My end goal for my wrx is to get to 350whp. I don’t think that is too unrealistic. E85 is also the end goal to actually make that power. So a pretty nice size fuel system for e85 and I have a VF39 with supporting mods. I have the stock ej205 and I would like to upgrade so I can pass the 300hp mark reliably. Should I build an ej205 or throw a 207 short block in and recondition the stock heads? I’ve heard good and bad things about both. Any unbiased opinions would be much appreciated.
