How much is a honda b17 engine worth?
 

I have a well running honda b17a1 engine from an Acura integra GSR. Im wondering how much it is worth to sell? this engine is rare, please only answer if you know what you are talking about.Also it has ~90k on it

If it is in good condition, pressure test comes good on all four cylinders, and with an average mileage of 30,000 to 50,000 miles, you might be able to find someone to pick it up for around a grand, maybe a couple hundred more. Probably not that much, as people would rather get the H22 motor, or B18/ B16 build....but it might be possible. I would say anywhere between 700-1200 max.
