I am gonna be getting a turbo this summer hopefully if the funds work out like i think they will. i would like to get the injen short/cai intake for my car since i would love the extra power right now. also the system i hope im gonna be able to get is the turbo kit that garrett is gonna be putting out soon and with that kit i read that it retains the stock airbox which means i would be able to keep my injen cai with the turbo kit. i dont know if thats how it will be setup for sure yet but do you think i should spend the $250 on the intake and chance being able to use it with the turbo kit? or just wait until it comes out to make sure i can use it?

I say wait, save your money. Once you get the turbo kit, then go from there!

definately wait. when you get the turbo kit, there are plenty of other mods you wil want/need to do to get the performance you need. I am not sure how the kit is set up, but it would suck to have spent $250 on an intake you may no longer be able to use. Plus, I'd honestly be worried about other things than the cai if you're getting a turbo kit. Things such as tools to monitor air/fuel, boost, fuel press, oil press, also issues of getting in more fuel and spark with the more air the turbo will push out. just make sure you know what you're doing if you're going to spend the big bucks.

that may be a good idea, have u heard of the setup the garrett kit is gonna have? It seems like a nice kit i saw some pics on urban racer a couple days ago...

i plan on getting 3 gauges- egt, boost, and oil pressure. i hope a 3 gauge pod comes out pretty soon i saw some talk of one a month ago but not sure how its coming along. i def wont want to use the stock air box with a nice turbo kit but if i can enjoy some extra performance now ans still utilize the cai with the kit thats what i would wan to do, i am planning on getting a 2.5 inch catback exhaust in feb. so that will give me some extra kick too until turbo .

im in ur same position, i want a CAI but as soon as a f/i kit comes out im gettin it, so it would kinda suck to buy an intake and have to get rid of it after the upgrade. so i decided to wait and spend the intake money for other stuff

well im happy that the garrett sytem may use the stock air box so that i can enjoy some n/a mods before the turbo comes ill have to get into contact with garrett and see if they can give me a definate answer on if the kit will retain the stock box

this is the kit i hope to get...

Garrett Turbochargers



Judging by Ron Lummus' six-win performance in the Turbo by Garrett Pontiac Sunfire Hot Rod drag car, Garrett might be just a wee bit familiar with the GM Ecotec engine. Though it might not make your 2005 Cobalt LS coupe and LS sedan dip into the 7s on the drag strip, Garrett's new turbo kit for the 2.2-liter Ecotec will push horsepower figures past the 200 barrier. Garrett rep Ainsley Hyman was exceptionally anxious to show us the new bolt-on kit built around Garrett's dual ball-bearing GT2860RS "Disco Potato" hair dryer designed to spool quickly without sacrificing flow up top. Along with the turbo, Garret includes a front-mount intercooler, plumbing, manifold, blowoff valve, piggyback and everything else necessary to make the bolt-in unit work. It even retains the stock catalytic converter and airbox and is schedule to be released in early '06.

heres a link to the pictures of it on the engine just scroll down to where it says garrett turbochargers

^^ It looks like a very well thought out turbo install.

I'm happy that this is available you the Cobalt. Should be a real screamer..

Nice, but will that work on the 2.4L VVT? It only mentioned the 2.2L.

my thoughts exactly ;)

Nice, but will that work on the 2.4L VVT? It only mentioned the 2.2L.

these engines are almost the same with very samll differences, 2.0,2.2, and 2.4 so if its made for the 2.2 then i will make it work for the 2.4

GOOD NEWS

I talked with Kyle at honeywell/garrett technologys and they are working on the 2.2 car right now and he said the 2.2 and 2.4 arnt much different so it should work ok. He verified with me that the stock airbox will 100% be used with the kit and getting the intake should be fine to be used with the turbo so i will be enjoying a CAI before i enjoy my turbo. I just figured I would let you all know.

good stuff. good luck with the car and keep us posted after the turbo install. i wanna see how it stacks up against an SS S/C

i will definately keep you posted also i might actaully go dyno this car after i get the corsa exhaust 2.5 inch and the injen short ram then before i turbo i will get some track times then install turbo and dyno and track again to see results

exactly how would you retain a cold air intake or stock air box with a turbo kit. The intake piping would be coming from the turbo with the kit so the routing would not be the same.

i dont knoe exactly but call garrett and ask them how they did it, they told me i will be able to keep the cai with little modification so it should be good

well i got the intake so we will see what happens here with the turbo install ill make sure ill find a way to keep it even modified

how much is the turbo kit? I'm still debating if I want supercharged or turbocharged

Well it should be about the same as the super but i wouldnt get the supercharger from gm cause it is not intercooled or even aftercooled. The Garrett turbo can crank more psi with the intercooler and the "disco potato" turbo that is going on that kit is sick as hell and has almost no turbo lag. Imagine pulling up next to your neighbors srt4 and smoking the shit out of him in a cobalt ls. :lol:

yeah im hoping when this comes out it will be in the area of $3500 but we will see, whatever it is im sure will be worth it.

