2002 Subaru WRX – EJ207 Swapped

Subaru | WRX : August 29, 2020

When it comes to Bugeye WRX power plants, it really is hard to top the EJ207: out-of-the-box 8,000RPM+ redline, semi-closed deck block, AVCS intake camshafts, no TGVs, and in the case of the Version 8, a rumble-eliminating header feeding a twin-scroll IHI VF37 turbocharger good for 300awhp+ -- in short, it's one seriously fun package! And that's exactly what Blake brought us his 2002 Subaru WRX to have done!

With the engine in-shop from J-Spec Auto Sports Inc., Alex got to work performing the swap including a twin-scroll specific down-pipe from Tomioka Racing, timing components from Subaru and Gates Racing, OEM STi Group N engine mounts, an EXEDY USA clutch & Fidanza Performance 9.5lb aluminum flywheel, necessary wiring modifications to enable AVCS, along with all the miscellaneous OEM Subaru gaskets, seals, fasteners, and components to complete the work.

From there, Matt strapped her down to the rollers for Vlad to perform a custom calibration via EcuFlash (open source). With 93 octane in the tank, Vlad increased the EJ207's output to 306.99awhp & 309.40lbft, a peak increase of 104.42awhp & 87.36lbft over the baseline of 205.52awhp & 222.04lbft, with gains of over 160awhp in the upper end of the curve! It's easy to see why the EJ207 is a go-to solution for GDA/GGA chassis WRX owners looking to turn the wick up.
