what kinda adapter are you trying to make. i'm making adapters for the 1.6 motor to the 1.3 tranny.
the adapter should be the same as the this for the 1.6 trany just flip the counter sunk holes and mount to the engine instead of the tranny and use the 1.3 flywheel and you could use the stock 1.3 starter
because it's for the 1.6 motor to the 1.3 tranny i dont see why you cant do the reverse but remember the tranny is heaver less the flywheel weight and you will have to change the r/p
i have a guy who did the 1.6 16v and the auto tranny in a stock zuk and he said it sux he has stock 3.73 and he said it's about the same as the 1.3 with a grs1 with his 31's. the autos gears are the prob. also you have to shorten the shaft to the t/case and you should have it rebalanced if you are going to drive it on the street. i will post a copy of the plate i'm making. it is my own design NO COPIES OF ANY OTHER VENDORS but i paid someone to draw it in auto cad because it was the only way to have it laser cut. mine is wider all around for strenght and i stamp it on the drivers side
the first one is the plate i have been selling and the second one is the first one i made out of aluminum and i currently run this in mine and it has been TELLICO and ZUKI MELT 2002 TESTED and it has had a crash test. i was doing 45mph and rearended by some one doing 70 to 85 mph and it cracked my fylwheel and the adapter plate was fine
note *******
after looking at the pictures it looks like the starter will be the prob. it bolts thru the plate to the tranny. the 1.6 tranny is wider i guess you could mount the plate to the engine and then the flywheel and then tap and thread the plate to bolt the starter to the plate this should fix the prob. because the 1.6 starter area will be way off
