    Couplers???

    Does anyone know if the stock coupler between the 78mm MAF and the 78mm TB will connect to a 90mm TB? If not does anyone know where I can get one that will connect to a 78mm MAF and a 90mm TB?

    if not, i would suggest going to Home Depo or some hardware store and picking up a Fernco Coupler... most use these anyways instead of the SLp smoooth bellows, and they fit a little big over the TB untill you suck them down with clamps

    Fernco, but to stock sized MAF and TB... they would easily fit something larger....

    Fernco's (proper name no hub band) come in many sizes and shapes.
