FS: S3 Caterham 7 with 2.3L Cosworth CSR

Recommended Posts

With a toddler and a newborn on the way, it is with a heavy heart that I must sell my beloved 7. It started life with a Zetec SVT engine then I swapped it out in 2016 with a full on CSR260 Cosworth motor including the bespoke CSR dry sump system. It is quite a unique combo as there are not many S3 with this setup. This car is very light with an incredible power to weight ratio, it tipped the scales at 1180 pounds wet. It was built to be a quick and reliable car for canyon carving and track. It addresses both fuel and oil starvation with the fuel swirl pot and dry sump system to be as reliable as possible. Suspension is fully adjustable with 3 way coilovers (low, high, rebound) along with adjustable front and rear sway bars. No need to ever smog as it is exempt with clean California title. The telepathic handling as well as the screaming ITB’s are toxic, nothing drives like a 7… nothing. Kinks have been worked out, it is turn key and ready to go. Below are the specs and options:
