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

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.

"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.
