the b6t manifold prob wont bolt up because the mx3 motor is just like the 1.6 miata. the bolts line up but i know some of the coolant passages are different. i put a miata manifold on a b6t and had to ad a coolant nipple for the heater core. not sure if it would be worth it i would just use a hammer.. the mx3 one probably flows better..
i just looked again and they did use a hammer. i have a few b6t manifolds if you want to try pm me.
