[13dartrallye]

I've just got my hands on a 2013 dart rallye. I would love to beef up this car and put some reasonable performance into it. I'd love to keep the stock internals wth stock valve train, and I'm wondering what hp and psi i could safely put in it. I've never really done anything of this sort to a car, where do I start? What parts could i put on it?

Have you checked out modernperformance.com yet? They have a pretty good section on the 1.4 Dart motor. It would be a good place to start, in my opinion at least.

Good luck!

I just read that, due to design, the 1.4 won't benefit much from external bolt ons because of a huge limiting factor; the cylinder head. Buying a ported head with bigger valves allows boost levels approaching 300HP or so. Without it, like you may have read already, you're looking at a cap of about 225-235.
