Does anyone make a 60cm turbo. It seems for those of us who want modest gains in HP, its either 57 and then goes up to 62. The 57 IE Super B is great for my high altitute but gets a little short over 400hp. I think a 60 would give me growing room if I wanted to get to 450. It seems like this size would sell great.

HX40 = 60mm (some of them)

still doesnt perform as well as the super B 57mm

You can run a super B well past 400 hp. Two of my buddies were pretty comfortably making 450-470 with super b's on 12 valves.

My friend just dynoed his special at 585hp...

Look at the garret turbos you find a nice in the middle set up.

HTT makes a 60mm upgrade wheel for the HX
