[SOLVED] What's the best way to reinstall the engine

Helping a buddy out with his build ( @Chemmedic ) neither of us have done this before, we're prepping to put the engine back in, the question at hand is: what's the best way to put the engine back in?

What I mean is should we: bolt the turbo to the DP and then drop the engine in ontop and just tighten to DP to mani nuts and then plumb up turbo (put on as much as we can beforehand to turbo)

Or bolt up turbo fully to engine and then bolt turbo to DP once engine is in the bay so that we can plumb it up a little before inserting the engine

Or bolt turbo and DP to engine then insert it into the bay as one unit?

Open to any other suggestions. Keep in mind DP will be 3" CNT catless long DP

 

This.

 

No clearance issues even with the tranny on as well? I presume not if you're recommending doing it
