Opinion:

The way I've seen cars turboed is by the fitting of a suitable shaped length
of exhaust pipe to connect the manifold to the turbo,..then another piece is
bent-up to connect the turbo exhaust output back down to the Cat-convertor.
This is an easy job for an exhaust place once you've decided where to
position the turbo,..how big its input and output diameters are, etc etc.

The way I would approach it is to have a look at the Burien Turbo mod to the
5SFE or 2.2L motor Camry.
Theres a bit of BS around about the 2.2 not being able to handle high
outputs due "thin blocks" which is a critisism of the block's strength under
high power. As power level rise the block has to *hold everything together*.
As another example of this type of comment, the last Ford 351Clevelands were
accused of being thin castings which allowed bore misalignment after heavy
use. How true these claims are could be sussed out by having a 5SFE block
sonic tested, but I wouldn't be afraid to give one 5-6 psi straight up.
Anything higher, like 10-14psi is something I'de avoid as the engine was not
designed to be a turbo-donk.
