You'll need to rebuild the lower lateral brace because the outlet for the O2 housing will run right into it. And relocate the Power steering pump entirely, and the alternator and find a way to get the DP which normally goes under the oil pan to run towards the drivers side of the car, then shoot back in it's normal position.
But I have a manifold and Evo 8 turbo, if you have a couple grand you wanna spend on it the project. The turbo and manifold will likely be the cheapest part of your plan. Looked into it. Even considered it for a while. It's not on my car for a reason.
