checking out some pistons this week or next for my b18c1 motor.(using stock rods)

1. floating pins(pistons) can work for stock connecting rods or only on aftermarket rods?
im under the impression from looking at IB probe piston section, that for stock rods only press fit pistons.

2. 12.1 -12.5:1. to run that compression , what would be best to use or what would i need as far as tuning aids?

hondata be best or something like ERE reprogrammed ecu or stock ecu?
additional stuff like adj fpr- bigger injectors etc.
would that be needed or is that dependent on type of cams?

basically will be a street car, dailydriver, 93oct gas

finishing rebuild
bored/honed block(81.5mm) original pistons sold
for cams (dont have yet)either skunkstg1s or typ-r
sx fpr
motors fairly stock

any suggestions/advice or feedback welcome
thanx
