Does anyone know what the compression ratio of a d16y7 dx engine from a 97 civic and what the compression ratio is for a d16y8 ex engine?
and would anyone know the compression ratio on a Mini me between the 2 engines, i have a hybrid(d16y7 block d16y8 head&intake manifold)

im turbo charging my engine and i need to find this info out, and anyway i can lower the compression if its too high?
