My friend has a 92 Integra GS-R. His idle is really bouncing bad and we have tried everything except replace the Throttle Position Sensor. So he went and bought a 95 Del Sol VTEC throttle body from a friend. Our problem is that the piece that runs coolant through the bottom of the throttle body is mounted on the intake manifold in the GS-R. On the Del Sol throttle body that piece is mounted to the bottom of it. So when we try to put the throttle body on the two coolant things hit each other. So we were wondering if the Crx Si throttle body will mount up to the GS-R intake manifold for temporary use. I am only asking this question because I have heard of people putting the Integra Type R throttle body on thier Crx Si intake manifold and since the B17A intake manifold resembles the Type R I was wondering if it was backward compatible.
