one complication - your 85.5 block does not have a provision for the timing belt tensioner used on the 16v cars. you can modify the block to accept that tensioner though.

what ECU will you use?
I think the pistons are the same size, but will
double check.

Is the timing Belt tensioner absolutely necessary?
If so How dificult to modify the block?

For the ECU I was told a 85.5 or later would work fine and
Would eliminate the need for a hall sensor.
