I'm thinking about the boost logic kit for my 93 sc300 5-speed. I was told it did not come with a flange that will work with a ls400 AFM. Where can I get one to hook it up to the intake piping? (its square on one end like the sc300 afm)

Give them a call and see if they have what you need.

 

best bet would probably be to have a machine or exhaust shop make one. Shouldnt cost much at all to make a pattern, cut it out and weld a short length of pipe to. You could then use a regular coupler to mate it up to the BL kit filter. Just bring the AFM by itself in and ask them to make a flange.
