You want one with removable dies. Ebay is full of knock offs. I have one that works pretty well. Looks like this one. The real deal will cost a few hundred bucks, but these ones will do the job for a hobbyist.

Yeah I was looking at that one. I may just order that now. And definitely don't want to pay hundreds for a few time use.

Noise filter aka capacitor.
I was reading something about it being for the radio? It connected to the 7m harness. Is that what helps reduce radio issues/disturbance due to the alternator?

Also I did order that crimping tool you recommended to me. Can't wait to get it.

yeah, it gets rid of alternator whine on the radio and filters out noise from other things like the ignitor and injectors. its a very simple low pass filter.

Ok so started working on wiring the 1jz harness to plug into the supra body harness. Ive been following this thread but I have already found a couple mistakes.


Only reason I found a couple mistakes is because I'm also following these pinouts diagrams


And


Sadly I was tring my best not to cut into the 7m harness or cut any more into the 1jz harness but I had to :(. Oh well, will get this done one way or another.

Man my harness is so close to being done but I'm at a stand still. Few wires I'm trying to figure out then I got to loom it all up. Once that's done then I'll put the harness on the engine and finally drop the engine in the supra.

I still have to get an intercooler piping set and get all the tuneup for the engine (spark plugs, oil and filter, air filter, coolant, tranny fluid, diff fluid, and new gas as the current gas has been in the tank for about a year)

May also have to get a new battery. Also got to fix the 1jz power steering hose to the old 7m hose as I want to keep the power steering vacuum valve. So much to due yet so close to getting it started.

Just got in the old style starter connector in today and swap it out with the new style connector. You have to do this to be able to use the 7m starter. The new style is the black and the old style is the white. I ordered a few plugs from wiringspecialties.com including this one. Im actually really impressed with their services and their products.

And again i really want to thank pi for the crimper recommendation. This crimper is really good. Ive already done the injector connector pins and this starter connect pin with this crimper. Worth the $30

Looking good
Appreciate it. It should look much better once I get the loom on. I only taped it up for compressing the wires together tighter for better concealment. And also for looks on the parts of the harness I will not be looming.

looks great. What tape did you end up using?
Appreciate it pi.
I used electrical tape from home depot. I know it wasn't a good tape to use but I also did decide to use a split loom on top of that. Just waiting on it right now. They just shipped it out yesterday.

I had a couple questions pop up in my head about basic maintenance for the 1jz. Some of these questions are just for future references and some are for current references.

1. Oil filter, are they the same for the 1jz, 2jz, 7m, and 1g engines?
2. Oil, what is the capacity for the 1jz and the factory recommended weigh?
3. Fuel, my guess is anything over 90 octane?
4. Coolant, toyota pink coolant is best?
5. Power steering fluid, what is factory recommended for the 1jz? Same as 2jz?
6. Brake fluid, would it be practical to switch to dot 4 or should I stick with dot 3?
7. Transmission(R154) and differential(stock turbo) fluid, if i remember right they both
use the same velocity gear oil correct?
8. Spark plugs, what is factory recommended for the 1jz? Same as the 2jz?
9. Serpentine belt, can these be purchased at any local auto parts store (autozone, advance, oriellys, napa) for the 1jz? I will be keeping a/c and power steering so stock belt size.
10. Timing belt, is the 1jz belt the same size as the 2jz?

Finally dropped the engine in today with the help of my brothers. I will be only looming the part of the harness that will run along the firewall so I figured might as well drop the engine in. Fitment was really tight to drop it in but it's in. One thing I did notice was the TB cable mount will have to be modified to line up with the TB cable mounting point.

I'm may have a clearance issue. This isn't a fan and clutch from a 1jz or 2jz. I measured this fan and clutch at 4 inches. Then I measured my brothers sc300 fan and clutch at 3 inches. Ill have to grab me a sc300 fan and clutch.

Actually the battery will fit perfectly. Pre-mapped everything out.

And I do appreciate it speedy. Yeah it is a time consuming thing to get everything in right and working while looking nice.

Ok removed the fan and clutch. I think this may be the lexus ls clutch and 7m fan blade set up. Very thick. Will be getting the 2jz fan and clutch.

Also put some of the body panels back on today.

Thanks man, I really do appreciate it!

Nah, I want this to look as stock as possible. The only things that won't look stock is the radiator, intake, and intercooler pipings.

Needs y'alls suggestions on the power steering reservoir placement. I have two photos of where I was thinking. Im more leaning towards the first photo as there isn't much going on there and I have many available bolt holes there. The second picture is closer to the pump but there is some much compacted there and not very many bolt holes available. Let me know what yall think.

Second picture is closer to where it actually was on the JZA70's. If i remember correctly one of the 2jz or MKIV reservoirs mount very similar to the actual 1jz reservoir.

Edit - Also seem to recall the 7m-ge reservoir being easier to adapt for this. Or needing less of a bracket made; either one requires some creativity.

Yeah I was getting ready to measure to make a bracket to mount it there (aka original jza70 location) then realized the area the cruise control sits is pretty free so now considering mounting it there. Im pretty sure the extra length in the hose wouldn't really affect the preformance.

Was trying to pinch a penny and reuse the 7m reservoir. Seen it done before on other 1jz swaps.

Definitely has been done, and the extra hose wont matter. And even though i used the original JZA70 reservoir it still is a tight fit with the hoses as you mentioned before, theres even an S like bend in the big one iirc.

Ok got the ac lines hooked up to the ac compressor. I will have to remove the power steering pump every time ill need to work on the compressor but that is fine.

Ran the heater hoses as well.

Also ran the brake booster hose

Also here is my plan of action for the power steering pressure line. Hopefully it can hold the pressure.

Yeah to handle those pressures you will need a reinforced crimp like the OEM ends have.
