Does anyone know the specs for the piston rings for the stock M20B27 pistons?
I'm looking to get gapless top rings for a boosted application on my 325ix from Total Seal but they want the ring landing height, ring landing depth and final bore size.
I have the final bore size from the machine shop but I can't seem to find anything else on the ring specs except the clearances and gap.
Also, for a boosted application will I be ok with the stock gap on the B27 rings or do I need to increase it? I'm looking for about 350awhp so 15-20psi?
Thanks
