What is this cut out on my exhaust manifold for?
Monday, January 16, 2006 9:42 PM
Ok well i am putting the turbo in this Friday and the turbo manifold i got doesn't have this little notched out piece on the drives side port, but my RK sport header and stock manifold has this?

Is it just for emissions? i am thinking i might just grind it into my turbo manifold just since the car has it for a reason... so i might as well, but i am curious as to what it is?
might be a exhaust temp. thing?

You can see it here in my picture i took when i put the header on... its on the left side...

Thats the EGR passage, you don't need it.

BTW, you're stock gasket will block that off, you don't have an EGR so you don't need to machine it into the other manifold.

Nope, you don't have an egr, so nothing to throw codes.

Just because they didn't change the castings from the 96-98 models, its easier to just put a gasket in there that blocks it off. Aftermarket ones have it to maximize marketability, they know that the only thing needed to use it on a 2k+ is the blocked off gasket.

actually gm did change the casting if you look at your picture above the egr section is blocked off by a small wall


rk has the header setup so that it fits 96-02 , and the 96-98 have egr , its just so they have less parts to stock , and cover a wider range of years


but you dont have to worry about the egr stuff

You want to twin-charge your sunfire but you don't know what the EGR slot is on the exhaust manifold?

Bro I know your dad can do all the calculations but the more questions you ask over time the less confident I am that you'll be able to do this.

I'm not trying to slam you... I'm actually more or less a bit worried you're in over your head. What you want to do is interesting for sure, but I'm wondering if you really have the experience and knowledge to pull it off? It's just such an expensive and involved project to go f*ck up because you were overconfident in your abilities and resources.

I'd like to see you succeed, which is why I'm questioning you... these forums are about support so what I'm saying is I support your project BUT I feel the need to question you and hopefully make you question yourself a little bit... just to be sure you haven't bit off something you can't chew.

Either way, good luck Josh.

i just wasnt 100% sure.. its not like im asking "which side does the turbo go?" or "do you think i need an intercooler"

I know your not like the rest who just want to see this fail... but it was just a small question as to if it would effect me or not... as i couldnt remember if there was any thing behind that when i swaped out the manifold for the new header...

ahah go back and look at one of my older posts about this... there is a list you could probably make... every one says it wont work but not one person who said it wouldnt work could give me a reason as to why they think it wont.. except the normal "the supercharger is to small" which shows right there that they no nothing about it
i know SunfighterGT isnt one of them as he hasnt said any thing about it so i wasnt getting mad at him saying he was... and with him being turboed as well im sure he knows a thing or two that i dont know... like the little things you cant plan for or know that will happen...

well i dont want to get into that arguement again though... car goes under the knife on friday and i guess we will see what the out come is in a few days after that....

I've read those posts before, i don't recall anyone saying it won't work. I just remember a lot of people telling you that a proper turbo set up would be more effective / efficient than using both together. Yet you keep claiming that everyone is againts you, you just don't get it.

EVEN IF no one is against you ......... I think people were just trying to say your wasting your money for not really ANY more power then you'd see from a good designed turbo kit. that being said.

YOUR DIFFERENT...... when you show up somewhere and people are like WHOA that thing is quick...... you can say yup "Dual charged"....

No one here can say that ... YET............ so even though the power up won't be extreme....... you'll still have that different really cool sunfire that is dual charged.......







so forget about the people that are questioning WHY you doing it vs. just getting a good turbo set up....

and focus on THE FACT that your different!!!

and that you have BOTH !!!!!!

Good luck Josh..... KEEP US POSTED......... I want to see at LEAST 100 pictures of the install................lots of pizza boxes..... and a DUAL CHARGED SUNFIRE !!!!!!!! WOOT !!!!!

no problem... and people seem to think im getting mad about this stuff but im not... its just i get no support from the Jbody crew and HUGE! suport from the muscle car and import car crew.. oh well i guess

Lee - ahah yea ill try for the pictures.... it might take a while for install between my 60hr weeks at work and then 3-4days a week hockey as well...

kind of off topic but the pipes on that header are paired up wrong thats kind of a really big mistake on the manufactures part specially it being a tri-y header there would be next to no gain or nothing at all running that over the stock manifold which is a tri-y the two outside pipes should be paired together and the two inside ones should be paired just thought i would point that out u can tell the manufacture never went near a dyno with it just got it to fit in the car and called it good.

well when i put it on i felt nice gains up top... and the stock one is soooo restrictice... if you go on my cardomain page you can see all the photos and see what i mean.. but oh well its not on the car now..

Twincharging sounds like such an awesome setup. It sounds like something only real racers use and something to envy. But in all honesty anyone who really does know what they are talking about, knows that it's inefficient and pointless. Completely not cost-effective. I'm not slamming you, I just think you need to realize that there are better ways to spend your money.

Yea i know your not trying to slam me... and i do know what your saying... i know i could built a strictly turbo set up to do the same thing.. its just the original factor that i like about it.. and i have the supercharger on it already and dont really want to sell it so i thought i might as well use it since it works...
That and money isnt a big thing right now for me... no bills or any thing.. Just insurance and gas... and a "car" loan i took out to get credit for later on when buying a house, but really its just to finish buying things for my car

Thanks man... ahah tuning may suck i am ready for that.. but if you think about it, it will be no different then turbo guys tuning... boost is boost... the engine doesnt differenciate the two.. .its all the same going into the engine... and the waste gate is going to be seeing whats going into the engine so that it will always be 10psi and the turbo will adjust to it... And my GReddy eManage has already been tuned on a 2.4L turbo engine to 10psi with the hole wide band O2 and every thing... so i may need to do some adjustments, but that will be done on a dyno just to make sure...
