depends on your goals with regards to power output. The wrx and sti bottom ends are the same apart from the rods and pistons. The crank is the same (based on a same year comparison). If you friend is looking for 300bhp then a standard wrx bottom end is upto the job

go for the sti which has more potential in standard form
