Just offhand I think the prices from Majestic were $300 for rebuild, and ~$250-ish for a wheel upgrade/machine housing (per side).
This was sending them flybynite's specs on his upgrade,same wheels etc..

The prices sound good. I would make sure they use a t3 style compressor housing and a adaptor ring for this mod. The tiny t25 housing will not flow the cfm of the larger housing.   :icon_mrgreen:   I used a 3" in and a 2" out on mine..
