Yeah, I've read and heard how expensive rotaries can get. It's the main reason I've never gone near buying one.
Here's the scoop, sorry for the rant beforehand. I work 12 hour shifts as a network tech and the only reason I work those hours is so I can afford to pay for my expensive hobby, cars. I love them and everything about them. My plan is to have a solid daily driver (My STi) and a great weekend car (rx3 / 240z), not something I push to 9k rpm's all the time just something I can build up and be proud of. Not only to enjoy, but to hopefully pass it on to later generations as well. I know that rotaries are pretty pricey and they need a lot of care but I am willing to spend the time and effort to keep a classic car like this going. I also have an ex-co-worker whom I still keep in touch with very much that owns 4 RX7's, two of them are doner cars. So I've spoken to him about it and it seems like he's willing to help me in my troubles.
More pics of an SP would be fantastic, I absolutely love the way they look. I love the big front air dam. Although, I'm not sure where to buy one other than Yahoo Japan so I was thinking of making a template out of wood then molding a large piece of sheet metal to the wood.
Yeah, I would buy that 13b if I need to get my hands on one, they sound like they're the best choice. Perhaps second to yetterben's suggestion of a 20b. Unless someone knows if I can drop an engine little easier to take care of that isn't rotary? I was thinking an SR20 since they're cheap and readily available. i'm not looking to restore this thing to it's original state, I kind of want something different. Which is why i've come here! Haha.
Thanks guys for all the helpful information.
