^^Absolutely. And 13B is 1.3l 2 rotor and 20b is 2.0l 3 rotor engine! I had an 89 FC RX7 convertible. I loved that thing. I wish we had never gotten rid of it. I sell cars so I get to experience quite a few of them. I really had no idea until I got one in that the Mazda Millenia S was supercharged. I guess the S should have given it away! lol. It threw me off even more when I saw "Miller Cycle Engine" on the valve cover? Do you know the story behind that? Is Miller Cycle Engine a tuner that they contracted to build that motor? I was really surprised by it. I have learned quite a bit in the last year and a half that I have had my car. I have not really ever been into imports but decided one day that I wanted an Si and got me one. I was a blank slate when it came to knowing about Honda's. I am still learning something new all the time. Asking questions and doing your own research will usually pay off with knowledge when you are really interested in learning. Vteckidd was probably the most helpful in teaching me most of what I know. I probably annoyed the shit out of him (still do? ) when we were planning my build. 13 days until Turner field, can't wait.
