This thread is very entertaining. Wish I have the time to wait for the next episode.

 

Long time no argue, fuckface

I must say Ray, you never rode in my car with the Sterling Carb. You rode with me on an earlier modded nikki that wasn't tuned in yet.

And for the record Dennis, I did follow your advice in jetting (eventually) and the last few months I had my car, it had the jetting you recommended. So don't gimme any ****.

Ray, you can ask Ryan how the car felt when the sterling carb was dialed in to the best of my ability, and following Dennis' advice. He was genuinely surprised at how the car pulled.

 

...And then you blew up your engine.
Good going, ya Frito-eating ****.

 

so you mean to say my own personal opinion is **** talking. great.
if you don't like what i think i know is good, then leave it be.

people like you take things too seriously nowadays... where's the fun in that.

 

Im using a 600 cfm edelbrock performer on my 2nd gen 6 port . It worked pretty good right out of the box on my racing beat manifold and 1/2 open carb spacer . I was in the process of tuning it with my lm-1 when i got bit by the turbo bug , so im currently setting it up for a blow-thru ~6-8ps . From my research they only mods that will need to be done to the carb is edelbrocks marine accelerator pump for up to 10psi (the point where the brass floats crush) I've read the floats can handle up to 15psi but a more reliable source mentioned 10psi . I also have the off-road spring loaded needles and seats . anyway back to the subject at hand ... i haven't used any other carbs before but the edelbrock was inexpensive , easy to tune , and it worked .... im sure not as good as the other carbs stated but it did work . Just wanted to share my experience with the edelbrock

 

what does he pack the venturis full of bud before he ships them out?
i dont get it...?

 

Yeah, I know. I always wondered if there was a connection between following your jetting advice and blowing those seals...

 

Alright, now that the personal jabs are out of the way...

Back to the discussion at hand.

Here's what I'm looking for, and since I'm the thread starter, that's all that matters.

I want more power than the stock set-up. I currently have a 12A, stock. My Racing Beat full streetport exhaust will be here on Monday. I want an increase in performance over the stock carburator. I don't want to have to tune and re-jet the carb once a month. I don't mind putting in the tuning time once or twice, but I also don't want to have to **** with it all the time.

I've always loved the looks of the Dellorto, the way it wraps around. The guy who got me into RX-7s had one on his 82 waaaaay back in 1984. Of course, he had a SP 13B and it was the fastest car I had ever ridden in at the time.

So, my top 3 choices are:

1) Go with my good buddy Dennis and the modded Nikki.
2) Hunt down a Dellorto somewhere. Ebay or whatever.
3) Go with the EFI set-up from Rotary Shack.

Whatever I pick, I would like to be able to use it with a 13B when it's time to upgrade in the spring. I know a Dellorto can swap over. I'm pretty sure the EFI can swap over. Not so sure about the Sterling. Of course, if I go with a 13B turbo, it's all moot. But, I believe in building a system that is capable of more than you're asking of it... Hence me ordering the full SP exhaust system from Racing Beat even though I currently do not have a streetport. I'm building for the future, not just for now.

 

1. Well, any carb you get WILL require some re-jetting down the line. Buy a shelf item and dont jet it..someone will own you.

2. Plans for future upgrade? Invest on a carb that will work good for that application. Otherwise, you may ended up JUNKING that carb. there goes cha-ching!!!! Noticed that I said GOOD as ok is not good enough for me.

 

i can attest to this: once a nikki is set, it's good about staying in tune. so that's a plus! i think your decision will have to be made when you truly decide on what your planning on doing later. cause if your going turbo, that can change which setup you choose. honestly, i feel that if you are still even thinking about the EFI... do it. throw down the cash now and enjoy from here on out. people stay away from FI because of cost. not because it sux.

 

...And typical of how much a knowitall wannabe you are, it never did occur to you that you just can't drive fer ****.
Here's a hint, moron- whoever told you it would be ok to rev up that bucket o' bolts to 12 grand was lying to ya.

Forget about the Sterling Carb, Kev. I can already gaurantee you you'll have to make more than one change. Hell, TWO changes is minimum...one (if you're as God-like a Carlos) to get it dialed in right, and one to check that it's as good as it can get.
-And I don't care who you are, or what carb you have, nothing is "optimally tuned" right out of the box, and you're hard pressed to nail it perfectly the first time, either. It may feel like it "must be", but that's only because it's so much better than the previous piece of **** you were running.
If you don't like the idea of dialing in a power curve via jetting, the don't get a Sterling because there's so much more to tune than just fuel jet sizes.

 

Perfectly put.

 

I think you're misunderstanding me. By me saying do it once or twice and leave it alone, I mean I don't want to have to adjust it every goddamn weekend, or change the jets because it's cloudy outside. Follow me?

 

so how much will a full fuel injection system cost?

 

it's not ok?

 

what's the difference between down draft and side draft manifold? how about that wrap around type where the carb sits over the top of the engine? advantages/disadvantages?

 

A 350Z can whoop a Mustang? what f@*$king planet are you from???

Let me guess your 1st gen probably makes 300RWHP as well right?

And you redline it in every gear.

And never got a ticket?

 

It's pretty self-explanatory. A side draft carb is mounted horizontally while a down draft is mounted vertically. The wrap around is a side draft setup.

 

So is it true that a 12a needs the inlet ports welded up and an efi centerplate installed on re-build to become fuel injected? thats what i've been tolt so i got two efi centerplates and yes there are injector holes in the top. Thanks for any help.

 

What do you mean by "inlet ports welded up?"

 

Back to the original question, here is some real world data. Haltech vs. Holley vs. Dellorto:

http://twminduction.com/ThrottleBody/carb_vs_fi.pdf

They also try 50mm vs. 25mm stacks too. Shorter = more HP above 6700rpms but they didn't show the torque curve.

You might try to find the previous month's article which is a 3 carb vs carb comparison.

 

i can agree that the Dell is quite easy to tune once you learn what you're doing, but that's a 2000 RPM range you're attesting to there, which i must say i'm skeptical of it achieving with the standard RB manifold setup. what porting? which manifold are you running with that Dell?

 

Alright quit the bickering you guys. Everyone has opinions and they are as you can see Kev, biased one way or another. It's cost vs performance, vs looks, vs persopnal preference. As Carroll Smith said, its a "horses for courses" kinda thing.


As to the comment that the 44 mikuni beat a 48 weber, remember that the 44 and 48 is throttle bore size, not choke size. So that statement is useless without knowing the choke sizes.

DASUPACAT- generally speaking, the longer the manifold the lower peak hp and torque are achieved. Short manifolds like the lake cities are for hi rpm use, like the downdraft manifolds for the IDA/IDF. Wraparound manifolds are for more street use as the torque and hp peak is shifted into the midrange.

 

TBI

pros- tuneable via laptop, probably best overall mixture control and power possibilities.

cons- most expensive, no turn key kit availible AFAIK, also still uses a wet manifold so you still have a problem with fuel seperation and drop out that you would with a carb so. Direct or port injection would be the absolute best.

 

Holley

pros- highest flow potential of any manifold Ive tested ( including stock, 2bbl wrap around, my modded stocker and stocker). Parts readily availible at any local speed shop.

cons- stumbles in turns due to carb mounted 90* than intended by Holley. Not reccomended for autox or road racing.
