ok i have a 2005 2.2 cobalt 5 speed. i have the Injen CAI, Pace Setter header(with header wrap), custom down pipe, dual exhaust, TWM short shifter and Eibach sport lines. I am having a Exedy clutch put in next month also. I have some extra money i would like to spend on performance but i dont know what else is out there and what to get. can any of you help me?

any input would be nice.

Thanks, Ryan

 

lol, i dont think there is anything else for performance.. sput the money aside and wait for the turbo...

 

yeah i actually dont want to turbo it, i dont think it is worth it, we have high compression. i dont think it is logical

 

Nitrous, Ported Throttle Body, Port and Polish Head

 

Nitrous... i dont know much about it, what kit, what shot, who to instal. prices???

Port polish head... how much?

Ported throttle body... i dont see the porpose, we dont get enough fuel, the air flow should be fine for now right?

 

Zex Wet kit for nitrous, if you get an MSD window switch and a bottle heater, and have it installed correctly it will be very reliable and difficult to damage the engine. If you are paranoid, go for a 35 shot, if you've got ***** like me, go straight for the 75

Never go higher than 75 until you get some internal work

 

take the header wrap off, you're gonna turn your header to **** in no time if you don't..... it's more "logical" to turbo it then put header wrap on your header and put a duel exhaust on your I4

 

theres a bunch of other stuff for performance...well not too much but yeah.

sway bars...strut bars, engine damper, motor mounts, theres some cams somewhere.

 

No matter what, if you want to go turbo/supercharger or even run higher nitrous get forged rods and pistons. Rods run bout 300-500 and pistons vary depending who you go with.

Those are my two mods I say you do.

 

nitrous, turbo, and supercharger can be safely run on stock internals....to a point. its all about the tuning!

 

To a very low point, do internals, you'll never look back

 

The question you should ask yourself is what are you aiming for?

To me, it sounds like you do what most people do, which is understandable to a degree, is buying parts to see what you can get instead of buying to reach a goal.

When you make a goal as far as what you want, you'd have a better idea of what to research on. If you want 200 HP, read up on what does what, whos reach what with what modification and the list goes on.

So asking us "what can you buy for performance?", no one can realistically answer this question unless you tell us what you want out of your car. I mean, I could list every single part available for an ECOTEC but that wouldn't help you out at all.

So stop, think about what you want and then tell us and I'm sure we'd be happy to help you.

 

true... if you do it right you can go as far as you want or can afford

if you're aiming for that golden 300hp # that every one is looking for then you need forged pistons, new valves, valve guides, valvesprings, and stronger gaskets everywhere.... and probly some other stuff that i dont know about

 

Which there is none available for the "average" tuner.

 

Not necessarily. Every part has it's limitation as far stress...it's just moderation. How much are they trying to push is the question. You don't need to change you bottom end if you're running a small amount of boost pressure or a low shot of nitrous. It's insurance of course but not necessary.

And like said before, there is no tuning capabilities as of yet.

 

Compression means little if you're tuning correctly. Yes, higher compression has a higher chance in knocking but you can still detonate a vehicle with 8.9:1 compression. It's how you're tuning the vehicle.

 

unless i missed it, you should get a high flow cat...and if yu already hav one of those, go cams

 

how is your turbo logical? i would have to buy the kit(over $2,000) then change out my internals which would cost a **** load of money!

and how is the wrap gonna turn my header to ****!? and actually if you new **** about cars and headers you would know that a header gets much hotter then a manifold, it actually turns orange, and the wrap keeps the temps down under the hood *******! and i made my car a dual for looks not power!

 

ok as for the cams, i would love to get some but how can i get it tuned? i would really like a set of the 2nd best compcams!

and to NJHK i am looking to get my car to be faster then an SS cobalt. i would love to be able to beat one at the drag strip, i have before but they were shitty drivers, i want to actual straight up beat an SS. so probably about 220ish HP. that is my goal. once i get there i am going to keep it all on the cosmetics of the car! not that i havnt done that already too!

 

id say port it, or get engine internals, maybe turbo when its out?

 

Header wrap traps heat in the exhaust. If you have the painted header then it will eat the paint and the wrap dosent protect the header from the elements. He actually did know what he was talking about when it came to that.

And if your headers turning orange I would love to see pics of that, it only happens when the engine is at high rpms for a long sustained time. The wrap dosent disepate the heat it traps it in the metal.

 

i just want to run close to what an SS cobalt runs..just so no one can make fun of me for having ss body parts:P

 

If you're talking about doing this naturally aspirated, I think you're going to have to go beyond valvetrain modifications...yup, bottom end work. I don't know if you're ready for all that. It's going to be more of a challenge. Not saying impossible but don't know if you realistically will be happy with the money spent vs. driveability vs. gains.

 

The reason they say that about header wraps is cause moisture builds up underneath the wrap, causing the header to deteriate.

This is why coating, no matter what type of setup you have, is the best option to go with.

 

Well buddy, the next time you go cursing at somone for saveing you hundreds of $$$, you should make sure that YOU know what you're talking about.... in one year, your header is gonna be non-existant and you're gonna have to do something about it.

2nd... if you wanna make 220whp+ you're gonna have to change out your stock internals anyway because your engine is nowhere near as strong as the LSJ..... (so get your head out of the clouds)

and you single handedly deffeted your argument of "Logic" when you said you were doing things for "looks not power"

also... i would LOVE to see your header glow red

and thanks, NJHK and RallyYellow06

P.S. - You don't have to curse and be immature to get your point across
