My dad has 5 or so Z31 parts cars, so when I wanted to get a bigger throttle body, the Z31 unit was an obvious choice, being that its very similar to the 240SX unit, and was available to me for free. Also pictured is the spacer I had made up by my stepfather who works at a machine shop, also a freebie.

I know this is really nothin special, but I never could find anybody else using the Z31 tb on an L6, and I'm kinda proud that it was all free. Incase anyone wants to know, the ID of the TB, after the taper, is about 58 mm, on the start of the taper, I think it was 61 mm. On a side note, anyone want that turbo intake manifold?
