i might be late , but about bottom end , accent is way better than scoupe.
scoupe piston are better but not conrods.
you are the first i see that need to replace bottom end on a hyundai engine !!!
accent conrod can support 15 psi and still far away from its limit.
here in quebec i know 8 guys running 20 psi on totaly stock 1.5L accent since years with no problem but i would personally not risk it.
hyundai accent 1.5 engine = mitsu 4G15 based. so yea , still better than honda bottom end.
but as your are going , don't push more than 10 psi to be a bit more safe.
