1.0 - 1.3 fuel injection

hey guys, i have a little 2001 993cc swift,
it has a SPI system, im not too sure if anyone has done this but if i remember correctly, the 1.3 8v swifts are also SPI? just wondering if anybody has put the 1.3 unit onto the 1L, quite certain the injector will be bigger for the 1.3 and so will the throttle housing. would be nice if the 1.3 bolted straight onto my inlet manifold,
let me know what you think peeps! cheers
ollie.
