Just wondering if anyone knows what the safe reliable power would be hat you could get from the EJ20Y engine thats found in the 05 jdm legacys. Also if i wanted to strengthen up the internals what would be needed to build it to take a reliable 450-500bhp, or would that kind of power blow the hell out of the 5 speed gearbox? How much would parts cost for such a engine build? Im just thinking of maybe keeping this car for a few more years and up the power levels a bit for some fun!
