Finally got my weber 32/36 for e16, need help from someone who's done it before.

I know that there was a guy on here a couple years back that did the weber 32/36 conversion on his e16 pulsar.

Just wondering what he did, the one i got is a water choke, but stock is an electric choke, should it just be as easy as splitting the heater core line and run it through the carburetor?

Also any other tips anyone can give me are appreciated.

Thumbs up

I can help on this now
Finally finished my carb set up and all thats left is the throttle cable and super
fine tuning.

1st Step:
-Remove old carb.
-Be sure to disconnect anything that attaches onto the carb.
-That means fuel lines, vacuum lines, etc.
-Carefully disconnect the 2 cables on the throttle plate. (if u have a auto tranny)
-One is the kickdown cable and the other is your throttle cable. Leave em for now.
-Throw/burn old carb, but remember to remove the original throttle plate. THIS IS VERY IMPORTANT.
-Now, you have the 4 original mounting bolts. To remove em, use 2 of the original nuts
and spin them all the way down the bolts. Tighten the lower nut till you no longer can,
to the same with the top nut. Now, get to wrenches. Put one on the lower nut for loosing
then the other to hold the upper nut in place.
-Give 'er till the old threadlocker gives. Repeat 4 times.
-Carb gasket is now free game
-Now, clean the mounting surface and clean the intake manifold if you want, but it should be nice and shiny.
*I used a putty knife to clean it, worked awesome*

Now its time for Part 2!

I'll post more once I get back from work.

Part 2 is here!
Since I didn't take any pictures of the pre-assembly, I'll just have
to take a picture of the finished product and label all the stuff :P

Damn, the water choke model O_O"
You're gonna need the electric choke assembly otherwise, I'm sure,
you're gonna run into problems once you get to the tuning....

Haha, 7 times?! I gave up on the carb after it vapor locked on me in traffic
and having to tune it 10,000 times before then xO

Pre Install

Bascially, follow the instructions given to you by Weber of assembling the
adapter plates. What you are going to need is
-Threadlocker
-Permatex Form-a-Gasket (brown gooey stuff)
-Proper sized hex keys and wrenches

The last gasket can either by installed directly onto the adapter assembly
or on the carb. I choose the carb just to be safe.

Pre Install part 2

This part is for the carb. Looking at it, you'll notice that Weber wanted
you to have through the trouble of having to mutilate your throttle cables,
so it would work on the provided "new" throttle plate.

This part confused me of the longest time...
pretty much take off all the crap on the throttle assembly and throw on
the original throttle plate.

Universal carb my ass.

THIS IS ALSO VERY IMPORTANT!!!
You will notice that when you try to manually open the throttle, that the
"cable track shield" catches on the (i think) fast idle connection.
To solve this problem, I used 3 washers.
Webers provided washers do not work -_-" So you gotta pick up some.

Universal carb my ass, once again.
Be sure to check again to make sure nothing is catching.

Now its time for the electric choke connection.
In your case, jsanders....you don't have it yet so...read on
To back to the car and ,if you haven't already, disconnect the wires
which originally hooked up to the idle cutoff solenoid and electric choke.

Bascially cut off the idle cutoff solenoid at its connection, so u have tons of
wire to work with, do the same with the electic choke wire.

Now, for the electric choke, get yourself some saudering materials and
connect the wire to the plate on the new electric choke.
*if you have no clue what the hell i'm talking about, look at the "original"
electric choke connection metal plate....thing and copy what you see on the new choke.

Since I was hoping I wouldn't need the DGEV cutoff solenoid, I didn't order one -_-"
My hopes were crushed after hearing my car run and spatter abit after I finally got
it running and stuff. So I'm gonna have to order one now.

I'm hoping the install for the solenoid is the same as electric choke,
but its gonna be a bitch now since my carb is already installed -_-"
More on this once I get it...

Part 3!
Installing the carb!

Once again, follow the instruction provided by Weber, and all should be well.

ANOTHER SUPER IMPORTANT THING YOU NEED TO DO!
Plug all lines you do not need with superglue!
This includes the fuel return line, the canister line, all the feedback lines etc.
Just be sure not to superglue shut the vaccum advance line.
Don't disconect the distrubtor lines, it'll still run fine if you leave it hooked up the
way it was left.

Secondly, now for the hot air injection line and the white thingy located at the back
of the engine...(the thing that plugged into back of the original carb pan)
I plugged these using superglue and cardboard.
Yea I know it sounds stupid and looks like it too, but so far I've had no problems with this.
Ran the car for a good 30 minutes and all the plugged lines stayed plugged.

Now that the new sexy carb is sitting on the new gaskets, bolt it down.
Make sure the throttle plate is in the right place.

Since Weber is a complete group of morons, they forgot to send me the new fuel
hose. The correct size is 5/16".
2 feet is more then enough and leaves lots of slack.
Remove the original fuel hose for the fuel pump.
Make sure you're removing the delivery line, not the fuel filter line.
Clamp down both ends nice and tight.
Connect the electric choke and idle cutoff back.
Now you're ready for some fun.

Grab your bud and every carbs friend, Carb cleaner. (or gas if you feel dangerous)
Spray/tons of carb cleaner/gas into the new carb. I shouldn't have to get
to technical about this part so..yea.

