Hey guys i was wanting to know if i could put a side draft carb on my TII....every webite i go to only has carb kits for N/A's, do they even make a kit for the 13B-T? and is there any benefits to running a carb on a turbo rotary. My engine bay is swallowing my engine now and i love all the extra space....my fan shroud is gone, factory(bulky) intake plumbing is gone, power steering is gone, and my emissions is removed, but i want more space like this guys boosted RX-7, which is carbed.

You would need either a draw through or blow through setup. It means either a special turbo with special seals to withstand the gas, or a carb box . With a draw through the turbo is after the carb, with a blow through, the turbo is before the carb.

My limited knowledge .

Dood that engine bay is totally ghettoe except for teh badass fuel system. Im not saying that car is bad, but its totally not badass because it has 2 many ghettoe parts. If a clean engine bay is teh most important thing in the world then why dont you also ditch your turbo and intercooler to make more room and have fewer parts? Yeah, thats what I thought. U can also have a clean engine bay with EFI and get better power AND better gas mileage than a carb. I have seen some fuel injection stuff that bolts on to carb intake parts if you want something different than the stock system.

Good luck!

thanks guys....i want a carb so i dont have to worry about all the electronic crap and to have a tidy bay, i never owned a carbed car so i really dont know what a blow through setup is but ill research some more....i definitely want the turbo before the carb.

try jus gettin a marine carb cuz they come ready to handle Pressure being blown , and a Carb box the only carb boxes ive seen are Holley , and racingbeat .

Why in gods name would go you go with carb if you could have the tuneability and reliability of EFI...hrmmmm

Some people don't like screwing with EFI and trust carbed setups more because they're usually a little more self-regulating then most EFI systems.

Unless you have a good stand-alone setup and the proper instruments to at least street tune it you're playing with fire when running modified boost levels.

:shudder: turbos are sooo~ scary.... NA4LIFE. :P

If you stick with the carbed setup, please keep us updated. It's always nice to see unique setups.

just do it.

you could put the carb before or after the ocmpressor. needing a special turbo is poopoo. just slap on any old snail and go to town.

bcool

Yes..just "slap it on" and you'll be good to go, the idea of that much fuel going into a very hot turbo scares me for some reason, and i suggest you stay with EFI in my opinion, you'll still be a whole hell of alot safer when you tune w/ it then the carb, at least you wont have much issue with it changeing.

I think you mean they are too stupid to attempt to try to figure out EFI systems. Carb's are not more self-regulating than an EFI system, in fact, they are substantially less regulating. Ever hear of vapor-lock? A choke... and on and on and on...

If you're running a modified car period, you are playing with fire. Step up and manage it effectively or find a new hobby.

There's nothing unique about using venturi technology from the 18th century...

One suggestion to clean up your engine bay is to run a supercharger, no intercooler and a stand-alone EFI system. You'll have constant responsiveness, little plumbing outside your intake which you could reduce by having a hole in your hood directly to the suction side of the compressor.

NA...slow for life



Be fun to meet you at the dealership in a couple weeks Urizen...

Obviously this comment comes from personal experience... slap it on, just do it and any old turbo will work just fine indeed. I can't even comprehend the ignorance level here...

your a noob. the only way to learn is from experience. if it works it works. he was wondering if you could carb a tII.

yes. yes you can. its been done. infact in the same exact way i stated before. so keep your retarted elitest comments to yourself., obviousy people here are too scared to do anything decent to their car. they stop and theorise about doing things and that hinders them.

sure a cork sport is loud, who cares? throw it on. is the turbo gonna make poiwer uptop? who cares its still gonna work.

my $.02

also go to hmt where real men work on cars.

noob...ok, this coming from a 21 yr old. You have no idea what I've done to mine and how long I've been at this. My retarted elitist comments have come from years of experience, yours have come from what, playing around with your buddies car in junior high and suddenly you're an expert?

Yes, you are right. If it works it works and "good enough"... words of wisdom to live by. You certainly set your expectations high. At least I had a good laugh from this one although as sad as it is.

hey carb boy, want some engine ****?

