H22 TB with Turbocharged B-series
If you're using a Skunk2 manifold with GM 3-bar MAP sensor, you may want to consider using an OBD-1 H22 throttle body.
The outlet to the manifold is 62mm. Saves you the trouble of overboring the throttle body to the same size as the Skunk2 manifold.
If you get an OBD-1 unit, you retain the FITV and the fast idle function if you convert from OBD-2 to OBD-1. Beats trying to find an ITR throttle body with the FITV for a good price. I've seen the OBD-1 H22A TB's selling for $60 to $70 (w/o sensors)...roughly the same as GS-R TB's ($100 with sensors).
Uses an externally mounted MAP sensor. Makes it easier for you to connect to the GM 3-bar MAP sensor.
The throttle pulley looks interchangeable and the throttle stops are in the same position as the GS-R and PR3 TB's, so swapping the throttle rotors to use it on the Skunk2 manifold doesn't look to be a problem.
Seems like a no-brainer to me. Please tell me I'm not the first person to consider this.
