well the apexi itself isnt hard on your engine...i was just saying trying to get 20 extra horses out of a stock celica is a little much and i'm sure it'd have to be putting extra wear on your engine.
with an Intake
an exhaust its not THAT much of a strain. thats pretty good power extraction considerring most Intakes
will give you 2-5 horses pure bolt-on and most exhausts will give you 3-6 hoses pure bolt on. so the super fc (if it was actually Intake
an exhaust) just "gave" that car about 12 horses. not bad
