I just wanted to let you guys know that there is now a turbocharger option for all you 2.5L QR25 Altimas. This system was specifically designed for the QR25 Altima. It is a low boost system and will add over 100 horsepower a the wheels to your QR engine.The test car was only run at 4.5psi and it picked up about 80WHP.The plan is to re-tune it at a slightly higher boost level in a week or two.Stay tuned!
