Mazda 626 Manifold Swap question (2003 Protege/MP3)

[Marz_130]

Hello everyone, i have a 2003 mazda protege with mp3 powertrain, harness, and computer. i know the 626 manifold is a common swap and i found a 94 manifold for cheap but i wanted to know if I should wait til a good 1999 626 manifold pops up or is it all the same?

I have a 626 valve cover to go with all that......maybe the coils too............

Skip the 626 manifold. You'll lose some high end flow, and you'll lose the VICS chamber. Keep the Protege manifold, and remove the VTCS butterflies at the head ports. The MP3 manifold kept the VICS, but deleted the VTCS. By running an MP3 ECU, you want to keep the VICS.
