I have one. You can ask me anything or go to spyderchat.com for all sorts of useful info.

** No one has said it yet, but the 1ZZ has a timing chain. No maintenance schedule for that but check it at 120K!

You just don't know how to interpret them, that's all.

It's iteration, followed by block code, followed by a dash, followed by the "options".

Options that I know off the top of my head: E - EFI F - narrow angle DOHC (economy) G - wide angle DOHC (performance) T - Turbo Z - Supercharged C - Cali emissions

There's a code for Japanese emissions that I never remember and another one that used to be used for transverse mounting but was deprecated.

So, 22R-E is the 22nd iteration of the R block using electronic fuel injection, where the 18R-G is the 18th iteration of the R-block using a performance oriented DOHC head.

It's pretty much exactly the same as Nissan, except Nissan goes one further and instead of iteration uses the displacement in deciliters, uses "D" for DOHC, and uses a T for every turbo (i.e. RB26DETT is a RB block displacing 2.6L using a DOHC head with EFI and twin turbos, a VQ35DE is a VQ block displacing 3.5L with DOHC heads and EFI)

Ugh. Want. Add another one to the short list.

Thanks for clarifying that, I never understood why a 22re was 2.4 liters, now I get it.

Dr.Linda's Europa is getting a 1nzfte and a c50 trans.

And "Z" in the motor designation means that the letter before it has been reused. So, for example, a RZ block is different than an R block, but the Z does not in this case designate a Zupercharger, just a different block. Now, a 1RZFZE would, theoretically, be a 1st iteration of the RZ block with a fuel efficient scissor cam head (2 cams but one drive pulley, 2nd cam is driven off the 1st), with a Zupercharger and fuel injection.

what i was going to say was i thought the z was a supercharger (belt driven) and t was a turbo? a la 7m-gte? or 2jz-gte? and 2gr-fze for the evora, where the z is the super. and I think the mr2 sc was the same way.

Correct, but only on the second half of the nomenclature.

Yeah, the dash is important in the Toyota nomenclature for the above reason. 2JZ-GE is not supercharged, but a 2J-GZE would be (I have no idea what a "J" motor is or if it even exists, this is just for example).
