Illegally, just add a set of headers and a nitrous oxide system with fuel enrichement. Thats 295 to 325 hp net at the flywheel, enough for 13 second standing starts.
There is nothing else that will hit as hard for the price.
Superchargers are bolt on.CAPA's inventory of chargers are the ultimate bolt on, but they don't give you globs of low end grunt. If you don't have 6k to spend, 800 bucks on nitrous is the only answer.
Warning, though. Some states whollop ya with a defect or canary if they see it hooked up on the street.
Stock EF's have about 200 to 220 hp. A 9 psi CAPA boost is 320 to 350 hp. And its able to be sold off for 50% of its cost when you come to sell it. Considerniong the depreciation curve of a modern car is so huge, loosing 3 to4 grand on and eight grand supercharger coversion isn't so bad.
If you get a Kyver 2800 rpm stall converter, you will spend 8 grand and have a 13 second street pounder you'll just love. Without the converter, your car will never see the extra grunt the supercharger has.
If your ride is manual, then hopefully the T5 will hack it.
Whatever, you have some options to mill over, and best wishes.
