RallySport Direct’s Twincharged 2015 Subaru WRX

This year we were able to celebrate the 50th anniversary of the SEMA show, now most of us know that SEMA stand for the Specialty Equipment Market Association, but when it was founded it stood for Speed Equipment Manufacturing Association. Although the name has changed, the spirit of Speed Equipment has lived on through all 50 years.

This year it was all about speed for us, and we’re not talking about just the cars. Leading up to SEMA we were in a massive time crunch to get both our FR-S and our Twincharged WRX ready for the show. Not only did we have to be quick to get the cars ready, we also had to make sure they were done perfectly as well to honor the 50th anniversary of SEMA.

This is a car we never intended to be at SEMA, it has seen offroad rally adventures, multiple sessions at the track and normal wear and abuse of a fun daily driver. Needless to say it was not in “SEMA” show condition, so one of the first things we needed to do was remove any and all body panels that were chipped or damaged and we either had them re-painted, or purchased a new part to go back on the car.

Getting the car show ready was one thing, but the big project was getting the Supercharger to actually fit and work on the FA20 from the WRX. I vowed to myself that we would be driving the car in and out of SEMA, no matter what. When we initially started this project, I made sure that the supercharger would even physically fit, but once I confirmed it would with the use of 50mm spacers, it was go time. We had prototype spacers/adapters made that fir between the supercharger and the heads, we had to modify the supercharger flange itself to accept the new bolt pattern for the WRX heads, modify a FR-S alternator bracket, extend wiring harnesses, modify the WRX throttle body, and carefully move/relocate many things in the engine bay to name just a few. In the end we got it to work, and not only does it fit, but it just looks absolutely stunning in the engine bay as well.

Along with the added forced induction, we also went with 19inch Advan wheels wrapped in Yokohoma tires with Brembo OE Gold brakes underneath. The Air Lift Suspension allowed us to dial in the exact show height we wanted, and I must say the car looked stunning with the STI lip kit, it really gave the car the exact appearance we were looking for.
