin has been driving this mad machine everyday down the hill and into Fresno for work

He has SOOOOO MUCH POWER with the little 30s. He can do a burn out all the way into third gear on demand!!

All that is left for smog, is to install the 2nd o2 sensor (huge!!) and hook up two vent lines from the purge tank. We had a 2nd o2 sensor, but somewhere during the suspension install and the muffler shop, it got misplaced?? Bevin isn't pointing any fingers, but it is crazy because he knew that it was in the glove box for sure and we can not find it anywhere. It was a used 4-wire o2 sensor that I gave him for free, but now it looks like he'll be out $150 for a new one........

So, moving along, I got the interior all back together Bevin bought some new carpet from Lowes? and replaced it and it looks really really great!! He also make some brackets and mounted his Honda Accord Bucket Seats which are mighty comfy!

[BigMike]

And for the more keen eyed reader out there (notice 3rd pic in previous post), yes, during all of this work, TURBO (Tim) himself! put together a Clocked MC08R10 Dual Case Crawler for Bevin!!

So now with his factory 4.11:1 diff gears, Bevin has become 84:1 !!!!!! Nice
That means that his 3RZ can put out theoretically 14,868 foot-pounds of RAW BRUTAL TORQUE!!    

[BigMike]

And that is where Bevin is now

It is really starting to all pull together!

Also, a couple more things that I have not taken a picture of yet, are a Front Range Crossmember setup, just like mine with the Clocked/Rotated Crawler Adapter, and also a 0.189 wall High Angle front Driveline. Next time I see his truck I will take some pictures of those

I mean seriously, this is becoming a beast!! He is in the works of getting a rear E-Locker and a front lunch box style locker. He will run 5.29:1 and most likely run 35s for now. Then he will get some Nerf Bars and a Front Bumper and he will be


He got to take it out with me to Bass Lake, up to Shut Eye Peak last weekend, and it did really well!! We ran into snow, and then straight ICE that even I could not do anything on with my truck locked up and super low gearing. Forget it. I even fell on my butt three times just walking around my truck trying to take pictures!!

So I will have to post the pics and a report from the trip in the Trip Report section, hopefully tomorrow! I am so tired right now!! Off to bed!!
Way to Go Bevin!
Cya!
BigMike

[b_ripper8]

Thanks for the reply BigMike, that helped with some questions. I'm kind of at a stand still right now until the factory wiring manual for my 87 comes in. I also returned the 5VZ oil pan set-up I ordered by mistake and my 3RZ stuff is in the mail so I can hopefully get it mounted soon.

I have the DIS style 3RZ (1997) but looking through the wiring diagrams it looks like I'll be keeping the interior fuse box for the same reasons. I think I'm going to run some kind of distribution box to run power from my alternator to all the fuseboxes. How did you go about this?

Another problem I ran into was that the pick-n-pull I got everything from couldn't sell me the exhaust collection pipe because it has an OBD II CAT on it so I'm not sure what I'm doing for exhaust yet. I have a fairly new Magnaflow CAT and Flowmaster 40 which are both 2.25" so I think those will work. Do you know if Toyota used a two-way or three-way CAT? Either way, I don't think it will effect my 2nd HO2S because it's only picking up O2.

Keep it coming with more info on Bevin's truck. The thing looks awesome.

Also, I'll post up the part #'s for the 3RZ oil pan conversion once it arrives in the mail.

Mike, do you think this is a more cost effective swap than a GM 4.3l V6w/an auto?  How much hp differance (if any) between the V6 and the 3RZ?

[tannji]

Just a Bump for a good thread... where are the updates?  = )  Also, where are people ordering alternate oilpans from? Am I hijacking by asking for swap part info, or should I PM people?  thanks....  and awesome swap, BTW...  I prefer 2-seat sport cars, but I am going with the same engine, and that truck is going to be a beast, I love it!

[BigMike]

Hey tannji,

I am on vacation so Bevin has decided to wait on taking his truck to the smog ref until I get back (in one more week).
Have you seen the collection of 3RZ Swaps? Check it out here: http://board.marlincrawler.com/index.php?topic=19275.0

LCOwner: The 4.3 has more power, period. Its much heavier, larger, harder to work on, worse gas mileage, etc. You should talk to Dean (4THEWKND) about this. He had a 4.3 VORTEC with a R151F Turbo 5-speed trans and he ripped it all out and put in the 3RZ. Too many headaches with the 4.3. He says he wished he had never wasted his time with the 4.3.

Power comparision:
Chevy 4.3 V6 -- 190hp @ 4600 / 250tq @ 2800
Toyota 2.7 I4 -- 150hp @ 4800 / 177tq @ 4000

So obviously the 4.3 is a much stronger engine as it well should be. If you are wondering what to put in your cruiser, then I would recommend the 4.3 because it has more power to move around your heavier cruiser, and the cruiser has plenty of engine room to work on the 4.3 as the cruiser was designed to fit a 6-cylinder engine anyhow.

If you were to Supercharge a 2.7, then I would imagine that it could make nearly as much HP, but it wouldn't have the same amount of torque at 2800 rpm because its not tuned for that..

BigMike

[tannji]

Thanks for the link... I am reading now, good stuff so far  = )

[tannji]

Bump again....  someone is either slacking, or off enjoying the truck too much to take a moment and share....  = )   
I am still rounding up info, but have decided to use the 3RZ for certain over the better revving 2RZ, with some aftermarket parts to help revs, and I am going with a drysump system from LC Engineering. I keep coming back here for updates, as this is about the only site I have found that has ANY info on swapping the 3RZ.  I am doing this with a 1971 Datsun 240Z, and will be shooting for around 400-500hp  (turboed).  As I progress, I will follow up here on this site, for those interested in the HP side of things...  and who knows, maybe some of this will eventually be applied to my 4Runner as well.

[BigMike]

8) A more recent photo. We are going to take it to the referee station in two weeks (hopefully).

Looking good Bevin!! Sure runs amazingly great too!!!
