Mazdaspeed 3? Out of who voted, who has owned one? I have and I regret ever stepping foot in a Mazda dealer. I bought that car new and threw on a cat back and an intake, 20k miles later it threw a rod through the block getting on the highway while shifting from 2nd to 3rd at 3500. Mazda would not warranty because of the "mods". Those cars were throwing rods in totally stock form the same time as mine.
Yes, I'm a little bitter lol
It wasn't that great of a car anyways, still a shitbox. If I'm gonna drive a shit box it will be an SRT-4, cheap as hell to make fast and comfortable enough for me.
Zoom zoom boom cases have dropped to nothing other than for the guys pushing the envelope now. Inital cases were due to tuning too much torque on the low end+ fast spooling k04 bending rods. Detonation is because of DI engine and people threw mods on the car without changing the Fuel pump.
Stock block has been proven to take 400-500whp no problem. Issue came from people being niave about DI engines.
