I've been running a MP 60mm TB on my '95 and when I move it over to my '99, I want to make the transition smoother between the TB and manifold and eliminate the step. I'm a bit hesitant to open up the stock intake manifold to accept the TB due to the small neck, so I was thinking of purchasing a TB spacer and opening it up to 60mm and having it taper. I would feel safer having a taper that started from the spacer and possible continued into the manifold. Would that work, or would it be ineffective?
