January 31, 200917 yr #1 Jus wondering if someone can tell me the compression ratio of our 4.0lt turbo engines? And what makes different to a N/A 4.0lt?
January 31, 200917 yr #2 Don't know about the previous models, but the FG turbo is 8.8:1 and the non turbo is 10.3:1.This information is available on the Ford website.
January 31, 200917 yr #4 Apologies: 8.7:1 for Barra 240TAs for differences, have a read through the dozens of other similar questions posted since their release, there's a few out there! Edited January 31, 200917 yr by Superdan
