Re: Stratus 2.4 turbo is it possible
Welcome to TurboDodge.com. I've turbo'd a N/A 2.4, and a N/A 2.0.. The stock rods are good for about 250hp/250ft lbs torque. You might make it to 300, but you're living on borrowed time at that point. That said.. Things you'll need.. You'll need an AEM FIC piggyback, or a MegaSquirt. I recommend MegaSquirt because it's just all around better, has more features and is more user friendly. It's cheaper too.
The SRT4 turbo won't clear the firewall on a Stratus, so you'll need to pick up a manifold on eBay and use a normal turbocharger. Try not to go for some crazy large turbocharger, as your power goals will be pretty modest with a stock 2.4. There are 3 different (cast log) manifolds up on eBay.. One points the turbo straight up, one points it straight backwards, and one points it down at an angle. I imagine you'll need the down at an angle manifold. I'd avoid the stainless steel headers, you're not building a 10 second dragster, they don't have the greatest longevity for a daily driver.
I notice you mentioned 2nd gen Stratus. Be careful in your selection, some of them (the 2 door I believe) come with a horrible mitsubishi 2.4L motor. Nothin like smokin a ricer only to have that ricer point out your motor is pure rice. While some of the Strata come with the same 2.4L that was in the SRT4 Neon (right up and past the time that the SRT4 was discontinued), minus the reinforced SRT4 components.
You'll also need larger injectors, I'd guess about 750cc would do the trick. You can get the MegaSquirt, and the injectors at DIYAutotune.com. The manifolds are on eBay. I'd recommend running E85 to get around the fact that your N/A 2.4 has really high compression. E85 is 105 octane, so it's perfectly happy running 14+ lbs of boost on a 9.6:1 compression motor. You'll also need a wideband oxygen sensor to be able to tune your fuel curves. I recommend the Innovate LC1, they're cheap, and have just the right features for your needs.
