When it comes to building a car or working on any project, good results take time. Erick Davis of Tampa, FL claims that he just really likes his car and decided to take his time modding it since the day he bought it back in 2002. That’s right, for over eight years Davis has been tweaking his beloved Subaru WRX and wrenching away performing almost every mod possible. He even went as far to list out the OEM maintenance, TSBs and all the free mods he could find on NASIOC. Everything has been addressed and the results speak for themselves.

Davis also lists many of the mods and custom items on his car as the “DJerickd” brand. The name comes from his username on Internet forums, and was used for things he made himself. There are almost too many items to list, but we included the highlights in the spec sheet to give him props for making all that happen himself. Then again, he has had the car for almost a decade, so time was not a factor.

For Davis, he wanted his hard work to attract sponsors and his efforts paid off. His list of sponsors includes Aquamist UK, Carbon Mods UK, Torque Solution, Kartboy, GrimmSpeed, and SGMotorsports but one of his biggest supporters has always been Prosport Inc. Prosport Gauges has done well for themselves in a crowded market of performance gauges.

Only a few years ago there wasn’t much to choose from and it was all expensive. Prosport’s competitive pricing and Swiss-made stepper motors in their Premium line definitely satisfies customers. The Florida-based company partnered with Davis because they knew he would get the results by being active at events and with local clubs. So Prosport hooked him up with blue Digital series: Boost, EGT and O2 on the dash all in 52mm sizing.

These gauges feature large digital display to keep an eye on the motor functions. The Prosport gauges feature updated sending units for unparalleled accuracy on the vital signs under the hood. Davis also used Prosport fiberglass header wrap to help insulate certain areas under the hood.

Speaking of under the hood, Davis has made some decent progress on his boxer. The turbo has been upgraded to an IHI VF39 Turbo regulated by a TurboSmart 38mm wastegate. The exhaust dumps into Synic Equal Length Header and a Slow Boy modded Invidia stainless up-pipe and down into an M2 3-inch turbo-back. Air is hauled in with a K&N Typhoon intake which has some custom gold foil touches courtesy of Davis himself.

From there the attention was focused on installing a prototype Aquamist HFS-5 water/methanol injection kit and tuning it for maximum gains. The engine was then open-source tuned by Jeff “Snowman” Snow and now puts down around 325whp. The extra ponies were going to be hard on the running gear, so the flaky stock clutch was pulled in favor of an Exedy clutch and lightweight flywheel along with a Driveshaft Shop aluminum replacement shaft. The upgrades ensure that Davis can punch the car and put power to the ground on demand without snapping anything.

The suspension and chassis received the most attention. Nearly every component is upgraded and Davis had to scour the world to find it all. Items from: COBB Tuning, Whiteline, Cusco, Kartboy, Megan and even JDM STi components have all been fitted to the WRX, representing many different countries! With the right coilovers and the right suspension arms, the handling is very capable and is only ramped up by the many chassis braces that Davis runs. The athletics are due in part of the Dunlop DZ101 215/35R19 tires wrapped around burning black Work Meister S1 19x9-inch +20 wheels finished off with Prosport’s very sweet Carbon Fiber valve stem caps. Running JDM 4-pot calipers, the braking gets a shot in the arm with Powerslot Plus 13.4-inch big front rotors, Legacy H6 rear rotors and EBC Red Stuff pads.

The exterior is understated in typical Subie fashion. Everything is clean and shaved just the way we like ‘em (Subarus, I mean). The car was shaved of corner lights, badges, and locks and fitted with a custom rear window spoiler and EGR sideskirts. Then a bunch of JDM STi goodies were added including front lip, rear diffuser, rear lip spoiler and of course, STi badging. After the fenders were rolled to perfection, the WRX was shot in a fresh coat of PPG Platinum Silver paint to wrap it up. Going Pro: Erick Davis' 2002 Subaru WRX

Inside the cabin, the upgrades are primarily JDM STi goodies and the aforementioned Prosport gauges along with Prosport’s factory matching aluminum dead pedal. But Davis is a sucker for a good audio system and sided with Alpine Electronics to make it happen. The system is built around the Alpine iXA-W407 Digital Media Station with an innovative Alpine KTP-445 mini amp lurking behind it to power the SPR-17C 6.5-inch 2-Way speakers. The lows are shipped to an Alpine MRP-M500 mono amp to spark up the Alpine 12-inch Type-R subwoofer in a custom Audio Integrations enclosure.

As a regular daily driver, Davis has something special here. Sure, the car isn’t going to kill it at the Time Attack or drag strip, but he has a nice all around cruiser with all of the gadgets and luxuries.
