82 pickup 3rz Swap DD

[SqWADoosh]

Have you consulted liveoak's 3rz swap thread? He laid out the wiring pretty intricately. Though yours being a 1st gen truck I see there will have to be some differences.

[Sparkplug]

Yes. Being first gen thete is nothing to do with efi at all in the harness. I found a,pirate thread where a guy did the same.

No luck on the 3rz knowledge thread either? Maybe follow what BigMike did?

[Sparkplug]

I pretty much got it figured out. There isn't really a way around ding what I mentioned other than getting a tacoma ignition. I've read your thread. Liveoak. Redneck. And all the ones in the rz knowledge thread. It's all been very helpful

[Sparkplug]

^perfect. Been looking for one.of those. That just confirmed what I thought. And also fixes my other 2 issues with wires I didn't have spots for. I think when I get home.from.work tonight I will.be able to finalize the harness and have it ready to install now. Thanks you guys.

[Sparkplug]

I got the fuse box done. The ignition almost done. My solder but coonectors aren't lare enough to fit all 3 ignition wires tied together. I have to actually solder them myself. But I don't own a solder tool so I have to borrow one tonight from work. Other than that I have one red and blue wire off my first gen harness, I'm fairly sure is something for a gauge light or power to a gauge. The other wire is my idiot light for my charge lamp off my cluster. I do not know where I should tie this into. I haven't looked into it though on the diagrams provided by Liveoak (much appreciated by the way). I'm sure it's pretty simple tho. After those 2 wires I should be good to go as far as my harness. I still have a ways to go on tbe swap, but I qant to install my harness with no engine and apply power and ground and check things before I put the dash together and the engine in it. Just to simplify things in case of a problem. That should be this weekend.

It really is badass how helpful good forums can be as far as information and sharing. Awesome

[redneckcustoms13]

So you've built a complete harness wirh butt connectors???

[Sparkplug]

Solder butt connectors. No crimping. You insert the 2 ends. A heat it. It solders snd shrink wraps the joint all at once. They are kinda spendy, like 1.25 each. But free through work. They are awesome and def stronger than just solder.

[Sparkplug]

Got the harness done. Call me a space cadet, but I got the whole thing done and wired and taped. And then realized how the hell am I going to get this fuse box through the firewall? Lmao. I'm going to get some heat shrink bullet connectors tomorrow from work and just make all the connections in the fuse box removable. There is 8 total. They were all wired to a plug on the tacoma body harness. Unless someone has a better idea on how to do this??

[Sparkplug]

Ok. Harness is done. Pretty nicely actually I thibk. Redneck scared me about butt connectors, so I consulted 2 of the head electrical engineers at work, and they both assured me I'm fine. One actually used just butt connectors without solder on his ls1 swap into his old bronco. So I'm satisfied.

Anyways I started motor mounts today. I didn't like chilkat or the ones I've seen done online. Not my thing. Chilkat have issues with needing shim. And the stock.modified sit to close to the alternator for my liking. I plasmad off the stock mounts from my frame. I removed the stock bracket from.the 3rz. I'm going to make a plate tomorrow to the stock.mount bolt pattern to rz, and tie it with 1.75 tube to a Dom bushing with a sleeve. Basically how people do buggies. It may add a little.more vibration, it may not, but it will allow me.tons of room, a clean look, and ability to place it exactly where I want.

Now the dilemma. How to get the motor in the right spot. Logic says crankshaft needs to be center of frame. So if I just use the crankshaft bolt on front pulley as my references I should be good as far as centered. I don't know how far back to mount it or how high. I'm hoping maybe some of you have a measurement from.the front of your core support, to the front of you valve cover. Or some other sort of reference point. As far as heighth, I'm think if someone.measured their oil pan to engine block line as far as where that sits in relation to the top of the frame, that would be greatly appreciated.

[Sparkplug]

My 1st gen had a l series trans to begin with. That won't work being the w series is 4 inches longer. I also have to fab a new.crossmember at work. But he have cnc press brakes capable of doing 5/8. Gonna copy bud built design and use u bolts at the frame.

