626 manifold quetsion....yet another thread

If you had read my previous posts you would know I was running a J and S safegaurd. It is a knock detection system that is unmatched. www.jandssafegaurd.com if you have never heard of it. No im not phisically hearing the ping that would be almost imposible at low levels. I have a monitor in the car that tells me when detonation occurs.

And when it does occur it is corrected via the JandS.


haha. My bad. Sounds like you got your system hooked up well. I guess I'll have to check that out - sounds expensive.

I would have thought the factory computer and knock sensor would do the job - are they not sufficient I guess?

is your car on mazda626.net?
if so..i love it
ya, its on there, viper3205 is the name(don't ask me why...) but i've also got a build thread somewhere in the Forced Induction Tech on here.

thanks.
 
yea, i spoke to you in there
i requested some front bumper pics with the intercooler

it looks sick as ****!!!

i want one!
 
I got a lot of work to do still....like get a new tranny, as i busted mine, ands its definately being held together with JB-Weld. ha, but it works. anyway, i really wanna get protephiles turbo manifold, and i really wanna get a GHL downpipe too.....and then comes a new turbo.....gah, it doesn't end! i hope to hell i win the lottery, i'd keep this car and trailer it. full race trim 626, heh.

Well im not going to go into it to much on this thread but if you go to this one http://www.mazdas247.com/forum/showthread.php?t=123643129 , there was a big discussion on why the J and S is better then stock and other knock protection systems. The discussion starts at about post #60 and goes on till the end if the thread.

i thought of the following problems and their solutions:
1)fuel rail, in fact, does not FIT
Solution: USE THE OLD 626'S FUEL RAIL, **** IT.
OK I got this covered now

2)Fuel lines, in fact, DO NOT FIT either
solution: cut 1/2" from the 626 fuel rail, make sure you trim the tip very good...then install stock MSP fuel line...FITS like a GLOVE!
Any pics of where cut was made?
3)MSP Injector size does not fit 626 manifold. and using the 626 injectors is not an option!
Solution: remove the little black spacers and bolt the fuel rial directly wihtout them!!!!
So you removed the fuel injector O rings? I would assume that would leak.
4)EGR Valve has bigger screws than those that came with the original 626, thus, not allowing to fit those screws!
Solution: use the stock 626 EGR holding screws or if at all possible, don't use EGR altogether. Instead, leave EGR plugged in hanging around in the engine bay. As you can see, it wasn't so hard after all!
My EGR seemed fine, but I also had issues mating these up. I may try it without connecting the tube.

I think we were able to use a longer bolt and nut to extend the support bracket and reach one mounting hole on the mani.
 
i ****** up the o-ring on the stock msp fuel line and i said **** it, so i went to autozone and bought fuel lines and made my own fuel line...

the spacers i'm talking about aren't the ones for the injectors...are the one for the fuel rail when it mates to the mani where the bolts go, just remove them and there you go, the injectors will fit
 
we should measure both manifolds since they looked almost identical except for the egr pipe location and fuel rail mounts
 
oh yeah, dude, WTF?

everyone kept saying they were so ******* different, but now...comparing them side by side they both have the smallest part of the manifold at the same size, making it abottle neck...
the 01 looks bigger tho, but if you look closely they are the ******* same!

i imagined this...since maybe mazda had already invested millions on the previous manifold and worked great..so maybe just moving the eGR to another spot and that's it...
just like with the airplane propeller, wright brother got it right the first time, why **** with a perfect design?


maybe i'm just crazy tho...who know
 
Out of curiosity How did u do the injectors. I actually tried this three years when these manifolds first came up and didnt use it because I didnt want to grind the angles wheir the injectors are to sit flush to make sure fuel to air flow wasnt bothered. Otherwise their was a lip by the injectors when our stock injectors were in that didnt sit flush. I was scared some fuel would hit the lip and not distribute well. Only reason why I didnt use the manifold. I did post pics and info like 3 years ago on here somewheir. That is why I didnt use the manifold. Not that everything wouldnt bolt up or made to work. Just that the injectors didnt sit in their the same. Grinding needed to be done to make it sit flush like stock.

Ok im going to post this in this thread because its pretty relevant. I switched to the PG manifold not to long ago and I have a little black thing attached to a brass looking bracket that I just bolted down on top of the manifold. It has some sort of electrical connector(white) going to it and what I assume is a vaccum line coming out of each end. Ill try to get a picture of it soon.

Anybody know what it is? Can I get rid of it? It would really help the area look a little cleaner so if I can get it out of the way that would be excellent.
