Monster 3 – Turbocharged Mazda 3

Today we feature Johns heavily modified turbocharged 2006 Mazda 3. Monster J is what he’s commonly known as on the Mazda forums, his car started off as a daily driver that could haul his biking gear. John wasn’t even into modding when he bought the car but of course that would all change. He joined and signed up on the forum. He started to look at other owners rides and saw how much other owners were modifying their cars. John got more and more interested in car modification and another gearhead was born. Back in 2006, the Mazdaspeed 3 wasn’t available yet and John started off with simple modifications. Turbo wasn’t even in the horizon at this point…

Something simple like cat-back exhaust, intake and short shifter was the first to appear. I was also lucky enough to have my father in-law (who is a licensed mechanic) to teach me how to DYI everything from the get-go. Shortly after rims and a suspension drop was on the way. However the real turning point to make me want to go turbo was when I test drove on of our BCMazda3 member’s Mazdaspeed 3. I was so impressed with how 260hp feels like I said to myself “I gotta get that feeling into this car!” So a turbo kit was ordered! 

So why didn’t John just get a Mazdaspeed 3 instead? He thought about trading the car in for a Speed 3 but getting a custom turbocharged regular 3 felt more special then getting a stock pre-turboed car to John. Cobb tuning wasn’t available back then which made it extremely hard to tune the Speed 3 due to its direct injection engine at the time.

Turbocharging the car didn’t come without its own issues and problems

The biggest problem, again, lies in tuning. Everything on the hardware side was fairly straight forward. However getting the car tuned properly and make it a daily driver was challenging. What I found out is that getting the car tuned on dyno for power output is entirely different than street tuning the car to make it drive smoothly and idle properly everyday, in every type of weather. 

John enjoyed daily driving the car after turbocharging although he wished his clutch wasn’t so !#@% heavy. So what future plans does John have for his monster hatchback?

Another engine rebuild is in order, plus the ECU upgrade. I am currently using the old Haltech F10X and that limits me at only 15psi of boost. The plan is to upgrade to Haltech S1000 and get the boost up to 25psi. Also I really want to put more time into building the upper portion of the engine (head works and cams). I am already running forged bottom end so that should hold well over 25psi (or so I hope :D)
