Builds An HJ61 followed me home to Texas (1 Viewer)

I would drill manifold since you have it out. It's easy. The other option is down pipe but that will give you a reading that can be a few hundred degrees cooler than the manifold.

 

[bottombracket]

Yeah, drilling the manifold makes the most sense. Who’s got a metric tap set I can borrow? (@davegonz)

 

[davegonz]

I have taps. I think most thermocouple threads are standard, not metric. Need to check that.

 

[Mr Cimarron]

What size? I have a 10mmx1.0 tap with the 9mm drill bit needed if you are going that size.

 

[davegonz]

Mine was a 1/4 or 1/8" NPT tap.

 

[MCJakeCrim]

Yeah most your EGT probes are 1/8 -27 NPT. Dropping in a lighter billet wheel than stock is about all I'm aware of what you can do without milling the compressor housing. Then if your gonna mill it, might as well drill surge flow ports. At that point your around 800 in labor if you dont do it yourself and then getting close to Gturbo peice.
There are guys buying the Mamba turbos and having descent results. I myself, would personally tear down a new mamba, retorque all the hardware, inspect quality of parts and have a shop balance it for my own piece of mind.

Numerous adapter to pick and choose your liking if you go with probe that uses compression fitting. The 10mm adapter uses 12mm & 14mm wrenches to tighten if you only want to carry tools to work on Toyota JIS hardware. NPT fitting might seal better since they are tapered.

BottomBracket,
Exhaust manifold rings and seals just arrived from Feistl over in AUS.
Sent you a PM for shipping.

Well, it’s been a little bit since I’ve done anything here.

In the past six months we sold our house in town and are in the process of moving a little bit into the countryside west of Austin. We found a place with a little bit of land, a creek for the kids to plan, and best of all a car barn. The HJ61 has been sitting half torn apart for about nine months. It’s finally time to yank this motor out and get it to Roma for a prophylactic rebuild.

I never noticed the cyclonic dust filter at the bottom of the air cleaner. Apparently no one else has, either. It was filled with 30 years of compacted dirt. I tried to get my son doing his best Andy Goldsworthy impression launching dust into the air, but this is all I could get.

Getting ready to pull this thing out.

I mean, getting ready to get ready to pull this thing out.

 

[bottombracket]

With @Unoman and @aljollano’s help the motor is almost ready to pull. Three front driveshaft bolts and it should be ready to come out.

We loaded my kids into A.J.’s 45 that he is sprucing up to sell, and drove my kids and dogs around the new property.

 

[Unoman]

Belle felt right at home knocking around the property! Let me know when you plan to hook the engine hoist to it and I'll see if I can come lend a hand.

 

[bottombracket]

Well, it only took nine months, but the drivetrain is out of the HJ61. It was surprisingly drama free to get the drivetrain up and out. Now it’s time to get moving, get the long block down to Roma and get onto the next project.

@shanko lives just down the road from me, and we are going to be removing a 12HT and dropping in a fresh one as unfortunately his motor has seized. He’s got a sweet converted FJ62 with all the fixin’s. His new motor should be here soon, so I need to roll my truck out of the way, get his in, and do this all over again.

 

[bottombracket]

Had to climb up in the rafters to put some lumber away, and I grabbed this bird’s eye view of the engine bay.

 

[bottombracket]

@shanko showed up with a 12HT on his trailer, pulling it with his awesome RHD HJ61. We then pulled his non-running 12HT truck up to the garage with his HJ61, towed my motorless HJ61 out of the car barn with my HZJ80, and finally pulled his 12HT swapped 62 off of the trailer with my 80.

Cruisers pulling cruisers towing cruisers.

We got the front ARB and winch off of his truck and soon we will get the non-running 12HT out. Teardown starts this week.

It’s hot and I’m tired.

 

[bottombracket]

The motor was all crated up, I borrowed my wife’s F350 to drag it to Fastenal, and....I couldn’t get 1000 lbs of motor into the back of the truck. Eventually I had to get a chain hoist to pick that sucker up and get it four and a half feet in the air, into the back of her truck.

Fastenal did the job and I just got this pic from @roma042987, meaning it’s about to get REAL. Looking forward to watching Roma work his magic.

 

[roma042987]

I man handled this thing off the trailer this evening and got it tucked away out of the weather and in the garage.

I know it's a little late to this party, but I would get at least a Frantz bypass filter on there. If you can find a centrifugal filter small enough that has a rotor you can take apart and clean, not a throw away rotor that costs $40+, (the scam most centrifuge makers are pushing now to create some "residual income" LOL), that would be ideal. The 2H version of this motor had one stock for a year or two in the 80s, before the dealers and who knows who else apparently yelled at Toyota to take it off.

There are other options larger than the Frantz, but I wouldn't touch any that require a proprietary element.

By the way, the latest version of the Frantz has a new tapered housing which compresses the toilet roll over a good part of its length. The purpose of that is to get around the ever-cheapening toilet rolls and their air gaps between the layers of paper.

....you guys are making me want to move to Texas.
