http://ajperformance.com - AJP turbo kit makes 437 whp on a 2008 Honda Civic SI with a fully-built motor at 14 psi.

Tuning is with a Hondata reflash for AJP turbo kit and AEM Fuel/Ignition Controller.

This was our first car with the stock kit and fully-built motor using the AEM Fuel/Ignition Controller on top of the Hondata reflash.

The Hondata reflash is good only up to 8.5 psi; the AEM FIC is used for the additional psi.

Boost and horsepower will be increased once motor has several thousand miles on it.

  • is there a way to get rid of the limiter at 6th gear..because i find it annoying when i beat other cars only to have them beat me at the end because they have 140's on the higway...

  • @dilirent What are you using for tuning?

  • At what hp do you have to build the motor on these cars? What turbo do you use on this kit?

  • @cmiller8006 Over 500 whp is when you build the motor. We use the Precision Turbo 6262s.

  • @ajperformancecom Nice. What about tranny? And have you guys ever done any drag racing with any of the higher hp cars?

  • @cmiller8006 Stock tranny. But we have found that they break in the higher horsepower cars, so we're getting gears.

    Our shop car was in the mid-600s when it ran 10.97 in the quarter-mile. We're going to turn up the hp once we get a better tranny.

  • Another AJP great build. Nice job guys and great build! I like how you guys are safe with breaking the motor in etc. Think about a turbo kit for a 1999-2000 honda civic si B16A2. I know that B16A2's are older now and the money is in the newer cars but you are getting amazing results in the newer civics and I would love to see some options for that motor as well. Great build and thanks for sharing!

  • What's the offset of those stock si wheels

  • Got a question what are the offset of those stock wheels

  • BEAST

  • @ajperformancecom lol your not running 500hp on a stock block

  • dont waste your time...click at 2:35 to go from 6 to 12 haha

  • Awesome power I bet that's a hand full to drive.

  • is this car structure prepared for those 437whp? cause i can clearly see the structural twists at the engine peak power output...looks like a car with an insane power over a....stock civic si chassis. @jacknsally218 true! lol

  • Love the color ;) /watch?v=-7Bog3_eIFY
