guys the stage 2 gm upgrade isnt enough power for me, so i hear the next best thing is the header and downpipe, are the OBX header and downpipes on ebay any good?

 

Im not sure the only one i have seen have been for the 2.4 although they are the same header I dont know if the downpipe is the same. I try not to buy of ebay and I have used obx parts I wasnt too thrilled.

 

are the power gains from the header and downpipe all they are cracked up to be?

 

^ It is all part of a process, you may not feel any gains with them, but as you keep adding other parts, the power adds up.

 

well like i said im pretty pissed i got a modded intake box and stage 2 kit, i cut off the resonator on the car also and im getting destroyed by my cousins mk5 chipped gti....very frustrating haha

 

When I went from stock, to stage 2, I was not impressed either.

 

Well the gains are decent, you can tell a difference with the butt dyno but it is still minimal. You can feel a difference with the butt dyno but a good tune will go far. I have the ZZP Stage 3 installed on my car and it seem to work awesome after a little bit of driving. Another thing is dont go cheap with the fuel get the highest octane you can find atleast 91-93 octane.

 

yea i really thought it was gonna be quicker then it is, its def not running 230 hp to the wheels thats a phony number

 

I would not add a chip..

 

na i was expecting the header and downpipe to kind of shoot me up in power but im actually considering just getting rid of the balt and getting an mk6 gti

 

I have a header, and a downpipe is on the way. Honestly its like that other guy said, you might feel a little power.. a little.

 

I thought I was still in the 2.2 forum no chips for the SS custom tune FTW!

I want to add a TVS Shortly thats a little more cash then I'm looking to spend at this time though.

 

I would not buy any performance parts off ebay, you get what you pay for in the car world...

 

They have that polished tvs for sale now, I want that one.

I dont have $2,500 though.

 

yea i think im just gonna go ahead and sell my balt

probably try to get 9500 for it

 

One thing I will let you know is that it's a lot on the drivers parts you can have the fastest car but an unskilled driver with the fastest car will lose everytime. No thats not a bag on you, because I dont know you or how you drive. This is just something I have picked up over the years the cobalt is good car with a good and cheap aftermarket you may think of going thru zzp and ordering thier stage 3 you will definately see a difference.

Im not fond of polished I prefer the black powder coat.

I think with my current setup im at about 260ish possibly. I still have to go to the dyno.

 

What tune do you have?

 

The ZZP Canned Tune with Intake and Full Exhaust thier dyno sheets show 260 and it feels like it my 350z was putting out about 250 to the rear wheels and after driving both they both pull the same I need to get to the dyno and see what my actual numbers are.

 

the stage 3 zzp kit will bolt right onto my cobalt with no problems?

 

No problems and its cheap it took me all off about 8 hours total because I went with the stage 3 heat exchanger and had to pull my bumper off that kind of stuff and on top of that I had never done it before it worked out pretty good. I only paid 571 for the kit and the tool to remove the pulley. You would have to remove the gm stage 2 hub not sure how hard that would be but it would be worth it.

 

are we talking good power gains? this is interesting

and would i have to re-tune it, because im in north jersey dunno anywhere to get a good tune around here

 

You should have just gotta a ZZP stage 3 w/ the H/E, bought yourself a header/DP combo, threw on a intake and got it tuned. Then you'd be impressed over stock.

Im not installing anything on my car until i have all the pieces in my garage. I have the Header/DP sitting there, just waiting for the ZZp S3

 

Good power gains even on the canned tune from zzp. You would see even more on a custom tune.

You can get the canned tune from zzp just send your computer in to them. Its a good base to start with for a custom tune.

 

i know i regret getting the stage 2 gm kit, but maybe if i just find a place and get a serious tune instead of the BS one that gm does ill be happy

 

With the 3.1 pulley your luck to see 13 or 14 psi go with the 2.8 and 60's you like the power that and the mileage got better by about 4 mpg.
