Default My new/old baby.

I just wanted to say hi and show you my 1st gen acquisition. I also have a FD3S 13B REW that I've shoehorned (successfully) onto a miata, so I'm no stranger to the rotary.
I'm taking the FB apart and refreshing everything. Engine will be re built by me. I'll have questions on seals, porting, etc. I hope I can ask you guys a lot of questions.
My thanks to the admin and members that keep this list going.

HI t_g_farrell.

Interior is very nice and complete. I'd post photos but the car is being worked on. A couple of the guys removing the steering box and column.
Car was always garaged. No stains, scratches or any blemish that I could see.

^Now that's something I'd like to learn more about - always wanted to stick a 13B into a Miata. Do you have this project posted up on a Miata forum somewhere?

Since I'm going to have a spare series 5 13BT to play with soon, the thoughts of picking up an NA/NB Miata as a project car to put it in it has been rattling around in my brain lately!

Hi Pete_89T2.
Actually it wasn't easy. Built a jig to keep everything straight. Cut the Miata to accept the FD front end while still maintaining the OEM Miata fenders. I used almost everything from the RX7, engine, drivetrain, suspension, electricals, even the instrument cluster which I had to mate with the Miata dash. Did all the CF work myself even the CF Sparco CF copies. I have a deal with a local car magazine so I can't show my build thread, 50 or so pages with photos and written logs. Wish I could. But you may see these photos:

Those are old italian ferrari wheels right? Looks a lot like the mazda limited
editions, so should look right on the car. Good find.

I have a thread about restoring waffle wheels that should apply to those as
well. I'll see if I can dig it up.

Yup! Those are Campangolos in magnesium and very light. Hard to find here. I was lucky. 13s by 6.
Looking fwd to your repair thread. Thanks!

Ahhh. On the miata. It works pretty good. I even tweaked the ratio to about 1:1.25 or somewhere there. The strut travels a bit more than the suspension travel.

Just asking it it's ok to continue the teardown/rebuild of my FB on this thread? Or should I make a totally new thread?

I was amazed at how heavy the doors and hood weighed so I made molds. And then proceeded to make the parts in carbon fiber.

Here's a finished inner door with the steel window frame being test fit. Found the door to be lighter than the frame with the skin installed. How heavy is this car? Because I'm sure I'll lose a lot of pounds/kilos.
