who's got a weber on a sierra

Post by **NIK** » Sun Jul 15, 2007 6:01 pm

"Geez that will never run, it came off a 2 liter, its wayyyy to big"
Yep got that HEAPS I stopped going to a certain parts place as that was the constant attitude I got especially when I wanted bigger jets for it.
Finaly someone agrees with my theory on the float bowl

. Ive being doing lots more reaserchand this is what Ive come up with,
For aggresive off road float drop should be limited to 44.5mm max droop.
Float level for plastic float 35mm - 51mm
Float level for brass float 41mm - 51mm
The last to webers Ive had both had plastic floats so that means 35mm - 44mm should be the new settings.
So changing from the 41mm I currently have to 35mm would put more fuel in the bowl and help stop it from starving on hills, and the change from 51mm to 44 should keep more fuel in the bowl?? Just trying to get my head around it without having the carb infront of me

This weber is doing my head in, Ive just downloaded about 50 pages worth of info so hopefuly I can sort it out! I measured the depth of my bowl its 48mm deep so with the float set to 41- 51mm Im missing out on the last 3mm of the needle and seat opening so it would in effect be restricting the fuel flow.
My last post has me confused so you guys have no hope

The standard weber float setting for a plastic float is 35-51mm so thats higher then we are currently running the 41-51mm is for brass floats.
But I read that for extreme off road you should set the float to 44.5mm.
Im guessing that that is the upper level so you would have 44.5-51mm, so that leaves you with 6.5mm of fuel. But in my case my bowl seams shallower so I would only have3.5mm of fuel?
HELP

Go and get a plastic float . Ring rampage to get one in for you much better than a brass one

change your idle jet to a 45 from a 60 have you got a electric fuel pump if so run#.189lbs preassure

I already have a plastic float just wondering how it compares with others and the depth of there float bowls. I still have to get a regulator but Ive heard to runn 1 bar and Ive also heard to run 1psi which is it?
Thanks Nik

Im thinking about trying a weber on a g16a 1.6 8 valve, I cant afford efi at the moment, and the standard mikuni carb confuses the hell out of me.

Do you guys recon the 32/36 would suit the 1.6?

Im guessings that the adapter that B4T has got wont suit the 1.6?

Post by **NIK** » Mon Sep 03, 2007 7:50 pm

Im running the 32/36 on my 1600.
I would think the adapter would fit but I used my 1300 manifold as it was already ported.
Dont use a regulator! ive been emailing Sarge from midwest performance, unbelievable knowledge on these.
I use an electric pump then restrict the return line to about 1.5 mm that way you get fuel quickly without the restriction of the regulator, trust me heaps better this way.
The change to a weber is like going 1300 to 1600 all over again

As well as jets make sure you get/have f50 emulsion tubes as this is what weber recommends for suzuki engines, the f66 standard ones I have atm make it run rich at certain times in the rev range.
I highly recommend searching webers/ sarge on zuwarrie LOTS of info I have a "bible" of over 200pages now

Also if you dont go "swimming" get a ramflo filter it breathes heaps better.

Thanks boner, I just PM'd Nik.

B4T I might take you up on that offer, I have to get an exhaust fitted before I can drive it on the road, I'll let you know when/if I need some help.

EDIT: I type to slow, ignore the PM Nik you just answered all my questions

I had a bit of a search on zawahurrie (sp) but it seems that the vitara/sidekick in USA only came as EFI (in 8 and 16 valve) so I dont think I am going to find a whole heap of useful info for my setup

I just pulled the carby off my 1.6 and took a couple of pics of the intake manifold, from my (bad) memory it looks the same as a 1.3 carby mounting, but Im not sure what the 2 holes on the mounting surface closest to the engine are for, they look like water feeds to me, is this going to be a problem for using the weber?

Im gonna have to pull this intake manifold off anyway to do the port matching (if the adapter does fit) do you guys think I would be better off just using a complete 1.3 intake? (Im trying to work out all the parts I need before I get to far into this............... and I made the mistake of telling the boss what I was planning, now she wants to know how much Im "spending on that piece of shite this time")

Cheers

Post by **NIK** » Tue Sep 04, 2007 8:29 pm

Im struggling here

I think they are the same the holes would before the water choke and the adapter definately dosnt have these holes.
Im sure I bypassed the water jacket anyway as my standard carb choke was r/s! For the weber you wouldnt need this anyway if you run a choke. If your weber is set up properly you wont need a choke anyway mine starts first kick and I hold it at 1000rpm for maybe 10 seconds and then it idles (at about 500rpm but it DOES idle). I removed the choke blades as well to get more air in.
You must have missed the webers on 1600 posts on zuwharrie as there is a few and Sarge the guru himself runs a 1600 with a weber although his is a 36?? with a completely different bowl set up alot more offroad friendly BUT the are R A R E

The jets Im running are what was recommended for a 1600 a valve extractors and exhuast.

Is this one of the threads you were talking about Nik (I suck at searching)

I thought (before I started reading the above thread) that all vitara/sidekick in USA came out as EFI?

If you think one Weber is fun.... Look at this... http://cgi.ebay.com.au/suzuki-swift-gti ... dZViewItem
I don't think it's a bolt on !!!

