626 manifold

what if you block egr line both from exhaust mani and intake mani? ive been wondering what does that do?

and thats a much debated topic...

 

[neox.286]

yea a lot of people will say that it can aid in predetonation by leaning the mixture out, and a lot of people say thats b.s. and that its not a bad idea to do since the egr causes a lot of problems with our idle usually

*shrugs*
I just left it on cause I didn't see the point in blocking it off

 

[23dude]

sooooo i wont be blocking egr lol, has anyone had any problems with the intake swap at all? because im gunna have to visit junkyard lol

 

[808MP5]

i would say the only problem that ppl mentioned was that the brackets underneath don't line up anymore... i have yet to fix this on mine but too lazy to get up under the car... besides it's holding up pretty good... it would take an extreme hit to crack the IM i would guess

 

[23dude]

yeah i think it be extremely hard to crack the intake mani

 

[neox.286]

they do not line up right away, but the brace is adjustable...its got 2 bolts on the manifold and 2 bolts on the block....loosen up the two on the block and you will be able to adjust it up and down and you should be able to get it lined up then

I ran into the same issue, but I just removed the brace because it really wasn't necessary considering how light the 626 is in comparison to the bulky as hell stock manifold, but let me know if the brace lines up after adjusting it

people say that the 626 mani has some pritty good gains. is 20-25 whp accurate?

bwt neox i friggen love your sig.

 

[neox.286]

hahaha, thanks

yea, some gains have shown that high of numbers (protege garage has dyno charts of the gains)....youll loose some low end but gain high end if I recall correctly

I just used a carbide and made the holes larger to get the bolts in.

hey, i got somebody to put my 626mani in my msp and he SCREWED UP the vacuum lines. i have no idea what goes where. for example, is it correct to loop the two vacuum lines together down on the runner? (if looking at intake installed, the bottom two ports/nipples right next to each other on the lower left side of the intake) i need help. i'll call somebody if you want to walk me through over the phone. thanks

that blows dude!! good luck i wish i could help.

 

[wickedjra]

blows big. i just went and made it so everything that looks like it needs a vacuum connection, got one. now i get my boost, but my wideband gauge is showing a big fat "10" as soon as i get positive PSI. what now?????

hey will a 99 intake mani fit on our msps?

the 2000 to 2002 is generally seen as one that fits the best and is setup to supply the best gains. the ports might be smaller/different on the older manifolds.

i read another forum and the dude was saying that the gains are the same, but its not a bolt on. you might need to drill and s***.

 

[spoolin_05]

yah after researching a lil more the older 626 manifolds would suck to try and fit on there im just gonna keep searching for a newer year.

make sure to get it federal emissions without VTCS/VICS flaps. junkyards normally won't or don't discern between the two.

how would someone like me tell?

 

[neox.286]

itll have stuff attached to it on the passenger side with vacuum lines going to it...it'll be easily identified as a vacuum-controlled actuator for two different sets of butterfly valves
