The 16" turbo 2 wheels wont fit on your car I dont think. Only the GXL, T2, and convertible were 5 lug. And to put in the T2 motor you need to get:

Complete turbo engine with intercooler

Left-hand drive spec turbo wiring harness

Turbo ECU (jspec ecu will work, as well as convertible ecu of the same
year range)

*only for 87-88 turbo* knock control box, a small silver box up inside the
passenger kick panel that plugs into the wiring harness. On 89 and later
setups, the ecu handled this function.

turbo boost sensor.

Turbo throttle cable. 87-91 are interchangeable.

Stock turbo fuel pump (87-91 turbo pumps are the same, but the bracket is
not) or upgrade such as walbro 255. A rewire for full voltage from the
fusebox is also recommended, as well as a re-ground in the hatch to bare
metal, a new pickup screen and fuel filter.

Stock turbo intake duct with blow off valve (if not present on engine
already). The 87-88 TID is smaller than the 89-91, but either can be used
in place of the other. Blow off valves are slightly changed but basically
the same.

Stock t2 precat/downpipe and midpipe (bolts to main cat) or
aftermarket/custom equivalent.

T2 hood with scoop (unless you go front mount intercooler from day 1)

Turbo air flow meter (your old nonturbo afm will get you by if you cannot
find one, however the turbo afm is said to be calibrated for slightly
higher air flow on top end so it is something that might matter once you
begin to push the car).

Aftermarket boost gauge is recommended. Even though 89-91 owners can
install the 89-91 turbo gauge cluster and the gauge will work, it is still
not very helpful. 87-88 owners cannot install the stock turbo gauge cluster
and expect it to work, the wiring harness differs in this area.

Aftermarket upgraded clutch and pressureplate. Remember, you're buying
this for a nonturbo, not a turbo, since you're using your old NA drivetrain
still.
