What year model Q45 Throttle bodies fit Rb25 Greddy plenums?

Searching google shows differences.

Which ever is 90mm or are they both???? I have one setup the same way... but didn't know there was a choice!

If only one is water cooled then thats the one I have (the left one) ... the one on the right doesn't seem to have the cooling part.... well that I can notice in that picture...

Do they not both fit? Was there a major design change ?

From what I heard there is two types but both are 80mm butterflies, one just has a bigger mouth (I think it's off the earlier range).

Don't know this 100% for certain but it's a start

Mine is the one on the right.

The one on the left is from a 96 Infiniti, the right is from a 90 model.

The pics below are from a 91 model.

It's still a 90mm (80mm butterfly) Q45 TB.
