Crx HF motor rebuild question (pistons)

I am in the process of rebuilding a spare d15b6 (HF motor) and I have ran into an issue with one of the cylinders having a slightly larger ridge than the other 3 cylinders (which are within spec).

The problem is that the d15b6 no longer has oversized pistons available :cry:

The rods/crank is different than all other USDM d-series motors (smaller/lighter).

The next closest motor (besides an EDM motor) is the 92-95 Civic Cx, which used the same pistons in 92, but 93-95 used pistons identical to 88-91 Crx Dx. The Cx head cast is the same as the Crx HF but has a different rocker assembly and camshaft.


Anybody know if the Crx Dx pistons will work on the Crx HF motor without causing any issues? Any other suggestions?
