Case had two helicoils due to broken intercooler bolts. All blower to IC bolt holes were drilled and tapped to allow a larger 6mm allen head bolts from Proweld Performance. These bolts are reuseable and will not break like the stock 5mm ones. One hole looks like its buggerd up but it holds a bolt just fine. I was going to port this and swap my rotor pack over but decided to focus on suspension instead. Feel free to ask any questions.
