B18c block bored .40 over?

[B18c_eg_hatch]

Hey people I just came across a b18c1 block with 40 over ITR pistons (made by top-line) There on gsr rods and I think a LS crank, but Im not 100% on that...It looks more like a type r crank...
The walls look great are are not thin at all, but what I was wanting to know is what (mm bore size) will that make the block have and what displacement


Thanks

if it has gsr rods it should have a gsr crank & vise versa....and i would not buy anything over 81.5 or.020
