2015 WRX Turbo Kit Results!

After straightening out some ignition issues we got the 15 WRX back on the dyno. This time it put down a solid 444 WHP. Unfortunately we have reached a point of diminishing returns, where a bigger turbo will put us into an even lower efficiency range with the heads/cams, while a smaller turbo will not be able to achieve 500 whp that we are targeting. This being the case, we are going to explore doing a BRZ head/cam conversion.
