hey i was thinking about doing this to my S13 SR20. has anyone bored out their sr, or gotten a stroker kit? how successful were you? how safe do you think this is (would the cylinder walls become to thin)?

also after talking to a mechanic, he said i could expect to get 200 extra horses out of the kit giving me around 550 on 14lbs of boost. i just put in a spec stage 2+ clutch, but other than that my drivetrain is stock. with the increase in power and torque would the tranny, driveshaft and everything else be able to handle the increase? or would i have to upgrade even more?
