Same rear (housing and wheel) as normal -5's, 2530's, 2540's, GT RS's and -10's.
The comp housing has a 3 inch inlet instead of a 2 inch and a 'revised' front wheel.
It's such a shame they are not direct bolt on.
I wonder where the 'limit' of these little housings are?!?!
Imagine it with another 7 PSI!
