So it looks like my DBC Throttle body isn’t going to fit/work without a bit more fabrication on the 2.5 RS intake manifold. For one the bolt pattern doesn’t match up, and they aren’t the same size bolts either.
Plus if you look at the back of the WRX throttle body you’ll see that there is a little channel that matches up with the intake manifold to let air up into the top sensor. Of course this isn’t there on the RS manifold.
First I posted in Cribbie’s thread to see if he had an adapter plate, because it looks like he ran into the same scenario. Then I talked to Frank and we’re going to machine up an aluminum spacer
