hello
i am kinda new to this site i have been a member for a few months like 6 and i have been doing mad research on doing a 3s swap but i dont think its what best fits my application so i want to start over and just try and build the 5s motor i have. dont get me wrong i am no mechanic but i have basic knowledge of how a motor works and i know how to use a wrench.. if replace cams crank pistons valves springs and just big items like that and then turbo it but keep the boost Psi. around 8 could i see 200-230 whp? or what would it take to get that out of a 5s? like i said i have spent all my time looking into 3s swaping so i have no idea what the 5s can do... ya i should have thought about that before i looked into doing a swap i know but ya to late so any advice would be nice. thanks

#1, if you have an ST, you have a 7a motor, not a 5s.

i think u can get about 150-160whp(proly a little more) on 5sfe w/o nitrous or turbo....but good luck on producing 200+ whp
complete airflow upgrade (cai/exhaust/header) ur jus looking at about 10-12whp so if u get cams/ecu/port polish proly another 18-25whp...

stock healthy 5s ur lookin at about 115whp and u add 12whp+25whp=152whp
