You might have to change the fuel pump and ofc the gearbox. But yes i think. Not really awake atm.

Engine is a straight swap yeah.
Will probably have to use the 1.6spi loom though as it has a few extra things compared to the 1200 engine loom

will it not run on the 1.2 loom with the 1.6 ecu?
Adam

As said, the 1.6 has stuff like EGR, whereas the 1.2 dont. So the 1.6 loom is different.

1.6 spi.... thats got to be one of THE stupidest conversions ever!
Sloth
09-02-09, 08:57 PM
why its an ok lump and not that slow
Adam
09-02-09, 08:59 PM
Its a ****e lump, and slower than a 1.4 8v mpi which costs half the amount to tax and insure! lol

only reason i wanted to do it was because its not that much work. i dont want to do a big engine conversion. ill just stick with my original idea then, rebuild a 1.2 engine that im getting. new bearings/gaskets/seals etc... then drop it in mine.

keep it a 1.2i you will never insure an engine conversion at 17

use the 1.6 engine but put carburettor on like the old cavaliers i did this on my first 1.2
Sloth

yeah but the spi is set up to run injection, not carb. oh and try and find a cav 1.6 lump.....
