diesels dont use gas!!! 93TSi next time, type fuel mileage.....lol!!

Your dumb. diesel trucks get better gas mileage than alot of cars.. like my dads ram gets like 23 or 24mpg

t88 I think

what kind of turbo any one know for sure?

Hah, if that thing boosted any higher, the bottom end would fall out of the motor and the block would crack. But I wouldn't blame it, after all, it I S a gm!

Lol, more import bashing...yeah, congratiulations on the monumental achieve ment of getting 1000hp out of a 6-liter engine...how impressive...The only thing that's keeping that chevy from falling apart is pure luck, just lik e most gm products
