this may be a little difficult, but here goes...
i have a schwitzer S2B... it has a 62mm, compressor wheel, and appears to be the same exact thing as an s300, as far as center section and exhaust housing bolt patterns, and turbine wheel size, just has a bigger compressor... however it is non wastegated and makes way to much boost,

i was wondering if anyone has the turbine wheel measurements off of an s300 like PDR, or BD sells with either a 12 or 14cm wastegated housing (HX40 style). im hopeing i could just bolt one of thoes on.

thanks for the help
