Hey michael,
No.when your talking displacment,your refering to cylinder size.
Altering your compression ratio is a cheats way of making "FREE" horsepower like;less compression=more boost you can run.
You can do this by either installing a low comp dish top piston,or a thicker head gasket.
VL Turbo standard compression ratio is 7.8:1,i would'nt recommend going anything lower than that cos you lose your driveability,if anything id increase the compression to anywhere between 8.0:1 to 8.5:1.more compression has better driveability so either way your choice.injector sizing's somthing you should change too,hope this helps
