I don't know the answer to your specific question, but hopefully one of the others here does. Just chiming in because with the help of this forum (lots of info upon searching) I changed my own timing belt and it seems to be running fine - I didn't even set the timing as it seemed to be right on - something I'd like to get to though. I hope you are not off by a tooth, that would be a drag - you should have seen the marks on the case though the manual clearly points them out - I assume you are referring to the timing belt marks inside the cover on the pulleys(?).

Good luck! Nice to see people trying this.
