626 Intake Manifold N/A Simplified

[norwood1026]

Sorry norwood1026 just people have posted here saying it does work. Its one of the easiest mods to do.

Nothing N/A is going to give you massive gains from anyone MOD. Cept a retune perhaps.

No worries the only reason I asked that is because some had said that using thier butt dyno they were able to feel something. But they haven't really put it on a dyno yet to be sure. I'm going to put one on mine but then I'm going to get it put on a dyno to see what results will be. Be intresting to see.

jeez, you guys, do WANT me to do a dyno??? lol

if i have time this weekend, i'll see what i can do...

NICE... you'll be way high in my book if you do.(2thumbs)

i have a pre 2000 manifold im planning on putting on. also been lookin for places to dyno if i do just so i can see where im at. so if i do before anyone else ill post it up

i think with the pre2000 the fuel rail wont line up and you'll need to modify it

send it to me and i'll clean it up, powdercoat it whatever color you want

 

[probin94]

haha....how much. i got a buddy where i can take it to sandblast it(the outside). i was planning on painting it myself. i already cleaned out the inside pretty good with easy off and took of all the other pieces off for the cleaning of the outside. so depending on how much its a possibility because i got this real cheap.

 

[zoompastu]

mine is a pre-2000 also. there is a way to modify the stock fuel lines to accept the old style fuel rail. I'm curently running injectors from a MX-6 with bosch jetronic tips on my stock manifold and fuel rail. yes I know that the old style injectors flow a little less than the newer fs-de injectors but on a 1.8L it is an upgrade. the injector solinoids are bigger too. same injectors in the picture

I still have a haaard time telling the difference, between the 626 manifold and the stock 323...

Does anyone have something like a picture or the likes to compare the two...?

Its hard to see anything on my picture with all the wires and crap, but you get the idea of its shape/size.

 

[zoompastu]

like a lot of things its whats on the inside that counts. the 626 manifold is a one piece straight through manifold. the Protege (323 in your case) is a two piece manifold with buterfly valves (for VTCS and VICS). How many performance based cars have a system to cause Turbulance (resistance) in the intake to heat up the motor faster with Two ####ing cats pluging up the exaust. Zero. These FS motors are SULEV (super ultra low emissions vehical) compliant and these are cheap grocery getters. now they can be modified to be hardcore performance monsters but they NEED to be modified. stock manifold is crap. the 626 manifold is better. but a Properly flowing manifold with a large plenum and high velocity runners is best. or a good set of I.T.Bs with an airbox like bmw uses on all of there M cars. (american S50 and S52 E36 M3 motors not included)

^^^^^
Soooo...do you take out the VICS as well.... for the stock intake manifold? It seems tho that the vics ports...the air lead to nowhere... whats the deal

no you wanna leave the vics ones....at higher rpms they engage and give ya more air

Oh, that picture is spot on. Thanks.
Regarding the VICS, I seem to remember it being used more in the US, than in europe, but I may be wrong. Other than that, my FP-DE doesn't have it...
As far as I know, its only the 2.0 FS that has it, so I should be going after a 1.8 626... right?

I.T.Bs are as good as illigal to mount here, if you don't spend big $$$ on getting your car legalized.

 

[TWISFM]

So for the pre-2000 models on the 626 manifolds....the egr doesnt line up.. which none do..what exactly do you have to do to make the fuel rail fit for the protege 2.0l

 

[zoompastu]

you have to get different fittings that click into the stock fuel lines and then run fuel hose from those fittings to the old style fuel rail.

 

[The ManLaw]

soo... i think someone should do a write up of the process or atleast a list of everything needed for a mani swap to a 2.0l protege engine and i'll do a write up if i can aquire everything needed

there is no need to do this if people buy the right manifold, no offense. 2000 to 2002 federal emissions mazda 626. rail bolts right on, manifold bolts right to head, throttle body bolts to manifold. it goes right on, the only trick if any is getting the vacuum lines right.

 

[The ManLaw]

ah yeah thats why i mentioned a write up, i didnt know if there was any special tricks that need to be done with the vacuum lines or not. i saw something that they need to be set up with T fitments
