i have one with a 12a and have one with a 13b, the 13b is NA turbo, hardest part is clearing the turbo to the frame, which still isnt that hard. stand alone is easyer, well for me cuz of what im doing. and rotarys are awsome motors, put some 3mm apex seals in and golden for a long while, i would recomend a fuel cut switch too, to turn your engine off, or when you turn the key off hold the gas pedal to the floor, there have a bad problem with flooding.
