TD-84u and TD87u are different in terms of VTEC and NON-VTEC applications.TDxx model #s are assigned to almost all Honda OBD1 and OBDII engines, regardless of brand. As long as its OBDII (you can tell because it will actually plug in to your harness) I haven’t found a difference between an Integra VTEC and non VTEC distributor and have successfully interchanged them.
P.S. Spec R is one of the most helpful people Ive ever known - its cool to see you still helping and replying!
