I know people have talked about building a motor using a 1.8 and 2.0 crank and rods. I have done a search but I guess I am not putting in the right words, I haven't found what I am looking for .
Can anyone hook me up with the right info on building one of these motors??

The easiest way is to use 2.0 crank and rods along with proper 2.0 pistons and cylinders. You can also use 96mm pistons on a 1.8 crank and rods, but you don't get quite 2 liters. The Cap'n

Look here.

A 1.7 is a 66mm crank with 90mm pistons.
A 1.8 is a 66mm crank with 93mm pistions.
A 2.0 is a 71mm crank with 94mm pistons.

All engine cases are the same basically which means you can use any combination of crank and pistons in them with the exception of the 1.7 heads which are only used with 90mm pistons. The 96mm pistons can be used on the 1.8 and 2.0 without machining, but you will need to machine the heads on a 1.7. So basically what the Cap'n said. Find a 71mm crank and 94mm or 96mm pistons and you'll have a 2.0L

a 1.9 is a 66mm crank (1.7or 1.8 ) with 96mm pistons.

Actually, 96mm pistons to fit a 66mm crank won't work with a 71mm crank. The pin heights are different to accommodate the differences in throw. The Cap'n

1.9 = short stroke hi revs, Fun motor
