you betcha

 

N/A is the way to go. Then boost the ***** out of the car.

 

hahahaha

 

Thats what i wa going to do but i said no i'd rather have an SS/SC. Plus then I'd be able to use HPTuners, and all the other cool stuff it comes with. I'm packing the cams and intake mani in a box then going to weight them for ya.

 

You could built it low compression and run n20 for a good alternative until you go FI, but NA builds generally turn out to be dangerous FI builds because of the high compression.

 

thicker head gasket

 

SWEEEEEEET

i have thought about that....if i do build the **** outa the engine like i want, i then have the capabiity of running n2o if i want....maybe lol,,,dont know if i want to though after spending that much money on the build...

 

If you spend that much money on this build, I'm going to slap you in general. You could sell your car, take what you were going to spend and buy a used gto or even pick up a foxbody mustang for twice the power NA.

Don't mean to bash on your plan, but man it's hard and expensive trying to build a fast NA 4 cylinder.

 

meh, someday im sure ill buy a gto or something...but i love my cobalt, dont have the credit to buy a different car and dont want to buy power...i want to build it

 

At what point are the stock 2.2 ijectors no good? With a tb and intake mani from a 2.4 and stage 2 cams do you need them, or you just doing them for the high compression build?

 

both, i figure since the s/c is rated at 205 whp and i hope to be pushing 180+ that it couldnt hurt to put them on now and have them for when i get to a higher hp in my build

 

You will need bigger injectors for your build so try to find ss/sc injectors. when i had the cams and full bolt on i was fine.

 

Ok cause i am planing on 2.4 tb, intake, st2 cams, and tune by next fall this is the first i heard about injectors and was just wondering if the stock ones will be enough.

 

hey tom have you considered rasing the compression ratio to make use of your choosen cam? i started researching the NA build and found that you can indeed build a 200+hp NA build but it's gonna require raising the cr and running high octane fuel possibly even race gas depending on your power goals. keep in mind raising the cr is gonna involve buying more then just pistons and rods and if you want to make safe power at those compression levels you may want to bore the block out to a 2.5l.

just my shitty 2cent

 

what is our factory compression 10 to 1? or say what if we used factory thickness gasket and milled out head down what would that net us

 

yea get high compression pistons like 10.5:1, and port and polish the head and build the motor you should reach more than 200hp

You will be fine with your stock injectors

 

1 was looking at 11:1 or even 12:1 for 250hp plus a 100 shot on race fuel. the redline would have been set at 8k and i was gonna build for the track but still run as a "dd". too much tuning downtime for my taste. it would be impressive to build a high horse power L61 NA but it's not in the cards for me. for now i'm thinking of dropping the zzp turbo kit without the intercooler and using my buddys stock evo 9 mr fmic and welding up some custom piping for it.

 

that is the plan
im going to get it bored, shave the head down, new pistons and rods, and a thinner head gasket...
dont know the exact details yet...but thats a little ways down the road

well i will do it for all of us then

ive got some ss/sc injectors and a harness setup already, just have to get my taxes so i can pay you and for the injectors and ill be in business

 

i like the way you think. i wish the absolute best of luck. if you believe in that sorta thing.

 

Thanks

so pretty soon the debate will be over...i should be getting the taxes in the next two days, ill buy the cams, mani, tb, and injectors and after it all gets here get it installed and dyno tuned by vince...then i can say for sure what im putting to the ground with it
next step after that is upgraded brakes and sway bars....then finish up with some appearance stuff

after that...its time to find a donor motor to strip down and start building

 

what is our factory compression 10 to 1? or say what if we used factory thickness gasket and milled out head down what would that net us

 

Yeah but the stock is 10 to 1. I'd set the redline up to 8k after a valve train job and neutral balance shafts.

 

i'd die to hear a built 2.2 winding out to 8k and yeah the neutral shafts are a must for extreme redlines like that.

 

Well there will be a fully built, cammed 2.2L cobalt once he decides to put the motor back together. haha but the cams stop producing power at 7.5k so i don't see the point reving past that.

The key parts to rev that high is strong valvesprings, and the balance shafts

 

but if you're on spray you can still make power to 8k. that was my intent but it's only a pipe dream.
