thats what you need Miller! it's gonna be the JAM!


edit: almost forgot, it's only 750 cfm. and ifyou need even less, which you won't then you can get their reducers which bring it down to 450cfm i think. and this kit is made by Auto-Nomics. bruce johnson has been working with me, a very very helpful guy there.

Yeah, I forget who it was, elsyian, maybe, that told me about Auto-nomics.
About $400 for everything, IIRC.. Includes the rail, IAC, and TPS.. Should be able to get 4 injectors to go with from ebay for $125 or so. An intake mani for $150-200.. A real good deal for a FI intake setup. I emailed Bruce awhile back too, he seems real helpful.

for the short time i had my DCOE, the power delivery was great. no delay when you mash it..and lots of power starting at 3krpm, peaking around 6k.

driveability was ok, except for high rpm on the idle circuit(stutter) but wasn't a nussance. not having a choke worked out ok even on my tired motor. 2 pumps of the gas pedal and it started right up.

I say Dellorto... only because so far it was by far the least headaches out of EVERY set-up I've been through... and it pulled deep into 8-10K rpm range with no bogging or stutter.

i don't get what the big deal is w/ the whole "modified nikki", really. i've had a modified rx-2 nikki and it was OK. but driving around w/ a weber and mikuni.... those were much better.

if you're going to spend in the cool hundreds, might as well get a weber downdraft or mikuni. more peformance for almost the same buck.

but at the end of the day..........everyone will say............ taste.......... then sure, taste it is

i'm not hating on nikkis. i have couple laying around here.. for display purposes only.. paperweights, door jammers, room display

sure it does. we call it....... "more impressive on paper than performance"

turboIIguy is right. a mikuni flows better than a 48.it's been flowbenched tested.

i wish i have the papers showing it, but if you do your search or ask around, the 'experienced' ones too, will agree.

Love my set of R.E. dual weber 36 dcd's I just got. Decent low end but she pull's like hell from 4 into 8 grandand some change with no power loss probly go further just havn't pushed her, also there's suposed to be a 12a to 13b adapter plate that allow's you to switch from one to the other. I think they rock course I haven't tried any of the other set up's. Definatly kik's the hell outa my stock nikki. Well that's my 2 pennies worth.

Try both and then make your comment. They are slightly different in design.
Ford makes a V8 mustang and Nissan makes a V6 350Z......So why is it that the 350Z can whoop the butt off a Mustang???
Just because more people like it, and its bigger, doesn't mean its better.
I know a lot of old school guys out this way that would much rather get a mikuni if they had to go with a sidedraft.
But like I said.....Drive on them both before you comment on one....

Lo Duck, you haven't run one of MY modded Nikkis.
It's not everyone else's fault you don't know wtf yer doin'!
By all means, send some of those "paper wieghts" & "door stoppers" my way.

As for the comment regarding the idea that a smaller carb cannot outperform a larger one, well that's just another example of the bullshit in these kinds of threads where too much opinion is based on either childish "me likey da bling-bling" or silly-*** "bigger is better", and not science.
Physics determines how well a carb performs, not it's bore size or how shiney it is.

i have driven both and i didnt notice a "whooping" difference. i actually thought the dell made a little more power. just defending my dell from your "whooping" exageration. perhaps the mikuni is slightly faster, i dont know, would have to see dyno charts to confirm so there is no point arguing. you like mikuni's and i like dell's.

Thing is Kev, if you don't love the smell of gasoline or don'y wanna bother with it, get FI, cause learning to dial in a carb is all about changin' jets, makin' runs, smellin' like fuel, sweatin', and drinkin' beer.

A-men, and it will never stop because once you learn how to dive in to these awesome nikki's you always look for that little extra bit of ummph!

In my opinion the Dellorto hands down; as in no question about it. Best and smoothest carb I've ever had all around. Ive seen others not liking them, but are they true RB modified? Doubt it. All you have to do is buy the RB air filter and call it a RB modified Dellorto. My Dellorto is smoother than my stock EFI with gobs more power. With the Dellorto, you set it and forget it. A Flawless carb. Great for autocrossing and street.

Weber is great for tracking, and probably the best at that, but not great on the street. Finicky on the rpms. Tricky to tune on a daily driver. Can stumble at times. BUt for power, the way to go. Power does snap which is a bit annoying for a daily driver.

