Nice link, I noticed he had another page that talked with a "ported" vics mani. I remember people in the protege world running a "cut" vics mani's on their early 90's protege's. They appeared similar inside and iirc the idea was for top end power or turbo applications.

Yes and No. The bolt pattern is the same for the 94-97 as th 99+, but the problem is the runners are shifted 3/4" higher in the flange for the 99+. So it will slide directly on, but the runners will not meet up.

Now you can modify the flange byt welding on extensions to the flange and drilling new bolt holes. At this point the runners will match up. I am trying to do this as we speak with a 94-97 intake manifold to fit on to a 99-00 head to see if there is are any gains from this simpler maifold.

You rock/thank you.

Its also good that others are doing this testing. If it were me I would probably just risk disaster and JB weld some inserts to the flange. Welding is a good idea.
