Well since the other thread was deemed doomed...I am making this thread to collect and post as much info as we can possibly come up with in regards to using this intake on the 2.0L FS-DE Protege and mainly the MSP.

The other thread was closed due to Cullen from SU interfering with us trying to get info on this mani. Lets not have the same thing happen again.I am going to go through the other thread and I would like any mods helping in piecing together the good info from the thread including all pics and anything else we need to include in this thread.
Who can I get to help with this?

All of the info here is based upon the 2000 Mazda 626 Intake manifold for the 2.0L FS motor with STD. Emissions.

Currently Azian6er and tekkie are the only two that we know of running this mani.Tekkie has posted pics of it on his car and comparisons of the stocker to the 626 mani.We are currently waiting of pics on Azian6er's car and for his time to make it to the dyno to test it out in the real world.

The original Thread is here...Read up...It has a lot of info and questions between all of the BS posting.
http://www.msprotege.com/forum/showthread.php?t=123290

I ask all who post here to please be contributive and not let the previous threads comments carry over into this one.

I didnt start this battle but I am here to help it come to a realization.

hmm check this out, here is the placement of the EGR pipe on the stock 626 header, it looks to be in the same place as ours so I am thinking the 626 EGR pipe will fit perfectly :) I will be finding out this week :D

This info is from Tekkie as well

For comparisons sake here is the stock vs 626 manifold, as you can see the EGR placement is not very different, the stock pipe may even work. The egr pipe in these pics are fro the protege manifold.

here you dont believe the 626 manifold will fit, its on my car and if fits no problem, once I get the egr pipe on then I will hook all the s*** up and dyno the b****

but like I said earlier I figured the EGR pipe would be close, but it was not close enough it needs another good 1 1/2 - 2 " so instead of customizing this one I am going to just buy the 626 egr pipe

any gains on this mod for a N/A application?
We are unsure of any info for sure ,but as far as all of the initial talk ,it will lose power on the N/A apps because of the single runner design.Until a N/A car steps up to the plate and tests and dyno's this...It is not for sure.
 
ForceFed-- Do you know what tekkie did to make the erg pipe work? Is he using the 626 erg pipe and did he have to modify it. If he did what modifications need to be done to make it work.
Also what year 626 manifold is that?
 
Unless you're tuned for it I doubt this'll do anything big for N/A. Maybe you'll get better power down low, but I think it'll hurt your top end.

Actuallly,as far as I know the EGR situation of being different has not been resolved. We know that the Stock MSP EGR pipe is not long enough to connect at both of the spots on the 626 mani. Tekkie has said that he is going to order the 626 EGR pipe and see if that works. We will know when he tries that. After that if it doesnt work,it looks like a custom pipe will be needed to keep the EGR function.

I beleive it is the other way around...I beleive you will lose power low and gain up top...Some one with good info on this chime in here.
 
Thanks guys I though that other thread was never going to end. This is very nice of you guys to go thru the trouble of wasting time and money for everyone's benefit thanks again.

I remember someone saying that the longer runners are better for lower end because the incoming air has more momentum, at least for NA cars. I think NA this set up would lose efficiency at the top... not sure if I've got it right... bueller?
 
thanks for starting this thread ForceFed :)

I finished the install last night, but I have a small vacumn line isssue, I think when I clamped down my brake booster I did it to hard and crushed it :(

but regardless of that I got the car all fired up and its running, not running good though because the emanage does not see the vacumn

but I will be fixing that tonight and posting up the completed project :)

obviously with the vacumn line problem I could not drive it but that should be a quick fix

And for the EGR I came up with a different plan if it works which I think it will its a cheap fix, its a stainless steel gas line for a dryer, fireplace etc. I dont know how well this will hold up against the heat but I think it should do the job, and its nice and flexible so installing it is way easier than the EGR pipe.

this is a pic as an example, the one I have was just a couple inches longer than the egr pipe so it fit pretty well
