@Lurch - thanks for the info and tips. I'll probably have to wait until next week. Flying to San Francisco this week. So I'm going to leave the motor outside of the garage so I can park the RX-7 back in there and under cover.
@John - The g/f was almost asleep when I asked her to come out and handle the 'dirty' bonnet. She wasn't too impressed but she understands my enthusiasm. I too hope it doesn't waiver, but I have to say so far I'm really enjoying it. I'm not rushing things (for the most part) which helps a lot, having said that I'm trying to chip away at 1 job at a time to keep me motivated. I'm looking forward to tearing down this motor. I'm also thinking about using the LD28 crank, L14 rods and triple Mikuni's on this motor. I'm just not sure how much coin I want to invest in the engine head work yet. It's got an E31 head on it right, mounted on an F54 block. Will see if any work was done to it.
If I can find a P90 head I might start with that instead.
I'm sure I'll need your advice when it comes time to do the body work, I'm a total newbie. But willing to give it a go.
@Peter - Don't suppose anyone has a photo of what these tubes and bolts look like? I'm sure I'll figure it out. Thanks for the offer on the rattle gun compressor etc.. I have been thinking of investing in an air compressor and rattle gun anyway to remove the diff / rear suspension assembly etc.. I just don't know apart from CFM what to look for in an air compressor. You can get the cheap ones but something that will work for laying down primer and also for painting small things like badges etc..
@Dimitri - yeah looks like a 280zx engine block was fitted to it. Lindsay at Zshop said it was also fitted with a FS5C71C gearbox, I forget which gear box that is though? 240z / 260z or 280zx?
Rattle gun would be an awesome bit of kit to have, the amount of times I've had to use a long breaker bar to undo bolts on cars. Plus an air compressor will be helpful for painting, I'm not a huge fan of rattle cans.
