Anyone know if a GM3 cold side housing and impellar will fit on a GM4? I'm trying to make one good turbo out of two.

Should fit fine.

The Hot side impeller and shaft are ballanced independently from the compressor wheel.

The basic differences are the brackets and how some of the stuff connects.

Give it a go, if it fits and all seems well it should be fine.

Apparently it does fit. I did the swap and slapped it on the truck. Seems to have cured the oiling problem. Thanks.
