Nothing.. but I've slugged a 4088 housing and remachined to the 4094 turbine exducer dimension... I think I do have an odd 4088 that is 1.38 or something.. I'll have to check the shelf tomorrow.
There are places you can send the exhaust housing to be extrude honed to whatever you want it to be. 1.19 is the biggest I could find, so I looked for an alternative a while back.
