I'm not sure, but think the japs may already have this on the street... But why, call Ned at IA and tell him you want the stage III mods with the porsche 930 turbo (he drives this on a 5ktq), and you got your 400+ hp. The problem or lack of same comes on like a train at 4krpm, a little high for me, thank you. Scott PDQSHIP@AOL.COM
