The big bore kit is a conversion for the standard 2CV6 engine (602CC) and brings the cylinder volume to 652CC with a compression ratio of 9.0:1.
This results in more power and torque.
This kit is only suitable for original 2cv etc. engine with full 9 blade fan and all engine cooling ducting fitted. A strict regime of running in using mineral oil must be followed.
- We do not recommend fitting to:
- Any application where the engine will labour or used (as in some kit cars) without its very necessary fan assisted forced air cooling system.
- AK400 towing a trailer would be really bad, the fan must be kept at a busy speed relative to forward motion.
We do not include with the kit any larger jets for this performance improving part but you may need to increase petrol metering jets. Recommended (as a starting point) with 1982 onward carburettor (that is the Solex 26/35 CSIC - the version with 26 and 18 venturi). Primary=115, secondary=105.
