Don't start a debate or I'll have to invite you to race lol. Scratch the fuel efficiency comment. I could watch the needle go down under full throttle in my old 12a but if you guys are saying your getting in the 20 mpgs then heck, your doing quite well.

20 MPG on a modded NA rotary.
I'll take that bet ALL day long and twice on sundays

I do all my own welding/ machining and is something I wanted to learn while taking the project on. Drop a stock one in and you almost have double the hp and fuel efficiency for the cost of a 12a gasket kit and a bit of time. Seems like everyone who wants one still has a boner for a shift buzzer.lol only kidding but my **** are you ever ignorant. It's down to personal preference like I said, didn't feel like each persons preference should have been debateable.

I'd rather not have ANY point of reference with that crowd. Not saying you are one, but you cannot deny the following those cars/engines have.
And I didnt knock the swap, you just called me ignorant because I hit a soft spot with the boy racer comment.
I'd ask you to recant it, but I really dont care. You will spend more money swapping to a different engine entirely and hacking up a perfectly good car than you would rebuilding your rotary. Plus, you would probably like it better than a bland datsun 6 banger IMO.

maybe at an optimal rpm on the highway, letting off on the exits etc you might do it. I alot of it has to do with how you drive the car.
hell I can get 4mpg better than my wife driving the same car!
but to realistically say average city/highway and not babying it or ******* it......getting 20mpg . i'd happy lose that bet. even the brand new ones can't say that. they get like 16-17 mpg. why do you think the rotary is dying?

Secondly, were talking about the 12A. They got better MPG's than the most recent renesis back in 1982. And that was while they were choked with 3 cats, and a myriad of emissions equipment.
The 12A is a good, and overlooked engine for daily use and reliable performance. You just cant think you're the stig and floor it everywhere. On my last tank of gas, I cruised at around 90 mph for *hours* and had my foot deep into my secondaries screaming through lanes and even a few times breaking 120 mph on the empty freeway. Still got 17 MPG on that tank. Lol.
If you drive with some sense, and stay within in the speed limit and properly tune your **** 20 mpg average is easy. I have been pushing my own farther and farther on each tank with intelligent jetting choices...

Firstly, I run 4 bbl's that allow me to push my AFR's far beyond what even fuel injection can muster and still run properly on my primaries for cruising, which is most of my driving. The benefit of the 4 bbl is having a second half of the carb jetted for power and the rich fuel mix that rotaries need to make peak power. So, its like having 2 different carbs. One for sipping gas, the other for going like stink. Its surprisingly efficient.

my SA, which was completely stock, got 23mpg round trip on the ~1000mile sevenstock journey, 2 years running.

I have already gotten 32 MPG highway with a holley-style carb on an original 12A. Notice I said "consistent" 24 MPG. Implying both city driving, highway, and spirited runs on the same tank.
Methinks the carb is fine.
ALSO, if you are running 465-500 CFM carbies on stockport 12A's you get an easy 24 highway just by running them stoic@55 mph. You can push it past stoic with a 4bbl (NA) and get some extra MPG's...

How is stating a fact being ignorant? Anything nissan that begins with "RBxxxx" is boy racer territory and $$$ for speed parts. I can't tell you how many nerds with Nissan Skylines I talk to on a daily basis that dont know dick about their own car. They just spend 1400 dollars on cams here, 900 on a header there, few thousand for stand-alones, and the obligatory 3k bucks for wheels and low profile tires for that "stance". They just know the engine name, and that it is a wet dream for teenage boys who think Skyline>All

And I didnt knock the swap, you just called me ignorant because I hit a soft spot with the boy racer comment.
I'd ask you to recant it, but I really dont care. You will spend more money swapping to a different engine entirely and hacking up a perfectly good car than you would rebuilding your rotary. Plus, you would probably like it better than a bland datsun 6 banger IMO.

But hey, what do I know? Some guy called me ugly on the internet! As for the bigger man argument, try harder.

I think we all need to stop and calm down.
Why stick with a 12A? You can work out fuel mileage and decent reliable hp. Thats an upside to these little motors.
Rb20 i know nothing of it and i feel like maybe ppl should not talk about pistons is it a good engine sure but not here.
Why should anyone spend money on a 12A well as as far i have seen and experienced alittle more reliable then 13Bs sometimes you can workout quite some power with just the carb and some exhaust mods. Do they have tons of HPs no way but thats the fun of it making slighty faster with what you've got.
Hell do a port job to maximize power if you do it just right you will be smooth going for days if your looking at something like an aggresive bridgeport to a simple street port. Why not spend money on a 12A?
Buy arguing guys forget it wether he would rather have a 12a or a bugatti engine is not up to us but us just being able to suggest why he should spend on one. If there will be arguments its probably better to stop posting in the thread.
I like seeing useful post that i can learn from not people bashing on each others age or intelligence.
So lets all hold hands or something make up like the french do with a kiss on the cheek or something like that.

You could do what i just did. I built a 13b using turbo2 irons (which are strong and 4 port) and s5 n/a rotors. I kept it stockport, however the ports are larger than n/a. I just wanted a strong, reliable, peppy engine. Oh then i powder coated it chrome.
Where people screw up longevity is the pursuit for more and more power. The turbo.

Although I have never done a turbo, even a highly modified 13b can be fickle.
thats why I chose the boinger route. when you want 400hp your pushing your luck from a reliability standpoint
and even pulling 225hp out of an NA 13b is gonna be an engine that likes to scream and does not have much bottom end. i.e. streetability
to each his own. I would rather race a rotary though. Love those high rpms. my last one would shoot flames out the back when running her hard. only know because someone told me one night when they were behind me. very kewl
