I've been offered a pair of twin Dellorto DHLA 40E carburettors and I'm wondering how suitable they would be for a 2 litre Pinto.

They don't come with a manifold so that would have to be something else I'd have to source. As well as getting them rejetted etc.

Can anyone help me?

They will fit & run on a 2.0 pinto, with the right jets, but 45's would be better.

enjoy

They will be absolutely ideal for a Pinto in standard to moderate states of tune (up to about 140 bhp).
A lot of folk say Dellorto's are also preferable for road use too.
45's are only needed if you plan to cross the 140 bhp (ish) threshhold. Keeping to slightly smaller carbs will in theory give you superior driveablity with a negligable loss in power (if at all) with the right jetting. In reality, you will be 'driving' it more than you will be holding it flat out....
However, if your intention is to build a 'hot' motor, go for 45's it is only then that the superior breathing capabilitys pay off with the larger carbs.

HTH Stu.

Thanks for your help, the engine is standard so it sounds like they'll be worth having.

I need some carbs now that I've decided against fitting the EFI gubbins, so I think I know where I'm headed!

Try Dave Andrews' site for some insight into the jetting and choke sizes etc. They are supposed to give better fuel atomization than Weber and can be jetted for top end or middle, he has a jetting prog that runs in a dos box and gives a starting point for you to work from.

yours, Pete.

Thanks again,
I have now discovered that they don't have a manifold, so they may not be the bargain I was led to believe!
Cheers

£90!! You jammy get!! Mind you, back when I was planning to use a Fiat twin cam I got a pair for £100 so I can't talk
I'm now contantly scouting for an old pair to turn into throttle bodies, but that won't be until I fit the tweaked engine...........



(Note to self: Get the bl00dy thing on the road first, then worry about tweaked engines & throttle bodies!)

This any good? (Will prob wrap)

No connection etc...

Those would be Webers, the Dellorto are DHLA most likely.

yours, Pete.

Weber DCOE and Dellorto DHLA both use the same manifolds.

Cheers,
Matt.

The Dellorto one looks like this

Sorry Ben, I don't know why I repeated myself about the manifold, repeated myself, repeated myself

I've now been looking on ebay and there are plenty on there for far less than the pair I was offered. Some of them look a lot cleaner too.

I was thinking of including a rebuild kit in my budget when looking, or should I just try them first?

Sorry Matt, didn't know that. I picked this one up with carbs for £100 and haven't got round to fitting it yet. I think it's a shorter one than the one on ebay. It needs a spacer gasket between the carbs and manifold face and I've not seen one. Now I know that it uses the weber one I might get interested again.

cheers, Pete.

Wow... there's quite a few inlet manifolds on Ebay... even found one i need .... Vauxhall 16v to twin 45's

But no money at moment

Pete - I spent ages looking for a Dellorto manifold too before finding out they were the same as Webers!!

The manifold I'm using for my DHLAs is so thin it doesn't even have 'tubes', it's just a 1 inch thick piece of ally with holes bored through at the appropriate angles - carbs fit in with tons of room to spare for filters. £65 from Burton Power. Bought it new because I got fed up of being outbid in the last second on Ebay :-)

The things that go between the manifold and carbs should be plastic spacers with a grove on each face in which fits an o-ring. The carbs should be bolted on using springy washers so that they are free to move slightly relative to the manifold. Not sure why this is though!

Cheers,
Matt.

Anything like this you mean

oh and its metal, with rubber o-ring either side of it ?!?!?!

They arent the best type to use, neither are the 'springy' washers. The best type are called "Misab" gaskets, which are a thin steel gasket with one rubber O ring cast onto it. These should be used in conjunction with rubber bobbins and cup washers to mount the carbs.
The type with the two O rings have a nasty habit of spitting the O rings out (or sucking them in!) if the engine backfires. Also the 'springy' washers sometimes snap. thus releiving the clamping pressure on the carb to manifold, and sometimes giving rise to the first mentioned problem.....