Alot of things about the 1st gens.make the swap a bit harder and more in depth. I already figured out a better way to do it next time. Don't even use a starter relay. Or the taco fuse box. Just wire to the stock fuse panel. Would be a way cleaner look. And easier. I may still do that. Not sure. I only used the taco on under the hood because that's what I saw others doing. And I only used a starter relay because I saw others doing the same. It really doesn't need one. 1st gen didn't have one. All that can really happen is they starter could get stuck on if your ignition got stuck in the start position correct? I'll keep mine now that I have it wired tho.

[Sparkplug]

Yeah that's the plan. Drop motor in. Install trans. Figure out center. Figure out where best spot for shifter is. Figure out how high I want it. Measure. Mark. And leave myself .125 of play that I can fill with weld if need be. For alignment. Then set it back in. Align best I cam. And tack everything in until I get it all done and driving. That way I cam install everything and get it all done, but still have the ability to change my.mounts if need be.

[Sparkplug]

Got the motor and trans in. Ended up reusing the stock frame mounts. Had to shorten them a bit. Worked perfect tho. I have my motor a little more forward than others ive seen. Prob .75-1 inch more forward. My ps res may hit hood. May not. Not using it either way. Was pretty simple to remount the motor actually. It's just tacked right now. Tomorrow I'm gonna brace and gusset it. Should have brake lines, furl lines, and wiring installed by the weekend. Then its just modifying my tank and clutch. Hoping to have ot driving by xmas.

[1985CRAWLER]

I don't remember reading it but did you do the t100 pan and dib stick mod yet ?

[Sparkplug]

Nope. And I don't have to till I do highsteer. My tiered clears now and moves backward under compression.

[Sparkplug]

Well I ended up moving it about .5 back. I have 4.75 jnches between my radiatior and the fan pulley. Should allow almost 2 inches in front of the fan. I started installing the wiring. I may have accidentally deleted my ac circuit. Not sure yet. Otherwise everything seems to be going good. I'm gonna finish running the wiring today and hopefully drop the tank. Plans are to modify it for a electric pump tomorrow.

[redneckcustoms13]

2nd/3rd gen 22re or 3vze tanks bolt in.

[Sparkplug]

I have 3 dif style re ranks here,  and none are even close to mounting up to the stock mounts. Making mounts for me would be harder than just plasma a hole, weld in a ring, and tap holes for the tacoma unit

Do you know the specific year and style tank thst bolts into a,1st gen shortbed? I have a few. And have tons of buddies if I can get a bolt in one.

[redneckcustoms13]

Im sorry i didnt notice yours is shortbed. My 1st gen long bed is running a reg cab 3rd gen tank.

[toyodaaddict]

90's 2wd standard cab short bed 22re trucks with the  RN80 vin  have the tank you need.  Bolts right into a first gen short bed. Carbed tanks dont work well with  efi fuel pumps. Efi tanks have a pan that holds fuel around the pickup, carbed tanks dont. When i was running a modded carbed tank, with less than 5gal of gas my engine would momentarily  cut out going around corners , do to the gas sloshing away from the pickup.  Efi tank fixed it.

[Sparkplug]

Yeah I noticed this when I modified mine. Sucks. But I'm going to have to deal with it until I can find a 2wd tank. Thanks for the info.

[Sparkplug]

Well she fired. It won't stay running. But it fires everytime its cranked. My intake is pretty ghetto right now. I didn't notice the boot got broken in the wreck also. So I tried to salvage part of it, and it didn't work too well. Pretty sure I have a huge leak right after the maf. I also don't have the exhaust hooked up at all. So no 02. And I didn't have the radiator in so there is no temp sensor input. No throttle cable also. But being it fires on start tells me everything is good to go as far as motor wiring. I'm going to start hooking things up fully tomorrow. I also lost my headlights and taillights. But I have power to the fuse panel sections inside, so it's a switch issue. Shouldn't be too hard. Also my wipers only have 1 setting now. Which is strange being I didn't touch any part of those. Could possibly be a ground issue.

All in all its coming along. I have to wait on a clutch. Thats going to be what holds me up. I'm broke at the moment because of the holidays and a aisin flywheel and clutch set is 250 bucks I don't have till the 1st. But I'll have everything ready by then to just have to stab the trans in real quick and be done. So far it has been much easier to do an engine swap than I originally thought it was going to be. I have probably 20 hrs into it at this point by myself. Not too bad.

