Thumbs up our first ported oem intake manifold

Well here is a 94-97 intake manifold that was donated by one of the members on here Thanks!

first cut open. The EGR really destroys the inside huh!?



removed the EGR tunnel. It consumed a large amount of volume, removig this helped increase the internal volume size.



This is it before it gets welded. This was without the thermal ceramic coating option.





Overall as you can see the last cylinder on the right is the largest hurdle in this intake manifold design. We plan on giving this to a member who whats to try it out and tell us how much better the car feels and responds. We do tons of port work daily and this one was alot of fun, we know we definitively made improvements to the manifold. with as many different manifolds that we have done we know what works and does not.

Yea that wasn't the best solution on Mazda's part there or more efficient ways to mount the EGR devices.

For the few different styles of OEM manifolds we are willing to port them out. PM us and we will discuss what were looking for. We really only need one of each.

I've got a 99 intake to donate if needed.

Edit: also have a 94-97 as well. Both ready to ship.

I'd like to see what you can do with a '99 intake, lots of unnecessary material in there.

If you DO do a 99-00 intake manifold, I'm curious to see how you deal with the VICS resonance chamber. completely removing it might be a mistake depending on the end goals of the car.

I don't want the VICS chamber removed or butterflies disabled on my 99 manifold. However if someone has another manifold to donate to the cause, and if Brandon wants to port it, I can back to back test various configurations.

I do want the VTCS system removed on the 01 manifold. EGR too, especially if it looks silly like the pictured NA8 manifold.
