10:8.1 pistons in Fiat 131 twincam

[Ricardo123]

Hello


I have a full new set of oversize 10:8.1 compression ratio high dome pistons I may have to use in my about to be refurbished fiat 131 2000cc twincam engine.
I am concerned about the higher compression as my engine running standard pistons at present but sadly are now worn out , hence the rebore .
I would prefer to keep engine standard but I had this set with the engine when purchased and if there work I may as well use them?
Any one gone this high on compression before ? and any issues please ?
Kind Regards
Richard

hi Richard
Did you fit those pistons as I'm looking at doing the same job as you did on my engine but have seen mixed reviews on fitting those.
