dude a gt2876r is a universal turbo i.e it is made for any application. it uses a t25 inlet flange, and a 5 bolt exhaust flange
There is a lot of work in fitting a garrett turbo to a subaru.. and its not cheap or easy! nothing comes off the shelf
you will need to purchase these items
- t25 flange and gasket
-5 bolt exhaust flange and gasket
-oil feed nipple, braided hose, fitting to block
-oil return flange and gasket
-water feed fitting and hose
-water return fitting and hose
you will also need to twist the new turbo as it wont fit well in stock location, which will require:
-custom fabricated up pipe
-custom fabricated down pipe
-custom fabricated intercooler pipe (from turbo)
-custom fabricated 4" inlet pipe
ALSO.. your stock ECU will not run the gt2876r, you will need a programmable ecu.. ideally bigger injectors, link ecu, 3" exhaust, front mount, and you will also need a tune, preferably a dyno tune!
