12' Civic SI or 12' Mazda speed 3

I used to have a MS3. Do not buy it if you plan on modding much beyond a catback. The motors have really bad PCV systems, weak journal bearing turbos and they tend to spark knock a lot. The High Pressure Fuel Pumps are known to lose PSI quickly if boost is raised and can run the motor dangerously lean. I knew six people with aftermarket turbo setups on their cars, all professionally installed/tuned and every single one of them blew their motors due to issues with PVC and crankcase pressure and one guy who didnt upgrade the HPFP.

Safe bet if you get one is to keep the mods minimal, do upgrade the HPFP with the CPE one ($1000!) and upgrade the intercooler if you want to avoid spark knock.

If you leave it stock and get a nice extended warranty, its a fun car for sure. The 08-09's are faster though!
