Theres a nova in this months TV with a C20XE on twin 45s. They look similar to what i thought was throttle bodies on the same engine (different car) at PV2003.

Cheers.

twin carbs serves 2 cylinders each, throttle bodies serve each cylinder separate..........i think..

quite the opposite, an aftermarket mappable ecu runs tbs far better than a chip etc, a worth while upgrade for the remapablility with a laptop!

As said above.

Also, with TB u set it up once and once 've got it right ur sorted. PLus u can get more power gains with Throttle bodies and a decent engine managment system.

Carbs need to be re-setup all the time. Pain in the arse. Can't sqeeze as much power as throttle bodies.
