eight hp
Cold Intake, Catback exhaust.... i guess it depends on how much u wanna spend!!
I went with "BORLA", it's stainless, nice sound, strong, and will never rust, and added HP.
the 2.0 had 118hp stock the 2.5L had 164 hp. Ypur question is hard to answer because it depends heavily on who's equipment you're using. (bosai versus borla) I have 94 2.5 which should have 164 hp, but I installed twin turbo w/2.5 intercooler, four inch cat backs, cold air intake, ecm power chip, beefed up axles and joints, strut tower torque rods and frame connectors. Last time I was on the dyno, it registered at 385 hp. A fun little car to drive to church on Sundays.
Anything that Opens up the exhaust will free up HorsePower. Just as important as the car needing to breath, it needs to exhale as well. So it would give you more HP over stock, as to how much, I dont know, all vehicles will vary in how much HP it will get. but for a Spirit, maybe around 10-20 if not more.
Marbas has about 2,500 Hp and 150mp. He gives 60 exp, and is level 25.
around 15 hp
Turbo or Supercharger + K-PRO chip for ECU + Full catback exhaust + headers +intake upgrade+ K-PRO tuning job.
Add a cold air intake. (4-8 hp gain) Change your exhaust. (Mufflers, 6-15 hp gain / full catback system 20-40 hp gain) High performance wires and plugs. (4-12 hp gain) Underdrive pulleys (8-15 hp gain) Super chip (10-20 hp gain)
