Hey, I have 2002 LS (2.2, 2200), currently with 37k miles. Im thinking seriously about turboing it sometime within the next year. Ive hear alot of downtalk on the 2200 and what it can handle. My plan is to start with runnin maybe 5-6 psi on stock internals. If i decide to boost more, i will reinforce the engine more, but id like to start with it on stockers. The car is my daily driver, and I understand that aftermarket turboed vehicles are more prone to some minor problems and it provides the potential for more vehicle downtime. If it is down my boyfriend said hed give me his 06 cobalt ss/sc to drive because he is looking forward to my cavalier to be turboed. So i guess my question is if this is a logical thing to do, running it on stock internals, especially seeing that its a daily river... Any input you canb give is much appreciated. Thanks!!

as long as the car is tuned properly, the 2200 loves boost...... Ive been going on 4 years with mine...

CavAttack, are you still on stock internals?

I have heard the samething, on here and on the streets. The one thing that I did hear about is that if your close to 100,000 miles or so, you should rebuild the engine first then put the turbo on it. That is just to be safe that you do not screw up the motor. The more miles on the engine, the less that engine will like the boost.

yea thats understandable... thats why i stated that i have 37k, depending on if i do it next spring, i suppose it might be hitting 47k... i just realized how much that sounds like! haha. but i suppose if i do wait until then, ill have more time to put better parts in.

Hell i am going on 2 years now too. My 2200 loves it. As long as you do it right, you shouldn't have many problems. Just like Cav attack said. A good tune, and your set. I am running 10psi Daily on stock internals.

ken- what size injectors are you using?

beleive it or not, YES... as far as bottom end... I have a mild P&P on the head....I usually have it at 10-12 psi with a Super 60...

I am stock Bottem end. With a Fully P&P head, and all that good stuff.
I am running the S/C injectors. 310cc I love em. no cuting or splicing, but i know i am gonna need bigger when i up the boost again.

Nice, well you guys give me some hope So it sounds like the bottom end will be fine and the way to go would be to go with a mild p&p on the head. How does the head hold up without a p&p? Also, what psi are you guys boosting? And how are the power gains? Im look for some gains, but being a daily driver im not gunna push it too hard. But its an addiction so we'll see where it leads, hehe.

As far as head work goes. You can keep it stock, but I recommend opening that bad boy up alittle. it will help you reach your power goals alot easier. I am running 10psi with p&p head. with the same exhaust you have with a 2 1/2 inch down-pipe. I am right around 220 Whp. I have to get a better tune, and I am sure i can get some more out of her.

get larger injectors a fmu a big frumpin turbo.. and rock the casba..
Boost is all about tunning... more fuel more boost . or vice versa
Boost is adictive, you will always want more... but you just need to do it right.
I have been at 13 psi before... nothing real big broke...
I need to redo my fuel system before i go any higher... but it will be yummie...


horsepower is how hard you hit the wall, Torque is how far you push the wall with you

How are you idling those injectors ?????

I tried idling 2001 z24 injectors and they wee rich as hell and laggy when I pushed on the pedal fast........

so I threw the stock ones back in

I turned my idle Psi down to 35psi. and the car idles like a champ.
I love these bad boys. lol.

I had the Z24 injectors before these and had no problems with those either. hmmmm

i've been running around for like 2 months now boosted, stayed at 4 psi for awhile due to some stupid issues' with the wastegate and dyno'd at 127whp with a crappy tune on 4psi with a crappy .42/.48 turbo and a 3sp auto(literally tuning on the way to the dyno)

i also have my head port and polish, and i think it helped alot out of boost and in.

i am now drving at 8psi daily drivin and it loves it, but still have some stupid issues with the wastegate so it doesn't hit full boost until 4000 rpm which leaves no room for any power on the 2200...

and i am running on ford red top injectors, best bang for your buck when you can find them cheap..they leave you with alot of head room and i can still idle with them pretty easy, because of megasquirt

does the car idle like a champ or is that just a figure of speech and you don't know the AFR........

