compression ratio stock?

[sonicboomer03]

Ive searched the forums here, and couldnt find anything for my specific setup. I have a 99 Z24 (2.4LDOHC) Does anybody know the stock compression ratio. Im guessing around 9.4:1-9.5:1 but I need to know exact. Thanks

Ive got a custom turbo project coming up, and Im getting the stock specs together for the math!

i know the chiltons manual says 9.5:1 for 96-98(thats as new as the book goes) i would think the 99 would be the same as 98 2.4

thanks, Ive found some other online sources that say the same thing: stock 2.4L twin cam is 9.5:1

Apreciate the help!!
