isn't the opening on the intake manifold only 78mm or something like that?

so the 85mm TB would be pretty useless.

save your money, get a stock TB ported

i suppose you could argue that an 85mm TB with the 78mm intake opening as the restriction is better than a 75mm TB being the restriction.

but still...port your own...save the money
