Hrm, not sure, but I'd guess you'd need a 1.8l bellhousing at least. That would be the easy part... then you'd need (probably custom made) motor mounts... the sport has a wider chassis.
Now the fun starts, just seeing the pics you'd need:
timing chains/tensioner/cover (this carries oil & can leak)
intake manifold & all its related sensors/injectors/fuel rail/fuel pressure regulator etc etc
exhaust manifold & w/e it would take to tie into your exhaust
water pump
oil pan
egr system components
ECU & complete wiring harness & then custom wiring to your dash harness
COP's x4 at $100+ each
MAF sensor & intake/filter system
Proper fitting Alt/PS
This list is sorta tongue in cheek cuz it's probably not even CLOSE to complete!!
Long story short, you'd be doing a total re-engineering of your current vehicle. If you were even seriously considering it, you should start with a running wreck donor Sport & even then it'd be way easier to swap tubs than to start with a block & try to make it work... They really are vastly different systems.
Me?... I wouldn't touch it. I'd contact the seller & get him to take it back... then find a good 1.6 8v & go to town.
Someone like ebewley who actually does this kinda crazy stuff (after all he transplanted a 2.5l V6 into GODZUKI2!!) could prolly make it work... but I'd betcha he'd start with a complete engine/harness & ECU at the least!!
HEY ERIIIIIIIIIC!! Chime in & tell him what this would take please!!
