626 Intake manifold

[.mazda.speed.]

I am doing it right now, and I am just noticing the two manifolds are alot different. I can not see where some things mount up, and the break booster line is not there on the 626 IM?

Any help from someone that had done it before is greatly appreciated!

I cut the stock brake booster line and used a couple 90* angle adapters to make it work. Stuck one elbow off the largest vacuum nipple on the 626 IM, then used the part of the stock brake booster line that has the check valve in it, then another 90 elbow into the brake booster unit.

If you try using the stock booster line it will kink and your brake will be so stiff that it'll prove to be 100% useless.

You'll need to redo a lot of the other vacuum lines as well, cuz the 626 has the nipples in different places and it also has one less overall. So grab some vacuum lines and t's and get to work :)
