What are your experiences with the 160* thermostat. I understand that, obviously, the engine will run cooler but my only concern is how the rings will swell in order to fill the space between the pistons and cylinder walls. I ask because currently with the rear mount, when the engine is cold, theres not a lot of power and I hardly make any boost - I'm assuming because the rings haven't fully heated up so the engine can't quite push enough exhaust gases to really spin up the turbo. I know a ton of people are going to say the problem is the location of the turbo but I'm looking beyond that. It's still a turbo, regarless of where it is mounted. Yes, I am going front mount when I swap engines and the bottom line is this: How good of an idea is it to use a 160* stat on a 6.0L with a front mount T-76?
