So I've had my cobalt for about a year now and I've done a few mods (gms2, injen intake, zzp pcm) and I'm kinda worried abt running my car hard. Also dosent have as much power as I assumed it would. I want to do more mods but was wondering what stock internals are good till. And if my 7200 redline is too high? Any info is appreciated. Thanks.

 

i got mine set at 7000 and its holdin up i think 7200 is the max for stock internals but i dont know for sure maybe someone can back me up on this

 

stock internals are fine for what you have. IMHO, you paid too much for that gm stage 2. ZZP's or even OTTP's stage kit would have been better. Put it this way: people slap turbos on the lsj and are pushing these engines close to 400 hp without replacing internals (although sleeves are usually fatigued around that time).

 

Highlighted a problem, get a custom tune and you'll feel a difference. Also, you can drop down to a 2.9 if you have 42's (Assuming since you have GM Stage 2).

7200 is to high if you dont have aftermarket springs, id turn it down a bit.

it sounds like you have plenty of air coming in, but not enough exhaust getting out, id at least get a header or downpipe and you would see an improvement

 

I blew my built head off at 8k because I was in a 2.6 and my icpump. Went outlol. If u don't have enough power check ure ic pump

 

I honestly wouldn't run 42's on anything smaller than the gm stage 2 pulley. After seeing my buddy's idc's with a 2.9 and 42's, I'd say just get 60's. Besides, tuning for 60's than 42's gives you more leeway as far how much fuel you can flow.

 

ya my ic pump is out i tried the stu hammer mod lol (hitting it with a hammer) still nothing tho iat2 play a big roll in making power

 

Going from a working ic pump to a non icpump u feel the difference a lot. becuz the timing pull

 

bullshit stock internals will take alot more then 7200 springs included

 

this. when mine was at 7.2 had no problems reving it out all the way. just pointless on an m62 is why it's back at 7

 

Haha. I would love to have a custom tune but I can't find n e 1 in ga who has HPT or trifecta that dosent charge an arm and a leg for a tune. I mean $500 is descent. But I can't find one for less than $900. And that's too high for me. Lol. What kind of header downpipe would y'all go with?

 

Should be around 300. Do a search for tuners in your area there is a thread on who tunes.

 

its really that much of a difference? idk if mine has worked since i got the car

 

for how long? all you dummies keep blowing your **** up

 

this ^^ i wouldnt run mine at that but to each his own man

 

why would ott offer it on their kit as an option if they thought it would mess something up and come back and burn their reputation? just food for thought.
but there are plenty of people who have done it, with no problems

 

you seem to regularly have problems with everything i say.

have an example. you can run 350+ hp and run stock axles at the track and make 40-50 passes and wonder why your axles broke.

you can make 400 pulls on your motor and wonder why your valves bent...

 

the only dummis blowing there **** up are the ones with **** tunes
the tune has more of an effect on the engine then rpm the stock internals will more then handle above 7200

when your ***** drop youll start going fast

 

if you take it that way that's your problem but saying they won't handle it and calling people dummies who do it is just ignorant just cause you got no *****

 

the one big thing about going fast and holds people back is they are afraid to break it. you can break it at 6000 just as quick as you can 8000

 

you sir are a dummy. i never once said it couldnt handle it, i said its not suggested. I like to keep my motor running thanks ass hat.

 

Calm down kids he needs advice not 2 Lil school girls bickering at each other. I got zzp stage 3 kit with midlength setup and it made a good difference IMO. My car rev limit it 7500 but never try to use them all just stay around 6500 or 6000 to be safe. Unless ur going for real hp then don't worry about internals you still gotta get traction or all that hp is going to waste and a good tune helps.

 

mines been running fine through 66k miles of abuse

 

Woww. I didn't mean to cause an argument. I don't rlly hit the rev limiter all that much. I was rlly just wondering wat I can do to make decent power out of this motor. And if anyone know how I can find a reputable tuner near ga. And thanks for all the help so far. It's much appreciated. Lol.
