I thought it might be a good idea to put together a list here for 1JZ tech info and places to get 1JZ parts

I'll start off with what little i have. Send me a PM with what you have and i'll add it to the list. They don't have to be the best places. But just to have what is out there so people can get an idea of there own.

Some of this i took from other sites info pages. some i found on my own but i am sure someone has mentioned it somewhere....lol

Some information tidbits


Alternator replacment


This was taken froma post by HamsMKIII on another forum

I noticed many references to the MKIV alternator being a direct swap into the 1JZ. It isn't really a direct swap since the plugs on the alternator are different. I accidentally broke my alternator playing around with it (don't ask), so I did a little research on a replacement. Oddly enough, the alternator from a 1992-1994 SC300 only, not 400, is a direct replacement for the 1JZ. It's a perfect fit, and the plugs are identical, so there's no cutting involved. Just plug and play. The best part? The SC300 alternator is a 110 amp alternator. Oh and another great part? I paid $130 with tax for it, lifetime warranty from Lexus. How about that? Funny that the Lexus part ended up being cheaper than the Toyota part. Anyhow, I thought I'd pass along my experience in finding a direct swap for the 1JZ alternator.

- Hams.

This is also from a poster on another forum

OB1 JZA70

"Ok... I have a rare engine... where do I get parts in North America???

I have seen many people asking one of two questions:

A. Where can I get parts for my 1JZ?

B. What parts are interchangable between the 1JZ and the 7M or 2JZ?

I have posted the following list a couple of times on various forums but I figured I should finally post it someplace permanent. So here you go... this is what is interchangable between the 3 engines... the 7M, the 1JZ-GTE, and the 2JZ-GTE. Also below I have added where you can source a few of the other common parts for the 1JZ engine. Anyone who sees errors or has additions please contact me and I will keep this list up to date.

Common parts between the 7M and 1JZ
- Clutch kits (but not flywheel)
- Cat back Exhausts
- 89+ motor mounts (rubber part)
- Anything trans (R154) related
- Anything gauge related
- Rad (if you're not using the 1J hydro fan setup)
- Driveshaft/Diff

Common parts between the 2JZ and 1JZ
- Power steering pump
- Alternator
- Spark plugs (ngk 3330 and 6097)
- US spec 550cc injectors (resistor pack needed)
- JDM Spec 440cc injectors (drop in upgrade)
- Water Pump (requires removal of the 1J hydro fan and a 2J pulley)
- Head gasket (although most other gaskets do not swap, get a 1J set to do it right)
- Clutch fan (if you use a MKIV water pump and pulley)
- Serpentine belt (but NOT timing belt - see below)
- Oil filter and relocation kits
- Intercooler kits
- Plug coils
- Cam gears (incl aftermarket adjustable)
- JDM 2JZ Map sensor
- Ignitor
(edit: some more added info)
1) The rod and main bearings.
2) The head bolts, crank and rod bolts from stock or ARP either bolts or studs w/nuts.
3) The pistons including the wrist pins, wrings and locks.
4) The head gasket, stock or aftermarket.
5) stock side feed or after market side feed high ohm injectors. Low ohm injectors require wiring in the 7M or preferably 2JZ injector resistor pack.
6) Water pump and housing when replacing the hydro fan to electric or clutch fan.
7) Cams are normally not interchangeable with out some grinding on the 2JZ cam and having it spun balanced, HKS, Jun and Blitz all make 256, 264, and 272 cams for the 1JZ.
8) Cam shims, springs, retainers, Valves and springs, along with buckets are interchangeable.
9) turbos are not directly interchangeable and require a degree of machining to swap out the 12As for 12b.
The list will be updated as I remember and acquire more info.

(my edit: i am not sure about this timing belt) has been confirmed bellow by a member that this does work Oct-21-2006
For a 1JZ timing belt:

The 1988+ Isuzu Trooper 4 cylinder 2.6 liter engine (4ZEL) uses the same belt as the Toyota 1JZ engine. So instead of getting a belt from Japan (~$100) you can pick up an Isuzu Trooper belt locally at an auto parts store for about $30 US. Make Sure You Get The 4 Cylinder 2.6 Litre Engine Belt!

Timing belt specs: 137 teeth, 25mm wide

For an aftermarket flywheel:

Order a 7M fly but have the 2J bolt pattern drilled into it.

Very general rule of thumb:

From the Clutch/Trans back it's a regular MKIII Supra (save for the Torsen diffs) From the FlyWheel/Bellhousing forward, it's 70% 1J / 30% 2J parts.

Great list.

I am running the Isuzu timing belt from Napa. It works just fine.

Can someone confirm this? 2JZ valve stem seals should be the same.

I've got Front and Rear main seals sitting at home. I will post part numbers up this afternoon when I get home. You should link to Champion/Jay Marks Toyota in Houston...they stock many 1JZ Genuine Toyota parts (that's where I got the seals from).

Ok guys.

Front Crank Seal: 90311-46001

Rear Main Seal: 90311-90006

I also have Valve Cover gaskets and Camshaft Seals on order. They had run out of their stock (they normally have them, Champion Toyota that is). FYI if they don't have the part they have a 10 week lead time for parts from Japan.

P.S. I don't think it can be stressed enough what a great asset Champion Toyota is to the 1JZ community. Recently JDM parts have become very hard for American Toyota dealers to aquire (I'll have to tell you the story for why that is...the guys at Club4ag weren't too happy w/ me for that one). So, even though I am a Service Manager at a Toyota dealer, they can still get parts that I can't get through my own parts department. If you guys have any want/need for parts that aren't available in America, they are just a phone call away and the worst they can say is no. They are great guys w/ great resources.

I've decided to let it go this time. I don't drive it much anymore! I use my brothers car to drive to school and take the bus to work. And I don't drive much on the weekends!


I'm gonna list some of the stuff for the car for sale. (HKS DP, MK4 wheels, Blitz BOV, turn signal covers).

want anything!?

Damn you, I would have bought it had I known that you would have sold it for real. I could have bought it instead of the clip I just bought. :icon_mad:

Buy some sawblades & sell me your wheels. You'll get more money that way, and sell it quicker too...

take it to PM.....

I need the specs on the 1jz head. I actually need the valve clearances and tolerances for the machine shop that has my head. I have the Rick 92 site, but it won't let me pull up half of the pages because of a bad encrypt dictionary. I've tried to upload Adobe 8.0, but it won't connect to the server............. ..........Thanks

I typed this in another thread as well. I need the answer by tomorrow if possible. I know you have the answer somewhere Josh...............:biglaugh:

There wasn't anything in any of the things she printed off about the cam specs or the valve tolerances. If anyone has these please let me know. Thanks.

another option to the throttle cable is one from the '92-'96 4-cylinder Camry. They are cheap and super abundant at junkyards. I am using that on my Cressida and it's perfect length.

Also many have used it on the MK3 with similar results.

quick question, does anyone know if the electric waterpump for a 2jz will work on a 1jz swap? they sell them on titan and it says that i wont work on the jdm 2jz but it doesnt say anything about the american version so...... if you can use the 2jz water pump on a 1jz then shouldnt you be able to use the electric one too?
