Time: spent two hours going through all of the new OEM parts I’ve bought for about 2.5 years waiting for building this engine and doing the swap.

Since the engine is so awesome inside, I’ll probably not need about 1/2 of these parts.

Engine swaps aren’t easy; throwing s*** together just produces s***, or some sense of “acceptability” which is basically short-term gratification.

Planning for a engine swap takes hours of thought, lists upon lists of part numbers and then long hours of research; readings in technical aspects of power plants and drivelines; measuring, testing, and then system integration. All of this takes long amounts of time.

In any event, I’ll have a lot of 1HX series engine parts for sale soon. 😂😂

😳

I have a lot of spares but you have a LOOOOTTTT of spares.
 
Engine Gasket Kit
First part you always order is your OEM main engine gasket kit. Without it you are relying on a conglomeration of parts sourced globally.

Made in Japan is always my first direction for these important components. Toyotas suppliers have been doing this for a long time; they know what the call is.

Hardware
I can’t stand zinc colored bolts on any exterior of a Toyota engine.

Gaudy as ****all and looks like Trump’s Manhattan apartment.

I’m silver and black attack always. So anything on the exterior that’s ugly zinc/gold/blah will get replaced with current silver bolts.

Bag all that gold sh1t up and I’ll buy it from ya. I need hardware. Like I don’t have enough of it in little baggies everywhere.
 
Even if it’s the wrong color?😉

I want to get a Caswell plating system but I’m already three projects behind your 60, and I can’t possibly get any slower.
 
Engine Parts
Working on your own junk is slow and tedious. Most days I want to be outside or hanging out with friends.

So, this might go a bit slower than other folks’ builds.

PS Pump I’ll be using:

Kuzeh and Fuji Bellows have historically been the OEM for Land Cruiser engines.

In this instance, Kuzeh Thermo Products is the OEM since they specialize in wax-type thermostats.

You can read about their history and business here:

Main block assembly was cast and machined on 1/16/1991 by the Toyoda Industries Corporation. They have historically cast and machined engines over 3.0L for commercial vehicle application. All forklift engines are manufactured by Toyoda Industries.

Just a couple of days later, the main bearing cap was cast and machined:

The gaskets are 15785-66010 which are actually utilized for the 1FZ family of engines first. A good example of part number reduction by sharing or parts.

Installed with oil filter spill catch and temp switch.

Oil Pressue Sender
Oil pressure sender assembly. Manufactured by Yazaki Corporation. Yazaki designs and manufactures almost all of the “sensing” and meter-based sending unit for the Land Cruiser line. One of Toyota’s oldest suppliers. They also design and manufacture the wiring harnesses in all Land Cruisers as well as your gauge cluster and meters themselves.

Onur, how about an update? The first day of summer is just around the corner now and you must be itching to get out in the summer breeze with that soft top.
