Get a CAI for a VW or a BMW and I guarentee you that you wont gain more than 2-3 HP from it.
It all depends on what car..a MkIII is different. You have a restrictive assembly with a huge resonator to quiet the car since it was meant to be a luxobarge cruiser. You'll find more power out of an engine like a 7M-GTE who gets only 30 HP from 7 psi of boost compared to the N/A...they came fairly corked. The Celica however is a lower end car and muffling the intake sound is much less important.
If necessary, I can provide proof. Dont get too nervous about having more to learn about cars; I have plenty to learn myself. Just picked up Maximum Boost by Corky Bell to actually learn how turbos work and properlly sizing them to my specs.
CAI can provide decent gains on most motors, the problem is many intake are marketed as CAI but really aren't. Get a tried and true CAI from like AEM and you probably see ~5-10hp
