I was wondering what size injectors i should go for...i really don't know alot about this sort of stuff...i am wanting just a little more go...nothing major...already got intake and full exhaust...so i was thinking injectors, fuel rail and would i need a better fuel pump to go with a setup like this...i dunno what size injectors my stock ones are...someone help...and also a good place to pick this stuff up...thanks

What he said.
You might want to invest in an actual Fuel management system like a Greddy E-manage, Apexi SAFC or something of that nature for fuel tuning if you feel the need to try and fine tune how much fuel you're actually getting.
Remember, bigger injectors/fuel rail don't mean more power, you would be basically trying to supply more fuel that is not needed.

Even if you have every bolt on for your motor, you are still only using about 65% efficiency of your factory injectors. I wouldn't worry about it bud. Once you have every bolt on for the 2.2 (see my registry for the list because i've got them all lol) then maybe you could dyno tune with an SAFC and gain maybe 5 hp. But... is $240 worh it to you for 5 hp?

Some gains yes but it's not worth doing all that work and leaving your stock valvetrain...you should upgrade it as well while you have the head off.

I forgot to add, you can't swap larger injectors on to your car. Not unless you convert the fuel rail for top feed injectors or run an EIC system, which you won't need without forced induction anyways. My advice? Do a PnP, a cam from JBP if you feel like rebuilding the motor, Comp Cams 1.6 roller rockers (do a search and you'll find all the info you want on roller rockers)

Nice pointing that out...didn't realize he had the 2.2 OHV before.
