if this is a metro your putting the engine in its not really worth the trouble
your going to have lots of issues, the storm engine is actually made by isuzu so nothing is going to bolt in, will need to make your own engine mounts and spots to mount them, none of the engine wiring or computer will fit. you will have to have some customs axles made up. exhaust is different. shifter won't work or line up. will need a bigger radiator and car will be nose heavy because the storm has a cast iron block. skip the storm engine and put a 3 cyl back in it or if you must have a 4 cyl at least get one out of a swift GT or 4 cyl swift or metro, they are more a less a drop in and a lot less work
