MP3 intake manifold #

[twizyours]

I was at my dealer today and I tried to find out how much the or half of the intake manifold would cost. Due to their lack of knowledge of our cars they could not help me find the part of the MP3. They said I needed a VIN and they could find it or if I could find the part #. If anyone with a MP3 knows the part # or could go to their dealer and find out the part# it would be appreciated. The reason I am looking for the MP3 manifold is because I am looking at getting rid of the VTCS. I only would need half the Manifold.

Thanks

If you are going to replace part of the manifold why not get the full FS-ZE manifold and at least help the breathing out...The FS-ZE manifold does not have VTCS, and it makes a little more torque.

I first want to see which one is cheaper, and to get rid of the VTCS I dont need the whole manifold. Second I dont believe anyone has taken measurments and copared the MP3 and FSZE manifold, and if it is going to cost a extra 200 for the fsze I dont think it is worth it if I dont have to $450 is kind of expensive for not that much a difference. That is why I am looking too. I want to see what the cost would be for half a MP3 manifold.

The only real difference between the standard Protege manifold and the MP3 one is the lack of VTCS. The FS-ZE manifold has a resonator box which helps make more mid-range torque...

Edwin has it on his car and said it made a nice improvement, particularly with the cams.

Thats what I want to do.

Yes but he was going from a VTCS to a non VTCS not from a Mp3 manifold. Also I dont think he payed $400 dollars for that manifold. I dont think $400 is worth it for that little especcially if possibly I dont have to pay that. Hence if I could find out how much half the Mp3 Manifold would cost. I would only need the top half that goes to the head since that is wheir the VTCS butterflys are.

i believe the mp3 has the vtcs.

 

[twizyours]

No it only has the vics

I cant remember. Whats VTCS and VICS again, and whats the difference. the mp3 manifold looks like the picture of the FS-ZE manifold corksport sells.

Why do you need to buy the lower intake? Just take the VTCS blades and shaft out of your stocker and then thread and plug the control solenoid end. There is a factory plug on the other end. If you are going boosted, then take the factory plug out and tap and plug it also. That's what I'm going to be doing to mine within the next month. Hey, I'm into cheap gains with the stock stuff. Flying Miata tested the stock ECU and MP3 ECU back to back on a Protege 5 and they only got an extra 3.5 HP so the rest of the HP must be in the intake! Especially seeing as how those 2 things are the only differences between the two motors.

That is what I was thinking as well.

I have a manifold complete in the basement if anyone wants it...let me know...

P5 manifold

I have a manifold complete in the basement if anyone wants it...let me know...

I'd like to have one to port and remove the VTCS from before I tear the stocker off. What do you want for the manifold?

Remember 2 things: (1) the MP3 had a different ECU, intake AND exhaust and (2) gross vs. wheel hp. The MP3's 10hp advantage is a gross hp figure and probably equates to roughly 7 wheel hp. Flying Miata's tests were on a dyno which measured whp so the 3.5 hp increase from ECU probably equates to about 5 gross hp, or half of the total 10 gross hp difference. This is almost all from the ECU's advanced ignition timing, which requires premium (91+) fuel.

I would guess that the MP3 intake (by itself) adds maybe 3 gross hp (2 whp) and the MP3 axle-back exhaust maybe 2 gross hp (1.5 whp). If you go one better and get the Racing Beat exhaust (a full cat back with larger diameter pipes) they got 4.5 whp. Still not a huge improvement, which shows that the stock exhaust is pretty efficient.

It's also possible that the MP3 is actually more (or less?) than 10hp more than the P5 and all these calculations are meaningless. Has anyone compared MP3 to P5 stock hp on a dyno?

I have the mp3 ecu its not really that big of a difference just smoother. You do feel a difference between gas though. Also I have a second manifold that will be changed at some point well see then. Everyone that has ported out their manifold has said it was well worth it. you wont notice that big of a difference in a exhaust when you got a tree on your manifold.
