New Weber Carb - Will it fit..??

Postby D366Y » Wed Jul 12, 2017 9:23 pm

Sorry if this is a bit too stupid but wanted to check before I go forking out cash by checking with you knowledgeable lot on here!

I currently have (what I think is) a Weber 34 IHCand want to upgrade to twin carbs on my 1.6 so there is a bit more oooommpphh and makes a nicer intake noise too haha.

I was looking at Weber 32/36 DGAS and found this on ebay:

http://www.ebay.co.uk/itm/WEBER-32-36-D ... 1438.l2649

My question is that it doesn't actually say anywhere it suits a 1.6 but will suit 2.0 and they are basically identical but wanted to ask first! :lol:
Am I also right to assume that the manifold I have for the single carb will not be compatible with a new twin carb and therefore will need a new manifold too?

Thanks in advance guys!
Danny

Hi Danny

It will liven up the 1.6 considerably, especially if you put a 2.0 camshaft in. Unfortunately you will have to get the 2.0 manifold as well as the throttle linkage and it may need slightly jetting down so that it doesn't run too rich. The sellers may be able to advise you on that point.

Long time no see.

Paul.

You wanted to upgrade to twin carbs.......32/36 is not twin carbs....it's a single, twin choke (progressive) carb.

Yes, with the manifold and linkage it will fit the 1.6. They do not normally need re-jetting unless you are doing other mods as well.

You will end up with the next best thing to a 1.6 S/ 1.6 GT, an engine that Ford should not have discontinued.

The standard 1.6 came with a manifold for a single choke carb . it has a single round hole for the carb & 2 studs

Whereas the 2 litre and the 1.6 GT had a manifold for a twin choke weber has a larger opening for the carb and 4 studs. It will take either a 32/36 or a 38/38 but personally I would stick to a 32/36: Here is one http://www.ebay.co.uk/itm/Ford-SIERRA-C ... SwGBtZYXZl

BUT rather than Ebay, better still, why not check with Martin @CapriGear & Nial Diamond etc whether they have a good and serviceable 2 litre carb and inlet manifold they can sell you as this will be cheaper than buying new. Im sure they would also be able to dig out an original 2 litre air filter if you wanted to keep things looking standard - otherwise a good old K & N always looks good and makes a nice induction noise.

As has been said, it is quite likely that a carb from a 2 litre Capri will work quite well on your 1.6 without changing the jets. BUT for the frankly tiny amount of time and money involved I would suggest checking the recommended jet sizes for the 1.6 against that of the 2.0 and changing where these differ- make sure you check for 1.6 Pinto NOT 1.6 Kent/ohv or CVH engines as they will be different. The information on jet sizes is easy to find and the jets are easy to get hold of from Ebay and other places. Youtube will show how to get to the jets to change them. its all very easy peasy.

The 32/36 carb will have 2 each of these types of jets;
Idle
Mains
Air correction
emulsion tubes.

Thanks for the replies guys, and apologies if I got my terminology wrong;

I already have a twin choke manifold kicking around so just need the carb and any linkages as well. I was tempted to get a used serviceable one but at the same time if I can get it brand new looking shiny it is pretty tempting... Nevertheless I will ask and see the difference.

I would suggest checking the recommended jet sizes for the 1.6 against that of the 2.0 and changing where these differ- make sure you check for 1.6 Pinto NOT 1.6 Kent/ohv or CVH engines as they will be different.

Thanks for this advice too, I've never really fiddled with the carb before so this is largely mumbo jumbo to me but time to educate myself I think!

I asked the seller of the initial link I posted if it would work and they directed me to the same carb that would work with the 1.6 which is all good, but I want to improve the performance without dropping a 2.0 engine in it; I already own a 2.0 I can't afford to insure so this is the easier alternative!

I really wouldn't recommend you bother changing any jets yourself for ones that you find specified on the internet. Here's why.....if you assume the current jets are not exactly right for your engine, you change for spec ones. These are specc'ed for a brand new engine in tip top condition, which yours is not. So therefore your new jets are unlikely to be exactly right so your gain is nothing. If you are going to tune your engine, once you have done all the mods THEN take your car to a rolling road and have the jetting done professionally and matched to your engine specs.

You can get excellent results just by doing a good top end overhaul and fitting a 2 litre cam. This is the engine I built for Dan the Capri fan on here and that will skin a std 1.6 easily we tried it. And that runs a 32/36 from a 2ltr with no jets changed.

This is sound advice Danny, there is a rolling road tuning place in Slough I think.

On a standard 1.6 Pinto putting in a 2.0 Cam or a Fast road cam, coupled to a 32/36 with good jetting, and a good exhaust and ignition system should give it considerably more pep.

I bought that very carb from fastroadcar when upgrading my mates cortina 1.6, the jetting suited it and gave it a bit more pep in comparison to how it was after i set it up

Don't forget with that one you will need to add a choke cable as it's manual choke

Great stuff guys thanks or the info; The only sort of thing I can find is either Piper Road cams or something like the below

http://www.ebay.co.uk/itm/Camshaft-Foll ... SwVFlUDvgW

Piper cams are like twice the price and then some which seems pretty pricey just squeeze some extra power rather than trying to make a race spec road worthy 1.6...

I have a sportex exhaust and traditional points currently, tempted to go electronic if pumping the power up a bit anyway but not a guarantee yet.

Judging from everyone's responses, plan is to now get a 2.0 cam if they are around 75-90 quid and then get the twin choke carbs and rolling road it and that sounds like enough wages for one day spent :lol:

If you guys agree that is the best steps I will go ahead and start splashing the cash!

Danny

A bog standard 2.0 cam is what the 1.6 S had and would be cheaper than a Piper or Kent cam and give known and predictable results. Don't want to put you off if you want to go for a quicker cam but if you do decide to go that route I'd suggest going for a fairly mild profile with a low to medium lift but long duration. Using a very high performance fast road/ race 2.0 camshaft in a 1.6 enters less known territory and some would also require specific followers and valve springs which knocks the price up .

That's ideal, exactly what I needed to know thanks!

I don't want to try and squeeze stupid ridiculous amounts of power out of the engine, just a little more to have some more fun!

On this basis, I'll get the standard 2.0 cam rather than a piper or Kent as these are like double the price :shock: so will have that fitted then get the twin choke webers, then rolling road then should be all good??

Brakes I guess would be the next upgrade so will order some new pads as well to make sure I can stop still :lol:

Thanks for your help guys, if I have missed anything or you think something else should be done too, please let me know so I can do a proper job once :)

New decent quality brake pads are always good and frankly can often feel like a serious brake upgrade if the old pads were a cheap unknown brand or badly worn. Its worth checking for recommendation of brands on the forum. As you probably know its always worth checking the state of the discs when you change the pads and ordering replacements if they show deep grooves or are starting to look a bit coke bottle shaped.
They aren't expensive (especially if you get perfect 2nd hand ones from one of the usual vendors, Martin, Niall etc) and will save you money by not having to replace pads as often.
