numbers on the 2ZZGE

ok, not really the numbers most thought, but i was wondering if anyone could help on the Compression Ratio for me.

ok CR is figured by the cylinder swept volume + the deck height volume + the head volume / deck height volume + the head volume

i figured the swept volume to be 448.8875cc, im guessing on the other to but deck volume is roughly 2.75cc and the head is 40cc

could someone, anyone confirm this? thanks

the compression ratio would be the total volume of the cylinder at it's furthest point down divided by the volume of the cylinder at top dead center.

so with the numbers you have, it would put you around a 10.5:1 compression ratio.

2ZZ-FE (GTS) is 11.5 to 1
1ZZ-FE (GT) is 10.0 to 1

Its caclulated by taking the displacement of the motor divided by the volume of the head.
