Would this turbo work in this car?

engine displacement or 2.3 vs 2.4 is not a good way to judge this. displacement is based on bore (piston size) times stroke (how far that piston travels top to bottom). the engine could be reversed combination smaller pistons longer stroke or larger pistons shorter stroke 3x5=15 5x3=15 as well. the amount of compressable surface for a 3" piston would be much smaller than a 5" piston. does this make sense? the mercur (i used to own one) was a strong top runner a bit lagging in low end. additionally this engine was based on a solid foundation (fords pinto and mustand 2 4 cylinder) the engine was a cast iron block aluminum head arrangement. it was inner cooled as well and recomended to be again. your scion is front wheel drive as well and the xr4ti was rear so if it were to somehow get set up expect poor traction as you have no weight transfer. dont get me wrong I love the turbo's but boost preasure is everything here and clowing pistons thru the side isnt a good idea. by the way I also had a Ford front wheel drive turbo'd car probe gt and it was squirelly from a dead stop. no stearing and little traction. the xr4ti was a totally different feeling car to drive.
