Yes, build date of 88 came with the V6 in the 2nd gen body style. Owned a 4runner (1st gen) that had one in it, I'll never own a 3.0 again! But if you want to know then there should be a data plate on the firewall, fender or hood. Unless its been removed/swapped/painted... Or the VIN code will tell you with a little research.
