I was wondering if it would be worth it to turbo this car my question in general. Is What would i need besides the turbo kit listed below like pistons stuff like that fuel pump. What I am trying to acheive is around 350hp - 400hp. I would like to be about the same fast as a srt-4 stage 3 non toys car. Would this also be alot of tunning required since i dont have a dyno near.

thanks for the help

idk there is a few guys here with turbod balts that run 350'ish maybe they will drop some advice...

bump

 

clutch

 

from what ive learned, our internals are only good until 300hp. even at that read countless stories of ppl blowing their motors and they all seem to be the same parts. deff invest on some forged pistons, springs and valves. and MOST IMPORTANT i think, is a meth kit. i just read an article on meth kits and considering your going tubro, meth kits work the best. better than an intercooler which sometimes cut down psi.

 

Id imagine they can send you an HP tune, thats what they do with thier other stuff

 

uggg...
you have many many many many many hours of research to do before you can even say "turbo cobalt". not to be mean, but you have hardly any knowledge of this car at this point.

Research man

 

The TAG kit is an excelent start. They provide you with a base tune and the major parts. Internals would be another thing. You should probably start looking for rods and pistons for that power level.

I wouldn't bother with water/meth. Yes it can aid in cooling, but it dispaces air and it needs to be monitored to make sure you don't have a pump failure or you run out of water/meth while boosting otherwise you have no cooling and most likely lots of knock and potentially no motor. Get the proper sized FMIC and you won't have an issue. People think biger is better, but too big will create boost drop and lag.

 

Definitely upgrade your axles. That's the first thing I'm doing before I take the route towards Turbo... But I would also imagine that if you are pushing that much power, you're going to want better suspension and handling or you're going to be all over the road.

Personally, I wouldn't take on a turbo upgrade, especially a large turbo without replacing damn near all of the internals on the Balt. It appears there are just too many limitations of the stock setup. But you are definitely going to want a means of efficiently cooling your setup... so I would go with meth/water personally, but quite a few people seem to be going with Cry02 setups.

 

forged pistons, springs and valves, rods, hahn exhaust, downpipe, clutch, fuel pump, injectores, tag turbo, tag tune

Im just wondering is this really worth it

I like to be diffrent. Im sure no one has this setup around here.
I also looked into tag stg 2 kit but looks like weak sauce to me.
iwant to trap 1/4 in teens

cant forget suspension

How do you know i dont have any knowledge of the car. Because i have few posts it is because maybe I do a thing called read before I post.

 

People are blowing motors for a different reason besides limitation of power...

When you run such a inefficient setup as some of the people with extremely small pullies, you start to look for VERY rich air/fuel mixtures not as a way to make power but as a coolant for the combustion chamber. So they are exceeding duty cycles on even larger injectors to achieve such rich mixtures. Because of this, they are running into fuel system issues with the cyclinder # 4 being deprived.

It's not a power issue.

 

Good luck getting Tag to actually produce it...do some research on their twin screw swap and how they basically have fell off the face of the earth

My suggestion (and what I did) research teh **** out of it, spec ur turbo (for ease of assembly make sure it fits behind the motor first), find a shop that has experience in building custom turbo setups, buy hptuners and learn to tune....Its a long hard road but very rewarding. On 18psi, still untuned, ill take any s/ced cobalt. New alternator arrives friday for my car so i can finally finish tuning and well see where its really at.

 

Your **** is going to be a beast. Good luck Dan.

 

Axles, Clutch, some good wheels, motor mounts, CABs, head gasket and head studs.

Now, as far as others blowing their motors, going turbo will put MUCH less strain on the motor and like NJHK said, will be much much more efficient then the Eaton, which in turn will put much less stress on the motor. Our internals are already forged from the factory, and are fairly strong, but wear and tear from an ineficient setup will take it's toll. I will also have to agree to do ALOT of research, you could get what you want for much cheaper then 5K, and it is always a good idea to know what you're getting involved with ya know?

Sorry, when i wrote good wheels, I meant more along the lines of tires. lol

 

ok thanks for throwing that in. i was wondering why people were saying that "our internals are only good for 300hp" didnt make sense to me when most stock balts are putting down around 230 hp. i mean thats a margin of only 70 hp, no way a manufacturer would build a car so dangerously close to its limitations and then sell performance parts for it like the infamous stage kits that would cause its death. that saves me the thread of having to ask about our internals and helps answer this guys question. also if anyone knows of a intake manifold that would replace the superchager setup you could just buy a universal remote mount turbo kit. people have excelent results with those

 

a turbo kit would be a very wise selection, if you throw on a 2.5 pulley 20 PSI and do a bunch of cooling mods you still wouldnt achieve the power that you can make with 15 PSI on a turbo. In order to make 20 PSI on our cars, the supercharger draws somewhere in the range of 50-60HP from the engine. **** just turbocharging a stock cobalt 2.0 and removing the supercharger, leaving the same PSI would give you a nice 30-40HP increase.

The internals are more than fine to 400HP as long as the engine is tuned and designed right. Dont expect to slap some injectors and tune with a 20 PSI turbo and expect it to stay happy for long.

 

no i read your first post.
i told you i was not trying to be mean. but you are asking for answers that are readily available on the site. that is all.

i am here to help. sorry if you think you know enough then.
