OK.....I AM GOING carb.......whom of you have done this? What am I looking at for linkages, what dellorto carb should i go with, and I am ordering the header and manifold from racing beat and having a custom downpipe made, and install a basic presilencer. What do i need so that the carb will link to my throttle? Since my injectors will be gone, atleast 2 eith the manifold what do i do there? As far is ignition which year seven do i need and what do i need. And will a Dellorto carb be already setup for this or do i have to order somehting custom, as far as carb runners or whatever.


also is there a current right up on a HOW-TO for a carb setup.......please no flames, no more arguments, i have 2 weeks to get this done and need all the help you guys can give me, sound fair?

p.s.~thanx in advance for all the help you can give....links ETC ETC

Screw Dell'Orto unless you like hunting for nonexistent parts.

Fabricating a throttle linkage is not too difficult - to be honest, if that will give you problems then you'll probably have a very hard time figuring out how to tune a carb properly.

Grab a first gen distributor too.

man... A carb and distributor????

Since you are going backwards in car technology, you might want this hitch and harness thing that my neighbor has down the street. It hooks up to an actually horse and with that horse it will give you at least one more HP than you have now.

Sorry I have been wanting to say that since you first started all these lame carb threads.

In all seriousness though are you planning on making just a drag car that is not driven on the street or something? Is that why you are convinced a carb is the way to go?

more power=more fun, and a bet with my dad that i can smoke his 69 camaro with a streetport carb setup, and 75 hp shot of N20, think i can take him, I DO

This is a NA right?

The rear end and tranny can only handle around 220 HP you know? Seen a couple people now shear off NA half shafts with a 75 wet shot on a stock FI system.

Hope you are planning to upgrade them as well.

crossbar17

yup tII tranny, rear end, and custom drive shaft

Racing Beat just came out with a Holley carb set up. If they are just coming out with this then it must be good for some applications. RB say its a nice HP increase for the price. I saw a side draft weber and intake today on ebay for 200. (you dont need to use a distributor.) FI is the best way for a daily driver and over all performance but at a high price. If he needs power fast and cheap then the carb may be his best solution for now.

Heck get the atkins SC set up and NOS that and rip the drive line right off the car:-)

NZConvertible

Yeah, you just stick the plug wires into the Weber...

Of course you need a distributor! Jeez...

RETed

Uh, no.&nbsp Any gains made over the stock FI system is probably due to the removal of the AFM.&nbsp I put money you'll never get the carb to work as well as the stock FI system in day-to-day street driving...

I have a Weber side draft. Sure it is in a REPU but the engine is from an '86 N/A. I never drove a N/A 2nd gen so I can't really compare it to the stock FI setup but I don't think having a carb is really all that. I doubt I have more than 120 rwhp. I keep thinking about converting it to the fuel injected setup just because of the pain involved in getting the carb adjusted, jetted and timing set optimally. I don't think there is any benefit to using the carb unless you are racing in some class that requires it.

FYI, it is incredibly easy to get set up so it runs reasonably well. You can get plates for real cheap from RB to remove all the vaccuum crap (AC &CV) off the intake manifold and to remove the EGR. You can get a fuel injector plug kit from them too. From there it is just bolt the carb on, drop a dizzy in, wire up some ignition coils and away you go, very roughly until it is adjusted properly.

crossbar17

so what can i do if i keep it a FI? redo my exhaust a little better nobody in Maine has a clue about my SAFC, an di can get the carb setup for around 300-350 total plus injector plugs and the ignition, so why isnt it worth it, i dont care about gas, cause its not a daily driver, and when i street port it i want as much gain as possible, whats the delio?? i dont want a turbo, and if guided correctly and adjusted right i should be good with a carb, my dad has spent alot of time tunning carbs so what the diff?? and also if i get just a strait Dellorto side draft carb #48 what do i have to do to modify it to fit on?? do throttle cables allighn????

NZConvertible

Ted’s already told you the exhaust can be the same! Dunno about the US, but spare distributors are hard to find and expensive over here. I think this’ll cost more than you realise In your other post you said you wanted to do low-13s. This will be achieved for a lot less money with a mildly modded turbo than a carbed, ported, nitroused NA.

Felix Wankel

Dizzys aren't too hard to find in the US. You guys are lucky, you can get a hold of 12AT boost retard dizzys

I wasnt refering to the weber set up

Th atkins guy told me with there set up you didnt need one I dont quite understand that but thats what he said.

go with a racing beat 6 pt intake manifold, holley 600, 1st gen distributor, block off plates for the egr and acv, jb weld the injector holes in the middle side housing, and u should be good.. eliminate all that fuel injection crap....no more failing secondaries... no more 3800 rpm hesitation.. plus the engine bay looks much much cleaner... much more power than any fuel injection...

FPrep2ndGenRX7

Then explain to me all the F1, IRL, CART, WRC, etc.....cars using FI? I'm sure they would use carbs if there was more power to be had but there is not. Maybe the same amount of power with both setups properly tuned with the same exhaust configs and the same length intake runners and the no emissions to deal with but not more power just because its a carb.

Don't Nascars produce more power than IRL cars? (you're point is right, but I don't like IRL cars)

Samps

If you are going to spend $1000 on a carb set-up. Why not get a haltech and eliminate the AFM and end up with the best of both worlds. It will cost you to have it tuned, but in the end, you will have a much better automobile. And considering you want to add nitrous, a haltech could help even more. Either way you're gonna spend over a thousand bucks; might as well get an upgrade for the money. And if you decide to go turbo in the future, a haltech can make things even better.

FPrep2ndGenRX7

NASCAR has 358ci(5.7 liters) dispalcement max and make somewhere in the neighborhood of 650-700HP maybe more. IRL has a max displacement of 3.5 liters and the rpm is limited to 10,700rpm. They still make 700HP. I don't see a difference.

peejay

NASCAR runs on pump gasoline

FPrep2ndGenRX7

I forgot about that.

Instead we have vapour lock, poor cold running, loss of midrange, higher fuel consumption, higher emissions, no temp and altitude correction, blah, blah... Sorry to sound nasty, but that statement is based on pure ignorance. A Holley making more power than any fuel injection? Someone better tell MoTec and Haltech they’re doing it all wrong...

I’ve got a comment on these carb vs. EFI debates. I’m sure you’ve all figured out what I prefer, but really if you want to go carb, I don’t care. If it’s what you want, that’s fine with me. Really!
What annoys the hell outta me is every one of these threads is crammed full of wrong information from the pro-carb guys about EFI, mostly based on plain ol’ ignorance. Just because EFI scares you, doesn’t make it crap. If we’re going to have these debates, let’s base them on engineering facts instead of mistruths fed by some mechanic whose only ever worked on carbed V8’s.
The carb’s biggest advantage is cost, so if you want to carb your car because you can’t afford EFI, tell us! (But check how the costs really compare first, you might be surprised.) Just don’t come here and say “I’m getting a carb because I want heaps more power”, coz that’ll always start a war!
