Stage 4 turbo kit

[Dr.Mambo666]

I have a 99 2.2l cavy and it is all stock(for now).I was wondering if it is safe to put a stage 4 turbo kit on it(16psi with a 150-160 hp gain) and if not what should I put on my car before this?

[i3o2Matt]

heh...not on a stock engine...at all.

No.

Buy a new car.

wow, there is a huge list you need to do for a stage 4. may as well just put up a huge shot of nitrous. Redline and let it shoot. But forstarters... please buy an intake and nice ~3"exhaust with a turbo manifold an not to mention internals and pulies would be nice

I'm assuming your miles are kinda high, you probly wouldn't even want to put a stg2 on there, maybe not even a stg1

The car has 56,000 on it and i can't get a new car the money for the parts is credit for a web-site so i have $10,000 to beef up my car.

wtf is this Gran Tourismo?? Staged turbo kits from where?? What does the setup consist of?? There are a lot of factors that determine the amount of power that can be made on a particular setup. Also, to one of the earlier posts that suggested an intake....if that's an intake like a CAI, that's a waste, but if its an intake manifold, that's more practical. Either way you're going to need a lot to make your car handle 150+whp gain.

I'm not very familiar with Cavaliers or GM in general other than Camaros and other F-bodies, but i would assume that the internals are not capable of handling that kind of power increase so you're going to need a set of forged internals. On my GSR, i'm using CP 9.2:1 pistons and Eagle H-beam connecting rods. That would be a good setup for most any 4cyl build under 500whp.

Another thing you're going to need is a clutch. Your stock clutch (assuming its a manual) is not going to handle the power increase. I would suggest an ACT 6puck clutch, heavy duty pressure plate and a new lightweight flywheel. I went with a 3pk Exedy and an 11lb ACT fly on my car. Since it has larger pads (pucks) it has less chatter upon engagement.

Fuel is another big concern. On Honda setups, you can get by on the stock fuel lines, FPR, and fuel rail until you push into the 500whp range. You're going to need a new fuel pump. My choice would be a Walbro in-tank pump. That will be sufficient for your needs. You're also going to need larger fuel injectors to accomodate the turbo setup. The general rule when selecting fuel injectors is that 5cc will support 1hp at stock fuel pressure. That means that 550cc injectors will support 110whp each which totals 440hp. Another thing to keep in mind is that you DO NOT WANT to max the injector duty cycle so pick injectors that are slightly larger than you need. Now that you have larger injectors and a higher volume pump, you are going to need something to control fuel.

I am unsure of what EMS tuning systems are available for Chevrolet products, but there has to be something similar to Crome for Honda products. They are simple adjustable fuel/ignition maps for the engine. I would stay away from fuel management options like the boost dependent FMU because they are not precise enough to control the fuel demands of a setup like this. FMU's are a cheap and unreliable way of controlling fuel. You would be wise to invest in professional tuning on a good software. Tuning is key to a good setup and prepare to spend a good amount of money on it. For the tuning side of my personal setup, i have spent nearly $1k on it alone!!

As for the rest of the setup, the only thing in the entire turbo setup that you would buy, that is specifically for your Cavalier is the manifold. Other than that, the other parts are all universal. There is no specific turbo, blow off valve, wastegate, piping, intercooler, etc for your car. Therefore, there is no need to buy an entire "kit." Personally i would research what is needed for a turbo kit and piece it together for yourself. That way, not only do you save money and get the perfect setup for your individual needs, you learn about it along the way.

If you have any questions regarding turbo setups, parts, or anything, just let me know....i know i haven't been the nicest guy on the Cavvy forums before, but i'm startin over....later guys

I may forgive but I certainly do not forget...

[Schister66]

thats fine, but i was also getting tired of countless personal attacks after i had posting things. If you disagree with what i have to say, then say it...there is no need to piss others off. We all want to talk about cars and make them our own, we may disagree on how to go about doing so, but we're all car addicts....we should get along based on that alone...

[Lances133]

Fair enough, couldn't agree more, now just practice what you preach and we're all good.

[Schister66]

well we're settled now...i just want to get back to helping people make their cars faster without being misinformed or ripped off....lol

[Dr.Mambo666]

Well first off thanks everybody for your help (leaving out the slight "dispute") The actual turbo kit I looked at is made to fit.Here is the site-> http://www.maximumboost.net/product_...14cb3074d98ec2

Soory haven't figured out how to attach webs to words but that is the turbo kit. The reason for wanting so much power is like everyone the more the better, but also for drag races. I have $10 grand to spend(I'm not loaded but I did get sponsored by Street Car Performance ). Now my second question would be is , would this help any

http://www.jbodyperformance.com/new/...catName=JP0619

And what exactly does that come with(sorry I,m not so great at the whole mechanics thing just a glorified parts changer...Me like directions)
The downside is my car is automatic so the last question of the day is, would there be anything i can do to it(Like a performace shifter thing or what I dont know) It would be greatly appretiated if I could get some help thanks alotopcorn:

A T3 on a "stage 4" kit.....thats pretty weak if you ask me. You can tell that the setup is all hype when you notice that you're getting an SAFC and RC320cc injectors.....plan to not make any more than about 240whp on that.....here is a real "stage 4" kit.... http://www.full-race.com/catalog/pro...roducts_id=820

and as for the head work.....you're not going to make enough power on that turbo kit to justify doing headwork....find a better setup or dont waste your money. Also, the "kit" is horribly overpriced for what is included....

lol that's a dream come true for a cavalier

thats not really a high power number....for instance, i'm still running stock internals on my GSR...im hoping for 330-340whp on my new setup...
