Engine size determined by engine family

I have some problems with fitting engines from a family into cars. I don't know if it's a problem or not, but the sizes from the engine seem to be determined by the family rather than the actual engine. The minimal bore and stroke engine with the same parts has the same size as the max bore and stroke of the family. Is this intentional or some oversight or bug? I could not fit a 1.0L I4 with the same bore and stroke into the smallest car after I made the family with a max of 1.5L, which was first limited to 1.0L

That's intentional. Real life example: my Ford Modular V8... doesn't matter whether I bore the engine .030", and/or stroke it to 5.0-liters, externally it's still the same size.

Yeah, a "family" is not supposed to be just for sorting reasons, that might be coming later, but families are the base engine for all of the models. This means that producing different models would be cheaper than running two different production lines for both engines, reducing cost. It wouldn't really be building another model based of the engine if almost all of the parts are changed on it

Will there be any point having two engines (eg 4 and 6 cylinder) share the same bore and stroke, so they could share the same pistons? Or is that too granular?
I know I've heard that some v8s are two i4s 'bolted together'. I know it is not that simple, but there would be cost savings if the same piston and connecting rods were shared amongst multiple engines.
It would be kind of cool to say when I do my next set of reviews "This is the high performance version of the Civic; uprated internals and the same pistons and connecting rods as those in the new NSX". (but replace Civic and NSX with something from the forum member's lineup)

As far as I know creating V8 and Line 4 are not that kind. Its not possible to create V8 from 2 Line 4 engines. For example how that is created look on youtube for creation of V12 Ferrari engine. You will see that its not that easy.

The block and crankshafts are not, but pistons, conrods, and heads can be.
