Default H22A vs. H23A vs. H23A DOHC VTEC Prelude Crankshaft

I've done numerous searches on this.

It seems as though the H22A Crankshaft is superior to the H23A (Non-VTEC). The counterweights are bigger, and is simply better balanced.

My question is... does anyone know anything about the H23A DOHC VTEC Crankshaft?

Is it an H23A crankshaft with H22A like counterweights? Or is it the same H23A (non-VTEC) crankshaft.

Anyone have any pictures?

To my knowledge there is no difference in the crankshaft of an H23a1 and the H23a(VTEC)... However I haven't even found that much info on the actual H23 VTEC and I wonder if Honda made any updates to the H23 block for the H23a VTEC since it was released in a 98+ Accord wagon(i.e. ya think Honda changed the H23 to 55mm mains like all the other 98+ blocks???)...

if it is true that the accord wagon that had the h23vtec in it was 98+ (i don't know my JDM ****) then yes honda almost deffinatly put 55mm mains in it.

that would be sick if that h23 block was closed deck, or i wonder... so many unanswered questions..
