If i were to machine a throttle body spacer, would it make any difference at all?

ok. Why would you need a throttle body spacer?

The upper plenum on the FC rx7s is already designed well enough. If you look at the placement of the TB and the room it has ...it's good. You may be able to tweak the HP levels and powerband a little bit w/ one..but you would need to make different lengths, and dyno each one..too much work for what I don't see as being much to gain.
