A few years back, a friend of mine made the infamous 2.7L DSM engine and ran it around with a 14b. He said it had no issues and went like a bat out of hell. I didn't see it personally, so it might or might have not been true.

Yeah it will just bleed off the extra boost, but remember this is a stock car. Honestly, I've never tested a oem car with a 4g64 shortblock on it. I would imagine the factory system might not keep up with the boost control.
I know alot of the smaller MHI turbo's seem to spin apart when you start upgrading flow. A few members on here have lost a variety of turbo's after switching motors, heads, cams, etc.
