Hello to all. I have a wonderful 1984 533i that I have slowly improved over the years, and now I would like to try to beef it up a bit. I would swear that somewhere in one of the boxes in my garage, there is a Roundel from, I believe, the late 1980s or early 1990s, that had an article about one guy who made some modifications to his 533i to improve engine performance and output (and maybe handling). But I can't find it. If anyone can ID the Roundel edition, I understand the Foundation can get me a copy of the article. Or if you have a copy of that Roundel, please email me at firstname.lastname@example.org and I'll be happy to pay for a fax or a copy or whatever. Also, if you don't know of that Roundel article but have any other articles specifically about improving the output of that era 533, I'd love to hear from you. Thanks very much.
