Ok, healthy street ported 12a do I go Webber or a modded nikki?
Both are in the 500 range.

Comments on these if you have one of these setups. Car will be doing some autocross racing and the often drive thru the city.
Full mindtrain exhaust, and coilovers.

 

Depends on what you are looking for, the different carbs will feel different. I could very well be wrong but I don't think a nikki can keep up with a streetport, though.

 

I've used both a 45 DCOE and a Nikki modded by Jeff20B. The Nikki didn't have all of Sterling's mods, though.

I had sort of a love/hate relationship with my Weber. They're so simple and yet so complex. They're extremely tunable, and make great power, but they do require a lot of tuning to get them right, which can get expensive if the settings are way off when you get it. Also, with a modded Nikki, you can use your current manifold, while you can't with a Weber. Overall, though, I think I'd take a 48 IDA over a Sterling.

 

I have a 47mm OER brand new for you manifold included $400 shipped let me know

Ask Jeezus, he'll vouch for me that it will be great setup for you.

 

Well based on the facts and of course my total bias, I say Sterling. If your mostly driving around city streets and some autocross your going to want something that can start from a stop easily, cruise at partial throttle gently without bucking or hesitation, but still give you a nice rush when you want it. For autocross your going to want the same thing, something that responds well at low, mid and high RPM. As those that have autocrossed know you don't really spend much time at the very top of the power band, which is where a 2Bbl carb works best. You need something that works all around. The Sterling is a good choice. It is also easily tuned. Pop the top and change your jets.

 

yes the highly modded sterling carb can.

 

weber and you know where to get it















*primaflow*

 

You're wrong.

 

please define "highly modded"

 

Bored and reshaped venturi's to increase flow from 313CFM to 465CFM
Drilled and tapped emulsion tubes to accept holley 10/32" air bleeds
Minimized linkage
Mechanical secondaries with the ability to easily switch back to vacuum operation
They're real purty when painted

That's pretty modified I think

Although technically a Sterling isn't modified, the Nikki is modified to become a Sterling.

 

48 IDA FTW!!!!! ...and you'll never look back.

 

Mmmmm OREO carbsssss

 

Yes sir!!! They are the goodness. Just sold the OER 47 I had though, all gone

 

 

what he said....the IDA on a 12A SP leaves the stock tacho in the dust....

 

I love my Sterling. Very happy with the throttle response, and I've never lost a race due to a lack of horsepower.

 

the other day i saw wacky take apart a nikki and all i can say is the weber is a lot easier to do so....

 

I have a 48 Dell but it is for my 77 Repu once the motor is done.
Besides I need low end power as well, so I think the sterling is the best bet.

 

Man your setup is almost like mine. I saw the video and it never seemed like you starved for fuel in those hard turns. I guess I need to got his route.

 

You know, I think one of the best testaments for the Sterling is that video of mine when I'm racing in the pouring rain. Driving at the edge of traction, you've got to have good throttle control. For the first half of the day (before it stopped raining) I had the fastest time, even against the Miatas and Subies, plus an Evo. Racing on nearly bald 50 dollar Sumitomos, no less. Now, the suspension helped me get around the course fast and in a stable manner, but the carb is what kept me from fng it all up and ending up **** backwards.

A lighweight rear driver taking on the turbo all wheelers says a lot. Definitely was my all time favorite day of racing. Power is nothing without control.

Now, to be fair and upfront in all of this, I will state for the record that I have no experience with any other type of carb (relating to rotaries, that is). I started with a buggered Nikki, rebuilt that, later modified it (and it is now in the hands of Man in Black who loves it to death), then moved up to an early Sterling that I bought used.

The Sterling has fulfilled all of my needs, and I haven't even tuned the damn thing yet. lol. I'm sure there's even more power to be had once I get around to doing the tuning, but what the hell, I've got all I need right now.

Besides, 60 hours a week of work + wife+ kid+ kid+ kid = not a whole hell of a lot of time/money left over. And I wouldn't change a thing...

But in all seriousness, Sterling is right up there with Respeed in my book. Even though I bought the carb used from someone else, he never hesitated to give me great customer service. He stands behind his product, and his product has held up fine through all that I've put it through. If people are good at what they do, and they treat me right, then I will not hesitate to pass the word along. But if they don't, then look out. But that's a whole other thread there, and don't even get me started on the damn decal that Racing Beat puts on their swaybars!!! How stoned do you have to be to put a damn decal on upside down?!

 

Thanks man. But I actually have had an issue with bog on hard left handers. Suffered through two race days banging my head against a wall. I believe that was the first time I contacted Sterling about the carb, and after a few questions to help him understand the situation, he advised me to try reducing the fuel pressure a bit. Worked like a charm. Later he sent me full instructions on how to tune the carb, along with logging sheets and all kinds of other stuff I really should put to use one of these days. Hell, maybe I oughta just drive over there for a couple of days and sleep on his couch while he does it for me. lol Do you think he'd take payment in Heinies?

 

My door is always open. (Especially when there's beer involved!)

 

Yep, I think I will get the sterling nikki for my 79 as well as get another carb just the basic rebuild to have on the shelf in case I or someone needs to get up and running. The basic plain no cleaning charge for the basic rebuild is better than me trying to figure it out. And with having more than one rotary, it might come in handy. Just wish the 8 week wait was closer.

Is your motor ported at all? What fuel pressure are you running? What is your timing set at?
Hit me up sometime, maybe we can talk over the phone.


I understand that. I work for the fire department, volunteer at another one, have a 5y/o, a 8 month old, have 9 other rotaries, and still in school. Then to top that off Charles and I try to help the locals and build them motors and work on their 7's as well. That leave no time for the wife or house, so it seems sometimes.

 

No, the motor has stock ports (necessary to race in CSP). I don't recall the fuel pressure I'm currently running because I recently made a reduction in pressure, which ended up improving the top end hp. I'll take a look when I get time. Timing is stock...