But seriously, why sticking with a 100years old technologies when you can have a good standalone for half the price of a good carb setup.

But.... NA.... is.... better?! I like your supercharging idea though, the few supercharged 13b setups I've seen (gehtto or not) look fun. I've always liked the sound of a supercharger too.

The rotary just seems too perfect for turbo applications because of it's exhaust structure though. It's almost like putting some part of the rotary to waste by boosting it with anything different.

I hope you're bringing that 20b unicorn of yours to the meet, looking forward to seeing it in person.

ok, im new here, but this topic is very close to home. ive seen some actual good facts here, but 50% of it is far from truth. if youve never messed with sides before, you dont want one on a daily if you have little experience with them.

for one thing, anything is possible as long as your budget and experience allows.

and about carbs themselves, be prepared to retune it every time your local area goes through a signifigant change in barometric pressure (aka weather) best case scenario is youll be tuning it at a minimum of 2 times a year, if youre lucky. carb setups in general are good for power, just as much as efi for example. peak power is nice, but its the power under the curve that makes the car fun to drive.

you will make a sacrifice going to carbs though. you set them for one good section of the powerband that you feel is best (going turbo youll def need it rich up top, so youre bottom end will suffer as a result of that)

efi has its one big advantage. it always does its best to keep a/f at the optimum ratio. in carbs, its your job to make sure its keeping things where its supposed to be.

regardless though, it is fun going to track events, popping your hood, tuning your setup for that day, and retuning back for casual driving at a whim when you get good at it.

youll hear me mention volkswagens all the time as i keep posting. i like them. here is something off of our forums, the Carb/ITB forums. completely dedicated to running carbs all the time. heres the FAQ that should prove very helpful. there isnt anything about adding boost, but its one of the better resources for info on this subject.

Fricken waste of time.
If you can't handle the "modern" electronics of the stock FC3S engine control system, you shouldn't be driving the car in the first place.

werd up if u want carbs rock a 12A dood...go back to first gens....WAYYY back....lol

if ur not happy with this configuration....then u totaly need to move on to another car...it just aint for you then....first gens are light and are carburated...head to the first gen fourm...they would give you more intel on taht....

Way back? They were made right up to where our cars were (85 end of 1st gens to 86 start of second gens).

Its his car and his money.

cardzrule

RX-7s came with EFI starting in 1984 even tho the carbed 12As lingered on for 2 years. Anyhow carbed RX-7s are older than you and me lol. WTF do you mean by Way back? Dood that IS way back!

Yeah but like that RETed guy said its better to get a car you like than to try and make a modern car into an older model. Also it sounds like this dood wants to remove everything he doesnt understand and I think that means pretty much teh whole car is his case. His money is better off spent on an older car that he can maybe understand.

i have a carb, my step dad tunes carbed race engines for a living and the manifold is under 300 bucks so thats damn cheap, but as i researched last night i found that no matter how the carb setup is, before or after the turbo, turbocharged carbed engines are way more prone to detonation.....so as a daily driver, this possibly would be a waste of time and money........oh well, more motivation to spend my money on a Turbonetics T04.

I know about carb'd RX-7's. I was born the last year they made them :o!

But its still his money and what he wants to do with it. Some people can do wonder with carbs and aren't familiar with FI. I don't agree that carbs are better, like others, I think its closer to home for some people.

Its his money, do what you want with your car.

psychotic7

oh yea and it's not that i dont understand EFI.....its just that i love the fact that 13b's are so very small and the engine bay is huge.......when i whip a bloated, huge engine domestic and i laugh and say, "dude you just got whipped by a 1.3 litter" and they dont believe me, so i pull over and pop the hood and they're like DAMN! well with less clutter, the engine bay will look way bigger and they'll probably just pass out......the detonation thing scares me so ill probably get a cheap *** Megasquirt unit and be done with it, plus with a TII i will want total control over my air/fuel ratios.....thanks for the input guys, i just saw that guy's turbo RX-7 on car domain and loved all the room.
