I just bought an BD super b turbo, and in the instructions if says you may have to modify the engine mount a little for clearance, 1/4 in or so. well when i went to install it i noticed that i would have to make clearance for atleast an inch, and decided that was way to much and installed the factory turbo for the time being. what im wondering is if there is some way i can make that turbo work, or if i should trade it back in for a different turbo?
