BigMike's Big Project

[Skinny_Pedal]

thats all! we were all waiting for u to post something spectacular and thats all! im j/p sounds like another long day. keep up the good work

[BigMike]

Oh I forgot to mention that I put the hood back on and it clears the top of the powersteering resivor. I got my hand up in there with the hood down, and there's gotta be at least 2.5" between the two. So the engine is resting at a pretty low spot, I would say, which is just what I wanted I also noticed that the hood doesnt line up well with the passengers fender.. Im tired of owning vehicles that have body problems. Oh well thats life. I know I'll be beating the crap out of the rig later on, but it would be nice to see things in good condition, you know?

Night,

my local junk yard doesnt ask what car it was off of they  have a list of parts and prices posted inside and its the same price no matter what the vehicle is it could be a break drum off of a friggin semi and it would be the same price as a rear yota drum there all the same

That is so they can charge more and just say "we charge a flat rate"

Thursday,

Work, work, and more work = Fun, fun, and more fun. Put in a second night in a row on nothing but wiring, and I now have the interior T100 wires all sorted out. I've gotten to the point where I can't get any more progress until I get the FSM for the T100..

Mike,
I have a FSM (5" thick) for the `96 Taco...if you want I will get you pics out of it.

We actually have a 2000 Tacoma book but that newer 3RZ uses 4 coils (direct fire). My buddie came by the shop last weekend and I checked out his 98 Tacoma 3RZ and it had two coils (DIS twin, just like my 91-93 4A-GZE engine in my MR2). So those are all very different from mine. I dont know about your 96 book, but I dont need any info for the engine harness. It is very simple and I've already got the battery/alternator fuse box 100% figured out without any diagrams. Instead, what I really need, is the interior diagrams for the T100, which is different from the Tacoma interior.

And this is excatly where I am at with this conversion, the interior wiring harness. When I did my wiring on my MR2, the conversion came from a FWD Corolla. The corolla mounted the ecu in the cabin, so its ecu harness had everything from dome light wires to blower fan motor to electric mirror wires. I didnt have the diagrams for the cabin, so I just cut back the wires and left them in the loom. Well that is not going to happen with my truck. Once I get the FSM, I plan to remove EVERY single wire from the interior T100 harness and remove ALL wires that are not related to the engine. I know this will take a couple more days or so, but I want to cut out all the :bull crap: T100 wires that I dont need and keep every thing as simple as possible.

So that's where I am at. Oh, I traced out the sensor lamp...

hey, what's the "sensor" light on your gauge cluster do?  that's almost the exact same cluster as my '79(besides the idiot lights having different having words instead of pictures) but it sure doesn't have a "sensor" light

...which serves the '81 as both an exhaust over-temp warning light and a service interval light. I will be using this lamp for the (temporary) Check Engine light. And I already found the purple wire from the ECU for the Check Engine light, so the check engine light issue is already water under the bridge.

Welp, Im looking forward to this weekend as I hope to finish all of the wiring completely and then focus on the few remaining mechanical things after which it should be about ready to fire up

Regards,
BigMike

kool project!!!! wish i had that motor

[yotaboy79]

my local junk yard doesnt ask what car it was off of they  have a list of parts and prices posted inside and its the same price no matter what the vehicle is it could be a break drum off of a friggin semi and it would be the same price as a rear yota drum there all the same

That is so they can charge more and just say "we charge a flat rate"

actualy they are cheap rear springs off of any vehicle are 30 bucks a pair

[kyle_22r]

wow, that's pretty wierd about the sensor light.  i didn't even have something that sophisticated on my '84!

and we have a junkyard around here with a price list on the wall.  not bad(22Rs cost $199) but the only problem is that the place is so cheap, you can't ever find anything!

[yotaboy79]

yeah about the junk yard i go to you never see a fwd toy out there and i found an 83 practicly stole an axle shaft with the whole brake assembley on it for 20 bucks

[kyle_22r]

i found a '87ish toy 4x4 in my favorite junkyard yesterday(a different one).  no engine, but the tranny was still there.  looked like a w56.  i woulda grabbed it, but i have no money

[freds40]

Out of curiosity, what will the clearances be with hy-steer and the oilpan on this motor? The motor wasn't in the other day I was over so I figured I'd ask.

[donkeykong]

I didnt say you couldnt get a good deal.  My dad got a complete in-cabe cage for $50.  It had not been welded together in the truck just sliped into place.  Fit his 80 perfectly

[supratruck]

Big Mike

Did you ever get that wiring info that you needed?

I couldn't remember what year you needed it for but the local Toyota dealership has TSRMs And EWDs for '93 and '94 T100s that I can borrow and scan.

Saturday - Monday, Updates!

Over the weekend I caught the "lazy" sickness along with a raging headache that kept me at home all half of sat. and all day on sunday. So I took all of the T100's interior wiring to my house thinking I would figure it out there, yeah right. The only wiring diagrams I have are from a Alldata computer system next door to our shop and it sucks. I looked at some haynes at Autozone and its the same crappy diagrams. So I have no choice now but to put the wiring off until this upcoming weekend; I've ordered the Factory Wiring Diagram book and it will be here in 4 days

So the weekend was pretty much a wash. Nothing happened at all.

Well, Today, Monday, FINALLY the ECU and the 2nd o2 sensor came in the mail. That's good news boy!

Here are some pics from Saturday of what my cabin looks like right now and the 'humongus' Mitchell electrical book for all imports from 79-86, of which only TWO pages are for the wiring on the '81.

