Just checking some alternatives out on ebay.

Seeing alot of Dellorto Twin 40 DHLA Side draught carbs for good prices.

however, they are all slightly different, "type L" "Type F", "Red top" , does this need to be taken into account ?

or will any pair of 40 DHLA's fit ?

Thanks Nick

no i just need to send my dad round with the money.

however, they're ?300 for the set with a square port 1.4SR manifold which is really no use for me ? Plus they don't look nice and shiney lol

just checking out some alternatives on Ebay before i go cough up my cash.

Some with trumpets, reconditioned, nice and spangly new for ?99.99 !

Also a set of Twin 40 DHLA side draughts, from an Alfa GTV 1750, look like new, only 180 dollars.

don't know whether they will be ok tho....

180 dollars? I'm not sure i'd buy american tbh mate-mainly due to being damaged when in courior and you might find parts more difficult to get, although i would imagine they're the same :?:

I think ?300 is over-priced tbh, i think you could get them cheaper than that. I nearly bought some dellorto's on ebay aswell, they seem quite cheap and are newer. If you hold on for abit longer i think you'll get a better deal.

oh it's ?300 for.

DHLA Carbs
Throttle linkages, and cables
1.4SR squareport Manifold
Twin K&N filters
Alternator bracket + Shorter belt
All gaskets, bolts e.t.c
a bunch of bits n bobs (spares)
and a Fuel King Pressure Regulator.

is that a better sounding deal ?

I need to change the manifold (as it's really a 1.4SR one), as apparently they were used on a 1.6 ? so i'm not sure if the carbs are jetted for a 1.6 either.

And i've only got kinda camera phone quality pics (the original Ebay link the guy bought em off has expired and the pics have gone)

I've asked for some better quality pics

That's not too bad, but still not deal of the century. If he used them on a 1.6 with that manifold he would have been wasting a lot of potential power. Also, does he have trumpets? Because i bought k&n's for mine and then got trumpets and the trumpets won't fit with the k&n's. You will need trumpets aswell for maximum performance and sound quality :lol:

lol the trumpets go in place of the K&N's.

it's the whole lot, but reading the original ebay link, the guy says they will fit a 1.4SR.

so i dunno... i may end up with a 1.4SR engine anyways now (insurance) and if i did that, i'd ditch the head and get a SRi one, same as the gsi head i think. So anyway, i need a round port inlet :-)

the trumpets do NOT go in place of the k+n filters. carbs need the trumpets to deliver good power, and i am sure they help hold the chokes in......

you have k+n filters over the trumpets.

i got my dellorto 45s for 280 with a facet red top fuel pump, piperX sox filters, and were fully reconditioned with spare gaskets, and had most of the linkage parts chromed,

40s without a manifold second hand are normally about 80 to 100 quid, then a manifold second hand is 50ish with the alternator bracket. and finally the linkage if not with the carbs will only be 50-60 new.

still cheaper than your looking at for the wrong manifold and carbs without trumpets

oh right, thanks for that M.D

that's another thing they probably don't have ! not looking promising now

good trupmets will set you back about ?60 for a new set of 4.

Nick
25-01-05, 11:07 PM
right, is there any performance/sound change with shorter or longer trumpets ? and are the ends a set diameter ?

ive been told by several people and engine tuners that longer trumpets give high end bhp increaces and short ones give better torque figures. not sure how but there must be some truth there somewhere for so many people to have said it.

personally id just get the trumpets you can that will not foul the bulkhead of the car, (only really a problem on 16v engines)

its the other way round mate.

longer ones will give you more pull low down the rev's and shorter ones will give more up top.

But you won't really notice any difference on a road car.

30-50mm is fine. If u can't fit them then fit smaller ones, but make sure you got some on.

Thought i'd chuck my tuppence in due to being right royally fucked about. The carbs nick has been planning to buy of me are mine, and no they arent "shiny" (after all that makes a hell of a difference in a 15 yr old or whatever Nova engine bay) but yes they are fully reconditioned and yes they are jetted for a 1600. Also a mate of mine who is a Vauxhall Tech said the manifold is suitable for any 8v lump??? I'm a bit dubious myself as to how correct that is but the guy who i bought them of had been running them on a 1.6 no bother. The filters arent K&N, they are Mangoletsi along with the manifold and linkages, and as someone rightly said they will fit over trumpets. Would you like to see the state of your pistons after a few months sucking in grit and dirt??? Well anyway after being told "yes i'll definately have em" for the past month he is no longer interested and wont reply to my emails. If anyone wants em ?200 the lot. Ty.

yes i was planning to buy them from you.

however, there were some slight discrepencies in your product description.

i.e The inlet manifold is not a 1.6/1.4 SRi Round port inlet, it's a Square Port 1.4 SR inlet.

A new inlet costs me ?138 + vat

And the lack of the trumpets, and the fact that they aren't jetted, and ontop of that the lack of Clear (not camera phone) pictures is not worth the ?300 you wanted for them

you have never sent me any emails, and since i sent you a mesage saying that ?300 is too much money for carbs without the trumpets, not jetted, and the wrong inlet i havn't had a reply.

1)There where no discrepancies in my description of the items, i stated that the carbs have been taken straight of a 1.6 GTE previously, i didnt at any point say what manifold it was, just that it was a "manifold previously used on a GTE".

2)
yes they are jetted for a 1600 As i have mentioned aa few times now, and is also mentioned in the Ebay link i sent you.

3)I stated photos would be ready for today as i dont have a digi camera and needed to borrow one..

4)Not ONCE did i ever mention trumpets would be included, you want a Nova chucked in as well?????

5)I completely agree that ?300 is alot for unsuitable parts, i recommend in future that you check what you need before asking someone to put things by for you. By the way, fancy taking a VTEC controller of my hands? Maybe a dump valve? See my point.

Anyway enough time has been wasted on you now, as i said previous post, ?200 or offers if anyone else on here (with the correct engine) wants them. I will stress though the carbs arent suitable for Go-peds, Buses or Briggs and Stratton Lawnmowers, just to save confusion. 8) And NO they dont come with direct port nitrous injection, lanch controlo or winning lottery tickets.

Cheers.
