Yes SR lacks the KA torque but a KA did not come with factory turbo and a proper metal head gasket with arp studs… Many recepies our there for the ultimate SR.

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… --- _[View the full topic](https://forums.speedlife.net/t/sr-black-top-turbo-or-ka-turbo/122346)._
