I have an 89 crx si. I was told by the previous owner he swappd the d16a6 for a low mileage d16a6. Which runs fine. I want to order a new lightweight flywheel, but, i don't know what year to order due to the"swapped" engine and i don't know what donor car it came from. Alot of the companies want to know if its an 88-89 or a 90-91.

Anyways to tell?
