Dont you have to purchase the SR motor WITH unknown MILEAGE and ALL the other supporting mods (intercooler,piping,bov,exhaust,manifold,injectors,fuelpump,piggyback ecu/standalone,nice mild cams,etc) lol …and if you want big power a bigger turbo than stock??? my point have always been that instead of buying a used motor do a refresh on a ka longblock with forged pistons metal head gasket,arp head studs and your set for around the same money,actually LESS. Dude u got to buy the USED SR 1st for like $2000 or more then buy the same stuff/supporting mods as the kA anyway and at that point they will both make and handle 400whp except the KA will have about 1000km`s or less so do the math bra…
