whats the cheapest ways and parts to put in my 06 civic si for the most power?

Speed costs money. Get used to it. The most power per dollar is nitros.

Quality cold air intake and full exhaust will net you 20 horsepower. Nitrous is the most bang for your buck, especially if you want to shorten the life of your motor. You can safely do a 50 hp shot occasionally. Turbocharging is my favorite, providing a middle ground between high horsepower and engine wear, 100hp, easy. Supercharging is similar to turbocharging, but less hp also translates to less wear on your motor, maybe 80 hp. For under $100 you can put a cheap fart can and short intake for maybe 5hp.































Real speed costs money. There is a reason many people start with intake/exhaust. It's cheapest and easiest. They are not all created equal, and may be a waste in the end.

there is no cheap way















and btw the person above me















intake and exhaust wont get him 20hp















proven on my car dyno'ed































he may hey 10-15....















































good quality parts cost money















never EVER go cheap on parts















why do you think some exhaust cost















900+















compared to 200 or so































material quality...































i learned this the hard way

maybe a turbo might help.

How do you define cheap? Sure you can go get a QUALITY intake/exhaust/header combo for you car for around $1,000, and add 10-15 HP at the wheels, or you can spend $4,000 for a QUALITY turbo kit and get 100 more HP at the wheels. Now dollar for dollar that is $100 per HP with the i/e/h route or $40/hp with a turbo setup.

If ur looking for REAL power and not just the 50hp +/- u get from bolt ons go turbo. With $1500+/- ull be running over 250hp at the wheel.
