cylinder head

[sylvain]

hello, my name is sylvain, I live in Marseille, France, I ride in fulvia since 1980, I ride now with a 1.3 1serie fulvia coupé of 1967, I am preparing another engine, to increase compression, can i skim the cylinder head to get up 10.5 compression, or change the pistons?

Hi Sylvain,

you can find special piston for that under

With mechn. work at the head it difficult to reach 10.5 compression, maybe not possible.
Depent also on the head.There are different headvolumes/cylinder. If i remember well with
818.140 you will have standard volume ~ 24 cm³ . With 818.302 you will have ~ 28 cm³

regards

Andreas
