I'm also thinking of doing a vnt. Not the egr 60 series ones though.

The 75 seems to be a good turbo for the Detroit. Not sure why you were having heat issues unless your gearing is wrong and your lugging it. Your referring to the 75/96 Borg with 1.32? I don't do a lot with Detroits but they seem to preform the same as the other smaller motors with that charger like the C12. I've just noticed some guys like to drive their 750hp+ trucks like a 450 and keep RPM low for fuel mileage. Then they wonder why they don't survive.