Post by **NIK** » Wed Sep 05, 2007 8:57 pm

I must suck at searching as I dont have that thread in my weber "bible"
I THINK 1600 8v came out with carby then went to single point injection??
Trust me in terms of power bolting on the weber is like going from 1300 to 1600 again.

That dual weber manifold looks like it would be for sidedraught carbs, not sure but I think that would start getting costly as the 32/36 was a stock carb on some cars where as other webers are "performance" aftermarket carbs.

B4T is this the adapter that you used?

Post by **NIK** » Thu Sep 06, 2007 8:22 pm

I havnt used that one but id go the $30?? redline 1 as that same 2 hole pattern that is used on the weber adapter is ported out of the sierra manifold to 1 very large hole for better flow.

i have the same as you nik it works fine i might be going down a different track picking up a set of mic's of a gsxr 1000 soon then just got to make a manifold for them will keep you posted on how i go . boner

Post by **Jaffa** » Sat Sep 08, 2007 10:20 am

Just a little bit of info for anyone else trying to get an adapter, autobarn dont keep any redline adapters in stock anymore (sparco instead) but they can order it in for you, the redline part # is 10-220 $49.00 (95% sure thats the right one) or you can order the Lynx adapter here http://www.lynxcorp.com.au/shopping/default.asp under "carby adapters" "KC carby adapters" Part # KC112 $32.45 plus freight

Took the zook out on the weekend, drove some pretty hairy obsticles and Im alot happier with the set up at the moment. It ran great with it almost going over side ways and with th front end skywards on techinical stuff

. On very steep hills with a humps etc it would have a slight stumble. On the same hill going back down with the fuel pump turned off, using engine braking it ran fine but if you put the clutch in it would stall.
Overall alot happier than before and proply partly due to 1600 I could accelerate UP hills towing a trailer full of caming gear for 4 people!!

I decided to take the easy option, I got a sagified Weber and intake manifold of Ebay (in USA) it came with everything I needed except for an aircleaner.

My question is where to you guys that have a weber connect the charcoal canister to? The isnt any points on the carby itself and any that were on the manifold have been filled.

I looked in the sierra FSM and one point off the charcoal canister it supposed to go to the carby and one to the intake. The only "spare" point I have on the intake manifold is the vacuum for the brake booster (1ltr Non-Assisted booster) Would this connection be suitable (with a restrictor) for the intake connection.

Post by **built4thrashing** » Fri Sep 21, 2007 9:23 pm

just plug it. dont worry about the canister. its only for polution stuff and wont effect the way the car runs if left disconected. Prob not legal to do this but oh well

Post by **NIK** » Sat Sep 22, 2007 3:00 pm

You HAVE to give us notes on the sargified weber!! How is the bowl modded to prevent fuel spill. Id love to have a good look at it

Just had a look at the charcoal canister on mine and I have it connected to a port just below the adapter facing rearward if that helps any.

Finished fitting it up today, just gotta figure out an air cleaner that I can use with my snorkel.

Here are a couple of pics, if you want more, or more detailed ones let me know.

Post by **NIK** » Sat Sep 22, 2007 4:30 pm

That thing is a work of art

if/ when you pull the top of it Id REALLY appreciate some internal pics.
An idea for the airbox i saw somewhere use a vit?? efi air box. Cut the base so not as tall then use the airbox onto top of carby and use the tube that normally supplies air into the engine as the out to the snorkel. Hard to explain but webers go alot better with air coming straight in the top so with the airbox and a ramflo filter it should go well. Id do the same but I dont have a b/l fot the clearence.
Nik

Post by **Jaffa** » Sat Sep 22, 2007 6:13 pm

I'll take a few pics when I take the top off the carby for you Nik. Im going to Pick-a-Part tomorrow to search for an airbox that I can mod to fit.

The only things I had to do the the setup I got was grind a little off the intake manifold to clear the fuel pump, take out 1 bung on manifold (for temp switch for thermo) and put a different fitting on the carby fuel inlet.

If ya get stuck shoot me a PM.

Post by **lefthand** » Sat Sep 22, 2007 10:33 pm

looks good!! can't wait to see the finished install pics.

i just noticed that the water neck on the new intake is oriented 180* opposite of the water neck on the old intake. hmmmph.....i never realized that before.

good luck with the swap!

Post by **Jaffa** » Sun Sep 23, 2007 2:12 pm

G'day Lance - Im guessing sarge just put the water neck on that way when he sent it to you so it was a little smaller in the box, I just pulled it off (It wasn't siliconed on) and turned it round the other way.

For any one else who's putting a weber on and doesn't want to run a air filter on top of the carby, K and N make a "mini plenum" that will suit a 32/36 http://knfilters.com/search/product.aspx?Prod=85-8921 It probably isn't the best for air flow into the carb, but so long as it isn't too expensive Im going to give it a try.

Post by **NIK** » Sun Sep 23, 2007 2:46 pm

That looks like it would do the job. I think it will restrict air a bit but no more than running top mounted filter with a solid lid. I asked a few places for something like that and they all said no. If I decide to go swimming in anything above waist hight I,ll get one of those to adapt my snorkel.
Dont pull the cover of just for me but when you do pics PLEASE
