I got this from the garret website.Its designed for the 2.2 though.It comes with no piping which is good cause you can make your own charge pipe to work with the 2.0I dont see why it wouldnt work.The only thing is that the turbo is a t25/t28.You think thats too small?
For $1900 bucks,i dont think its a bad deal.

It's just a turbo and manifold...it's not a full kit.

But to answer your question, yes. The 2.0 LSJ and 2.2 L61 have the same bolt patterns for the exhaust side, so you can bolt on the manifold and the turbo of course can go on the manifold.

To answer your other question, the T25 is VERY small in my opinion. Look for a Hybrid Turbo or look into the New GT Series turbos (GT32, GT30). Go to www.turbobygarrett.com and you'll see what I'm talking about.

 

The turbo is a bit small but the cobalt 2.2l turbo kits will partially bolt in. You can always put in a larger turbo if you wish. Your going to need to do a lot of customizing and some pipe fabbing but it will work. Also custom tuning will need to be done. There are a lot of threads on turbocharging a 2.0l. Look around you can see some of the ideas other members on here tossed around.

 

I have no idea what a t25/t28 is, but in DSM terms a t25 is a stocker for the 2nd gens, and a t28 (well it's called the big t28, stock housing w/new bigger wheels) is a forced performance turbo that's similar to a faster spooling big 16g (old but decent size turbo).

 

If i were going turbo i would get the 28rs disco potato! I wonder if you have a option to upgrade bigger on their site?

 

From Garrett's website:

The GarrettŽ Chevrolet Cobalt Turbo Kit is for the 2.2L Ecotec engine for LS coupe and sedan model years 2005 and above. A GT2860RS "Disco Potato" ball-bearing turbocharger and all of the necessary components are included to complete the installation in your own garage!

You could probably make a fun street setup with that turbo, but it's a little small for what I would want.

 

Damn they are using the disco, **** i would just use that.

 

Well, I must say, it is ball bearing and good up to 360hp. That would probably be the way to go if you wanted to save money and have a good product at the same time. Plus with the T25 flange and the ball bearings you could tune that thing to make some power DOWN LOW.

 

Yea exactly dude, just get a shop to fab up some piping, tune, 60s, bov, oil lines, boost controller i would be set.

 

From what i hear the disco is a very good turbo.Do you think this turbo will run out of breath on the top end?You think im just better off just getting a manifold with a t3 flange and just go custom?Im not looking for crazy horsepower numbers.300 will be fine with me.You think this kit will net you 300 hp to the wheels?

 

Only real way to know is by looking at compressor maps

 

Yeah. Garrett says it's good to 350hp; we would need to check the map to see where that is in it's efficiency range.

 

I dont know how to read those maps.I never understood them.Heres the compressor map,what do you guys think?

 

ECOTECForum is your friend

http://www.ecotecforum.com/forums/showthread.php?t=1868 <- Granted it's talking about the 2.2 but it's basically the same as far as the valvetrain head flowing characteristics.

I used the pre-calculated numbers from a Mitsubishi Eclipse with the 2.0 DOHC engine. Assuming the "default" head efficiency (85%), intake air temp (77* F), AFR (11.5:1), intake air after intercooler assuming water to air efficiency (~140* F), and CFM provided by an engine of this size (This will be roughly the same); using a low boost level of 14psi at a pressure ratio of 1.95, and a high boost of 24psi at a pressure ratio of 2.63 (This is subject to slight change depending on compression ratio), the results for the disco potatoe come out to show that it would still be in it's efficiency range at around 15-16psi at 6500rpms.

This shows that the turbo is a little small if looking to reach power levels above 300HP, maybe a bit less. It would be a good street turbo, really zippy, but it would run out of breath slightly at higher rpms.

Edit: Keep in mind these are rough numbers. They could change depending on what boost you use, what your compression is, what the intake air temp is, head efficiency etc. etc. The setup would be good, but it should not be used by anyone who wants a ton of power; this setup should be used by someone who wants a fast street car that could cross over to the strip just for some fun.

I hate guessing numbers, but I think you could run around 280-300WHP (Give or take, once again depending on setup) fairly efficiently and have some really nice power even down low considering the size and type of turbo. It would be worth it for guys who want to make what appears to be around the max amount of power the M62 can put out, without having to worry about your car all of the time and without having to spend ass loads of money on cooling modifications.

 

That turbo will run out of breath...the gt30's are more suited for our engines. The GT-3076 is my recommendation.
I like the manifold....a lot.

 

I would go with a GT30 as well over the GT28. You could use the GT28, but I don't think it would satisfy the jump in power that someone doing a turbo swap on this car would expect.

 

very true...

 

I agree...

 

Cool,thanks for your opinions guys.I see the gt3076 is available with a t25 flange.If i can get my hands on just that manifold,ill def look into that turbo.You think garrett sells the manifold separately?I cant find a manifold anywhere.All i can find is the ebay one.

 

Actually

The T25 might have a 4 bolt rectangular flange which is known as a "T3 Flange". It's very popular and makes it very easy to swap over turbos if you ever wanted to.

 

you know this brings up a good question if the oil lines can be run the same you know from the same point mainly im talking about the feed line for the turbo

 

Do you mean compared to one turbo to another?

If so, yes. The source should still be fine from wherever you decide to tap it and as long as you clock the turbo so that the feed port is pointing upwards, it should be in the same location.

 

Looks like it could definately work but that exhaust flange looks a little small.

 

Im not thinking about this turbo setup anymore.I ended up ordering the ebay manifold.Im having him weld the flange on a different spot of the manifold so i have more clearance with the firewall.Im heading to the machine shop with the s/c and throttle body to have a throttle body adapter made up.I dont wanna be limited with that small turbo.i want a top end beast,lol.
