TOM'S only had accessories, such as oil filler caps, radiator caps, steering wheels, shift knobs, and pedals. Most of the performance parts during the 90's were available for Supra (JZA80), MR2 (SW20), Corolla LEVIN/TRUENO (AE101/111), and Starlets (EP82/91).
There were a few parts that were made for an MR2, that was interchangeable for the Celica, if doing a stroker kit. These are from my TOM'S Catalog.
