I've been looking for a ST184 Celica (90-93) for a while, and have noticed that 1990 Celica have a less attractive throttle body compared to the throttle bodies in the 91, 92 & 93 Celica's. The better looking throttle body has something like TVIS 2200 graphics on the top, and the other just has EFI on the top of it's throttle body. Have these 2 different looking 5S-FE throttle bodies have any difference mechanically? The newer one also looks different in size and a little bigger. The 1990 engine has some red graphics on it and the later model 5S-FE motor are just grey, no red graphics. Are the motors any different mechanically?
