Got the compression and leakdown from SoS, it isnt actually that bad, just showing its age.
Looks like it is a better value and more reliable for a custom sleeve and pistion over doing a new short block from honda. Ive been talking with Jeff at SoS on what to go with and he has definitely given me some great ideas.
Im going to go with SoS's custom engine sleeving service, 89mm on the pistons a good idea for power and reliability?
BC Rods, Moly coatings on piston skirts, refresh the head etc.. what else should I look into while its open?

Seriously. If my motor blew tomorrow, this is what I'd do.

Honda Tuning a few issues ago or maybe even about 6-8 months ago, cant remember. But it has been done.

In an S2000? I know KevoS2K did the swap but I'm still not convinced it's the best way to go for making NA power. In the end, you're still building somewhat of a Frankenstein engine that is bound to run into numerous small problems that will add up quickly. I'm not doubting the capability of the K series or anything, just wondering if it's just hype or there's a complete benefit regarding all aspects of an engine build, not just the numbers seen at the end.

Ya this is my guess, but sleeving the block and going with new pistons cant really be a headache if done correctly right? Supertech head work was recommended but by the sound of it ill just stick to stock springs and retainers, possibly supertech valves... then maybe OEM is the best bet.
the valves are what failed on my car made by supertech, ferrea valves are the only way to go in my opinion. the stock valves are 2 piece valves and i would not put oem valves in a boosted motor, it was my own fault for thinking that the supertech valves saving me a few bucks cost me a motor.

check this thread; http://honda-tech.com/showthread.php?t=2624937 headwork does include more aggressive cams. This setup and some e85, you can't tell me that wouldn't feel nice in an S.
As for the end all to NA power, the K is a silly way to do it. If you're serious, this is the way to go;

@op
Another plus, you can sell your engine for 2k to add to the budget. There's the cost of the kpro, clutch and some mounts right there.
The highest power someone was making in that thread is 306 whp on 93 octane. This again is in a FWD car so I'd expect somewhere around 270 rwhp, which is just about what James was making, albeit on a Dynapak, but again, this was the highest number in the thread. The rest are somewhere around 260 whp, or around 240-250 rwhp which can be attained with ITBs on an S2000. A few years back, there was someone "local" with a 2.4L F series making around 250 whp. It would be a lot of fun to have a 300 whp NA S2000, but I still don't believe a K swap is the most economical and reliable way to do it when you already have an engine that has amazing volumetric efficiency and reliability from the factory.
The LS swaps are nuts!

Your rebuild include pistons and sleeves? Stock specs are definitely the path im aiming for, I am tempted to use Supertech dual springs and seats with Ferrea valves, I did alot of reading lastnight after subes post and that combo seems to have stock reliability +1.
Are you E85 or turbo? I was told the 91 pump is largely my worst limiting factor.
