Chevy cobalt or Honda Civic?

First and foremost, my names T.J. and I am brand new to the site, but I would like to be active here, so hopefully I'll see a few of you as time goes by. back to the top.

I am 20 years old, and I work two *** jobs (7.25/hr, and 8.00/hr) so I get about $700 a week... keep that in mind.

I am planning on getting a car that will start off as a sleeper of sorts.. I want to get something, pour what excess money I have into the engine for the first year or so, because nothing pisses me off more than someone who slaps flowmasters, decals, and rims on their car... but it can't go over 110... that's gay. The game plan is to slap a cold air intake, switch it over to full synthetic, slap some exhaust on there within the first month of having the vehicle.... save up some cash to drop a supercharger in it then start working on some exterior stuff...

The kicker is I want something that I can still push to about 200k miles

I was wondering (in your personal and professional opinion) should I get a Chevy Cobalt, or a Honda civic?  

Either one is a good choice, bro. It all depends on what is available for them for you to decide on which model to go with. Honda has a really big following wit tons of aftermarket support and I've seen some builds that make one shake their heads in astonishment with the amount of HP that they gained after a build.
The Cobalt is a cool little car from GM and also has great potential for building. I've seen a few builds and have total respect for the people that built them. They were actually really good builds.
If I were you, I would see what is available, the cost of what's available and the estimated HP gain from what's available. If it's power you strive for, your research will give you better answers than not as to which brand to use as a platform for your build.
Advice? I would have a machine shop give the head a valve job, aggressive cams, port match and a good intake and exhaust to achieve better flow and decent HP gains. It won't be much naturally asperated, but if your going to install a turbo down the road, you won't need to do much in the way of internals once you get there. Just make sure that you build to suit before you get the turbo installed.
Also, keep in mind that with more power comes the need for a more frequent maintenance schedule. Synthetic oils help greatly in that, but consider the fact that more power means more strain on parts which means more wear. Again, synthetics help greatlty, but it's not a bullet proof solution for the wear that comes with more power. High quality proven parts, a good machinist and a very good tuner is a more bullet proof way to have a lasting powerfull engine.
