Compression ratio of an engine (Turbo)
I know that the lower compression ratio you have, the better it is to install a turbocharger... However, what is the problem if my engine has a high compression ratio?
My Evo II engine has a compression ratio of 10.5:1. What is the problem if I add a turbo to my engine? Will it be less reliable?  Thanks in advance for your response... P.S: I know a guy who has installed a Mosselman turbo on a EVOII, so I know it will work, but I am concerned about what problem a high compression ratio engine has when teamed with a turbo...

With high compression, an intercooler is a must And you will be limited to the lower end of the boost scale. You will probably have to stay around 5-7psi.

Thanks Benzmac
 I have one more question: how much power do you think I can get out of my engine assuming I currently have 235hp?

guestimate? with 5-7 psi boost, expect to be around 260-290. imho.
