Does anyone have a list of the holset turbine housings in cm converted to a/r? or is there a formula of some sort? May be going a different route now and I am looking for a twin scroll T3 Holset turbine housing that is about .82 a/r. Also does anyone know if there are any somewhat small T4 holset housings?
The smallest divided T4 housing that I know of 16cm which is pretty close to 0.83 A/R which I had a lot of trouble fitting it on a bottom mount manifold. So be pretty happy you found an .82 A/R divided T3 cause that's probably the smallest you'll find.
Holset doesn't make small housing. They are for diesel trucks and semis. But if you're wanting to find smaller divided housing and need to know the cm to a/r equivalences it did mention them in past Holset threads.
