NA 20B build
I've been accumulating parts for my next build and figured this was the perfect place to document it.
Car is a Silver 93 touring with around 35K miles. I bought the car to part out, but never got rid of the roller. Its fairly stock except for a set of stance coilovers, a 99? spec steering wheel, rear seats. Plans are for a fairly simple and relatively cheap build.
-Mounting kit from Defined should be on the way soon
-C series 20B with NA 2nd gen rotors
-PFS broke down the block and is going to do a soft seal rebuild and porting. Currently deciding if I should keep its half bridge, go with a full bridge, or get new irons and street port them
-55mm Kinsler ITBs
-A used header that I picked up on here
-TEC 3r
-A massive Fluidyne radiator with an identical size oil cooler sandwiched between the radiator and fans
-Fikse FM10s or Mach 5s
-Racing beat dual with as many resonators/ xr1s I can cram under the car.
-A fresh coat of silver followed by a 3M matte silver wrap, or sprayed in frost silver like the M series
-A set of Recaros

I also heard good news from Sikky Motorsoprts this past week. They are finalizing thier mounting kit that useses the factory subframe (LSx RX7). I'll post the build pics from my LS1 RX7 build in here when I find my old hard drive. I was gettign a little worried I might beat JimLab for the longest uncompleted LSx RX7 build...

Makes sence to wrap the car, although I'm not sure I'd want a giant sticker...
RXtacy do you have a thread with more pics. I'd love to see them.
Small update:

The ITBs are 55mm. I'm going to have to trim the stacks to fit the hood, so I have no idea what length it will be in the end. I'm sure Logan has his reasons for his intake lengths. I'm just working with what I have. I may get Logan to build me one, If I put down disappointing numbers (<300rwhp).
I have no idea when Ray can get it in the shop. If he can't get it done this summer, I'll take a few weeks off bolt it together in June. He hasn't rebuilt the motor, but I emailed him a few ideas of what I was thinking. He knows I just want a fun street car that I can take to the track a few times a year; I'll trust his judgement on what I need.
-Clean up existing porting, keeping the half bridge.
-Dynamically balanced rotating assembly.
-Lapping and re-nitrating the irons, if needed.
-Sending out all three housings to be resurfaced, or just replacing the one questionable one.
-Clean up/ enlarge oil passages in the irons. Tap the irons for external oil feeds.
-Clean up/ enlarge coolant passages in the housings and irons.
-Replace the 20B exhaust sleeves with FD exhaust sleeves or Rotary Works Titanium sleeves .
Am I missing anything?

I'm looking forward to the event, and would gladly take you up on your offer. I sold my last RX7 to PFS back in 98, so its been around 14 years since I've driven a rotary powered RX7.
I've got to get this thing running. Ive got an itch to go test drive the new Cayman. I'm sure the RX7 will relive it, I'm just hoping i don't cave first.
Are you still running three ID 1000cc injectors? Has that proven to be sufficient?

Nothing much to report but a little progress:
Dropped off three spare 20b rotor housings, Ray will pick the best of the six for the build.
Picked up the rotating assembly, which will be sent out to be balanced.
Anybody know where I can get a thick 20b IM to block flange cut up? I'm thinking of buying a welder and trying to fab a LIM.

Not sure if I'll actually have time to build this car or have PFS do the whole thing. At this point I'm just taking it one step at a time.
I'm a huge fan of the color you chose. Can't wait to see it color sanded and buffed.
