Well I did not find anything in search,
SO are the 1.5 and 1.6 cranks and rods swap-able.????

Re: Crankshaft swap
my recollection is that they are not and the stroke on the 1.6 is longer than the 1.5 (thus more torque and displacement).
so crank must be different, would assume rods too. I think the pistons are the same diameter but not 100% sure on that.

Re: Crankshaft swap
Right, the bore is the same but the stroke is longer on the 1.6.
So a 1.6 rods and crank can be swapped into a 1.5 block,
it will hit the 1.5 intermediate shaft near the gear.
I haven't done it but others have put the 1.5 guts in the 1.6.

Re: Crankshaft swap
Yes, the parts are all 'swappable'. Obviously the crank-rods-pistons need to match specs, either all for 1.5L or all for 1.6L. To build a 1.6 in a 1.5 block (many would ask "WHY?"), you'll need to do some really minor grinding in a few spots on the block to give clearance for the crank & rods to swing around. The locations are obvious if you lay the 1.6crank & rods in the main saddle & move it around by hand. IIRC the most grinding was needed on the web that mounts the oil pump, and even that wasn't a great deal.
The 1.5 blocks (and maybe the early 1.6 blocks that had 11mm head bolts?) do not have the deeper threads for the head bolts, so using 11mm studs instead of 11mm bolts is common advice, for longevity.
Be sure to measure piston projection & select the right head gasket. Best wishes with your 'hybrid'.
