I just ordered a b16 starter (del sol vtec) and when it came in I found that the bezel gear didn't stick out as far as the starter from the b16a. It looked like it was about 1/4" shorter. Also, the positive lead connection is on the end, not out of the top. That shouldn't matter though. I didn't install it because I wasn't sure if it would shoot out far enough to engage the flywheel.

When they looked up the Integra starters, the only motor options on the U.S. models was 1.7 and 1.8, not the 1.6. They ARE b-series though.

Aren't the 99-00 Si's a d-series?
