how much boost can a stock 2.2 handle.

REIGN SS

word round here is 2.2 internals handle up to 250HP...

its not about HIGH BOOST its about how much power you can get w/ the lowest amount of boost

murph

i am trying to put a turbo on my 2.2 and i was wondering how high of a boost to go with out have to change a lot of stuff. i am putting aftermarkit intake and exhast. and maybe a new header. i dont want to blow the motor so just wondering how high of a boost the car can handle. thanks

AHHH nnonoononono STOP please don't order anything.... if you're going turbo an intake and header is pointless as they will be specific for the turbo and included... and it's not about boost it's about air movement... and lower temps. high boost doesn't mean good numbers...hell there are people using the stock m62 on their ss/sc and pushing like 17-19 PSI and still not breaking 300

it's about engine HP and torque that matters before something pops

murph

well i am trying to get a lot of hp out of my car. i heard a turbo was the way to go so what kind of turbo do u suggest for a stock 2.2

You need to think this out really, really well. What are your power goals? How much are you willing to spend? Do you want to go with a turbo kit, or do a complete custom job? Research is the key, otherwise you will end up wasting alot of money.

Please Please Please

1. Read the Turbo FAQ that I compiled along with Halfcent
2. Do as much research on how a turbo system works before spending any money
3. It's not about air pressure (boost), it's about the amount of air flow being sent per PSI of air pressure. There is no real answer to your question.

We seem to get this type of question on here alot.

NJHK

Tell me about it.

Stock J body 2.2s run about 10psi from the supercharger upgrade kit IIRC.

murph

well i dont care about the money. i want my car to have about 230 hp. what should i do. i do a lot of old model cars. i know how to make them fast i am not a computer wiz. i do not know that much on how these new cars work.

in all honestly i usually hate that people say this but if all you want is a 230HP car... trade it in for a ss/sc. because turboing a 2.2 is extremely difficult due to lack of tuning....the 2.2 is very different from older cars... it's very much so possible but you'll need alot of help if you don't know what you're doing... it's not that 230 is impossible but.. without doing everything correctly you can easily blow you engine..

if you're looking to keep it 2.2 the do an engine build first then you'll have a little bit more leeway

While your at it, you might as well throw a Patriot stage 2 head on.

NJHK

Then why did you buy a 2.2 if money isn't a issue?

XM15

Ouch. Logic FTW

i wonder that too but i didn't wanna be a dick haha thanks for making me look better adam

if he wanted a balt he could've at least gotten a 2.4 so he would've had a better tuning option....

NJHK

LOL

You're welcome

Red06LS

What ever you do what ever tubo stuff you use i shuggest that you also go to crate engine depot and buy the 2.4 manafold its one piece and the 2.2's is two. The 2.4 one ill be able to stand more and is better flowing. Good Luc!

murph

because i wanted to do somthing with my cobalt to out run the ss. i love to tune cars to make them out run the better models. that is the reason behind what i am doing. i want to role up to a ss modle and smoke the hell out of it. them thinking it is a ls model.

NJHK

Okay...

Well I wasn't saying you should have gotten a SS/SC but why didn't you get a better platform vehicle, that's all I was saying.

How much experience do you have with forced induction?

elecblue06

iTrader: (1)

the only problem with that is the 2.2s are ridiculous to tune correctly

murph

none, i am more for engine upgrades than i am with forced induction. i am trying to learn alot about them though. i was more for motor than i was for turbos but it is coming down to where everybody is using them. and it is more hp for the 4 bangers.

oh lord

poppagun

you know if you think you can turbo it i say go for it can i ask wat year you cobalt is.

I remember reading some where in some forum that GM says a 2.2 with stock internals can hold up with 8-10psi with a 50 shot...