[BigMike]

So this evening I finished with the clutch (just need to bleed it) and tried to finish the fuel lines when I tragically discovered that all of the lines that I had nicely routed are two small. I think I ordered some 5/8" when I need 3/4" line.. I'll have to check tomorrow. So that majorly sucks because I've already spent a pervious evening doing nothing but getting most of those lines installed and it was looking really professional. But atleast now I've got some great templates so it's not a total loss.

So after spending about an hour before I discovered the lines were wrong, I decided to get working on the Turbo radiator. I sent it to the rad. shop last Fri to get it pressure checked and cleaned and the guy told me it was in great shape and didnt need much cleaning at all. Kick ass!

I picked it up after work this evening and had it ready to be pre fitted. But first I decided to compare it to the stock '81 radiator first...

[WHITE_TRASH]

5/8"! 3/4"!  What the heck are putting in that thing a 900" Donovan?  Im guessing that you ordered 3/16" but needed 5/16"?  I sorta did the same thing, I bought 3/8" but needed 5/16"

[BigMike]

[BigMike]

Im guessing that you ordered 3/16" but needed 5/16"?

Yeah, that sounds better

As you can see the Turbo Rad (3 core) is massive compared to the carb radiator.

Here are some dimensions:

	1981 22R	1986-87 22R-TE
Core Height	15"	17"
Core Width	21"	21"
Core Thickness	1.25"	2"
Volume	393 cubics	714 cubics

Man that extra core really makes a difference! It is 1.8 times larger than the 2 core. I'm thinking that cooling wont be a problem here

The golden question, "But Mike, will it fit??"

With some minor grinding I am happy to say that that's a big ten four zulu milkshake underwear! Notice in the 2nd pic where the added 3" in height is in relation to the '81 fan shroud. It needs to be "slightly" ground to fit within the frame rails.

[BigMike]

And my luck continues!

[BigMike]

As you can see in the above pic, the height is the same as the stock 2 core radiator so this is an easy upgrade by far!

Here is my clearance for the clutch fan and also a pic that shows how nice the extra height of the radiator fills up the entire frontal area below the grill 8)

[BigMike]

Now the job (only with the 3RZ swap) runs into a couple problems..

I know its hard to see from the above pic, but there seems to be ample space for the fan.. However the stock 3RZ fan does NOT fit. It could fit, but you would have to install the fan first, and then put the radiator in. And then even still it would be pretty darn close to the fins of the radiator.

You can see from the following pictures just how massive the 3RZ fan is compared to the 22R fan:

[BigMike]

But get this, the 3RZ fan almost bolts directly onto the 22R clutch!!!!!!!!!!!!!!!!!!!!!! Can you believe it? All that is needed is to drill some new holes and it will bolt right on. Also it self centers around the clutch so it should be well balanced!

But, after doing all this work, Now the fan sits to close to the engine and the blades are interfering with the belts and pulleys. So it's either to long (stock 3RZ clutch fan) or its to short (hybrid 22R/3RZ clutch fan). I really really wanted to use the larger fan to pull more air flow, and maybe I will come back to this later down the road, but for now I've just decided to keep it simple and just use the good ol' '81 clutch fan.

Now for the more keen eyed readers, you might have noticed from one of the previous pictures that the 3RZ clutch has larger bolt holes than the 22R clutch fan. This is because the 3RZ's water pump uses 8mm studs as apposed to the 6mm studs on the 22R water pump. So, with my good luck continuing, I checked the bolt pattern (of course this was one of the first things I did) and to my surprise it was the same distance and the back side had the same stepping and depth and it is a direct bolt on once the holes are drilled out to the larger studs.

[BigMike]

Here is a pic of the 22R clutch installed onto the 3RZ after drilling out the holes. The stock 22R fan goes right on and there is plenty of room for the fan!

I didnt have time to play with the shroud. I'll let you know how that goes tomorrow night. It was getting pretty late by this time, and I knew that Marlin was getting tired when he began singing along to Blondie songs on our classic rock station

[BigMike]

And finally, as if this evening couldn't have gotten any better, it turns out that the stock T100 radiator hoses are a direct 100% bolt in

So I got alot done tonight and Im feel'n pretty good thus far. Tomorrow I will finish up with the radiator, order the correct fuel lines and finish those lines, and then start on the exhaust system I think.. I need to buy some pipe and get a muffler and cat. Hmmm. Might take a couple of days on that.

hmmmmm... what's left Oh, I need to clean up the underside of the hood and get it painted...... hmmmmmm ah, I need to get the power steering cooler installed now that I got the radiator in. I'll see if I can get around to that tomorrow. Also I've got an oil cooler and filter relocater kit, so it looks like I'll be busy again tomorrow night.

Hopefully I will get the factory wiring book by Friday so I can have something to do this weekend. Hopefully I can get it 100% finished by friday except for the wiring. Also, the gas tank should be here by the end of the week so I'll need to get that mounted. One more thing is that I am not going to mount the battery in the engine compartment. I want to lower the CG as much as possible, so I will mount the battery beneath the bed. It will also help with weight distribution. That should be easy to do so Im not panicking about that job.

That's it for now, Night!

[Skinny_Pedal]

o man if i heard any old guys singing along to blondie, it is time to get the hell out! lol. looks good, im liking that turbo radiator!

[donkeykong]

It is coming along amazing...looking real clean

[84runner]

I just wanted to say how envious I am of this engine swap and to let you know BigMike ,YOU SUCK    I'm gald this is falling together for ya and not falling apart.

[yotaboy79]

 

[brainlessfool]

And just what is wrong with singing along with Blondie? 

I like the trubo rad! gives me    for the next time my 83 need cooling help. do you think there enuf room for a small elet. fan behind and one in front of the rad?

[Skinny_Pedal]
