Okay, so all I need is just the TB itself from a 2008 2.4? Correct?

huckernage

if this TB is 6 pin go for it

xxxxsh4d0wxxxx

iTrader: (1)

Yeah, but I don't know which year 2.4's have which pin!

I'd assume since my 2008 has a 6 pin that I want a 2008 2.4 TB?

huckernage

you can try to find the diagram of rewire from 8 to 6 pin. it here somewhere

what year 2.4 tb would i use for my 09?

xxxxsh4d0wxxxx

iTrader: (1)

There is a way to do it without rewiring.. Isn't there..?

huckernage

there is the way to rewiring from 8 to 6 maybe that can help you

xxxxsh4d0wxxxx

iTrader: (1)

Yeah, see, the thing is, I know there is a way to do it without rewiring.. IE, buy the correct TB from the corresponding year 2.4

I am just unaware which year is as such.. I believe, though, that it is 2008.

huckernage

go in section 2.4 and ask there

Buy a 2.4tb from the same year or it wont plug in.

Alright, that's the answer I wanted, thank you.

Now I just need to find a soul, with a 2.4, willing to sell their TB..

ok, so back to exhaust/ headers
ill come right out and say it, i was wrong

talked with dan this weekend and he supports your side of it. the tri y (4-2-1) header is GREAT from idle till 5500rpm...after that it falls on its face! thats why im looking to change now

my misunderstanding was in the long/ midlength tubes which are GOOD for power, if sized right they can help scavenging and are better up high (someone correct me if im wrong).

he has my car for some R&D work right now that he needed to get done, but when that is overwith we will see what i can convince the gf to let me spend to change things up a bit

xxxxsh4d0wxxxx

iTrader: (1)

Yeah, apparently he told me that a properly designed 4-1 will not even have much difference in bottom/mid, but you WILL notice the difference up high.

Maven, though, told me 4-2-1 was better, and that a small displacement motor is best served by a multi-merge header.

I'm sure it's all preference.

NWAE Cobalt

iTrader: (1)

true, although this explains why my dyno falls on its face after 6000rpmish range...

xxxxsh4d0wxxxx

iTrader: (1)

Who goes above 6,000 RPM daily, though?

huckernage

everyday not everytime, even 7500 on stg2 cam.

xxxxsh4d0wxxxx

iTrader: (1)

All I'm trying to say is the 4-2-1 might be the better choice.

All I know, is I would ask Clear Image, as they're the ones who make the parts, and they would know best.

A properly designed 4-1 can outperform a 4-2-1 in all aspects, even down low, and vise versa!

I believe Dan told me that their 4-1 did outperform their 4-2-1, and that the 4-1 was the better choice.

huckernage

dont forget it is a cam stg 3 thread. you will amputate your low end to get high peak with Cams

i did talk to dan
he is the one that told me that.


if you are looking to buy a 4-2-1 setup...PM me...I can probly help ya out

exactly

xxxxsh4d0wxxxx

iTrader: (1)

Well if you went with a 4-2-1, and stage 3 cams, wouldn't you be getting the best of both worlds?.. My car will probably never see cams as I don't feel like replacing the valve springs and retainers.. If anything it would only be stage 2.

You're selling yours? ^Like I said above.. I want to find out which is best for my application as I'll more than likely never see cams, but who knows.

Does the 4-2-1 pull good down low and in mid range?.. And what R&D work are we talking about?

I don't understand what you mean.

NWAE Cobalt

iTrader: (1)

the setup im selling is GREAT for low to midrange, it makes AWESOME power till 5500-6000rpm....and i need to be able to BUILD to 7.5k rpm....

i just posted a for sale thread about it, but pm me what your looking to spend and we can talk
https://www.cobaltss.net/forums/parts-66/clear-image-4-2-1-header-catless-dp-204597/
and btw...this is PERFECT for you if you are looking to stay n/a without cams

and i cant talk about the r&d work right now....i will when i can

btw, the reason it is not great for a bigger cam, is because the cam doesnt start building till 3500-4000rpm and the header starts dropping power at 5500-6000rpm...so you dont really have much of a power band. having an exhaust setup that works till 7500+rpm lets you build power further and keep in your powerband throughout a race

So with no cams you'd say 4-2-1..

Cams.. 4-1?

I'd consider buying that from you.. If it was catted.

Also, didn't they change how they made their 4-2-1?.. They used to have cylinders paired by firing order didn't they?.. It's different now, though.

NWAE Cobalt

iTrader: (1)

correct on the pairing, it is the original.
its not catted now, but it would be an easy swap for a shop.
and ya, no cams i would say 4-2-1, with cams, 4-1

xxxxsh4d0wxxxx

iTrader: (1)

Any idea on why they changed it up?.. I remember seeing a picture of the older model and it was goofy looking.. Maybe fitment issues?.. Or performance issues?

I'm also going to buy their 2.5" cat-back, I emailed them for pictures of it, so I can get a feel for the muffler and ****, but no email back yet.

dan is pretty busy, should have pics online though
as far as changing it, we talked about that today haha. he said that they werent really selling any of the first model just because they werent deep into the balt market yet. he tossed the jig for it and then a few years later when they decided to start making it again, they redesigned it a bit. he said it should give any diff in performance as far as changing it up. no fitment issues with it and its performed great!
