I had mine built up by Lee Myles here in the local area... I am pretty hard on it with the FI setup...
I have about $4200 in my build, including an upgraded billet torque converter.
My build included: replacement hardened steel clutches, 5.0 apply lever, 2.0 kevlar band, shift kit, all R&R labor, and replaced all soft metal parts with hardened components.... the only thing I did not do was the all billet shafts, so far little over 10k miles on the tranny with supercharger, and no problems... I change the fluild every 4000 miles and have the bands checked... its only costs me $119 to do that... I call it cheap insurance...
