first off, you can't post up a question and phrase it as a put down and expect people to be happy with what you have done... like above i think you don't understand that *most* of the people who build a ka-t don't ever even dyno the damn thing. i never have, my ka turbo is faster than my brothers s14 sr (you know the one with variable valve timing and higher stock horsepower than the red top...it is stock by the way and we are both on ~7 psi.). i just don't understand at all how you went from "all you ka guys are losers who don't make power like sr guys" (which is total bull crap as everyone above has shown you) to hey i want to build me ka turbo... next time think before you type, please.
umm check out this site for a bunch of guys making lots of power from their ka's...

a ka turbo, regardless of the power, can last as long as the stock one, as long as you don't boost it up off of every light and drive like an idiot all the time. you have to take care of it with regular service and even more attention to little details than the regular engine because of the nature of turbo cars. with a good tune many people have their turbo ka's lasting years and years... it's just like every other engine, the more you abuse it, the shorter it will last.
