Turbo Kit For 2.2l Ecotec

[02alerogx]

I'm looking to put a turbo in my alero and am looking for a vendor to get a full turbo kit, (turbo, manifold, intercooler, piping, etc.) any help would be appreciated

[xbxradxsx]

Check out turbokits.com and under the 02 and up cavalier. It is a stage2, and says that it may work with the same engine type with minor mods. It also says for 5 speed only. I have an automatic, and have been looking into it myself, trying to ask them questions about it. check it out here (http://www.turbokits.com/cavalier_turbo_kits.html)

yea theres a lot of issues when it comes to finding turbo kits for automatics, once i figured that out i put to rest my turbo project, just because theres not much support for the automatic version of turbos for the ecotec. not to say theres not some out there, but the more upgraded kits are sold for the manual only. check out hahnracecraft.com, and theres another i cant think of.

[FantomForceCustoms02]

Yea hahn racing turbos are good if you have the manual. I emailed them about it and they shut me down cause I have the auto. So now its either a gm superchager that you can only get the stage 1 for if you have the auto or back to my air ride project.

What's the deal with turbos on automatics? What would it hurt? Just wonderin.

wont hurt nothing, theres just a lot of issues in regards to the tuning, fitment and all, if you notice all the cars out there that there are actually good turbo kits for, they are all manual cars. the market favors the manual tranny cars. cant say i know exactly what all it has to do, but thats a couple basics.

[FantomForceCustoms02]

Yea it has to do with they way the intercooler piping runs and where the auto tranny is located, they interfere with eachother too much. I know a guy with the hahns turbo on his cavy and we were comparing the 2. The piping runs from the intercooler, along the motor on the driver side, then behind the motor and back down the passenger side. There is more space there with the manual tranny than the auto.

id say the bigger problem with automatic trannys is the intake to the compressor and the oil return line from the turbo... the piping can be put anywhere you want it... usually to the right of the engine ... above the motor mounts... around the radiator fluid reserve and down through the side wall.... i did a 2.4 motor with an auto with a built turbo equivilent with a stage 4 kit.... the hardest thing was routing the intake casue the shift cable was in the way.... and getting the oil return at the right angle so it clears the tranny and doesn't crimp shut...

holy crap, all you ever talk about is doing this one turbo install and motor build and it is the same damn thing, "i did this one car....dee dee dee....a stage 4......dee dee dee....forged rods and pistons......dee dee dee...." wow you helped with one turbo install give it a rest!!!!!

[natedawg9640]

sorry if my ONE turbo install answers or gives useful input on just about every turbo question people ask on here... if i had a way to mix it up i would... but it works... so i tell it... so shut your ass... and no that isn't the only experience with turbocharging vehicles but it is the closest thing to an alero that i have done... so ... that's why it's the only one i refer to... so yeah it might get repedetive but it works... some time soon i will try and at least post pics so you and everyone else knows i'm not full of poop and talking out of my ass like some people on here... untill then i'd appreciate it if you would keep your bitchin to yourself casue this is a place where people go to share things they've learned and read about things they don't know... :pissed:

i got a turbo manifold for sale pm ill let it go for 130 shipped

[xbxradxsx]

I just got e-mailed back the other day from turbokits.com regarding the kit for the cavi. The guy told me that the problems they found was that the auto couldn't handle the power of the stage 2 system, and that there would have to be some customization in the piping. The piping wouldn't be that big of a deal. The transimission is a different story. Isn't there a post on the power the auto tranny can support somewhere on here? It says that the kit gives 90 to 100 gain in whp. I'm still searching for it, but haven't found it yet.

[Alero2k4]

Contact BlackJack, he can give you info on what you would need to overcome the trans problem...

Edit: I believe this may be the thread you were looking for??? http://invision.aleromod.com/index.php?showtopic=16479&hl=

said it before, I'll say it again. GM's Factory sponsored race cars are the Sunfire with a 600hp ecotec, and the cavalier with the 1000hp ecotec, both using heavily built 4t65e-HD's.

