Best bet would be to try find the VIN number for the original car it came from and then use these 2 websites to determine what the part number is. Easy way to find VIN numbers is to look on ebay, as some sellers list the VIN number. So look for auto Integra GSi.. or what ever car your motor came from.

example ebay search:
http://www.ebay.com.au/itm/Honda-Int...#ht_500wt_1389

VIN number: JHMDC43500S00750, engine number: B18B21000749

and another one http://www.ebay.com.au/itm/1997-Hond...ht_2104wt_1373


and then search the VIN number on these two sites:
