I am looking for a 89-91 civic Si, and I need to know how to tell a real Si from a swaped dx. My Dads 88 CRX Si's vin starts with a "J" so it was built in Japan. If you can help please post.

Have you tried looking at a Haynes or Chilton manual? The Haynes manual breaks down the VIN number, so you might find the info you're looking for there.

yo cant tell if the si has been swapped in a dx or dx in the si?

advance auto has a manual that breaks down all the numbers and letters in the VIN#. Just make sure u ask someone that knows whats going on to find the book for ya.

i thought there was an interior difference, but i think thats the only way to tell.....but you can also look for a vtec wire up thats not factory, crx si's came with the 1.6 sohc vtec right?.......and the dx's had the 1.5 non vtec, so i guess you can look for a wiring harness that looks messed with.......

Si's have a better interior and a sunroof.

Pm me the Vin Number and I will run it for you and let you now. I am a parts manager at a Honda dealership.

civic's came with a single over head cam 1.6....non vtec... the si has a power sunroof that slides between the roof and headliner, not on top like a CRX.
