Looking into a Cts-v

[07cobaltss/sc]

I've been thinking about getting a 05-07 Cts-v in 6spd and was wandering which year you guys would recommend and the ls6 or ls2? Are the clutches strong? Any typical failure on the car?
Also what kind of 1/4 mile times and Dyno numbers to expect from Cat-back, Intake, and dyno tune?
also is the stock cat-back piping already big enough or should i replace that too when i put on another muffler and resonator?

Thanks for reading

not gonna start with ls6 vs ls2 debate you can search that,

-a stock clutch is a stock clutch no matter what car, you throw power at it it isnt gonna hold
-stock car will put down around 340rwhp and with a catback, dyno tune, cai your looking at a whopping 350, factory stuff is pretty good, exhaust is just for sound not really much power to be gained until you do headers.
- the cars wheel hop like no ones business it is not a drag car, but slipping the clutch can gain you about a 13.5-14.x at upwards of 109-110.

wow onlg 13.5 with intake and tune i thought they did 13.1-13.3 stock according to the magazines
why does it wheel hop alot? and ya cat-back im just doing really for sound but intake and tune im doing just for some good gains.
what about ported intake manifold and tb are they the same as off the corvette ls2?

I pretty much agree with Zo6 though some guys have indeed gotten those low 13s in the 1/4 mile. It might be a technique thing, however. But, this car wasn't designed with the dragstrip in mind, IMHO. It was meant to go around corners and brake, too.

It's a gas on the street.

can u put the ls7 clutch in it? and i mean with intake, cat-back, and tune will i atleast hold my own with other cars? like corvettes, srts, mustangs, m3/5, etc.

Take a look in the archives this is discussed numerous times, with both engines, wheel hop, etc.. With this said our cars are not 1/4 mile cars. From a roll we will thump a large # of cars. On a road course we will also hold our own. Unless you overcome the 700lb. difference to vettes it takes more power to beat them. A maggie will get you back in the game with the Corvette boys. Most of the LS mods for engines work the same on our cars as others with the LS motors except no gains to be had with CAI unless other larger mods are made.
Don't want rain on your parade, just wanted to give you the correct expectations of the car.
If you wan't a 1/4 mile car then you need to get the checkbook out big and bad!

Sounds like your pretty keen on quarter mile times for whatever reason. Your probably better off with a rustang if that's the case


These cars are for the road course and also make a great daily driver.

thanks guys, i just dont want to buy a car and not know what to expect

[07cobaltss/sc]

can you put a ls7 clutch in either the 04-05 or 06-07?

Yes. You will need the spacer or a LS7 slave to complete the swap.

Again as everyone else has pointed out ... SEARCH

[07cobaltss/sc]

sometimes its hard to find answers takes alot longer than posting. but thank you for the help.
how do you like your 05? those i can get for like 21-23k

[stars_fan]

It's a typical GM product. You still get the little rattles/squeaks. You get a weak rear end that needs some serious $$$ to be reliable. Oil pressures switches, motor mounts, alternators & memory seat modules love to just go bad (all have failed on my 35k mile car).

Just trying to be realist here.

[07cobaltss/sc]

are the rear ends the same or as strong as each other on the cts-v and z06? but i mean alternators and motor mounts arent that expensive. just seems like normal wear and tear as would on any performance vehicle

[b00ter]

Im also in the same boat, looking at a CTS-V, but am kinda leary of the rear end esp out of warranty, I have no idea what it typically costs to have a new one put in.
