I have had 9 other Subaru vehicles, this one is not a WRX unfortunately. I felt everyone already does those. I instead built a High Compression N/A Frankenstein motor. I used a 2.5 block, had a set of 2.2 heads ported, polished, decked, big cam... JE domed pistons, Eagle Rods... and a pretty cool badass sounding exhaust. I don't sound like a fast and furious drop out though. I use an unequal length header so I have that deep signature "Harley" Subaru tone.
Like $3,600 worth of go fast parts to only make 200hp and 230tq. In a 2600lb gutted shell its actually pretty quick, she is a back road curve lover.
