some people swear by block guards, some swear at them... Its probably better than nothing, but you may have coolant flow issues. If you have the time/cash, sleeving is really the only way to do it right, especially if you plan to overbore.

As for cams, theres nothing better than Crower... I'd call them up and tell them what your goals are, and just get whatever springs they recommend.

The Eagle H-beam is a great budget rod (I wouldn't call them super-strong... maybe medium-strong h: ). They regularly go for around $300 a set, and can hold any kinda power you'd generate @ 8psi (or 15+ psi, for that matter).

:edit:as for the c/r, you wont be making much power until you boost the bish @ 9.2:1...

If turbo is really the final goal, I'd reconsider the cam thing... turbo cams really aren't necessary until you've gotten everything else taken care of and you're at pretty high power levels. Stock cams are pretty darn good for streetable turbo setups.

:edit: :edit: Were you planing on using stock pistons? If so, they don't really work w/ aftermarket rods (they can be machined to, but generally not a good idea). Good rule of thumb: stock rods, stock pistons; aftermarket rods, aftermarket pistons.