Sorry no pics. Tapatalk refuses to work on my smart phone. It just stays at 70 percent loading pic. Sorry. Trying to figure it out.

[1985CRAWLER]

Also. From.my reading the rz water pump is chain driven? The belt is just for the fan? If this is the case, I'm going to run an efan. No ac belt. No power steering belt. No idler pulley. And just get a tiny belt to run from the crank to the alternator. Should look suuuuuper simple and clean under the hood. This may sound crazy, but I can't find a picture confirming the chain is what actually drives the pump. Can someone confirm for me?

Sorry if this is totally wrong. Let me know and I'll delete it so others don't read it and get confused.

Nice work man! That first start is always the best ! Mine did the same , would run for a sec then die , had to keep the throttle open so it would stay alive , also to answer your question the 3rz water pump isn't chain driven , it's basically the same as a 22re one , belt and pulley setup , I changed mine when I dropped my new motor in! I'm running a 22re fan with 22re shroud with 3.0 replacement 3 core aluminum rad and so far never any heating issues

[redneckcustoms13]

once you get the boot replaced it will help on the idle thing. mine slipped off one day while bouncing down a dirt rd and it was gutless and wouldnt idle except when it first fired up.

aisin clutch all the way, but an aftermarket flywheel you can get from ebay new for $65 delivered.

[Sparkplug]

Won't stay running. Not even with throttle. It fires every single time on start tho. I have power to the injectors,  and all sensors with the key in the on position. I have jumped the fuel pump to run regardless. I have water in it. I have the maf   hooked up. I do not have the cel hooked up yet. Does it need this? I also could not get my cheap obd scanner to connect so I couldn't check it fo codes. Hopefully will borrow one today. That might lead me somewhere. Does anyone have anything else to check? As far as my research, after start, the injectors are controlled by the coil packs and the maf. Correct? I do have one coil pack that broke in the wreck, it broke off the coil, the plug part did. The harness is fine. I just stuffed the broken piece in. The engine appears to fire on all 4 cylinders at start. But it doesn't run long enough to really tell. Could 1 coil pack be causing it not to stay running?  I know I don't have everything ideal at this point but you'd expect the engine to stumble and die, or run rough, not fall completely on its face. I'm 99 percent sure something isn't telling the ecu that the truck is running. So the injectors aren't firing. What says marlin guys?

[Sparkplug]

Code p1300. Ignitor circuit fault #1. Most people with thi code had the same symptom. Start and die. I think I may have found the issue. I need to get another coil pack and igniter tho. Going to see if I can source one today.

[Sparkplug]

She runs. She sounds good to . Revs great. No other codes besides shift solenoids. Pretty damn stoked I got it wired right the first try. Easy peezy. Now I just gotta finalize everything.

P1300 or p1310 is the coil not relaying the igf signal to the ecu. This causes the ecu to cut fuel to the injectors in effort to protect the engine and catalyst. This swap has taught me a ton about efi. Super fun also to do it yourself.

[Sparkplug]

Picked up a tacoma elocker rear axle with broken gears. Gonna swap 488s into it and put it in the rear. Im also building a rear tube bumper with tow package, and doing chevy 63s at the same time with new 14 inch fox emulsion shocks.

I have a elocker for the front also. Going to toss that in when I do high steer and the front axle rebuild. Also going to do ifs hubs to get closer to the taco rear axle width.

My clutch showed up today. Waiting on my flywheel and coil pack before I can progress with the engine. It's also raining and this project isn't under the car port. I'm trying to figure Tapatalk out. Really wish I could post pics. I'll figure it out

I have a fror center section and am going to be making my own crossmember from that.

[Sparkplug]

Figured pics out. This is all I got for now. Lol. I'll get more tomorrow tho. Should make the build alot more fun to read instead of just walls of text

[Sparkplug]

It stopped raining for a day. Here is how my motor sits and my clearances. Making the mounts was about as easy as can get. I took 1.5 inches out of the width and moved them back 2 inches. Bolted them to the mounts, and set them in the frame with the engine all together. Verified it was level and tacked everything in. It was super easy to adjust the position wherever you wanted it.
