The '85 Celica GTS is known as the 3rd generation RA65.
Specs are here:

(yours is 2400cc 22RE engine, A40D gearbox, F (7.5") 3.583 diff, IRS)
It was the same as the RA64 Celica except it used many parts from the Supra (IRS, dash, seats)
Auto -> manual is easy.
You need the gearbox (W55/56/57/58), bell housing for 22R to W55/56/57/58, clutch, flywheel, clutch master and slave cylinders, pedal housing and clutch pedal.
Neutral/Park start inhibitor switch needs to be bypassed.
Speedometer drive coming from the gearbox may need to be calibrated (depends on donor diff ratio and tyre size).
Beware that Toyota gearboxes come in many variations that put the gear stick slightly forward or backward - measure before buying.
Any W55/56/57/58 can be used but beware the bellhousing are different between M series engines (eg from Supra, Cressida) and R series engines (eg Celica, Pickup).

I've got lots of manuals, microfiche, etc on the RA65.
Just ask if you need more info.
