Hello!
well I think the only D series DOHC is ZC..which came in Integra...but thats NON VTEC engine...
This looks Early Model B16A to me.....!and yeah its B16A making around 160ps @7600rpms and 15.5kgm of torque @7000rpms....!
These engines are introduced in mid 89's in JDM DA6/DA8 Honda Integra RSi/XSi.......!
B16A also have the pride that its the first engine to use the VTEC mechanism....!
Be check it before buying....these are high revving motors so check for any sound and weak rings symptons before buying....!
Regard
