I'm planning to build injection in an engine that originally uses two SU HS6 carbs. At first i planned to use the carbs themself as throttle bodies, but they're rather worn out, and they don't have throttle position sensors on them. Considering the vast amount of different throttle bodies out there, there must be one or more throttle bodies that fit a manifold that is meant for HS6 carbs.
HS6's have four mounting holes in a square, 54mm apart from each other. The bore of the carb is 45mm, but that doesn't matter that much. The original carbs have mounts between them and the manifold. The dimensions of that mount are displayed in the picture below, you can derive the dimensions from that drawing. The three holes around the carbs are to bolt this mount to the manifold. Anyone who knows a throttle body that fits, or nearly fits these specs?
EDIT: This application is for a TR7 with 2L 4-cyl. (Info added by Pᴀᴜʟsᴛᴇʀ2)