Nikki- Not as powerful as the Weber or Dellorto, stumbles on left turns - BAD. Can buck at times. Wasn't pleased. Kept tuning it untill I was blue in the face. HArd to balance power and smoothness. Tune it for power and it runs like *** at lower rpm's. You can get great power out of it, but at a severe cost to other rpm's. Not a good choice for an all around carb. Probably good for a specific type of racing.

Holly - never had one, and everyone I know with, one hated it. My advice is to keep it for V-8's. Most people put too big of a holly on their rotary and have a Bitch if a time tuning it.

Mikuni - horrible gas meilage on the street and I'd put it a notch under the Dellorto. I never liked mine. But a decent carb and should be a contender w/ Weber and Dellorto if you don't mind the constant tuning and really bad mileage.


Thats my advice, take it or leave it.

Carb upgrades can be better for power on something like a stock GSL-SE, but going standalone would likely lead to better results all around if you know how to tune.
Now, if you compare throttle bodies to equivalent carbs, for example a DCOE throttle body versus a DCOE carb, EFI wins hands down.
Basically, you have the same physical design, except a much greater degree of control over the fuel mixture, which is exactly what you'd need to 'balance it out'. You can go from max power mode, to gas saving mode quite literally with the push of a single button.
Personally, I would go with a carb style TB (like an IDF for example) and never look back. Well, actually, I did that already.. heh
To me it's pointless to argue about which carb is better because all those carb styles, weber,mikuni,dell'orto, in my opinion, are obsolete by their equivalent throttle bodies.

Though, I do think a modded-nikki would be a great performer all around, and a great value. No extra manifolds to buy, looks stock, and all the stock stuff goes back on. I would consider one if I was in the market for another intake setup. Seems to have great support and decent upgrade potential, once modified you can get jets for it pretty easy, the 4 barrell advantage for street driving...

Bottom line is you got to weigh your options carefully, against what you can do/afford. In the end, it becomes a personal decision because a lot of these setups are really similar when it comes down to it.

sure. but i'm a broke a$$ college student. mod it for free for me will ya???
don't know wtf i'm doin, okay!.... LoL.

so you're meaning to say.. i should ditch my mikuni and 48 IDA for a sterling crab... when tuning a weber is so much easier in comparison to any nikki and is also much physically capable of doing more what than i even want it to do.

and btw, i rode in carlos' sterling equipped nikki before. i don't know what the big deal you're talking about ....... wacky's bro-in-law w/ the 48 IDA 12 SP is faster.

no disrespect, but we folks here in L.A. like simplicity. what i'm saying is that if complications can be avoided, such as weber vs. nikki, then why not do it. i really do see the nikki as a complicated piece. call me w/ a simple mind, but that's how i rolll. lastly, the real turn-off for me is the pricing for a modified sterling nikki. i might as well get a weber.

but of course by all means, do stick to what you like and do. that's what keeps the world a happy place. diversity and flavor.

i'm not a non-conformist. i view the sterling nikki as a hippie type thangggg i'd prefer to avoid it.

I dunno where you get a "hippie type thang"?! What the **** is that about?
I sure don't need to "convert" you, Lo Duck; I couldn't give a **** one way or another. But I do see you ****-talk modded Nikkis all the time here, and it would be tolerable...if you had any clue wtf you were talking about - which by your own admission here, you don't.
As far as having ridden around with Carlos and being unimpressed, lemme ask you this: Do you think Carlos is actually smarter than YOU? You think Carlos really knows anything about what he's doing? You just got done saying the Nikki is "complicated".
Lemme tell ya something about Carlos...We've tried to help him and accomidate him just about as much as we possibly could, and still he refuses to do our hard work justice.
Carlos' carb is an ill representation of the Sterling Carb simply because he has always refused to heed my jetting advise. Carlos is just so certain that he knows better than me, and consequently his car is slow. He has actually asked for jetting advise, and then argued with me about it!
Right from the start Carlos told us how to cut his venturis, because he was certain he knew better than me. I said the carb would fall flat on it's face. It did. Then he decided to go with what we always knew after much testing. But still he was a bullhead about the jetting.
