OK... lets discuss K24 peeps...
From what i gathered from previous onwer of my car, a basic setup can be done for less then 15k. He said get k24 RBB block, as it needs minimum prep and can safely run on stock internals (rods and bearings). The RBB block has squitters and has higher stock redline compared to other k24 blocks @ 7100rpm and its almost a direct bolt on block. But u'll need forged pistons and have to have it balanced and throw in a block guard for added comfort.... i recon this should be enuff, unless u wanna go sky high 9500 rpm!!
