It's highly unlikely that you found an '89 with a B-series engine swap. All 86-89 Integras used a DOHC D16A1, a US derivative of the popular ZC engine.
The B18A1 wasn't introduced until the '90 model year for all RS, LS, and GS trims.
There are three different "LS" engines. Odds are you have the wrong one.