I had 99 z24 injectors (different wiring harness) in my car .... not 2001........ getting 12.0 AFR at idle...... a lot rich........

I have both sets of plugs for different style injectors on my harness........

so today I'm goiing to try 2001 z24 injectors..... see if they are better.............. they are different style injectors completely..... the body of them and all is completely different......... so the type.... (peak and hold etc.....) might be different.....

thanks for the advice Ken..... me and you always seem to be on the same page....

Thanks Bro

Well theres your problem right there Lee. You NEED to use 00+ Z24 injectors. There good for about 6-7 psi of boost before you start clipping them 100%.

And yes I meant it as My car Idles the 310cc at 14.3-15.2 Af ratio.
Then under boost i can run them as rich as 10.00 Af. If I wanted. lol But they cant handle the 11-12 psi range I am aiming for now. So I am gonna have to upgrade soon.

great ken !!!!

going out now to swap em quick.... be back when I;m done tuning and it's running good....

are you idling those 310's with an AFPR ???????

or SAFC ......... or something else I don't know about hehhe......

hes using the cartech to adjust idle and boost
thats what im doing too thanks ken

well,

there in and the car is idling 14.7 - 15.3 40psi idle pressure......

wouldn't start for a while....... pulled it all back apart found one injector o-ring leaking ..... (I think).... replaced it and it fired right up..... really lean........ then I adjusted the AFPR...... now it's idling perfect .....

one problem..... engine light..................

so I'm back inside waiting for the PCM to reset... (disconnected the battery)

I think the engine light was because I was swapping vac lines while it was running and the idle psi shot up to 60 when I made a vac leak....... so I think thats what it was...............

get this









THE STOCK FPR VAC LINE IS HOOKED UP AND I CAN STILL CHANGE THE IDLE PRESSURE....................THE AFPR has a vac nipple..... I'm not using it ..... just adjusting the screw on the AFPR to change the psi at idle..... it seems to be working ........

or should I take off the vac line from the stocker FPR and put it on the AFPR...... ???

If you have the vacuum line hooked up to the stocker, the stock base pressure will be the lowest you can go. If you don't have that connected, stock WOT pressure will be the lowest you can go.
Either way, the AFPR after the stocker will only let you raise base pressure, not lower it (like a boost controller).
Best setup: GET RID OF THE STOCK FPR lol.



fortune cookie say:
better a delay than a disaster.

Sorry guys, I am pretty new to boost. But im trying to absorb what i can So, if i run like 6 psi, which I think im gunna start with, would 00+z24 injectors be the best way to go? and do those match up with the 2200 w/out any problems? I would say for now im gunna try to stay with a stock head and see how that works out too, before i do the p&p. Im thinkin that i might go out and get another head and do the p&p on that one and then swap that in whenever i get it and have that done. in time though... But I cant wait to hear the BOV... mmmm, sex!!

Oh btw, i have heard that with boosted cars, a p&p in most cases is not the best thing to do becauase it can weaken the cylinder walls...? Atleast thats what my boyfriend found when he was plannin on turboing his honda. Thank god i got him to by the Cobalt SS/SC

I was told if you leave the stock fpr on the car.... leave it without a vac source.... and just use the afpr...... leaving the diaphram open and just letting fuel through to the afpr..... which does the work.......



so if what your saying is true.....

what is the stock idle fuel pressure for the 2200...............

I had my stock injectors running at 40psi idle.......

the z24's that are in are running with the same 40psi idle with a 14.7 - 15.3 afr .... which is perfect......

I can lower it from 40 lower if I would like too.....

so this must mean if what you say is true..... stock idle pressure would be lower then 40psi.... or 35 psi ....... etc...... because I can go that low......... and I shouldn't be able to lower it .... (like a boost controller).......


so what do you think ?

Okay ......

afr is good.........

the car is misfiring..... no flashing engine light........ I tried to reboot the PCM by diconnecting the battery and the engine light remains.................................

the afr is good at idle at 30psi or 40psi...... run almost the same......... same amount of vac.....

anyone ???
