I believe the a6 is around 7.2cc,

anyone know if the d157 bottom will fit the 16y7 head? using the 9.5/6 to 1 hf pistons w/ a set of 90 mm rods from a b7 or a6?
Or the formula to process valve to piston clearance on this set up?


running a pr3 w/ an L3 trannie maybe my zc??

can you run an si dizzy (evan an hf) on a y7 vtec head? or is y7 dizzy obd1

I thought it was posible to run a pr3 on a sohc non obd0 a6/b7?

Can anyone spare some thought?
