ok so i know my 08ls is auto and will never be quick quick. but im looking at a header and downpipe and a possible tune. i have the k&n intake and GMPP exhaust. but am not sure which option to go.
what would be a better thing to do. im going to only do one of the 3 things and than be done for performance
here are my options
a) zzp downpipe tune than done
B)ZZP downpipe than a header that isnt compatible with SAI tune than done
C racing solutions header and downpipe combo that is compatable with SAI tune than done.

also after i do whatever i decide what do you guys thing i will be pushing.

 

boost it

 

i would but dont have the funds or a decent payimg job to do so. or a beater car so therefore no builds can happen. i would get a ss but my parents wont let me or anything so yea

 

sucks, then i guess just give it full bolt-ons for a bit more power

 

yeah. so what option do u think i should go with??

 

i say you do A)
i would say you get the 2.4L intake manifold and 2.4L Throttle body and then tune

 

cams? spray?

 

your mom!!! jk man deff keep building it you will be happy when its set up the way you want it!!!! i say boost it and tune it and get tires!!!

 

not doing cams or major stuff like that. and not intrested in spray one bit.

 

was looking into those 2 also.
but is buying those 2 and a dp and or a header even worth it for my car?
i i get all 4 or just 3 or 2 and a tune what kind of numbers will i have??

 

do you wanna go fast, or do you want a ok car?

 

go to school, get a real job, and then buy a real car would be my suggestion

 

well i even had a fulltime job n **** my parents wont let me sell mine as of now and get a SS or anything else bc of payments id have to make and **** like that.
i wana trust me i would of a longggg time ago. but there gay bout it so w.e

 

im not going to break 200 i know that. but just little faster than what i am.
i cant do major stuff or **** like that but little stuffl ike header dp 2.4IM and 2.4 TB and a tune is stuff i could do.
id prolly do all of that or part of it than be done bc a build isnt guna happen

 

if you do full bolt ons I say you'd be around 160-170

 

yeah. i think all i may do is zzp downpipe and possibly a header and a tune. i want a zzp downpipe but than if i go to get headers im guna have to get a set that isnt made for sai which ill deff need a tune for.
or i could go with the racing solution header dp combo but i really want a zzp dp

 

lookie found this for ya

If your confident you don't want to do a F/I build or a serious NA or nitrous build but want some more power, do all the bolt-ons available then tune. I would definitely replace the stock exhaust manifold and downpipe. If you're on a budget get an LSJ exhaust mani and a ZZP (you seem to like them) auto downpipe. Do this BEFORE you purchase a tune. If I wasn't super charging and only doing a mild na build I would have I/IM/H/DP/CB installed first. Then buy the 2.4L TB and tune at the SAME time (you cant run the larger tb without a programming change) then be done. You can find LSJ exhaust manis cheap and ZZP actually makes a dp for the autos (it is physically different than the manual version - longer) or any other DP so long as it is not the stock lsj dp. I don't know why you would only do a DP or only do a header. I would do both....

Have you been on a dyno in stock form or now? Total shot in the dark guess for your setup after bolt-ons and a tune would be 140-150. You'll probably be on par with a stock MAYBE mildly modded 2.4 cobalt.

 

thanks for that link. i think if i was to break 160 ish or so id be satisfied.
i just dk if i wana do the 2.4 throttle body. i deff want the manifold and im still unsure if i wana get a header or just run the stock header with a zzp dp and maby eventually get a header to bolt to the dp or just get the rs header dp combo since it works w sai

 

yea i heard the lsj headers wont work woth auto's.

and yea imnot going f/i or anything i dont have thefunds time or another car to drive to do it. well i hve money to buy a legit kit i just cant bc ineed it and stuff. my cars my only dd.
and no i havent been on a dyno yet. all i have right now is intake and exhaust i wasnt sure if dynoing would
be a waist of money or not

 

People with autos run into issues when they use the LSJ DP mainly. The header will bolt up fine (on an 05-06 for sure) and so will the DP actually. The LSJ DP is shorter than the autos DP thats were the problem is.
On newer 2.2Ls you might have to make a slight modification to the head or the header (I forget which) but it can go on, people have done it

I wouldn't dyno before either tbh lol. You definitely can just do a header or just a DP but when you look at the goal it doesn't make any sense (unless you plan on doing both in the future).

 

ok, got ya

 

you>me

 

yeah.
what setup would be better. a zzp dp and a normal header that will need to be tuned for my car or the racing solution header dp combo that is compatable with SAI so i wouldnt need a tune.

 

You technically don't need a tune either way. I know you'd need to turn off the CEL to pass inspection though lol. I would recommend a tune either way tbh, that's how your going to get the most out of your mods. I would also recommend the tune because in almost every case here that I have read, people that have autos say that the car "came alive" after the tune because of mods as well as some tweaking to the transmission settings.

If you get the ZZP DP and an LSJ setup you would have a shorty+DP. I've been told for a supercharged cobalt that midlength and long tube are desirable. I don't know if this hold true for a mild NA build or not or how each affects where/when you make power. In terms of bang for the buck (on the less expensive side) the LSJ mani and zzp or XTC dp is prolly your best bet. I'd probably get stainless equipment if possible..
