again thanks for all the positive support. Now to answer a bunch of questions.
Carb sizing: When i was trying to select a carburetor i went through the weber thread in R and D and a couple of the guys that had been running A20's on webers said they were using 30mm and 32mm chokes. So i figured that with the big cam a 34mm would probably suffice. I also had throttle response as my top priority so i didn't wanna go to big.
As far as tuning goes i plan to do it myself. I have access to a wideband O2 sensor and tuned my own weber so i think i should be able to tune this setup as well.
Yes that is jb weld.... this is the first time i'd welded aluminum so i had some holes in my welding. It is also a combination of metal putty and jb weld holding the vacuum log on. Eventually i will probably go through and build a nicer manifold. But for right now this works and i didn't want to go through the trouble and time of making a nice manifold to realize afterwards that the carbs were not sized properly or soemthing and have to scrap it all. And this is a function over fashion car so i am not bothered by the less than perfect manifold. This manifold is not PVC but i did give that a try i just couldn't find an epoxy that would hold the runners together once it warmed up. So i've actualy had the car running twice before this but each time the manifold fell apart. Woooops.
I made the manifold long trying to get more low end torque because the 282 cam destroyed the torque down low.
Velocity stacks would be cool but as you said i don't know if they'll fit between the firewall and the carbs. And my carbs already have a velocity stack shape built into the inlets. They are a 50mm inlet that necks down to 34mm. And rjudgey nailed the hood scoop idea. I think that i am going to get one this winter and then make a rain shield of some sort for whatever filtering system i decide to run.

Dyno'd the accord. It made 104HP 117TQ.... And blew smoke everywhere. I guess the 210K motor really is done
Man this is sick. 4 carbs. I've got to see a video of this. Props to you for staying true to carbs.

dam thats sick
Does it run good?
more pics would be nice, and i wonder how much it would put out in a dyno run......
wow that looks pretty cool, i WOULD also like to see more pics of course. good luck with the tune and awesome job bro
Only reason why i'm questioning the carb size is i've tried choke sizes from 36-42mm and the best ones work at 38-42mm most power from 40-42mm difference is next to nothing on these though maybe a 2-3bhp but huge difference from 34-38mm found the engine just struggled to rev and lack lots of power. And this is on a A18 which are normally not reknowned for high flow or lots of bhp but do produce excellent low end torque due to the curvy inlet ports and the curvy weber manifolds. MOST power i've had out of A18 was 186bhp with a bif valve conversion and a ton load of extensive headwork, the exhaust cast header could have been ditched but even with a Pacesetter would probably have only gained a few bhp as the cast one was heavily moddified.
The bore spacing on the bike carsb are pretty much all the same so you could most likely try carbs from another bike with bigger bores maybe.
But anyways you may be okay on this if you want good low end you should get it but i wouldn't expect it to rev much past 6-6.5k rpm might be more prudent to use a lower spec camshaft like a 270-275 degree with 10mm lift give you bit more low end and you won't be wasting top end with the smaller carbs a 282 is normally good for 8k but you'll need bike carbs with at least 38mm to produce power that high up.
as of right now my engine has 195k on it so i'm not really planning on reving much past 6500 anyway. And i have no plans of doing an extensive rebuilt. Probably just a refresh next winter. So if i can get a good tune of to 6.5k i'll be happy for now. We shall see. You might be right

You gotta put a how to thread on this. I was thinking about that for a while but some ppl told me that would be too much time, money, effort, and a waste. So what do you say???
more pics!!!!!
does it sound better?

whats wrong with JB weld? I bet that manifold will work just fine

Nice work. Have you thought about adding a support under the manifold to help support it, since the runners look long?
haha i bet there is less than $100 into this project so far... how much did you pay for the carbs and the aluminum?
see it doesnt have to be pretty to be functional
429whp 362wtq A20 TURBO. A20T>*
Sweetness, you have to do a dyno run with those... Great work.
so far for the setup on that car i'm right around 100 dollars. I paid like 40 shipped for the carbs and about 45 for the aluminum. But i have a bit of extra tubing. And i probably have 15 dollars into odds and ends. As of right now i can't really give a good opinion because I went from an awesome tune on a weber to a terrible tune. But hopefully this weekend i'll get that sorted out. I did drive it today which was sweet but hard to tell how it was actually gonna perform. I did think about running a support but i don't think i'll need it. The welds should be plenty strong to hold everything.

wow thats not bad! sweet buy maing!
that is pimp
and i love the color with the goldish rims it looks hot

i have to agree with Eric, you should consider support under those carbs. You can't just rely on welds. vibration and stress will crack them for sure.
Alex.
I might but a support under it at somepoint but right now i'm just trying to get it back on the road

A20, no balance shaft, even the sturdy factory manifold uses supports, that should be figured in the mixOriginally Posted by shepherd79
An idea to diguise any uglyness is foil furnace tape, just an idea. I used it on my adapter plates, I used epoxy around them to they dont tend to shake loose the plate screws, it looked bad but worked good, so I used a small strip of that foil all around the adapter plate after I trimmed off the goopped metal epoxy,it still looks nawigged, but better than goop.
That's great! I want to see dyno results now!
so when do you plan on dyno'ing it???
