Weber kit on a Brumby

scissorspaperrock · Post by **scissorspaperrock** » Mon Jul 09, 2012 4:48 pm

Just a run down, parents have a 92 Subaru brumby, that is mainly used as the farm vehicle, (To put wood in, and then bring it back to the primary house)

A couple of times a year its taken on slightly longer trips, down the coast with the Golf Clubs etc etc,

As i have no idea on Carby's could someone give me advise, on whether this will work, and if there will be any implications

NEW WEBER 32/36 DGAV ELECTRIC CHOKE CARBY CARB CONVERSION KIT SUBARU BRUMBY 4x4
http://www.ebay.com.au/itm/NEW-WEBER-32 ... 3f165e729c

A tiny bit more power would be nice, so air-con, is able to run when its going up a hill :P

Also anyone know where i could find an aftermarket exhaust (not a sports exhaust) as we seem to be replacing it each 2 years (guessing from cold start ups etc etc, its 20 years old with only 92,000 on the clock)

Any help would be appreciated,

stainless exhaust from your local exhaust shop will be the ticket

$835?

Same kit from the USA:

http://www.ebay.com.au/itm/Subaru-1976- ... 4cff480899

Except the adaptor plate is for EA71 1600 only.

Post by **TOONGA** » Mon Jul 09, 2012 6:04 pm

the American kit is for the EA71 and the EA81

"Subaru 1976-1989 1600/1800 OHV EA71/81 Weber Carb Kit"

Even if the adapter plate was wrong, Auto one sells them for 60 dollars and you would still be at least 300 dollars in front.

there are quite a few cheaper than the GEMS kit with the American one being the cheapest

The first one linked, says not for brumbies 85>

This will NOT fit the 85-on Subaru OHC 1.8 engines that were fuel injected (port or throttle body)

Though on that note, i think they are referring to the ea82, where the brumby would have an ea81 ?

To be honest as well, cost isnt a big issue, reliability, and hassel free experience, would be worth an extra $500.

Also, how much extra peformance would one expect, i realise the brumby is never going to win a drag race, just looking for a tiny bit more ooph in the mountains, or for overtaking.

Will modifying the vehicle like this require
# Engineers Report ?
# is it emission legal ?

Or likely to create a less reliable vehicle ?

Cheers

DGAV is a water choke.
DGEV is an electric choke.
DGV is manual choke.

When you talk Brumbies at any place other than here, the dealer , most parts books think Brumbies stopped in 84 or they have EA82 OHC engines

You'll get used to asking for bits to suit an 84 Brumby to save them selling you stuff that won't fit. Carbs between L Series EA82 and Brumbies etc MY have been swapped between models without too much trouble. That italiced bit refers to mpfi EA82

It may upset RTA dudes or their business partners / inspectors if you don't have all the PCV hoses hooked up correctly and the charcoal cannister lines etc.

Being a ute - may be a little easier than passenger vehicle

That's a good point Steptoe. I assume that the weber would have to be a straight swap and all PCV hoses would have a place. We are lucky in the west, we don't have to have annual inspections. I can't see putting a Weber on would be breaking any laws. I'd be going for the one in the U.S for my 83, that's a BIG saving over the ones on ebay here.
By the way, is anyone out there running a Weber, if so what's your opinion.

Or buy a second hand one and put a rebuild kit threw it if it needs.
Straight bolt on with adapter.
The PVC and emissions stuff won't go on like the hitachi's I am told.

Gets me how the U.S can sell everything so cheap, we get ripped off big time.

steptoe · Post by **steptoe** » Tue Jul 10, 2012 9:08 am

I've got one waiting in the wings - came off an MGBsame cc's. They are not a straight swap as in just bolt up between manifold and air filter housing without adapter plate and mods to fit original air filter box - seen pics in here of modded box - that way all hoses for pollution hook up and no unsuspecting inspection will pick it. And for what its worth, a rally dude once told me his twins and his one Weber were very similar in power and thought it not worth the search for twins. It is common for weber converts to mention a thirst though Tweety seems to be content, but he's a trike

Where does it say that it won't fit Brumbies?

A Brat is the US version of a Brumby.

The kit doesn't fit any OHC engine.

EA81 is OHV.

IMO, I think it's the best thing you could do to a standard Brumby. It gives them the extra power to get up hills, power to safely over take trucks on the open road and makes a huge difference to the performance when the back is loaded. I would go out on a limb and say power is increased by 30-40%

As for regulations, you'll need to check with the licence dept in your state but in WA you require a modification permit but not an engineers report.

As for emissions, as long as you connect all your breather pipes back up then there is no legal issue with fitting a weber (again in WA so check your state regs)

As for reliability, I'd say it's really no difference, as long as it's tuned correctly and checked during every service (like you'd do for the standard carby).

BTW, Hi and welcome to AUSubaru

Cheers,
Paul

30 to 40% !! That is some limb ! Gees, a dyno test before (with a crapped out old Hitachi) V's new Weber would help sales

Brumby Kid · Post by **Brumby Kid** » Wed Jul 11, 2012 6:09 pm

How much does a dyno tune cost?
I'm ment to get one when everything's finished when the webers on.
But as we are putting the hitachi on first to make sure it works, if it's cheap, ( or I get sponsored) il do a before and after dyno.
I will also have 0.8mm iridiums. A sports exhaust inc headers, and obviously the engine.

Cheers Cam

Have you seen my limbs?

:D:D

Dyno runs would definitely show the real truth but as I stated, it's IMO and many of the cars I've done for people, they all can't believe the difference.

$500 to $1000 depending on the time spent on the dyno.

A single dyno run just to log horsepower can be had for less than $150 in some places.

Wish those shops would start up over here in the West

Remember I run an auto vW tranmission. Even so the weber did achieve a best mpg of 34 cruising. Common was 27. This was with iridium plugs, MSD blaster 2 coil and 8.8mm red leads.

Also trikes are exempt from anti pollution stuff. so it all got blocked off or discarded. Trikes arent great on aerodynamics either.

I'd recommend the weber carb conversion. Personally if I had a brumbey and could modify the standard air filter body to retain it I'd do do. Dont thing many sports air filter set ups increase power much anyway.
