Cobalt SS Stage Kits

[WetSSBolt]

Any one running a stage kit on the 2.0 LSJ? Or have an opinion on what stage kit to get for it?

[fballman1987]

i have the GM stage 2 kit on my car. i loved it at first. then i got used to it. but its def a great kit. they say that the kits are just kind of blah, but you retain warranty and everything.

IMO, it's the best/safest bang for the buck. I got stage 2, and shortly after threw on a 2.85" pulley...the tune is a bit conservative though, and very rich...hence, the safety.

Then again, some LSJ folks out there say the rich tune and our return-less style fuel system leads to unburnt fuel (particularly in the #4 cylinder) washing the cylinder walls of its oil, and *POP*

I've had no problems with mine, and I'm actually quite happy with the results over stock. Shaving 7/10 of a second off of a 1/4 mile for around 600 bucks installed is definitely worth it IMO.

Im looking at the OTT stage kit which seems decent. Its a bit cheaper and seems like it comes with more to do future tuning which i plan to do because my warrenty is already up and i wanna see what i can really do with this 2.0 keeping it supercharged that is. I see alot of people turboing them and blowing em up

Ah yeah, if you're already out of warranty, get a small pulley, some 60# injectors, and a nice tune...then worry about getting that power to the ground. You should be good for 13.5s all day in the 1/4...anything less than that and you're talking drag radials, which will mean axles in the near future lol.

If you wanna go faster, you'd have to work on the valvetrain/head of the motor a bit.

I say check out the ZZPerformance twin charge kit

[fballman1987]

no dont go with the zzp twincharge kit, its a rip off and the numbers are way inflated, they seriously need to retune the car every month. that and YOU have to take the car to them. you cant buy the kit and install it yourself. totally not worth it. if you want serious power just go turbo(3071r should do the trick) mild tune and stock internals will get you about 350whp. there are 3-4 over 400whp cobalts, both turboed. one made 484 on 24lbs with no motor work. people blow these cars because they buy careless parts and get ****ty tunes. the LSj motor will not have the same effect with the same tune, the all individually need their own tunes. go to Cobaltss.net and research a little of the tuning.(the people that own OTT are great and theyve had cobalts, on ran a 2.5 pulley for over a year and then went tvs.) plan mods and dont get a half ass dyno tune it WILL blow up.

The only downside to the 2.5" pulley setup is machining the snout of the S/C, and the ungodly amount of heat that it will produce pushing that much boost. Depends on how far you wanna go with it, but you're right, the guys at OTT definitely know their ****.

And I mean if you really DID wanna go turbo, the only thing you really need to worry about is the head...proven to be flawless up to 350hp, so if you're really worried about it, get new valves and stiffer springs, and that solves the problem..easier than a lot of people think.

I haven't followed much on the TVS since it came out...has anyone done anything crazy with it yet? We have one guy over at Redlineforums that ran a 13.1 or 13.0 in his RL with one, with the pulley that it came with on it, but I think that was with DRs as well, and his previous best with the m62 was a 13.2...

I never go on CSS.net anymore really, once I hit mid-13s in the 1/4 I stopped worrying about making it faster since it's my DD.

Thanks guys. The car is my dd but i travel for work all the time so technically it doesnt get driven daily so i would like to push it hard. For now i think im just gonna keep tuning the supercharger to see what i can get out of it. Ive already got a wet nitrous kit on the car and a set of dr's in my room so ill propbaly start of with the ott kit thien get the hp tuner and the snout that will allow for the 2.5 pulley. I also have zzp heat exchanger waiting to be installed so i shouldnt have to much problems with heat like these cars a known to have worked. Im looking into the wot box now... anyone running them on the lsj?

[WetSSBolt]

Also looking into meth kit. Any kits better then others?

^^Not my car, but a guy on the forums...has his box set to 4 grand (not for launching, but just to demo it for the vid), but I have to say it sounds awesome! Kinda like the dirtbike from the original excitebike game for NES...

He got the version with the no-lift shift feature and said he LOVES it, and it was extremely easy to install.

If you're going 2.5 on the stock blower, the only thing you should need to worry about is heat. I noticed you got the ZZP heat exchanger, but if you wanna go a bit further in to keeping the heat at safe levels, there's a guy on redlineforums (also on CSS.net) who made a single-pass intake manifold, and has had extremely good results and temperature drops. He says you can send him your manifold and $200 and he'll do yours as well. Here's a short thread on what he's got...he couldn't go in to too much detail without needing a vendors license on the page, so read up on this and PM him if you have any questions, or if you're interested. http://www.redlineforums.com/forums/...ld-update.html

I've talked to him personally a few times and he's really helped me out with a lot of things, especially when I need it the most...so I'd assume he's very good to do business with as well.

I'd say you're good for lowwww 13s if you threw the DRs on, 2.5" pulley and supporting fuel/cooling mods/tune, and laid off the spray.

Also im making wes buy the a/w intercooler hahaha

[WetSSBolt]

Yea the wot box just sounds intimidating haha. People are shaving .5 or more off 1/4 times to which is always sweet. I take it you dont like spray dbryden? It is a bit scary on stock internals not tuned or anything but im only running a 50 shot playing it safe haha and i rarely ever use it. I filled the bottle like 5 months ago and it still has some left so i dont abuse it

[SvicksTc]

No just when i make you abuse.....

theres a few guys with TVS that have put down awesome numbers. unfortuneately the general forum public does not know the numbers. i however do. lol. an awesome tuner, laid down almost 350whp on the tvs on stock cams, and upgraded retainers. he makes power all the way to 8100rpms. he de tuned for the winter(lean ness ftl) and is still at 307whp, says he has no traction all the way through 3rd.

another balt, turboed, is daily driven at 411whp, no motor work what so ever, he is trying to blow it up and it wont. the head isnt an issue. its knowing how these cars are going to react and preventative tuning and modding. ie return style fuel system(for good ol #4 piston), meth, bigger heat exchanger, and an awesome tune.(which btw is very hard to find a good tuner)

[WetSSBolt]

You guys know anyone running the Jbody Performance header? It looks sick and they are saying 32 whp out of it but that seems steep

[Buster]

Hey Wes, I think if you are going to run Meth, let go of the N02. Running them both together is going to put that stout little 2 liter down. Keep running the SC. You can still pull decent power from it.

[WetSSBolt]

Oh dont be scared Keith atleast not yet ; ) haha

[Buster]

i dont get it lol

I toyed with the idea of nitrous for a while, but didn't want to risk anything. There's no doubt in my mind that the motor would hold up with a good tune and a 75-100 shot, people on RLForums have done it and dyno'd 320 wheel and sprayed all day...but I just know I would get myself in to trouble with it, and decided to shy away. I've never used nitrous on a car, but just knowing that it's there would make me want to spray alllllll day lol.
