Just purchased my first Honda, a 1985 Honda CRX Si. Super clean inside and out. 118k miles. Only problem is that the motor has a bad knock, I mean really bad. Haven't diagnosed it yet but also wondering if there is an equivalent motor from any other Hondas I can drop in. The motor I believe is a D15A3 1.5L.
I would like to keep it close to stock as possible. Thanks
