alright i still have questions with the other post but since i dont know the answer to the question in which i have yet.

what do you guys recommend me doing to increase my hp/trq while my engine is dismantle at this point. keep in mind i gotta still meet california smog rules. i heard that i can bore out my block for larger pistons and as long as i dont touch the crans ill be okay with the carb rules, i guess i could look into carb legal crans too. just want to know what kinda of things are i can go to guys

If you planned on getting the Ripp Mods Supercharger for the 5SFE, your stock engine internals would be fine. Getting a heavier duty clutch would be a good idea to handle the extra power, but supercharging wont immediately require any extra internal work, unless somewhere down the road you have the money to get forged pistons and rods, along with new valves and valve seals.

But thats only really neccesary if you plan on turniing up the boost significantly. Staying on top of engine maintainence and not running lean is your best prevention against things going wrong. This, to the best of my knowledge, will set you on the right path to keep your engine running reliably.

EDIT- Increasing the bore and stroke will not in any way strengthen the engine. Your crank has plenty of strenth to deal with boost at least to a humane level, however getting stronger and lower compression pistons and forged rods would probably be a wise upgrade when dealing with lots of boost, along with new or aftermarket valve springs and seals.
