My exact thought. The throttle body is odd as well.

Not on a Z, going in a Vq swapped car. Yes, its a fast 102mm Rep TB for LSx engines.

Still need to finish a few things before going into a dyno.

Default Ban 1cockyz

This dude never replied to me since I've sent my plenum to him. Definitely deserves a ban. Piece of 💩 Coming up on a year now since I sent my plenum to him.

I finally got a reliable supplier for flanges. The 2 people who sent me plenums they are complete and I have contacted both of them. These 3 are ready for homes.

That's 3.5"


That water line is actually not touching but that is how close the fit is


OEM like fitment

The overlap from collector to lower






Port matched



A little off the top. Been wanting to do this for a long time just to see if it works.

So you've port-matched them, do you plan to "port" them as well?

These were fairly nice casting, some of the better ones that I have worked with.

They are to the edge of the gasket. Nothing super wild. The entries was where I focused.

Installed the first one yesterday. Fitment was great, with the spacer the one coolant line on the throttle body had to eliminated.

1CockyZ, any plans of dyno tuning at this point to see what gains are possible with this mod?
