I am going to be buying a 2005 cobalt ss supercharged here in the next few days. However before i do i have a major question. I've seen turbo kit after turbo kit for the 2.4L and the 2.2L but not a one for the 2.0L besides the stock GM kit. And another kit that adds a small 140hp for like 4k bucks.

I will be getting a supercharger delete kit.($215) but i'f i'm not going to be able to hook up an aftermarket turbo to that 2.0L engine and be able to get to 350-400whp or more then it will be pointless for me to buy the car. 260hp WILL NOT SATISFY ME! anyways. if you know of a kit let me know. or if you know there isn't one out there that will do what i'm looking for and i will have to make my own let me know. because i'm fine with doing that. just as long as it will work on the car.

260hp WILL NOT SATISFY ME!

You're buying the wrong car, then. Why not the new Cobalt SS/TC?

cobalt SS/TC is the way to go it want a cobalt.

The supercharged cobalts are fail. If you are looking to spend that much money, I have to go along with the above and say that you might be better off with a new turbo Cobalt. They have some pretty sick tuning potential too. All for about $24,000, not too bad.

Why not? The 2.4 liter N/A LE5 has significantly more potential for tuners than the Supercharged LSJ. Yeah - the LSJ's a lot cheaper/easier to get a 13-second 1/4 mile out of, but the LE5 will yield 12's with a turbo and computer tune, a little more than a $3,000 package. That's why GM's dropping the S/c Cobalt in favor of the N/A. Anyone who's tuning significantly are either ignoring the 2.0 supercharged entirely, or gutting the supercharger, putting in a block-off plate in place, and turbocharging it.

The LSJ, while, not a bad motor, is lacking in certain respects that would make it an overall great motor. The LE5 has a bit more room for its VVT to phase, making it more versatile, the LE5 has a bit more room for changing the stroke of the motor, (de-stroking it down to a combined loss of one tenth of a liter brings the 173 peak horsepower down to around 165, but extends the powerband from 3400 RPM to almost 6900 RPM, making it quite versatile.) So, to de-stroke it to 2.3 liters and turbocharge it out, would yield a more versatile engine and frankly, a much nicer platform for any kind of racing involving 4-cylinders than the LSJ.

The 2.2-turbo drag motor used in pro-stock is an LE5 de-stroked from 2.4 to 2.16 liters, turbo'd, meth-injected, and has a redesigned valvetrain to put up with the 15,000 RPM redline, and 1400 horsepower that it puts out. A common mis-conception is that they start with the 2.2 and de-stroke it to 2.16. The fact is, the 2.2 has different coolant routing, making it less efficient and effective. While it is possible to build the 2.2 up to 1400 horsepower, as per the GM build book, the LE5 is the motor used when you buy the "performance crate motor" referenced, and it's quite a bit more reliable at 1400 horsepower than the 2.2 block is, thanks to its coolant routing. Basically, the turbo 2.16 you buy is a pre-modded LE5.

Believe me, I love the sound of a supercharger just the same as the next gearhead, but for engines this small, the parasitic loss just makes it useless. A turbo just fits so much better, and a properly designed turbo kit is just so much faster/more efficient. (Example, the LSJ turbo kit makes 21% more power on the same amount of boost as the stock supercharger.)
so f*ck the supercharged Cobalt.

Correction...just found out they must have some incentives on the new Cobalts right now, you can buy one for less than that now. I thikn it's an additional 2500 off.

yeah... i guess nobody saw that i was going to TAKE OFF the s/c hence buying the supercharger DELETE kit. I know the s/c is crap for the car. Why would i buy a new SS t/c for 20k when i can buy this 05 s/c with 28k miles for 10k. hell i could make it the new one for like 3 grand. but that's stupid. I guess i should have just asked, Can i strap a turbo like a GT 28 71R or the slight step up GT28 76R? I mean those will both get me to my 400whp goal. I mean i don't even need 400whp. I plan on making this a car i can go down to the strip in if i want... or i can take it on a road course. i dont want 1400hp on a frikkin road course. or on my daily driver.

another reason i don't want the 2.4L is beacuse they don't look as good. and that would just be more money out of my pocket to buy the parts i need to make it look like the s/c or t/c coupe. maybe that will clear some stuff up.

atleast i hope you understand that buying a new one would be stupid because i could make my own new one with this 2005 cheaper than actually buying the factory T/C SS.

