Discussion , Boost N' Carbs - Blow & Draw Thru Turbo / Supercharging

[3rdGenFanatic]

Come on man, don't leave us hanging! We need to get in contact with the owner of that thing!

It's not a carb, it's the same engine we snatch those intake adapters off of for our carbs.

[meohmy01]

the late 80's civics were fuel injected. i'm not sure what setup they had but it looked like that. i think maybe it was some sort of tbi. i don't think that's a carb

[iiviasterp]

yea thats a D15 throtle body injection civic......ive seen that done a few times

[k-roy]

Where is the carb?
That is a 3rd gen civic with FI, my best friend had one. It was the first Honda I ever drove

[TJ89Accord]

Yah it sais that he has a Holley four barrel.

[wprocomp]

cool...i wonder how good it runs though...I just picked a demon carb today for $250....hmm

[Illicit3rdgenRacer]

actually its easier to turbo a carburatered car than a fuel injected car its less to worry about

[87Hybrid]

That is the throttle body injection on a 4th gen civic not a carbed car!

[myaccord7]

my brother had the same engine in his 90 civic. they are F.I., but they do look like carbs, BUT NOT.

yeah 16 valve? No carb! lol! 12 valve then ya got a carb!

[TJ89Accord]

I wonder why he wrote that he has a 4 barrel carb though. Thats kinda weird. Maybe he converted it to carb???

why don't you just try to find some info about running a dual weber setup with dual turbo. and if you think that's impossible, i have some pics of this. So, dual turbo on a b20a twin weber?? :super:

[Sean]

actually if you get one of my upcomming turbo kits with the gm ecm package you plunk the carb in the garabage.

[A20A1]

I think holley made a 2bbl adapter for the civic... so I guess he just built up a 4bbl adapter to the 2bbl base and went from there.

[wprocomp]

yes A20 is correct...if you look closely you can see a float bowl peeking out...also civic throttle bodies are very tiny...not like the one in the pic...and that turbonectics hat is for a holley quad...

[myaccord7]

this is a long term goal but i need to know what i should get. ive seen pictures of preludes, civics. and accords with the DCOE duel carbs with a turbo. what do i need to do to my fuel managment? i dont have my dcoe's in yet but right now my car is carb. if i want a turbo on my dcoe's what do i need to do with my fuel pump, jets on the dcoe, pressure,.....? also does anyone have any of the pictures of a dcoe with a turbo??

thanks

You need something to raise the fuel pressure in response to boost... and you need a fuel pump to keep up with the demand.

Here's a nice shot it's not a honda but it looks cool

[myaccord7]

do i need to do anything with the jets? i have the dcoe 40's. also anyone have any pictures of the dcoe with the direct port nitrous on it? thanks again
zach

anyone have anything???? any help at all?
zach

i would like to do a turbo. i am going to do the dcoes. if its to much money and work, i'll just do a direct port nitrous kit on the dcoes. anyone have any suggestions about doing that?
thanks
zach

that prelude with the turbo dcoe is my wet dream. i dont understand it. why and how does it have a 92 Acura Integra stock fuel injectors and fuel rail??? how does it have carbs and fuel injection???? would i have to do anything special to the carbs if i what to do direct port? like jet them.....? anything?
zach

do i need to get a different fuel pump if i get nitrous? how would i get fuel pressure?
zach

anyone know? if i get direct port nitrous, does it matter if my car is carb and not efi? would i need to do anything different? are there different direct port systems, like wet and dry?
zach

[ET2]

Something like this ?

if you're really serious about going turbo, i'd HIGHLY suggest you look into seans ECU kit. It'll convert your carb motor to EFI with a LOT less hassle and work and you'll get better performance and reliability as apposed to trying to boost carbs.

You need something to raise the fuel pressure in response to boost... and you need a fuel pump to keep up with the demand.

well Thermodynamically speaking, an NA car operates at 1 Atmospheric Pressure (even tho is little less than that) lets assume it does. So it means it operates at 14.69 psi. lets round it to 15psi. Which is standard. so when we boost it, they say they are boosting at 6psi for min or what not. So ur running at an average of 21psi intotal. Cause boost is always over the Standard pressure condition.

but for 15 psi of air pressure at Standard, we run our fuel pressure at 37psi stock. Right? So for boosting at 6psi we would have 37+ (3*6) = 37+18 = 55psi of fuel pressure. Is that right Mike? Whats the A/F reading at that fuel and air combination. 55psi of fuel and 21psi of air. thats like more than twice the amount of air. So ur running a little rich then right?

[PhydeauX]

Well the 4port fogger system is definitely easier, and cheaper. There were some pics posted of a prelude running a dual stage system. Looked alot like a birds nest of braided steel lines . The only requirement is that it has to be a wet system (I'm not an expert, do they even make dry fogger systems). You install it just like you would on any other 4 cyl car, nothing special for the dcoes.

[A20A1]

hehe maybe I stated that wrong... just go +3 or +4 psi of fuel over whatever the boost you are running... so it acts like the carb isn't being boosted at all.

If you add boost and not fuel PSI then the fuel gets forced back thru the fuel line or just wont flow into the carb.

Oh the good old Nissan/Datsun 1600. That is one hell of a race engine, now if I can get some extra money to do some stuff with the 1600 in my truck.
