ok, basically to answer your question, your 5sfe will fit into any celica from 86-99. most celica's came with the 5sfe. BUT!!!!!!!!!!!!!!!!!!!!!! there were some celica's from 86-99 that came with the 4afe or 7afe motors. they were mostly the celica st's. these cars had different front subframe's. so putting a s series engine in is a pain in the ass. you can tell its a st becasue they had drum rear brakes. most gt's and gts's had rear disc's. try and make sure the car you are getting is not a st. it will make your life alot easier.
