-Yeah, just one cylinder and it seems to be running fine. It's idling very smoothly. If I remember correctly, it was only tapped into one runner in the stock setup, too. I think it was tapped into the 3rd cylinder (counting from the cam gear). I could be wrong, though.
Phydeaux wrote: "You really only needed to hook the brake booster up to one runner, it makes more then enough vacuum."
-I know that most sidedraft manifolds have a brake booster tap in the 1st runner. But, I've also heard that the A20A doesn't have great vacuum. I talked to Brian Waters, a local Honda mechanic and a friend of mine, and he recommended the 3 runners for braking, 1 runner for PCV setup. Funstick also recommended tapping multiple runners for braking vacuum.
I just didnt want to take the chance of having to remove the manifold once it was installed - so I tapped them all. LOL.
"Tap them all, let the DCOEs sort it out." That's my motto :lol

-LOL. Man, you don't want me in your engine for a month! I went nutz and just started tearing stuff out. If it looked like a vacuum line - I yanked it. Power steering fluid and coolant were everywhere! LOL!

-I have size 40 DCOEs with 30mm main venturis (chokes). I want to get 32 or 34mm chokes eventually. Basically, you pick the size choke you need for your engine type and then match the DCOE size with it. 40 DCOEs are a great size for power in our 2.0L single cam engines.

nice,
hey how much would it cost me if "73rd Street Tool and Die (Cincinnati)" would make the intake for me?
thanks.
Alex.

-I asked them that in case anyone from the board wanted a sidedrafts manifold. It would be around the same cost - maybe more. They gave me a price up front and it was a bit more work than they counted on. I paid $250 for mine. I gave them these parts along with some drawings and instructions:
1. stock intake manifold from A20A1
2. Mazda DCOEs manifold
3. Aluminum tubing
Basically, I supplied all the parts. They machined the manifolds, shaped the aluminum tubes and welded it all together to my specs. I think they'd do it again for $300 or less.
If you're serious about it, I can talk to them. Email me.

good to hear. if you want to kow more about the teg tranny setup get in touch with andy or myself.

hey site, what did you end up doing with supporting the weight of the carbs?
- Joe
I'd love to see some pics.

-I remember talking with you about it at the meet. I was concerned about the weight of the carbs on the manifold. You agreed. So here's what I did . . . nothing! LOL. I talked to PhydeauX about it and his welder told him the welds were strong and not to sweat it. Eventually I'll add some support from the top. I have some ideas.

I made mine with a hacksaw (well sawzall) and a hammer, there is nothing wrong with that. You can call up Pierce Manifolds and they can get you some pre cut DCOE flanges so you don't need to hack up another manifold. That'll run you about $80 or so, unless you can get a realy good deal on the manifold then thats the way to go.

hmmm me thinks its time for a indvidual runner efi intake with 4 TB's

Funstick, individual throttle bodies would be INCREDIBLE!
A20A1 - I've seen the Weber DCOEs EFI-style at PierceManifolds.com, too. Funstick mentioned someone who talked about making normal DCOEs into EFI with some work. Too cool.

OK, one question only, and a dumb one: Will control work on the current ECU? I doubt it, but I might as well ask. If I don't turbo, this is the direction I'm going. I've finally settled it out

Thats ok, the twm is twice that :p. I still have that one idea I mentioned to you before for quad tb's. I just need to find some wrecks to get throtte bodys from.
andy
Hmm what about the coolant lines that used to go the the stock manifold... did you just run a hose from one end to the other... I may have mentioned this a while back tho?
Anyways I think vibration is the main reason I would want to get a lower brace for the carbs.
- llia
Connect the hoses and its fine. I've been running mine with no lower brace for months with no problems.
andy
andy i do like the dual tb 2bbl idea ?? can it be packeged ?? and stuffing ic pipping is going to be a pita LOL.

Okay, lemme just say this. I didn't realize what I had in my car until just right now. The DCOEs were giving a very noticeable power difference before, but after some adjustments just now - they're amazing!
I just advanced my timing an 1/8 of an inch, maybe less. It took care of the DCOEs backfiring (they were backfiring infrequently at idle). I also installed an Accel coil. I took it out for a drive and WOW! The acceleration is much STRONGER and FASTER from idle to 6000 rpm. At 6500, it pings mad. I'm thinking it could be any (or all) of three things:
1. Accel coil is only good to 6500
2. My chokes are 30mms and I'm leaning out up top (need 34mms)
3. I've advanced the timing a bit too much
I don't even know what the hell causes pinging, but I don't think it's #3 - I barely advanced it. I don't know what "vacuum advance" is either, so I guess I didn't touch it :lol
What causes pinging? Could it be the Accel coil or my leaning out in the high RPMs?
Feels like I'm in a race car. It actually pushes me into my seat some. If my wife weren't recovering from surgery and in need of attention, I wouldn't be typing this. I'd be driving that thing like a BAT OUTTA HELL! Kick arse.
I don't even have upgraded exhaust yet. Or headers. Or anything, really. All I've done to the 3G is DCOEs (PhydeauX I owe you steak! Call me when you're in Cincy.) and the freaking Accel coil. That's it!
Get you some DCOEs.

Time to get in that group buy yasu is talking about for cams .
andy
No kidding! I can't wait to add some more mods and see what this thing feels like. By the way, I turned back the advance a wee bit and hopefully that will take care of the pinging at 6500. I'd give it a run and see, but the kids are nappin', and everytime I start the car it wakes them up! LOL. You hit it on the head, PhydeauX, when you said the DCOEs sound like a vintage race car.
Mike Clark
what octane do you use? and it could be your vacuum advance... try and hook it up to a single runner. or is that how you have it?
