do you get better gas mileage when u bump up the compression? i know u get more power, but i was curious the different ways to increase your compression, thinking about doing that to a diesel motor (probably a 6.5 turbo diesel) when i drop one in my suburban. (dont tell me the 6.5 is slow and weak, gets better gas mileage than any of the others, minus the 6.2, and gets quite a bit more power/torque with a turbo and a computer upgrade, just looking to get around 600 lb/ft of torque, nothing more)
That may be true, but they are prone to cracking the heads where the Injectors poke through.
