Just curious if anyone has used this turbo on a Buick. I was visiting the Supra boards and saw that these guys are making 1031whp with this turbo @ 6800rpm and 35ps on a stock unported head and intake (3.0L motor). Claims are they make more snort then the GT4276R turbos throughout the entire powerband. Low 900whp is what the norm is for a GT42 series turbo with all the goodies including ported heads, cams, intake etc. Any thoughts?
