I am putting 96mm KB's into a 2.0 liter motor, stock crank, stock rods, heads will only have slight flycut (just enough to get sealing surfaces back). Cylinders are stock 94's bored out to 96.
What will my compression ratio be? I know this is a combo that many have looked at or built before. Maybe someone knows or has measured. I want to get an idea of where I will be with no additional mods. |

I was not looking for an exact number but wanted to know if someone had measured their CR for a 2056 combo and could give me a general number. I would like to know if I am going to be way off in either direction because of the KBs. From what you are telling me it sounds like anything is possible depending on the heads.
Mark, can I use a buy a head CC kit somewhere? Will a type I kit work or do I have to make my own? Thank you Mike, Jake, and Mark for your responses. If the factory was off by as much as 2 cc then does that mean the CR of stock engines varies wildly? |
