1JZ Variants

Different types and their native homes etc. I see JZX81 and JZX90 being thrown around alot but don't really know the differences.
Have searched the tech and conversions but there is a lot to sift through. Any links and general info would be appreciated.
Thanks in advance.

JZX81 and JZX90 are chassis codes, ie they apply to a car, not an engine. AFAIK there were no major differences between 1JZ's until the late 90's when the VVTi version was introduced, which has a completely different cylinder head and a single turbo in place of the twin turbos on earlier versions.

I was off the impression that the turbo set up was different in the JZA's? also the sumps are different.

How are the sumps different?
And these are found in Chasers and Supras? Any others?

As Norbie said, JZX are designations for a chassis type (Toyota Chaser to be exact).
There are a couple of different 1JZ configs:
1JZ-GTE (pre 1996) 2.5 litre twin CT12a turbos
1JZ-GTE (post 1996 2.5 litre single turbo with VVTi
1JZ-GE 2.5 litre, non turbo, VVTi
1JZ-FSE 2.5 litre, non turbo, direct injection (VVTi maybe)
There are also assorted sump configurations depending on the car it came out of.

Here's a snippet of info.
I have 3 1J's in my possesion, 2 supra motors and 1 chaser motor.
Early supra engines have smooth and glossy plastic cam covers and coil vents. They also have dipsticks that use a piece of cable rather than a strip of steel.
Early 1J's have serpentine belt tensioners that have "LITENS" written on them and are made in CANADA?? This model also have steel pulleys on them. Late ones have plastic idlers.

Some have a hydrolic engine fan and water pump setup and others are belt driven. I know the soarer is belt driven, not sure about others though.

there is also early and late ecus
the early has 4 plugs
each plug has 2 rows
similar to 4ag 20v style plugs
the late has 4 plugs
each plug has 4 rows
this is due to the auto ecu and
egine ecu being one unit
