well guys, pls dun get me wrong. im not saying Na is no good but thn to me it sound like real enthusiasts game with big roller. if budget kids like me, i always go for the item or setup which spend the less, gain the biggest.
moreover, most power gain on Na was on high rev range. on those u need a good set of cam (trade off idling) and cam components. for na to have good low respond, you need big displacement but how much cc we can gain in our tiny motor? i guess this is how american muscle enthusiasts slowly going to japan turbo machine. look at how how fast is JDM market grow in US and UK
