Tommy drove from Austin, TX to AJ Performance in South Florida to get an AJP Turbo kit. He now has 421 whp and 296 ft-lbs. of torque at 10.2 psi on a stock motor in his 2007 Honda Civic Si.

The kit is tuned with the Hondata AJP Turbo reflash and the AEM Fuel/Ignition Controller. The Hondata reflash provides a VTEC engagement window from 4250 rpm to 5500 rpm. This means that VTEC can begin at 4250 rpm all the way up to 5500 rpm depending on various conditions.

AJP rescues a 2007 Honda Civic Si with a botched turbo kit installation.

Please note that AJP inherited many problems with this car. We did the best we could to solve them, but some rough spots remain.

This car was ruined by another shop that did a horrible installation of a custom turbo kit over the course of 6 months. When the car came to AJP, it already had a built motor and a turbo kit with a grand total of 405 whp. Maybe.

It was barely drivable.

AJP made many changes to the installation and tuned it up to 568 whp and 379 ft-lbs of torque at 17 psi. It is now very drivable.
