Also its a good time that l mention another difference b/w a celica engine and a MR2 one.
The MR2's in actual all the series have an engine mount that is on the belt cover side that is like a big banana. Well depending on which engine you have the bracket is slightly different. The Celica doesnt have one. So to do the swap if using a celica engine you have to get one. The Beams MR2 one is ok but the last hole that bolts to the above bracket ( 268 ) wont have anywhere to bolt down. Its not important as the celica has its engine hook solely supported by the alternator bracket. So either grind it off if you like, leave it as it is , or modify the alternator bracket slightly so that a bolt can be used for that finish look. BTW im doing the last option

You should know me by now

The guys that have done a celica swap would already know this.
