I dunno if it's been talked about or not, but my 15 journey 2.4 is an absolute dog. I understand the caliber srt and the journey share similer "world" engines that replaced the 2.4 EDZ engines in the older stratus/breeze etc etc. Exhaust manifold from caliber looks to be direct swap as far as gaskets linking up with holes. Has anyone successfully done this? I have a way to tune the journey as of now. Would be low low boost. Maybe 4-5lbs.as the compression ratio on it scares me with going higher. Don't want a v6 journey so that isn't an option.
