if you are going to a top mount turbo you'll need to fab up your own downpipe.

If you notice its your elbow/o2 housing that is fouling against the steering column, so once you move the turbo out of the way you no longer see that problem.

For the turbo to choose what are your power goals and what type of application use are you going for this car? (that'll direct your turbo choice alittle)

even the stock manifold and a new turbo, you still need to fab a new turbo-back section
