I just bought a universal turbo kit for my 99 2.2l cavalier. i was just wondering if anyone has any sugestions of what i could do to make it all work on a stock motor. do i need to run a bigger fuel pump with bigger injectors and if so where can i find some bigger injectors at? How much boost will the stock motor take? If i decided down the road to build the motor what is avaliable for a 2.2l because i have searched the web and it is hard to find aftermarket performance parts for the 2.2l. if anyone has advice on this or has turboed a 2.2l i would apperciate some advice. Thanks Paul nullnullnull

Im no expert, but i know my way around.. im running 8psi on my 2.2 only thing is i have the newer ecotec... i can give you a base though...
Install the turbo kit... make sure everything is ran right you oil line is working and everything is together.. fuel pump really is not needed unless your planning on running a lot of boost, and a lot of power.. its a must to upgrade the injectors tho.. on my 2.2 i have 450s on it running 8 Psi.. its extreamly important to tune your car ASAP... try not to drive it till you do... To be honest you can tune the car yourself... very simp.. Hp tuners is what you will use...I think... buy the credits and the cable... you can really fine tune it, but to get it running good and right the only thing you really have to do is change your injector constant and a few other things... If your really set on throwing this kit on be sure you have everything you need or it could be a mess real quick.. lol....

You NEED injectors, go to a junkyard and get some from a turbo car or alot of people (me) use the injectors from a 80s mustang gt. they are 36lbs and thats plenty. generaly you can put MAX 8psi to a stock motor, and its good to get your car dyno tuned by a professional

where did you get your injectors at?

how big of an exhaust should i run?

mustang injectors are nice, but you can get a set of nice injectors pretty cheap brand new... 2.5 to 3in is what i would go.... Also your gonna pay an arm and a leg for a tune, but like a said there isn't very much needed to get your car running decently well... Get started rip some stuff apart and slap some things on its really the only way you will learn. haha.

where did you buy your injectors at?

I got four 440 precision injectors for 160 bucks shipped brand new... great name and big a*s injectors... i noticed my biggest gains from the injectors swap and tune..

hey whats going on im in the same area im turboing my 22 and i know i need bigger injectors because of the force air that going to hit the throttle body

hey whats going on.. i about just about to fire my 2.2 up after putting a turbo in it and one thing that was a pain was the main cooling bar that runs next to your spark plug wires was in the way of the waste-gate.. idk what king of manifold you have but i had to fab up a whole new setup for that. and also when the turbo is bolted on the thermostat housing is going to need to be cut and re welded. and liek what other said its important to have everything before you start caus eits a pain waiting for parts to come in while your car just sits there half together

go on ebay and get a wastegate relocator and you will need to bend your dipstick tube but you can use the manifold for a 95-97 2.2. and you wont need to cut your t stat

Sounds like you bought a cheap manifold that had no thought process behind it... I did not have to do any of that stuff. Only thing I had to modify was my dipstick tube, which is very common.

yeah the manifold isnt the best out there but it works.. i dont mind the extra fab caus eit looks better now. i still have to bend my dipstick how did you do it.

I cut off the top and bottom sections (to be reused) and made a new center section (same length, just different shape... Should be able to see it this pic...

hey thanks man for the pic. your setup is sick. the reason why i had to cut my t stat is because i have my turbo turned the other way. and my wastegate sits on top of the manifold. but its a cheap manifold. where you find that one?

Thanks for the compliment. As for my mani, we fab'd it up in house.. Do you have pics of your setup? Could you turn the turbo the other way?

if u dont have a welder u can stick a crow bar in the filler end and heat it up and bend it.


DRIVE HARD OR DONT DRIVE AT ALL!!!

You guys who say the 2200 can only handle X lbs of boost, what breaks if you go higher, and under which conditions? Assuming no detonation, what's the safe limit with a highly knock resistant charge (racing fuel/water/meth) ?

I've run into a wall at 5 psi (probably ~150 BHP) on a totally stock engine with 93 octane fuel due to detonation. Sounds about right as effective compression is around 12:1, which many consider to be the limit for 93 octane fuel.

Assuming you can keep knock at bay, you can go higher. I'm now using an air to water intercooler with an integra radiator as a heat exchanger (no tank is necessary). I'm also using water injection at a rate of 5gph. With good charge cooling, water injection and ignition retard, I'm confident the 2200 can handle well above 8 psi. Unfortunately, my fuel pump seems to have taken a dump, so I have to deal with this stupid crap before I can enjoy the newly added hardware.

Unlike most turbo 2200 setups, I've got the compressor on the passenger's side and the turbine on the driver's side. Because of this, I didn't have to modify any coolant lines. Running a CAI is more difficult, but the exhaust work was pretty easy. However, the wastegate actuator couldn't be mounted normally, so I had to make up a linkage.

For fuel, you can go with bigger injectors and/or an FMU. I chose to stick with a stock ECU and injectors, and added a 95lb/hr Delphi injector before the throttle body. The nice thing about EICs is that short of some serious F-up, there are never any off-boost driveability problems.

For an exhaust, I find 2.5" to be plenty. If you plan to run water injection at any point, stay away from glasspack mufflers unless you want to see your car @!#$ hairballs all over the road. Ask me how I know.






2002 Cavalier 2200 5spd

now where do u get your computer and stuff tunned at.

are the mustang injectors exactly the same wire connector so all i would have to do is plug the mustang one into my cavalier

yes i do have a welder. but heating it up seems a lil less work. dose it bend easy once its hot??

and yes i did try to have it turned the other way but how the mani is made the downpipe was to close to the t stat and starter now it clears all that..

yea fairly easy u have to make 2 bends and not to much or it could kink.

hey got a question where do you take coolant from and drain. thanks
