Not True^ maybe with SSAC Parts, but bottomend internals the right one will cart around $1500+ and sending the block out to the machine shop and also crank to get balanced and blue printed because if your gonna turbo the ka you gotta do it right! dont forget about cams and a metal headgasket and arp studs-$550+ now the manifold will bearound $400, turbo-$800+ depends what type and sizing! your already 3K so a ka24det build up is NOT Cheaper but horsepower and Torque are greater when boost #'s are applied. But also Sr's rev higher faster and the drop Rmp faster alot faster than a KA. Both motors have there plus and minus, Go with what every you have the money for and are looking for as such power, tourqe, reliable, and vechile application! either one is a great motor, ive done both setups i went from an sr to about 5 ka-t setups and now im back to an SR and i love it but ill tell you one thing I miss the Torque of my KA-T!
