Okay I didnt know if I should post this here or in Tech but since Im looking to build a hybrid figured Id put it here. Im a noob at building engines so Im not doing it just trying to learn some things and soak up info.

To start I need info on the K23A1:
Whats the rod length and width?... I know the stroke is 99mm
Whats the height of the pistons?...I know they ar 86mm bore
are the rods and pistons really forged or is that yet to be provin?....not much info found
can the k23a1 crank b put into an F20B block (DOHC)?
can a K20A head be placed onto an F20B block?

Please give real info not just opinions, I know there are tons of reliable builders on HT so Im hoping they give some help.
