1. Honda Sportrax EX400
This system allows you to keep the same displacement, bore & stroke, and compression ratio as the stock set-up. With a minimal weight gain of just 20lbs, this kit will generate nearly double the horsepower! With the estimated 12-14 psi of boost, an increase in carburetor throttle size is required - from a 35.5mm throttle body to a fuel injected system with a 40mm throttle body to handle the increased boost. This is some major power you will feel in the seat of your pants!
- Model years 1999 & up
- Featuring the Garrett GT12 Turbo
- Direct Bolt-on with no engine mods
- Was $4,408.95
