I'm looking to fit ITB's to my 2015 Caterham 7 420R SV (Duratec engine). The Caterham roller barrel throttle bodies are seriously pricey at 4K. Now I'm new to the caterham world, but in the past have modified other cars and know they ITB's are usually around 2k.
I would be interested to hear other owners feedback on the caterham RBTB's and if they believe it was worth the 4K. Then I would also be interested to hear if anyone sourced ITB's elsewhere?
