Sup HT, I have a couple B20 engine blocks, one is cracked at the oil pres sensor but has good internals so I want to swap those internals into my B20B4 for higher compression. I'm going for a NA B20v but eventually I'd like to go for low boost. I'm running a tapped GSR head with type r valve springs / retainers, GSR cams and I'm going to button up the bottom end with ARP rod bolts, head studs and a high pres oil pump. I'm looking for any pointers I could use along the way. Also, the parts (pistons, rods, crank) from my Z2 should be a direct fit into the B4 correct?

Thanks guys and happy new year!

The only difference internally between the B4 and the Z2 is the pistons they used. Aside from having a different oil pump (for the crank sensor) and a different intake manifold, everything else is identical.
