Increasing Horsepower/Torque in 5sfe? Options

[RyuCelica]

Hi everybody,

I'm pretty much a noob when it comes to tuning engines to increase speed/horsepower. I have a 94 Celica GT with a 5sfe engine. I want to increase the power but I'm not looking for power that a turbo or supercharger would give. I just want to increase the horsepower by as much possible without turning to a turbo or supercharger. Basically. I just want the Celica to run a bit faster.

So my question is: What do I need in order to increase the horsepower/torque of my 5sfe engine without looking into turbos or superchargers?
My starting point is exhaust headers but I don't know what else i could get.

Thanks!

There is no real way to gain power with the 5s. I had a Weapon-R Dragon intake and an e-bay header on mine and while that made is sound a lot better than stock it didn't do much for performance.

If you're looking for SPEED (vs specifically horsepower), your cheapest route is free but depends on how far you want to take it. Lose weight (spare tire, jack, repair tools, rear seats, etc.

Your rims look very nice but if they're larger than the stock alloy 15's they're probably adding about 20 pounds of unsprung weight to the car, which is about 2-3 tenths when you're looking at a 0-60 time.
