Hey Guys...

I need some help here. I don't know the first thing about these cars so hopefully you dudes can help me out...

I have a good friend that bought a brand new Cobalt SS back in 2006. I drove it around a few times and I am impressed.

I am trying to get him to have some fun with this car. This car is BONE STOCK...he has done zero with this car. So what can we do to get this car to go faster?

Obviously a smaller pulley would do wonders BUT how much power can this motor take? Help me out guys! I gotta convince him to have some fun with this car.

Any info you can give me would be excellent.

Thanks!

motor can hold up real well prolly 300whp.
but he should go with 60lbs injectors, 2.8" pulley, NGK Spark Plugs, injen cai, header-back exhaust, front mount heat exchanger, and tune. would be just a start for a little fun and about 260whp compared to the stock 205whp.
and all would cost him about $1,500

 

Holy ****. 60lb injectors?? That's what I have in my car

So the motor can hold up to around 300. What kind of numbers can that pull?? What can these cars run stock??

Sorry for all the questions guys. That's how you learn though

Can I put a smaller pulley on his blower or is it going to make his PCM go nuts?

 

60s is a very common injectors for ppl to run on the car. and dropping the pulley without tuning is dueable but unsafe.
stock they are like a mid 14 car and with the mods i said along with meth and dr's they have gone 12.75

 

Good deal...now I gotta get him to slowly do this haha...

What are the first few mods you recommend to start off with?

 

ottperformance.com
the stg1 kit comes with 60s, 2.8, ngk plugs, belt, and tune for about 400shipped
then intake

 

There's a guy (paul) that made like 414whp with a stock motor so they're pretty strong. The M62 supercharger is what holds back most people power wise, unless you upgrade to a bigger one or turbo it. Heavily modded M62s are right below or around 300whp but he can do much less mods safer. The mods that drew said are pretty good. I would just recommend to make sure he gets a good tune and it should be pretty reliable.

 

well the tune from ottp stg1 kit is perfect since hes all stock so its gonna be almost right on

 

What kind of results do you guys see from Porting the Eaton?

I know some of the 03/04 Cobra guys send there Eaton M112 to Stiegemeier for porting and the results are extremely impressive.

 

im at 270whp and 235tq with 2.79, 60#s, full exhst, intake, frontmount, and tune. i should be over 300whp when the head is done and retuned.

 

ported s/c may add like 5whp but it helps with the effiecency. i have it but didnt notice it that much.

 

Damn cost vs results doesn't seem to appealing with that.

 

mine makes 322 whp and 270 whtq with just bolt ons.

 

I'd say have him get a intake and once he heres the whine so loud..he will want more haha

 

I'v drove around for about 10 months now making over 300whp with no problem

 

dont bs the guy like that lol he is new. he sure does not know that u have a larger tb. a tvs. meth prolly by now front heat exchanger and what not lol dont throw him off like that bro

 

I'd say:

Intake
Longtube Header
Highflo Cat/downpipe
3” exhaust
60lb injectors
2.8” pulley
Colder Plugs
Cooling Mods (front mount heat exchanger, Dual Pass Endplate, Meth injection)
And a good dynotune to wrap it all up.

Probably good for 280whp (depending on the tune). Am I missing anything? Like stated before the OTTP Stage I kit is awesome. You just have to get the I/H/E part...

 

yeah im on my 20th bottle of nitrous. all the mods these guys are suggesting are great. top it with a 50 shot and proper tuning

 

i only have bolt ons . Never been in the moter. I do have a smaller pulley and meth on the way .then another tune , shooting for 350 whp.

 

good work scott. dont tell zuma

 

yea but if u say that if he is new he is gonna thing its all on the stock supercharger which ur not on lol now u get what i mean? not trying to argue or anything just saying

 

i got you man. but still just bolt ons . stock moter.

 

That is VERY VERY VERY misleading..

 

Not only that, isnt that adding your fabled 11% dyno jet would read but I dyno on a mustang? Unless you dyno on a dyno jet or any dyno for that matter that gives you those numbers, post the real stuff. If you have since done that since the last time than I apologize for my error.

 

Pretty much the standard go to mod's with these cars are 2.8 in pully 60# injectors and a tune. You can get a kit like the OTTP stage one which has everything including the tune included. But, as you know a custom tune will be better.

Also a nice cheap mod is the "airbox mod" It consists of takeing of the stock filter and the bottom of the airbox and replacing it with a cone filter. You need to replace it with a filter that has a hose clamp to hold it on because the bottom of the airbox holds the stock filter in.

So for about 500$ you can see a gain of 30-45 hp with a setup like that.
