D16A6 needs a kick in the ass!

[Kaan]

under the rules the ZC pistons are legal and generate the most compression... yes compression = power.... but the best build seems to be with the A6 top and bottom... it seems to produce the best overall results even though it doesnt produce the highest compression. though you can within the rules produce TONS of compression with the motor non the less... decking and head gaskets that is.
