I had a Weber 32 ICEV in my car and it had a separate part for throttle valve. Check out for other (bigger) Webers for similar setup.

Think about it this way: If you strip a throttle body of a 1300 Suzuki bike that redlines at 12000rpm and mount it on a 2.5l engine that only does 6000rpm you are looking at the same flow rate. I got a set of throttle bodies + injectors + FI pump for $40. And they are in mint condition. Quick question: Why does most bikes use individual TB assemblies for each cylinder while most cars use a single TB? I know how much pain it is to keep the sync on a bike right, so what is the real gain? I'm not sure which route to go with the bike. I can either make the Suzuki TB's fit (lots of pain) or simply make a manifold with injectors at the ports and a single TB at the intake of the surge tank. Will there be any real difference? How about the difference between TBI and multipoint injection? Does the fact that it is an Turbo affect the answers?
