Ive got vitz manual transmission, 1szfe, i need to increase its performance, already done with plugs, free flow, headers, intake, nitrious 50 shots (DRY). Now i am willing to change its block 1nzfe. what do you people suggest? i am not in mood of swaping the complete engine, 2things matter, budget and orignality of my car...
so do you people think changing block would increase much performance? and if it so, so any rough idea how much would the block cost me from shershah ? or anywhere in karachi.
Your prompt response shall be highly appreciated.
