Whats the Biggest crank arm that will fit in this thing? anyone know? 95mm?

It's cold as hell today (and blowing 40+mph gusts.) IM stayin in the CNC shop. To damn cold to go up to the dynoshop.
So I have my Mic's, calipers and digitizer chillin in front of me.
And a sheet that has the dimentions of several Gt28-30 series cartrige flange, heatshield height and their turbine dia/trim/bladeheight.
I also have the BW apart (you cant believe how fun that is).

I beleive I can machine(and weld a ring to) the Turbine housing from the BW to accept a couple different trim garret GT turbos. possibly even the Gt3071-wg with it's 56mm exducer. The OD of the Compressor housing will also be of concern due to the high & tight mounting position of the factory turbine. Im going to call Brother Pete over at DW diesel and see if perhaps we can get the turbine housings from BW and how much$$. it might be an economical way to get the lower case setup going. 3071R-wg's have a 2.75" inlet availible.
