My Integra XSi

I have a JDM righthand drive 90 Honda Integra XSi with a pre-obd B16A. My car has a port and polish job on the head. the head has been milled .010 inches. My car also has a spoon clutch flywheel and gear set. I have Falken tires and Apex N1 coilovers on stock 15" wheels. So does anybody have a B20B or anything. I was ayso considering puting a ITR crank in there w/ ITR rods & ITR pistons, but not sure. just looking for advice.

The XSi is going to have a JDM B20B droped in and a LSD ayso, when the parts get here...

B18C5 = 81mm bore
B20B = 84mm bore

I received my B20 block, now I'm just waiting for the LSD, but first I need to replace my electrical system...
