I was going to say from the first pic, it looked like you have plenty of room to work with, & it seems you found a way to have enough room.
Where the heat riser section bolts to the intake manifold. I would run a block off gasket, that exhaust manifold is going to heat up your intake manifold, real fast & at a higher temperture.
You are going to get a lot more underhood heat you will want to some how get rid of that heat.
Running a turbo gives you so much underhood heat ,you would probably want to run a hood vent or fender vents. I do not think you will do that type of mod/s to your car, just saying. You could send out both of your manifolds to get surfaced evenly to give you a better seal.
From the pic of your exhaust pipe, are you going to mount the T4 flange to the jagged secton?
If so, I would not mount the turbo that low, if you could move it up & a bit more forward I would think that would be a better position for your turbo..