If ya wanna stay 4t45, call Danny's Transmissions in Killeen TX, and I doubt you'll put enough HP out of your ecotec to blow that one.

Also, in order to get around the problem of the oil return line, then "clock" your turbo. Your mount flange is from the turbine housing. Most turbos that are worth a crap can rotate the center section a few degrees (but not far) so your oil lines dont interfere with the tranny cables.

Make sure that the inlet line is as close to top (12 o'clock) as possible so you dont starve the bearings, and ensure that the return line has as straight of a route as possible back to the oil pan, and you should be fine.

Lastly, you may have to put a pressure restriction valve inline from your oil source to the turbo so you dont "overpressure". Common problem alot of people dont think of till it's too late and have to buy a new turbo.

Find anything yet on a 2.2L automatic turbo? Ive been trying to find one for weeks :/ No luck yet.

[Cliff8928]

You can get a turbo Ecotec with an automatic from the factory. It's called the Saab 9^3. All those parts should swap right on providing there's adequate room under the hood, then you'd just need a custom tune.

[Spilner521]

The auto can handle the power. I have a turbo auto...it handles the power. I know, I know...it's not the Ecotec, but the 2.4 uses the exact same 4T40E transmission.

Most people that want a turbo kit aren't going to push stupid amounts of power. If you just want a low boost turbo setup, the auto is fine. The main problem with those kits are the charge pipes. They are routed under the engine where there's plenty of room with a manual tranny. But the auto is much bigger and there isn't much room so you'll have to fab your own piping from the turbo to the intercooler. The intercooler to the throttle body side will be just fine how it comes.

link?

[jturkey69]

starting 2003 any saab 2.0 turbo was an ecotec, however there are 3 versions of the turbo ecotec ranging from 150 hp then 175 which are both low pressure turbos, then 210 for the high pressure model turbos

[Cliff8928]

I'm not sure, but i think a couple of those variants may be discontinued now.. I know the new high-end engine in the saab is a Twin-Turbo 2.8 DOHC 60°V6.

[Spilner521]

Yeah...now they have the 2.0L 210hp version as the low power engine in the 9-3 and a 2.3L 260hp version as the high output engine in the 9-5. That 2.8L is a twin turbo? I just looked it up on the Saab website and It doesn't specify, just says 2.8 turbo V6 with 250hp. Either way, single or twin, I can imagine that engine has a lot of potential. A modded Saab 9-3 that can hand a mildly built Supra or Evo its ass....hmmm...

[jturkey69]

^my thoughts exactly...saab and volvo both have some sleepers

[Cliff8928]

looks like I fudged that one a little, the new saab V6 has a twin-scroll turbocharger..

• A twin-scroll turbocharger with duel-inlet housing. The turbocharger features two impellers that are fed by separate inlet chambers from each of the two exhaust manifolds, spinning a single shaft and compressor that generates up to 9 psi of boost. This design optimizes exhaust pulse energy, delivering immediate throttle response, smoothly generating power and virtually eliminating turbo lag.

It also has 10:1 compression.

But to stay on topic, the turbo parts for use on an ecotec can not come from a 9^5 or any other 2.3 lire saab.

Exactly. To fit anything on the Eco you'd need to use the 2.0 saab Eco engine for the parts.

And on the turbo V6....10:1 compression and a twin scroll turbine = holy throttle response. I'm sure the pistons and rods are already forged, just a question of how much power they can take. Still, I'd drop compression to 8.5 or 9, swap to a little bit larger turbo with a front mount intercooler, P&P the heads, do a full turbo-back 3" or even 3.5" exhaust, and then get everything tuned to around 15-20psi. That would be one fast Saab sleeper that nobody would expect.

Then again...who would expect to get beat by a turbo Alero.....
