Hi Guys, this time I have a question about a stroker kit we are going to use on a B18B1 engine, all motor, all standard

First question, a guy gave us a stroker crank, Im not pretty sure if it is 90mm or 95mm, I know is a 2000cc stroker kit, that is 90mm or 95mm?

Second question, we are thinking if it is a 90mm stroker crank, we can use the LS rods, with PR3 pistons, which i used the B series compression calculator and it gave me a compression of 12.16:1

If it is a 95mm stroker crank, we think we can use the B16 rods with PR3 pistons and the calculator gave me a compression ratio of 12.09:1

We are going to send the crank for checking to a machine shop here in Costa Rica...

Now, those setups sounds fine? I'm not pretty sure if that is going to work, it sounds logic, but maybe somebody has more experience with that.
This is a proyect, we are doing this in my house, so I want to learn...
Thanks for the help guys...
