Converting a duratec SV from single throttle body to Jenvey ITB's

[Drakman]

Hello Guys and Girls,

 

I am going through the process of converting my 2014 Caterham Roadsport 175 to Jenvey itb's.  I have contacted a couple of people including Jenvey themselves about the purchase of an ITB setup to suit my car.  

Some suggest 48 mm, others 45 mm, some with the electronic accelerator actuator and one suggesting converting to a cable.  The car is standard with Drive By Wire.

 

Can anyone here  help me with the most appropriate option for a mainly road going car.  45 mm or 48 mm?   Cable actuated or electronic Drive By Wire?  Pros and Cons of either setup?

 

Thanks in advance.

Dave
