Hi,
I am building a Giulia 1600 Sprint (-62) according to FIA App K rules and hence need to stay with the standard Inlet+Exhaust manifold, which means breathing restriction even with a Weber DCD 36/36.
So, to get the most out of it I try to source as good high compression ratio pistons as possible, without getting too bad piston shape.
Question: Can anyone share experience and recommend any particular piston?
-
I have found some decent alternatives. These are from Alfaholics (UK), Classic Alfa (UK) and OKP (D). All are on the low end on target CR and none have all the benefits combined in one piston - at least not as I see it in the perspective of maximum performance from a Normale engine.
