ok, in my opinion, you have to make a choice NOW before you start building for two reasons:

1) If, like you say, you may never turbo, you're not gonna make any significant power at 9.2:1 compression ratio. You will have just wasted all that time and money on headwork, forged internals and assembly. Basically, you'll still be slow, only you'll be poor too.

2) The cam thing also seems like an awful waste of time and money if you end up boosting. Plus, aftermarket n/a cams are generally designed to work with a higher c/r and wont make much power at 9.2:1.

I think you should decide right now if you'll turbo or not, before you waste a lot of money building up a block that will perform essentially like stock.

The other option, of course, would be to build for turbo, and then just nitrous the motor until you can afford the turbo equipment. Building for turbo and nitrous is essentially the same process, and the same principles apply (lower compression, stronger internal components, reinforced sleeves, etc).

BTW: Sleeving generally costs around $1000 (plus shipping costs). The best route would be to have the sleeve manufacturer install them themselves--major peace of mind factor there (the most common cause of sleeve failure isn't huge boost, its poor installation). PM westcoaststyle if you decide to go this route... he's in with the AEBS guys. Of course, if you decide to stay all-motor, sleeving wont be necessary.
