haha fun stuff. You buy the TB and send it along with the switch to me and I can take care of the mounting of it for you when the time comes

I'd love to do a nice custom ITB setup on my motor here as well but it's cost that's holding me back.. The subie engine already uses twin 49mm TB's and a split plenum setup with what they call an iris valve to control plenum balance between both halves of the motor. All so complicated.