The LSJ lacks cam phasing, direct injection, launch control, no-lift-shift, and the older SS has a much crappier suspension.

And - no - you won't see 400 WHP out of even a turbo'd LSJ with a supercharger delete. At least not reliably. The LNF I4 > LSJ I4 stock, lightly modded, and heavily modded. There's nothing you can do to make the LSJ better than the LNF in the least bit.

I still say go with the LE5, turbocharge that instead, and go from there. Hahn Racecraft is seeing 420 WHP with ease out of an all-stock bottom end, and mostly stock top-end from those engines. The LSJ topped out at 330 WHP before reliability (turbo or supercharged) started going out the window.

If you get the LNF Cobalt (Turbo), you're looking at an easy 400 WHP with an intercooler change, a bump in boost, an ECU tune, and an exhaust. Want more? New injectors and another ECU tune. You're approaching Nissan GT-R power generation, out of a two-liter 4-banger. Want more? Get a real performance car.

You won't see 400whp on a GT28 untill it's very tip top and unuseable.

I have a feeling this guy just posted like everyone else as of late to get a pat on the back and nothing more. All suggestions have been whisked away for his way.

i still wont find the t/c cobalt in the price range i'm lookin for. i mean i can afford one. but that will take money away from my project car. the big thing with the LE5 is that i just don't like the look of it. and i don't wanna have to drop a couple grand to make it look like the s/c or the t/c. and i'm going to replace the suspension if i get the s/c ss. and i will be replacing transmission parts as well. anything i need to replace to make it run safely i'm going to do. which i would still have to do with a new t/c ss. which in turn cost me more money.

Wow.......is this guy serious?

i'm not asking for a pat on the back. if there is no way in hell i can get atleast 375whp with the s/c ss then i can accept that. i'll have to resarch and see what it will cost me to buy the parts to make the ss n/a look like the s/c though. otherwise i'll just find a different car.

WTF does is matter how the engine looks? How "good" and engine looks has NOTHING to do with it's potential....

Sounds like you want to be one of those ricers who puts a bunch of chrome crap in the engine bay to "dress it up" and not get any power from the shit.

i'm talking about the body of the car.... not the engine. and it matters to me what the car looks like. i dont care if a rust bucket will run a 7 sec 1/4 i'll never drive it. that's just the way i am.

Wow......so take the body kit from the SS/SC and slap it on a SS/TC or LE5 engined Balt.

Who cars what the body of the car looks like....like people will be seeing you making 400whp and saying...it's nice and all but I wish it looked more like the SS.

Or just get a DSM.

:dunno: IDGAF what a car looks like if it's fast, quick, and reliable.

no...this is the first 4 banger i'll own. i've had an 05 cts 3.6L, 07 1500 silverado 4.8L, 03 GMC 2500HD Duramax PPE programmer running a 220hp tune, and now i'm selling my bad buy a 1994 camaro z28 covertible. so no i'm not a ricer. i likie big engines. but if i can get serious power out of a 2600lb car. **** it i'll do it. plus i can stick with my american cars. but no. i was not at all talking about dressing up the engine bay. i was talking about wanting the body kit that comes on the ss s/c if i got just the ss n/a.

I'm sure you won't have any problem finding a S/C body kit for the N/A car.

Gte a DSM. Cheaper to go 9's and proven...PLus you can buy a 1g and go 9's for $15,000 including the car.

:dunno: IDGAF what a car looks like if it's fast, quick, and reliable.
Nice to know. but i said that I AM like that. I like a car that looks good and is not just fast.

than keep your Camaro, TT it and stfu

What he said works, too.

I'm sure you won't have any problem finding a S/C body kit for the N/A car.
I mean i probably wont. it's jsut how much it's gonna cost. cause i'm gonna put most my money towards the performance, but as i have said plenty of times now. i wan the car to look good. and i think it looks better with the s/c body kit. It's just something i will have to look around for and check pricing.

than keep your Camaro, TT it and stfu

the LT1 in it is slow as ****, the tranny is about to go out, it's an automatic, the top leaks, it weighs 4400lbs since it's a convertible. in other words.. its a POS.

