70700 yenfor Pro V(or 107000yen for Pro L) HKS head parts no cams+ 877800 yen step 3 hks kit also will need to find an N1 Block
1600000 for an OS 3lt kit + say 200000yen for head bits and pieces
So not much diff. As had been said just pick one and go nuts.
I like OS kit with HKS T04Z kit with 1.0ar or a ITS custom turbo with titanum comp wheels
