Hey guys, I think this is my first post so here she is...
Just picked up a 1993 Cavalier 2.2 base model, 2 door and all black WINTER BEATER... On my Jeep cherokee I swapped in Injectors out of a early 90's 5.0 Ford truck... is something like this doable on the cavalier fuel rail?
What kind of vehicle can I get injectors out of, that will be a direct replacement with a higher cfm. Same with the fuel pump... another vehicle I can get a higher flow pump from?
Aside from this, what else can be done... ghetoly... I'm going to rip up something with the intake with a cone filter tonite (put it upside down so it'll draw air from the passenger side instead), I've already removed the resonator and catalytic converter, complete tune-up...
Perhapes, advance the timing? Fuel milage is NOT a concern, just getting a bit more 'pep'
let me know guys.

Stepping away from the car would be the best upgrade.
You don't know sh** about engine.
Bigger injectors doesn't equal more power. Useless to get bigger injectors on a stock motor. Second, CFM is for air, not liquid.
If you think your modification will help, go by the Venom module, the air intake chip and a tornado then come back bragging that you can run 12's or you have 300hp.

Well i used injectors out of a mustang at first the red tops.You can find those in a junk yard in mustangs crown vics ect. Than just cut off the injector clips and its real ez to wire.CHeap too.

BAD INFO
The pre-98 2.2's are all side fed injectors,or in some cases, TBI (I think, but at least they are side fed). You cannot swap them out.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
88-91. The 2.2 came out in 90 but the 2.0OHV is the same engine.

I may not know @!#$ about "these engines" But I DO know my fair share about engines in General. No nay that everybody knows everything about every engine,.. gotta learn, I managed to push 230hp out of a car only designed to push 160 stock... only with simple "bolt ons" Everything from complete engine swaps, suspension swaps, larger dsm injectors, walbro 255 fuel pump, custom stainless 3" turbo back exaust, spearco fmic custom plumbed with shaved head, t-bird turbo at 14.2psi, along with proper tuning and slight modifications to factory parts.,. things can go pretty damn well... I've grown up on turbo vehicles where its "all about fuel"... learning proper tuning to minimize detination hence why I'm asking regarding the $300 cavvy...
As far as I can tell, these engines are VERY basic to work on. No turbo to @!#$ with, nothing to break... room for a larger rad etc etc,,, Now unless you're going to chip in without being a @!#$, than dont bother responding with useless information to a thread that I started.

Big deal...I pushed over 300HP out of a motor designed to hold 140HP. What's your point. Just because you can push a stock motor doesn't make you and expert by any means. Unless you pushed it while testing, like I did, you didn't learn jack @!#$ about the motor or car you did that on.

You obtained a 70hp gain on a turbo motor from bolt ons. I can believe that, but you will NEVER get half that from bolt-ons with our cars (unless you consider a bolt on turbo/ supercharger setup, or if you have a H.O. or w41 quad 4).
I can assure you Gilles knows more than you, and I am sure he is sick of hearing these newbish posts (not to say "you" particularly are a noob though).
Unless you have forced induction or high lift cams/ rockers, built bottom end and P&P head: larger injectors are not necessary on these motors.

"Youth in Asia"...I don't see anything wrong with that.
Yeah ^.^ Needed an exaust so I put a stock one back on, leaving the cat out to keep costs down.
Thanks for the information anyways guys... I'll get a header ordered up and that'll be the extent to 'modifications' aside from the WAI with a cone filter
The way fuel work on any engine is the same. You can have a W41 with hot grind 2 and a 1.0 Geo engine, both run stoich at 14.7 and will not gain more power from going overly rich.
No engine will gain from bigger injectors unless modify.
Also, if you did build those cars with the turbo system you said, you wouldn't ask about injectors cause you would know enough about engine performance. Unless you are pretty dumb.

I kinda run bigger injectors. So I'll explain something to you.
1 - you have (like mentioned) side feed injectors. While pretty much everything else in the world is using top feed injectors. So you're not going to find any sort of junk yard upgrades.
2 - I run an older ECU. Exactly the same as what you have (cept mines for a 6 and yours is for a 4). The injectors are appropriate size for my ENGINE. But the ECU is programmed for a smaller injector. Heres what happens. I start the car, and the a/f gauge goes a good distance into registering RICH on the a/f gauge. Almost buried. Only time it goes back is when I coast in gear and the ECU does fuel cut. But it never goes back to the lean area.
WHY? The ECU is trying to meter fuel based on what it believes is equipped. It knows no differnt. So, if you're going to change the injectors, you better get a new chip, thats custom programmed for those injectors. Or, burn up cats (if you put them on) and shell out the $$$ at the gas pump.
Yeah your right that was horrible info. I misread his and for some reason thought he was talkin about the 2200. Thats a my bad, Sorry!
