Hello, I'm new to the forum! Nice to met you all. I have a 2010 Mazda 3 S GT 2.5. I've owned this car for a year and a half and it has been a fantastic car. I've recently put on some new coilovers and new wheels and tires as my first mods. I want to make more power for my car and was wondering if anyone have modded their 2.5 with the 2.3 turbo from the speed 3. If anyone knows how much it has cost, what hardware besides the turbo i need to get from the speed 3, and how difficult of a job it is to do so. I know it's probably cheaper to get a Speed 3 rather than upgrading my 2.5, but I would love to hear everyone's opinion on it and if it's all even worth it. Thanks
