it's never been on a car. I took it out of the box to look at it when I first got it, and now to take the pictures. there are no gaskets with it, I don't think you NEED new ones, although it's probably not a bad idea to replace them.
I'm selling it for a couple of reasons:
1. trying to buy a house
2. want to see if I can run a 13.3 as my car sits
3. it's a full days worth of work to put it on
4. it makes the turbo spool at lower rpm, which is cool, but it means probably slightly worse gas mileage.
