626 manifold quetsion....yet another thread

[shabaka]

Me too!
HOw did u find that out?

some random search on flow rates/swapable parts, for this motor
there is just not alot of info out there for this motor

you 'might' see flowtesting from 'someone' of three different manifolds very soon

sweet
very cool Cap'n, make it hap'n

I also noticed that our sotck injectors do not sit flush in the mani.
They are recessed.
Do u think trying the 626 stock injectors with the stock 626 fuel rail is a good idea? The injectors are not similar in appearance.
I am worried the flow rates might be too different or somesuch and the ECU will freak. Plus the fuel lines dont match up, so I'll have to get creative there...

 

[Alejo_NIN]

the fuel rates and the response are incredibly different, so much, it fuel cuts at high rpms because they just can't keep up

Bump for updates

 

[Alejo_NIN]

as of now, no updates...sorry

i'm a little disappointed on the fitting of the injectors...

 

[TheMAN]

the stock 93-97 626 fuel injectors are rated at 230cc's, which is a lot less than our stock ones

the time and effort you are spending is a waste of time just to save a few bucks... I already said before that the 93-97 manifolds are very different and won't work (without doing all sorts of stupid s***)

so throw this s*** in the dumpster and move on with life

 

[Alejo_NIN]

dude, relax.....i know you are a very knowledgeable person...you are god when it comes to cars....

but please....don't spit on my stuff, ok?
i know something very useful you can do, for me and for many others who are following my project, and it is to stay away.
Your advice is very well appreciated somewhere else.....
the only time i'm wasting is mine, and only mine...not yours..or maybe it is to you by reading this "s***" ...so don't waste your time..please..stay away from this "WASTE OF TIME" and do something better with your life.

and guess what?...you have given me even more reasons as to WHY try and make this work....the CHALLENGE
i know i can just go and buy one...but...where's the fun in that?


thank god not everyone thinks like you....otherwise...there wouldn't be any inventions...since at first...most of them looked like a "WASTE OF TIME"

peace

excuse my english

 

[Alejo_NIN]

by the way, noone ever said i was gonna use the stock 626 injectors....i wonder where you got the idea...

and if i recall...i think it was me the first one to state that the 626 injectors won't work...i already tested them

 

[Alejo_NIN]

ok guys, the ******* time has come!
i'm in the precess of installing my 626 manifold.
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.
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!
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!!!!
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!

now, go and enjoy your beautifully made pre 2001 626 manifold for 80 bucks!!!!

Without the egr valve, you are going to get a mil. Probably will ping too. Keep a good listen under boost.

 

[Alejo_NIN]

update:
EGR valve is installed
only thing is, fuel lines don't work!
they leak, i gotta buy new fuel line hose and install it with clamps.....
manifold is up and torqued down....
all is left to install is the throttle body and i'm home free!
don't wanna install it yet coz then it'll be hard to install fuel lines

My EGR valve has been disconected for almost 8 months now. I have only had some very minor pinging during boost and its only happend like 5 times.


PS. This info is brought to you with confidence by J and S Safegaurd...lol

I HAVE AN ANNOUNCEMENT TO MAKE!!!

AFTER INSTALLING THE 626 MANIFOLD....

DRUM ROLL.....


THE CAR STARTED!!

one thing i notices was that it kinda revs faster
and, on every rev it blows off harder

gotta do a test drive, but the 626 is a GO!!!
it ******* works!!

in your face to all the loosers who said it didn't work!!

 

[Blackrose]

Congrats man nice job.....

took it for a test drive and
WoW!

yes but does it make any extra power? butt dynos are marginally correct at best and revving fast and blowing off harder is subjective. I have noticed things about my 626 manifold but not sure if its the manifolds doing or if it is just an MSP thing. Also to the person who said the lack of an EGR creates pinging where in the rpm range and under what kind of load did this occur?

of course, butt dynos suck

i had never stated any horsepower gains....merly saying that the low end feels better than before

also, if you look at other posts, i had a manifold leak...so by changing the manifold, the leak disappear thus making it feel even faster to me as when it was leaking...

i gotta go to a dyno, actually, i will on april 4th....wish i could've gone wihtout the 626 mani...but well...we'll just compare to another similar set up and draw conclusions..

The EGR is designed to reduce ping. That the point to a Exhaust Gas Recipricator. It takes inert not compustable gas and recycles it into the compustion chamber. This reduces the chance of pinging. This also alows car companys to advance timming in cars to make them more efficient. I think though; in the MSP's case the timming in the car is already very conservative. Thus the msp is less likely to detonate anyway. But in a N/A car with some more aggrestive timming pinging will occur. And some MSP guys have gone as far as to blame the lack of an EGR to there blown motor. I dont see it but there is a minute posibility. Like I said in my case I get no pingin with a lack of working EGR. And i am very modified.

yeah the reason i was asking about rev range and load is because the egr only opens up under low load cruising conditions. I just cant see how the EGR attributes to the pinging people have at WOT high load conditions. I have been running without an EGR ever since Ken did the first group buy on the 626 manifold i was one of the first few in the country to be running the 626 mani and have yet to get any pinging. And Alejo i hear what you are saying the car felt alot stonger in certain ranges i need to sit down and compare my hp/tq curve with my buddies MSP since we just dynoed

 

[Alejo_NIN]

i'm the first one EVER to be running a pre 2001 626 mani! hehehe
