"Big"? LOL a Garrett GT60 is big. My Holset HX82's would eat that little thing. HeHe. If you look at my avitar that 2-Holset H5C's feeding a Holset HX82.
Ok all kidding aside. This is a great turbo for Diesel truck upgrades or as the top turbo in a compond set-up feeding a stock turbo. Would think it might be hard to spool on a 4cyl depends on exhaust housing though. Price is very nice for a solid performing turbo and if you really want to step it up. Several companeys build Billit wheels for them.