You can make a custom charge pipe to route to where the original pipe WOULD/SHOULD be and then use a CAI kit and mount it like as if the unit was right where it should be.

superchargers are cool but if you want big power from a 4 cyl engine turbo is the only way, if you are happy with moderate power then a supercharger may work for you but the sound of a turbo is much nicer to hear than a whine imo

i'm pretty sure thats what garretts kit is gonna include since thier kits retain the stock airbox a cai should be able to be retained as well

i just bought the corsa touring exhaust too so now im all set for this kit to come out

Correct me if i'm wrong but @ 10.4:1 compression ratio that's too high for F/I so you'll need a thicker head gasket to drop the ratio to 8 something...

it is high bit it can be done with moderate boost on stage 1 at about 6 psi which with my setup should net me about 220 whp until i can do tranny and intenal and fuel mods it will work fine

that doesn't make any sense at all, the intake piping will be coming from opposite sides of the engine when you are talking NA vs turbocharged. With a CAI you could route the piping to go down into the fender where a CAI normally goes but there goes your Injen intake that you just spent $220+ on. And even with a stock airbox the whole box and piping would technically be facing a different way but whatever, I'm just being picky I guess. :)

hmmm...unless you know a way to raise your compression to like 9.5:1 or something, i don't think it's worth all that money. 6psi = poop. with stock internals and trans/drivetrain (maybe clutch upgrade) you could run approx 16psi and push closer to 250+hp with little to no mods. the only reason these turbo kits give you such low output numbers is because they are running super low boost. if you don't have the right compression, you can't run a decent amount of boost and essentially waste your money. I'm sure there is a headgasket out there that will give you the compression you need. but i'd seriously look into that first!

Werd, Big Intercooler, 91 or higher gas all the time and Low Boost... Heat and fuel management will be very required to limit the chance of detonation at such a high compression ratio.

It will scream though, High compression and mild boost is more powerfull, just easier to blow up...

well, i think i will be very happy with low boost and high compression for a while. it will be temporary only though since i cant boost higher than that even if i did lower compression becasue the transmission still needs reworked to handle more power so first i will get teh turbo kit and put that on with lots of tuning done before running hard, then i will work on the transmission then i will do internals...220 hp should be good for me for the time being while saving to do all those things

9 months huh. I am waiting to here it's twins!

twin turbos!

Is it an AUTO?

yes it is an auto just like gm's race cars are auto...

Wow, I don't know if it's just BS or if there is some truth to the matter, but I think Autos dont like HP without some serious work such as Cooling and Torque Converter upgrades..

there is truth to the matter, check up on gary gardella that races a red cobalt in the nopi x box cup hes one of the fastest cars on there and he uses an automatic, its true that auto need alot of work to be bulletproof in high hp applications and i plan on doing the work like half cent is doing for around $3500 which is worth it to have perfect shifts everytime i race and never worry about misshifting but the turbo will go on with the stock tranny at first and i will limit the tq to 200 pounds until the tranny gets reworked and the internals are done, its a long and expensive process but a fun one.

Great, I wasn't insulting, I was just concerned that it was not part of the original plan...

:cssNET:

i know , its cool, no insult taken just wanted to explain my plan

has anyone considered ordering a ready built tranny? I mean one thats rated for say 500HP to the wheels? I know there are trannys pre-built to these kinds of specs. I wanna know if I could fit a 4T65eHD under the hood of my bad boy ;)

Most Stock Manual trannys can handle 400 with Clutch and driveshafts...

give me a link to this tranny and ill consider it

Would any ecotec piston work or are they specific to each engine ie 2.2, 2.4, 2.0

Yeah, Oh, not Built at all... :lol:

if you buy an automatic Cobalt and build it up you can be fast like Gary Gardella

i know you were trying to be sarcastic but thats cool, it was just an example of an auto cobalt its not all bad, its prefence and bank roll really, ill never run 7's i would like to run a nice 11 if thats possible with 400 hp or so, i guess we will see

I dont' actually have the link anymore, had to wipe my computer a while ago and lost the info, sorry guys. :(

On another downside... I remember the price was around 5K USD :cussing:

wow thats alot for a tranny but ill just go the way halfcent went since thats all the power i need anyway

sorry no harm meant, its just that when I hear people say they're going to build a car with an auto tranny this is what I think they are picturing having in their car. :lol: Some 3 speed drag tranny that cost more than their entire car.

no i dont have that ricer mentality my plans are all very feasable

well good luck to you, I'm sure it will be a challenge but if you're willing to take it on who am I to discourage you.

well im waiting to see whats going on with the garrett kit, if that falls thru what i may do is have a kit custom made if the price is in my range but i still need to wait for an aftermarket piggy back ecu to be made available for my car. i would really like to use the greddy ultimate e-manage if they ever make that work for our cars, that is a nice system
