here's a little trd prep guide i found in the aw11 faq:
When I purchased my new engine (4AGE) from a guy who used to Race Corolla GTS he gave me a TRD engine/suspension prep guide for the AW11 MR2. I believe it is from the old TRD catalog aroud 1990 maybe ?? It gives a brief history of the MR2 and the 4AGE as well as the 4AGZE.
The Catalog rates the MR2 in the various SCCA classes never giving it less than an "A" grade this being if all drivers were equal. It has a vehicle preparation section which lists mods in two phases. The first phase is titled Street performance. This section says
Phase One: STREET PERFORMANCE
Results: Slight decrease in ride quality, improved handling, improved brakind 10-15 hp increase.
TRD Springs TRD Adjustable Swaybars TRD Low pressure gas strut inserts TRD Brake pads TRD Brake line kit (drain and install ford type fluid) TRD Header and Exhaust System High Flow Air filter Recalibrate fuel injection system (See Engine Preparation Section)
