Improved valve springs for Alfa 159 tbi
My Tbi have 265hp and 400nm. (Stage 2 with downpipe, free flow big intercooler and etc)
I have also placed Colombo&bariani camshafts (see the link) - https://www.gazzellaracing.com/produ...roductid=17908
I now want to go for a bigger turbo, I was thinking on the precision 5130B. But I would like to replace the valve springs first.
Do you have a recommendation for an improved valve springs from somewhere? I can't find them anywhere.
Thanks in advanced for the help 🙏🏻
