The goal for the car is going to be 800-1000 crank horsepower, on 30+psi.
I'm still very new to the performance mercedes side, and expect this to be a multi year project and the rest of the drivetrain will be another huge project.

Here's some pics of the car so far, mishimoto type r intercooler, turbo bandit manifold and 80mm turbo

Still mocking up some parts, the wastegate for the turbo bandit system wont fit the sl due to the steering setup, so that will have to be cut and rerouted.

Next will be pulling the head and having it checked, machined, etc. And same with the motor. Coolant passages had tons of sludge and wasn't circulating coolant well at all.
