How fast do you want to go? You can do all sorts of things, just depends on how much you want to spend.

It'll also help to know what kind of Cobalt you have.

So, manual or auto transmission?

It'll be much easier to achieve 250 whp with a turbo setup, and your transmission should be able to handle it. Manual will need a high performance clutch, but I don't think any major rebuilding would be needed.

The main thing to worry about is building the engine. You don't want to have any valve float or parts exiting the engine. Forged internals, new valves and springs are all a good idea.

I can't say I've seen a complete engine build kit like that for the Cobalt. I think you'll have to stick with piecing it together yourself.

The good news is that you don't need a new crank - stock one is good till at least 600HP
