no im not trying to dote on my job or extracrricular activities
My boss has several Holset turbo's for sale. These were built for a diesel but were going to be used on his CNG car. They have a 5.5" exhaust outlet and a 4.8" inlet. Looks to be standard exhaust squared inlet, I have the engineered plans from Holset and can get you any dimension you need. It sayst that the compressor housing can be rotated independently through 360*.
I will get pics as soon as possible.
here is some info.