I don't get these people...The come in here and ask for suggestions than say no you're wrong or no I have some other ridiculous variable and don't accept you suggestion and nothing is resolved....Why...what's the point of you coming here than telling everyone no? Just inflating that ego or what?

everyone is telling you not to get the LSJ than the LNF is better....you don't want to listen and you say oh well I can afford get a new SS/TC but I don't want to I want to reengineer a car cause I am cool like that. Than you do reengineer a built to be supercharged car to run a turbo and get 400whp and end up spending MORE in the end than you would just listening to us....

i don't want to spend 20 grand on a car when i am not only going to be buying parts for the cobalt. I'm buying a rolling chassis 1970 olds 442 that i will have to put money into so that it's not just sitting. my paymet for a new ss t/c would be twice what the s/c would be so that means less money towards the project car. How hard is that to understand? but if the LE5 is actually the best one to buy then i can deal with that. I've found 2 or 3 of them. bu like i've said the only problem is that'd i'd have to put into the body and not just into performance.

so forget the Cobalt and focus $20,000 to your olds...You rave on here how you have 13 cars...why have more?

Does anyone else see the sheer stupidity or is it just me? Also....who wants to bet he's 16? Any takers? I think daddy might have a nice selection of cars.



*Edit* He's not 16...he's 20. I bet they are Daddy's Silverados CTS and what not.

LOL, probably so, x, probably so.

X???? Am I the new X to the Z?

:facepalm:

i'm 19 i'll be 20 in sept. daddy bought the first car. i've paid for the rest. i don't have all those cars anymore. those are cars i've had. the only cars i have now are the diesel and the camaro. i sold the diesel to my dad recently and bought the camaro(bad choice) i've just got a new job where the first 3 months i'll start out makin 1600 a month then after that i'll move up to like 1900 i've only got a little over $300 in bills right now so i figure why not buy a new daily driver and a project car. the olds is gonna cost a grand and i was gonna buy an audi tt quattro coupe but decided any kind of repairs were gonna be ridiculously priced and if i can make a cobalt ss alot better than the audi then i might as well do that. even with adding car payments to the bill i'll still have about a grand, maybe more, a month to do w/e i want with.

i just know that some car guys here (as in my state) have told me i can turn a 2005 coblt ss s/c into a turbocharged 400whp car. as long as i upgrade the engine, transmission and suspension.

and since you brought it up daddy has had a nice collection of cars over the past few years. but he made the mistake of trading his 06 sts for an 08 gmc sierra 1500 crewcab.

It will cost, in total, including cost of the car, roughly $26,000 to do so. You will need to rebuild the engine, both top and bottom, to accept larger amounts of boost. Expect at least $11,000, including supercharger delete, a turbo worthy of making good all-round power, not just being a dyno-queer... and even MORE cash if you don't do it yourself. You will need to rebuild the transmission, both "hard" and "soft" parts to be able to handle that kind of power. You're looking at roughly $2100 for those parts. You will need stronger half-shafts. $850. You will need to completely redesign the suspension on all four corners to even hold a candle to a STOCK SS/Tc, expect roughly $3,000 in parts if you don't bother to go with wider wheels and more grippy tires. If you go wider and grippier, expect an additional $2,000 if you use the right lightweight wheels. If you get an '05 at a bargain-basement $10,000 in good condition, you're looking at $26,950 if you don't include shipping for parts, labor, tax, or better wheels/tires. $28,950 if you do. You can get an '07 Cobalt SS/Tc for $12,865, do an intercooler, ECU tune, and exhaust, be near that 400 horsepower mark for a total of $24,565 after cost of car and modifications, and it'll handle better/feel better/perform better overall. For both those prices, you could get a used Solstice GXP with the turbo, have it RWD, make the same power, with better handling in a lighter package than the Cobalt, in a RWD vehicle that won't plow through turns with nasty understeer like the POS FWD will.

F*ck, for that price, you can get a 2006 Corvette, cranking out 400 horse, 400 ft-lbs of torque in a 3100 pound package with a 6-speed manual gearbox, and an infinitely better overall vehicle, BONE STOCK.

Whatever.

okay then what are my essentials and prices for the LE5(cause i've found an 06 for like $10k with 40k miles) if i want a 400whp road course car? or can i not do that either? if you don't know prices then what are some good brands? i just need to know what to do to get the car to perform that way the cheapest. but not with like crappy parts of course.