Now have your friend give her!
BAM! the car should be running now! Whoop whoop!
Just remember to make sure the car doesn't stall out by spraying some
cleaner/gas into the carb to keep her alive.

Wait for the car to warm up to optimal running temp and
read the instructions provided from Weber to tune the carb.
*I had to tune mine without a working tach...it sucks...ALOT*

After you finish that part, connect the kickdown cable to throttle plate
and check the idle for all gears and set to factory settings if needed.
This is obviously only if you have a auto.
Connect the air cleaner, etc. and check everyting again.

Thats about it, the car should be running fine and dandy.

The last problem I have to solve is how to hook up the gas pedal cable to
the new carb....as the "universal" cable holder thing doesn't want to hook
up the to back of the carb...probably have to sauder it directly to the carb I think.

Pretty much you want the gas cable to be in the exact same way it was on the
original carb. More on that once I get the time to solve it.

Wish my tach was working........*sigh* Really makes tuning the new carb
a bitch lol. Any questions will be promptly answered, and good luck!

I am so proud of myself, did all this myself =)
Best DIY project ever, plus I learned a shit load of stuff too.
I have a feeling this carb is going to spin the tires abit when I can floor it ^___^

i'm gonna splice the input line to the heatercore and run it to the in line on the carb, and splice the output line from the heater core and run it to the out line in the carb.

after getting all the float settings right, the damn thing didn't idle and still ran rich, but ran well enough to get me through the summer. jets were old and blocked, etc

didn't u say before that if i took the throttle plate off the hitachi it bolts up perfect to the weber? didn't think that was a good idea because the barrels on the weber are bigger than the hitachi, creating a loss of power. i'm just gonna make an adapter on my milling machine.

More on this once I get it...
after i ripped out my cutoff solenoid, it would only "diesel" (run on after shutoff) if the idle was high, like about 1200RPM, i'll get the weber down to 800RPM where its suppost to be.

only lines the canadian model has is vaccum advance and vapor canister. only line running from the dizzy is vaccum advance. don'tcha love emission devices here? basically zip compared to what you have. makes the engine compartment look really clean

anyway people just usually remove the canister alltogether and put a k&n valve cover filter there from the tank. works fine and looks stock!

won't have hot air injection, got a set of headers. only thing is egr, which i'll keep hooked up to prevent pinging at high acceleration.

white thingy is anti-backfire valve. i'll just plug it on the intake manifold, but it does prevent after burning in the exhaust system at the initial period of deceleration. EGR should take care of that!

cars gonna have to run at 2000RPM for half an hour to break in, so gas pedal will be held. This will be the first run too.

nice, now what you do is get a garbage can, put the crap hitachi carb in with a propane tank, get a shotgun, stand 200 ft away and shoot it. good way to burn the old carb, as it was burning my gas away!

I think I used the wrong terms >_>
Ok on the Hitachi carb, on the end of the throttle assembly, at the end of it you have
that weird looking piece of metal which has two cable hook into it.
Thats the piece you use to for the new carbs throttle assembly.
So theres no need to make a special "plate" as the hitachi one fits fine.

Wish I had my camera...would really clear things up.

K&N Valve Cover Filter....what do those look like?
(Just got bored and removed the canister too lol.)
Also, where is the EGR valve located? On the driver side of the engine?
Stupid book doesn't tell me where it is, gotta check it before I forget.

Going to be using coolant to control the choke? Whoa, never woulda thought of that.
Meh, still prefer electrical =)

I just plan on keeping my car stock-ish. Next project car is gonna be sleeper...
1992 Sentra coupe, bone stock, powered by a JDM SR20DET and matching manual tranny =)
Well, I can only hope.

try this:

K&N Crankcase Vent Filters

doesn't have to be k&n, can be anyone. he also made up a bracket to it (guess it would be similar to the bracket that holds the coil in)

Quote:

well its not even needed! it can also cause problems if it gets saturated. usually thats what people would do on older cars cause they never worked right anyway.

it runs from the exuahst manifold to the drivers side. has nothing to do with the carb conversion though. you'll notice theres two tubes running from the manifold. the AIV is the one you blocked off.

Quote:

sometimes with electrical, if you have the ignition on before you start the car, say to listen to the radio or something, or to shine light with headlights (both not a good idea if ur running battery power), the choke will open by itself with electricitiy after a couple of minutes, possibly making it hard to start the car, cause the heater will have already gotten hot and the car will be really hard to start. heard about this on the datsun1200 club.

Well, if you get a K&N Crackcase filter, be sure to tell me what item # it is
Shouldn't run anything if the car alternator isn't running anyways, thats my rule of thumb.


I'm really having troubles solving this dieseling without a cutoff solenoid...stupid tach. -_-"

try to get your idle speed as low as possible, its possibly running too rich at idle. if you set it up right you shouldn't need a cutoff solenoid.

if that doesn't work you could try shutting it off in gear

Haha, sorry been really busy with school and my car :O
Installing new carpet is a bitch, not to mention totally re-doing my trunk as well.

Carb is pretty much almost done tuning, its still alittle pissy. Just a couple of sessions
and she'll be done.

Oh, what should i do about the line which hooked up to the charcoal canister? Plug it or leave it? (until i get the K&N to replace it)

dunno if it'll make a difference. plug it, it may keep the tank pressurized.
