Well lets see it in this forum the reason the car was sold? Probably problems. First the car is running of a supercharger mostly likely a Jackson Racing one takes over the intake manifold area, or a Vortech style which looks like a turbo but with belts attach to it. That alone is putting strain on every single part of the motor, trans and axles items. Then the car is turbo add more to this mix. And you need this to be your daily correct. So your SC boost 6pounds and your turbo 6pounds. Doing the match 12pounds but not all 12pounds get to the S/C since S/C takes over the intake part you probably see 8-10lbs of boost give or take.Now you didn't state if the car had forge items and or if it has an aftermarket clutch axles fuel injectors and ingiton system. What is the fuel management AEM or FMU? All these question are important is it tune? How long has it been boosted? Did you take to another shop to take alook at it.I personally wouldn't get it because the fact that it has S/C and Turbo at the same time not sure how good the install was and if it was good I'm pretty sure it be kinda of a famous Honda in a magazine or something. If it was either or SC or turbo it would be a great buy. And how much are they asking?