*F all that. What car can i buy for 11k bucks. i want it to be fast on the strip and on a road course. doesnt have to be top dog on both though. and what will i need to buy to get the car to be both a fast strip car and a fast track car?

For road courses, you do not, I repeat, do not want a FWD car. They're extremely prone to understeer. But if you're absolutely dead-set on a Cobalt, and absolutely dead-set against the turbocharged SS, you can get an LE5 turbo kit from Hahn Racecraft that will push you to 300 horse for $3k, and another $1k in modifications will get you to your 400 horse mark. You will still need to rebuild your tranmsission to handle the power. You will still need to do the extensive suspension modification to keep up with even a stock Cobalt SS/Tc. Your best option is a 2.4 Solstice with a Hahn Racecraft stage 4 (http://www.turbosystem.com/ProjectVehicles/New_Folder/SolsticeStage3pdf.htm) turbocharger kit. On a little over 16 PSI through the turbo, they're hitting 373 RWHP, 375 ft-lbs of torque at the rear wheel with a longer powerband than most 400 WHP dyno-queen builds, essential for road course racing. Their 373 number is also on a fully stock bottom end with a relatively stock top-end, and just a bit of tuning on top of it. They've been pushing faster and faster since the kit released in 2007, and are in the 11's in the 1/4 on the Soul Food Solstice while being able to keep up with the best in the autocross circuit.

DSM.... Kid doesn't listen at all....

okay so the soltice sounds good. but i'll have to see if i can find one. and no i'm not completely set on a cobalt since just 2 days ago i was plannin to get an audi tt

and idk wtf DSM means...

okay yeah i don't want an eclipse... i just hate them. lol.

DSM, Diamond Star Motors. Includes the Mitsubishi Eclipse, Eagle Talon, and similar cars. They're cheap to make fast, but reliability is questionable. Not saying there aren't DSM's out there that are amazing, but it all depends on how you build them. Most I've personally met do it wrong. Laserspeeddemon here on this forum knows more about the subject than I do, so you're best waiting for him to appear.

ehh i don't like any of those cars so i don't really care to hear about them. so you're saying a solstice is my best bet? anything other than that?

Solstice, Sky, Toyota MR2 (1999+ only. Before that, they suck.), Pontiac Fiero (1985+ only. 1984 sucks.), Mazda RX-7, the list can go on for quite some distance.

okay well what about as far as american goes? and year 2000 at the oldest.

anything with an LS1. :biggrin:

yeah i'm done with v8s as a daily driver. i'm lookin for a little 4 banger maybe v6 that will scoot.

Dodge SRT4

Holy christ with the restrictions.


Next will be, sorry... nothing that has an S and a 4 in it.

Holy christ with the restrictions.


Next will be, sorry... nothing that has an S and a 4 in it.


lol okay okay take off the american part. i just don't want somethin really old. and i just didn't want 1 guy to have to name a bunch of cars. idk but sure everybody that has an idea for a car through it out there!

and okay and SRT-4 i can deal with. i like it. but if a fwd car is gonna suck on a road track... then idk. but i have heard that with the stage 3 or 4? i dont remember if it goes to 4 but anyways i heard with the top stage parts in it they are pretty frikkin quick.

okay yeah i just looked at parts. and holy crap i think i've finally found a car.

This is the best matched turbo for the 2.4L motor for maximum power with the stock rev limiter. This turbo is perfect for those wanting to make big power on pump gas and win just about any street race from a roll. Full boost should be right around 3100rpm in a .48a/r turbine housing and 3500rpm in a .63a/r. The difference being about 30-40whp less when peaked out on race gas for the .48a/r, but with the faster spool the .48 is nicer for pump gas street driving. On our test cars, we've pulled over 420whp on pump gas at 23psi. The maximum boost is around 30psi where we have seen 500+whp with the .63a/r. The ballbearing option is really nice on this turbo if you can afford it but when combined with the .48a/r will surge a little under high load low RPM conditions.

We have released a ceramic ball bearing 50 trim turbocharger that gives you all the same features as the 50 trim we've become to love, now with quicker spoolup. Ceramic ball bearings provide less rotational friction that will allow for quicker initial spoolup, and better transient response. If you want everything, get the 50 trim Ball Bearing. It's an extra $500 on top of the $1900 base price, but if you want the ultimate spoolup characteristics, it's worth it. New water lines are included in the price.

can someone explain some of this?
