Thanks mike, I've checked with the local machine shop, they said they could resleeve the block, but do not have experience in Honda engines since that shop is mostly for domestic.

So in short, I'd need these if I aim for higher boost:

1/. Rod - I can get my hands on Crower, but I need to re-bore for both ends.
2/. Thicker head gasket - I have completely no idea of where to look for.
3/. Adjustable Cam Gear: Should I go for UNORTHODOX RACING ULTRA-TR Adjustable Cam Gear or AEM? AEM is about half the price. Also, there's Unorthodox Ultra-TS series which is about the same price as AEM.

About camshafts, do I need to replace them as well?

btw, one quick question, how far can I go if I want it to be streatable and still knocking on 93 octane?
