I will be starting a tear down on an 07 M8 this next week. It was an insurance total that me and a friend will be rebuilding. We want to order a turbo for it but want to get some honest opinions on which one (pro's and con's). The sled is stock and only has a 141" track. We ride lower alt. here in Alaska 3-6 feet. We don't want a Avy shoot climber, just a fun boondocking, hill climbing pump gas sled. Thanks for any info.
