yes somebody does make a turbo for the d15b7. Edelbrock has a turbo kit called the Performer X for the d15b7 engine. it is also emissions legal. I have this on my car and i have the boost set to 8 psi. It has never hurt my engine ever. It also comes with a tuner box that will set up a turbo for a stock engine. Here is the link.
