Stock and performance parts that can be used on 1JZs originally designed for the 2JZ
Here are a list of something that I have been asked if they are interchangeable on the 1JZ from the 2JZ:
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.
