Turbos are Dumb

Yup, dumb. They don't know if you are running a gas engine or a diesel and they don't care. All they know is the volume of exhaust driving them and the volume of air they are compressing.

So, since a 700 cu. in 4-stroke diesel at 2100 rpm uses the same amount of air as a 350 cu. in. gas engine at 4200 rpm, the turbo won't know the difference.

However, big diesel turbos are built for long service life which means heavy parts and slow spool up, so you may want to look into what size diesel turbo really converts to your gas engines needs.

By the way, all those GMC "Roots type" blowers were originally developed for diesels. (I know, I know, it's not a turbo. But it's a blower none-the-less and it certainly found its way onto gas engines.)
