I just bought a 1995 toyota celica st yesterday and I know not 1 thing about these cars. I recently owned 2 gs-r's 95 civc hatch and 91 prelude so these toyota engines trannys and ecus are way different then what I am used to wiht honda-acura stuff. Anyways I browsed the site for a good while and now I have questions that need answred. 1st how can u tell if your car is st205 or 165 or 185, second what is the engine code for my model like in hondas they have b16, b20, b18 is its 3gste if not whats that? and please explian the 5 afe and 7afe after these r answered I will be set in making a clean jdm celica.
