1JZGTE Age

[WindeX]

What years did they build the 1JZGTE from, most importantly what were the newest ones out of?

[Xistant]

Production started in late 1990, changed to the VVTI single in 96 or 97.......

[ReQuieM]

wasn't it '89? I'm sure i've seen JZA70's with an '89 build date. Not convo's either.

[Xistant]

meant to say mid 1990,
when they added the dark green colour also.

Changed to?

[mojo_type]

from only producing twin turbo non vvt ---> to only producing single turbo vvt

[WindeX]

Ahhhhh, thanks for the info dudes.

There are 2 gen's of the 1JZGTE.
The 2nd gen has a revised PCV? I think.
Turbo's are less prone to blowing I think.

Don't have a 1JZ so didn't memorise it, but I remember reading it on some Mk3 site.

1jz-gte started in 1990.
The "gen 2" cruz speaks of isn't really worthy of the title.. the location of a valve was changed, and valve made 1-way... that is all. Rumour has it this makes them be able to handle up to 16-17psi reliably.
The vvt-i came about in mid-late 97 from what I can tell.

a well as the single turbo and vvti it also got some extra compression

[CrUZida]

Thanks for the correction Greg.

[Draven]

moreso a clarification

[-GT-]

Sorry, so this 'update' is in the 90-97 twin turbo non vvti? Not part of the big change to single/vvti?

Any idea when this change to 'gen 1.2' occured?

Just to answer Requiem, I wouldn't take to heart the so-called 1989 imports. Before the law change there were quite a few dodgy "1989" models comming in. I once saw a 1990 JZA70 with rego papers saying it was a 1986!

The PVC valve change that that Draven is talking about was only in reference to the twin turbo non vvti 1jz. There is a website (which I don’t have handy atm) stating when the PCV valve ‘change’ happened .

Also is it just me or did JZZ30's vs JZA70's have the different PVC valve / turbo piping arrangement at the same time, I swear I have seen a same year JZZ30 and a same year JZA70 with differing configs? (That note is from my memory and maybe wrong? would someone like to clarify / correct me?). I'm suspect on the PVC effecting anything at all to be honest, it is a one way valve…
