Okay, I know the basic why... so they don't break under increased pressure... but can someone give me the details on what to change to run say 14-16 psi?
As far as I know, I'd be changing pistons and rods... but do they need to be lower compression ones? or just reinforced? and then things like valve springs and valves... do they need to be changed?
Most people say that honda engines can take around 8 psi on bone stock internals.
also how much of a hit in performance would there be running around on lower compression internals than stock while normally aspirated... as in... work on engine before putting it in, build it for turbo... but put turbo on later...

thanks

 

i would suggest new pistons,piston rings,rods,valvesprings and retainers, plus a new headgasket to lower your compression. the others on here tho kno way more bout reinforcing the engine for higher boost.

 

you just need forged pistons and rods for your setup. the thing most people dont do is get an aftermarket engine management which I think you pretty much have to have for anything over 10 psi. valves and springs can be kept stock but aftermarket ones are better. Aftermarket valves are shaped differently and flow better. Springs will save your engine from a flubbed shift or if your'e planning on revving to 9000.
