More details on the kit. Who made the kit, what kind of turbos?
That check engine could be on for alot of reasons. But it does suggest, things are not so neatly done.
Does the car have any engine work done to it? With the stock hypereutectic pistons in the mod motors combined with the metal headgaskets they run, you can run into some trouble if you detonate.
Figure a turbo kit is going to run about 6K when it is all said and done. For that you get a really nice one.
