sorry to hear about your cars engine. i think your mistake was not tellign HPR about the previous work, otherwise none of this woudl have happened.
still, no point crying over spilled milk. i look forward to your next project. my advise woudl be to go for a B16, B18 or K20 if possible or worst case, consult HPR and see if they can fix your current block, or even just swap over another D16.
