Thank you all for taking your interest to reply to my post. So i've ran into a OBD2 B18c5 complete bottom block for sale... this guy claims that he actually purchased it from a dealer through an "insider" and is wrapped up and has never been used before... do those even exist?

Anyways, i'll be examining it tomorrow to see how legit this block of metal really is (any advice is appreciated in looking for the right things).

If i were to purchase this motor, what will i need to replace or be aware of when installing it into my 2000 gsr. I'm going to machine and rebuild my original gsr head and attach it to this type R block with my original gsr tranny. Any advice or recommendations? Is it possible to convert my gsr head into a type R?

Thanks!
