Look what I bought! Dual Webers!
http://cgi.ebay.com/ebaymotors/ws/eB...5629&rd=1&rd=1
I'm just glad it went for under $500. The reserve was $400. I just need to scrape a little bit of money together so I'm not so screwed due to buying this. (shameless plug: https://www.rx7club.com/showthread.php?t=620907)
So the list of things to do when I get it are:
-Rebuild the Carbs (anyone know where to get a kit and a manual?)
-Recharge the K&N filters (they look like they're still pretty damn good)
-Wait until the weather gets nice to install and tune
-Oh and I need a new fuel pump
So who's jealous? Orrrr who's going to tell me I could've done better?

Call these guys up for the kits, its where I bought mine- http://www.piercemanifolds.com/
Here are pics of when I rebuilt mine, http://frosted7.com/katrina32.html, they may or may not help you out. Made such a huge difference after being rebuilt, and retuned in sync. You'll definately be happy with them! I'll be getting rid of mine this summer on ebay though, but if you need help or advice tuning, pm me.

You can count me as somewhat jealous. The dual weber setup is something I'd like to have. I bet it would really perk up my mildly ported 12A versus the stock nikki.
Getting the RE header in the deal is just too cool. I'd rather have that header than the RB one I recently scored for $100.

I think Trochoid is using one of the Dual Weber setups he has for his 1/2 Bridgeport. So these things must be pretty damn cool.
Hooray for American Rotary Tuning! Rotary Engineering.

Great grab! You'll like 'em I havent heard of people making as much power as you would with a side draft, but drive ability is supposed to be much better if you get it tuned right. Good grab you'll be happy with it.

tuning is the suck... you are going to a have to keep then in sink.. and every 1 knows carbs change with the weathers now you have 2 of them to keep up with..truning to keep them both tuned the same it will be a weekley thing for you to be messin with thos carbs...but the plus side is they look fan-damn-tab-u-less... and will make your car run perfect when tuned its lots of work but worth it gr8 buy

Yeah, the dual weber down draft setup is very dependable on the street, once it's tuned correctly. The side draft setups are better for the track though, where the RPM's are normally kept in a much higher range. They just lack the low-end of a nikki or dual weber progressive 2bbl.
Sterling has said repeatedly that the rotary needs a small primary/large secondary carb setup for best performance throughout the RPM range. Hard to beat the dual webers.
I dunno if Trochoid has one of these duallies or not. I know he was recently looking for one, though.

I bought 2 complete setups after looking for over 18 months. One for a 12A, the other for a 13B. I just about have one set up ready to install on the widebody, waiting for some warmer weather as all of my inside space is filled atm.
I did take one set apart for cleaning, being very careful to preserve the gaskets. They are much simpler inside than I expected. Tuning should be fun as I swapped the 13B carbs to the 12A mani and not a single jet or tube has an identification # on them.
I was watching that auction also and noticed that some parts for the linkage may be missing. If you need pics when you get your's, let me and I will take a few. The intake mani looks great after powdercoating it in a mettalic silver.
Hopefully these will solve my lack of size that I have with the Mikuni.

I also was watching. If i would have got my tax return back I would have bid on them. Instead my tax return is going twards new tie rods on the GS and maybe a MSD box.

I remember those when they first came out. Rotary Engineering claimed 152 hp with their exhaust system and the twin webbers.
Many years ago I walked by a set in the salvage yard laying in the dirt with the chrome breathers tops still attached.

Nice find. I just bought a dual weber setup myself... it was a little more expensive but it came with the rest of the car already attached
The drivability is great. Combined with the header it's almost like driving a stock car except it makes twice as much power. And, the 36DCD is just about the easiest carb there is to fiddle with. Supposedly they are a little more high maintenance but it's not hard at all.
Can't believe someone would throw away a perfectly good set of 36DCD. If nothing else the carbs themselves would fetch some money on eBay since you can't get them new any more and there are lots of cars still running them (stock on lots of european stuff in the 60s).

I'm kinda excited and giddy that my little silver fb will have the same carb setup as the famous black widebody.

Honestly, its not all that hard. I used a pair of narrow band a/f gauges, put a sensor in each pipe of the header, and that allowed me to get the a/f relatively close. The idle speed just takes a bit of tinkering and trying different combinations out with the timing. As far as them operating in sync mechanically, there was never a real problem.
