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.
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!
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.
If it's not on the above lists... assume the part to be unique to the 1JZ. If you find a 1JZ part that is interchangable, or can be sourced elsewhere and is not on this list please contact me and I will add the information to this page.
