Thanks alot guys!
@qwert, i wouldnt suggest the k swap, it costs too much and its not worth it if your goals are 600+ hp, otherwsie tell him to switch the head and block to a d17 vtec, shouldnt cost more than 10k, its a straight swap, spend around 1.5 laks and turbo it, swaps can get complicated and very costly...i wouldnt go K if i didnt have plans bro 
@mominhaq, k20z3 isnt available here, and its nothing that great either
@retard, yeah the k20 is a type R, not k24, 220 bhp
