Weakest link in the K24 would be the rods, but there are so many group buys going on right now for quality aftermarket rods for around $500 that issue is eaisly over-come. A lot of people say the bearings as well, the new ACL race bearings are supposed to be out real soon and should help with that problem. If you're a baller you could go with the crower stroker kit which would over-come all issues with a stock bottom end From what I've read the stock K-series sleeves are thicker than B-series, I know someone over on K20a.org is in the process of a turbo build and plans to run 20+ psi on stock sleeves.. we'll see how it holds up.

I priced it out and to put together a turbo setup like the one above it would only cost a little more than going with an SSR header and a set of ITB's.. for the most part everything else would run the same, ie: cams, springs, retainers, fuel setup, cooling system.. only other difference would be that low compression pistons and turbo rods would cost less than the IPS spec. pistons/rods (IPS pistons would be required to run 50 degree VTC on K24 w/there cams, there rods are just highly recommended..) So all in all, it would probably even out...
