ok ive searched and am still at a lose for an answer which would end up being cheaper and i plan on doin all the work myself what exactly woul need to be purchased for both i know that i would need a turbo for the KA and i would be planning on getting black top front clip if i went SR the front clip ive found is $2300 and i dont know what i would need to purchase to get either running. ive been considering using a nitrous(sp) system in either so if any requirments to safely use the nitrous(sp) would be needed this would save me from having to replace parts have way through the build up
