straight swap as your single point injection, personally not worth the bother, get a 1.4 mpi or better still but rare to get hold of is a 1.4 16v
all the corsa std engines use the same mounts, but the more powerful models use thicker shafts and the later ones 97on have different splines, but u can still use the 1.2 shafts even if going to 1.6 16v but dont know how reliable they are, just depends how lead footed ur!
What kind of changes to the fuel management would i need to do because i know 16v's have a completly different system than the 8v's. What other things would i have to take into consideration if i was going to wack a 1.4 16v in?
youd need the ecu, engine loom, igniton barrel and key and transponder module to disarm the immobiliser fitted on the previous car.
Or buy a blank ecu and you dont need the barrel and key.
Fuelling wise youll need a multipoint injection fuelpump and tank off say corsa sri/sport/gsi/cdx/any corsa with multipoint injection.
Maybe youll need high pressure fuel lines on the car due to the pump pumping at a higher pressure than the one on the car before. but usually you can get away with the ones u have.
get uprated 2.0 16v front brakes and uprated suspension and youll be sorted.
Personally while the engines out id ditch that inlet manifold on the 1.4 and fit either the mantzel powerbox or better still fit a fully mappable engine management system with throttle bodies from SBD.
All depends how far you want to go with the engine.
tbh it aint a massive job converting 1.2 > 1.4 16v
