the answer is: the most you can
What engine was that? I know the Mazda engines have 14:1 (I think 13.5:1 for the US version) with direct injection and they made it work on 87. Their new HCCI engine I think is like 16:1.

Mazda and Toyota seem like the only ones making reasonable statements nowadays. All GM is doing is caving in and admitting their supposed "sins" of building trucks and SUVs and going on and on about how they are going to be "part of the solution" by banning internal combustion engines and ignoring facts.
