400hp STI

My old 2004 WRX STI fully built ej257(dual valve springs and titanium retainers with bronze valve guides, BC272 cams, forged pistons, H-beams rods and nitraded crankshaft) this is just the basic things that were done ... still stock turbo and injectors.... she was making about 20psi peak. This set up was ready for 500whp and it was my next step to get it there but i sold it summer of 2017. I will buy another one as a daily soon again.
