90 to 94 Engine block swap

Is their any differences in the 1.0L 3 cylinder Engine block or heads from a 90 to a 94 Metro?

Thanks,

I don't think you will have a problem. 95 and up have a crank sensor if i'm right. i put a jdm in mine about a month ago. pretty straight forward to do. 89-94 should all be the same if they are both 1.0. hope this helps. someone correct me if i'm wrong.

A G10 block is a G10 block. They are all the same. Heads are the same too except if one was a XFi model the cam would be different, but it would interchange. There should be no electrical difference between a 90 and 94.

you just have to use the intake system off the one that came in the car your fixing and probably the distributor too. 94 does have a different timing belt than a 90 but still works, you just need to use the water pump pulley, crank pulley and alternator off the 94. the timing belt is wider so the alternator sits a little farther out so use the alternator and pulleys off the 94. they don't seem to have the noise problem with belt as much as the older ones

OK thanks for the help.
Now I know it's safe for me to buy the parts car I'm looking at.

I have and drive a 1985 carbureted sprint with the 1.0 motor. I have a 1989 geo injected 1.0 bare block, can I rebuild the 89 block using new 1985 parts and swop to the 85 head????

No, Mark I engines were different. 89 and newer engines were the same with different accessories bolted on, but 85 0 88 was a different beast.
