When we first got the car I always felt like it lacked the punch the older WRX’s had. There is something that is almost too smooth about this new FA20 engine, and not that it is a bad thing, but I wanted that rawness back that the old WRX’s had. This was the start of a journey to not only get that back, but to also improve everything about this WRX.

You would think we would address power first, but nope, we jumped straight into Suspension, well after a catback exhaust 😉


The Racecomp Tarmac Coilovers really helped the handling while retaining a great deal of comfort. We also wanted to make sure we had some proper wheels and rubber on the ground, so we went with some Wedsport wheels with Michellin Pilot Super Sport tires.


As you can see, we also installed some rally armor mud flaps at the same time. I mean we had to! It’s a Subaru for crying out loud!


We also wanted something a bit different on the front of the car. Grillcraft had sent us a grill to try out and we decided to run some yellow fog light covers and tinted headlight film just for good measure too.


So now it was time to get back to the main goal of more power and rawness. I thought a downpipe would be a perfect addition and really wake this Subaru up.


So did it work? Not really. It made a ton more power and really felt faster, but it was still so smooth. Too smooth. So what now? Well we had a new Grimmspeed pulley sitting on my desk, and we have always had good results with crank pulleys, so lets give it a shot!


So did that work? Again, not really. It made a nice difference and is something I would highly recommend, but it did not bring back the rawness. Waiting for the magic bullet, we decided to install something just for fun and some noise. The Turbosmart Blow off valve.. pshhh psshhh


Next up on the list, we wanted a bit more sharpness from the car and less body roll. Eibach had released their Swaybar set, and we decided to go ahead and install them and what a difference it made!


Wanting to get back to my power goal, we decided to go for broke and install a process west intercooler along with a Mishimoto intake.


Did it work? YES! finally. The intake made a massive difference in the punch the car had, it just felt like the turbo came on so much stronger and it just had a viciousness that I longed for and it was perfect. The Process West Intercooler also made sure we kept our charge temps nice and cool to help keep the engine reliable and safe. Now that I had my power, we could move onto some other small and fun things like the OEM Vortex generator.


We had also started using this car more and more for daily use and fun, so we wanted to make sure we could take it anywhere and bring anything with us. Yakima had just released their new rack for the car and we had to have it.


We have also installed Sparco Pro2000 seats as the stock seats were just leaving a lot to be desired, and nedless to say we love them!



We have much more planned for this car so make sure to stay tuned for updates!
