There has to be a comp ratio difference between the two engines anyone know the ratios and whether it is in the head or the piston to get the change ? thanks

my thoughts are if in the piston and I wanna raise compression with lpg to reduce turbo lag use either normal pistons or normal block and retain heads - in the future maybe !!

The reduction is in the piston

Just for another confirmation it is in the pistons, theres a hollowed out section. Comp ratio of the turbs is 7.7:1
