Just the s5 turbo on your six port SE? Or an S5 turbo motor in your SE?
If the prior is the case then you might need a custom header because fc turbos were four ports, compression issues might also be a concern.
From waht I've heared the SE tranny and rear end are fairly stout. thay should be able to put up with 250hp or so without a problem.
As far as injectors, I'm not shure what size the SE came with, but I'm sure if you turbo your current motor you'll have to add bigger/extra (if not both) fuel injectors, and maybe a stand allone fuel system.
But I don't know for sure as I have no spacific experiance with this sort of thing and am just blabbing
Good Luck

You only have 2 injectors on the GSL-SE. They are 680cc. You are going to need to address this issue with forced induction. You will also need to upgrade the fuel pump.
Aside from a couple of minor things, the tranny is really no different than a nonturbo 2nd gen tranny. It won't last long if you drive it hard. It's reliability is directly proportionate to how you take care of it. An option that you can do is to use a T-II tranny. You will need a custom driveshaft, T-II clutch/flywheel, slave cylinder, and starter.
You should definitely change to a standalone ecu before you add a turbo. The stock air flow meter only has 4 sqyare inches of airflow and this is through a spring loaded door in the airstream.

As stated above,youll need to adress the fuel and air delivery systems if you turbo an SE engine.
The SE rearend is no different internally than the regular 84-85 1st gen rearends,except for a slightly shorter ratio(4.07).They are pretty strong so long as you dont abuse them,mine has held up to almost 4 years of 300hp driving.
Dont expect the SE tranny to last long unless its in very good shape.

tranny life depends on how you drive it. if you shift smoothly itll last for a good while. if you are dumping the clutch constantly it wont last long.
same goes for the rear end.
my stock tranny and rear end have held up to 12 sec 1/4mi passes without breaking.
you can buy an AIC(additional injector controller) and add an injector somewhere for about 500 bucks. that includes the aic injector and getting it installed.
you dont have to worry about running lean then. you also have to drill your front cover for an oil return...and a few other things.
theres some good info on turboing 12a and 13b engines on mazspeed.com in their boosted stuff section.
