This one is pretty simple. You only need a handful of tools to do this and about an hours worth of time.
1. here's my old dnp manifold:
2. Comparison (dnp vs. ported 2g vs. fp)
3. unbolt your intake pipe and remove from car.
4. unbolt the four bolts holding your turbo to your manifold.
5. unbolt the 9 12mm nuts that hold the manifold to your head.
6. If need be, check your threads and studs of the 9 OEM studs on the head. If they are stripped, wobbly, etc, this is the best time to rethread them. My choice would be an 8x1.25mm tap or a metric helicoil (depending on how bad the threads are).
7. Reinstall your manifold gasket. I chose to put copper RTV on there for good measure.
8. Mock up the manifold on the head/manifold studs and put your new OEM turbo bolts into the manifold and mock up your turbo. REMEMBER TO USE NICKEL or COPPER ANTISEIZE!!!
9. Fit everything up and tighten her down.
You should be good to go!
