i'm in the process of turboing my 94 b16a civic, eventually i want to take it over 300bhp and i have been advised that after 300bhp its a wise move to change the internals, so could u please advise me on which pistons, cams etc. to go for. also ive been looking at the titanium valves, valve springs and retainers which allow your engine to rev up to 10-10500rpm, wud it be ok to fit them or coz it being turbo'd could it lead to problems???

 

It would good to just change them anyways. Their is a lot of people making way over 300bhp with stock internals. Do a search and you will see.
