Joz is going to be fitting individual throttle bodies on his 5efe soon. Isn't easy though, as a lot of work to make the setup, plus obviously need proper management as the air/fuel ratios need to be right as with throttle bodies a lot more air will be getting into the engine. Overall, isn't cheap, although not sure on what gains will be achieved, because as far as I know Joz will be one of the first people to have it done. (plus you will need to have supporting mods to make the most of it - exhaust mani and exhuast etc)
