Just wondering if this would even be possible?

I got the idea from the older 911's that had the two weber (triples) on each side of the engine and they make that engine sound so freakin cool. I know there would have to be a custom intake manifold made up. But would there be an interference with the electrical system or ecu by deleting the CIS system?

Interested to hear your input.

You think the CIS-E is problematic ...try to live with Webers..

My experience is with a 1966 Aston Martin DB-6 Vantage spec race engine with triple Weber 45DCOE's...

Great for a racing engine, but not so good for a street car.
No thermostatic controlled choke, they use an enrichment lever to start.
The Weber intake bells on the DB-6 fit into a sheet metal airbox with a drain in it...
The drain is in the box to let the raw gas flow out on startup.
Did I mention the flame arrestors which snuff out the fires on startup?

It's difficult to maintain an idle until the engine comes up to operating temp and you can cut off the enrichment circuit.
Until then black smoke from the tail pipes !!!

Not to mention keeping them balanced as each carb feeds two cylinders...
Almost as quirky as balancing triple SU's on a 3.8L Jag using a stethoscope...

haha well that certainly puts that idea to rest. I was also thinking of doubles on a m102 set up similar to a vw, but I think it would just end up being more of a hassle. Probably more productive to look into an ITB setup with stand alone management.

If you want a horny sounding m103, you could use individual motorbike carbs from a honda fireblade or yamaha r1. There have been a few cosworth 190's converted this way and they sound awesome!
We have a company over here called "Bogg brothers" who will custom build a aluminium manifold to mate bike carbs to any engine you like, and bike carbs dont go out of tune like normal carbs.

Easy conversion on the cis-e cars but not on hfm.

i had twin 40 dcoe webbers on a 1760 xflow ohv ford engine in an xpack fiesta back in the day... sounded amazing, wish i could find the pics of that car, it was a hoot.

as ed says, they were a pita to live with on a road car.

It won't interfere with the CIS electrics if you remove the Kjet fuel meter housing, fuel distributor and injectors. You will get a CEL but your ignition, instrument cluster and cruise control will still work. That said, go EFI or go home.

This pretty interesting, do you have any links of those cars online?

How can the r1 carbs flow enough fuel for a m102, which is around 2000cc and the r1 is only 1000cc?

Because an R1 makes something like 180hp and revs over 10000rpm. So it needs significant fuel and air flow.

touche.

Do a internet search for "bogg brothers" and go to gallery pages, some intresting pictures there for you.

Then look on youtube, all sort of converted cars on there including a rather legendry mk1 golf.

For what it is worth here is a write-up we did a few years ago on Webers. Basically not cost effective to do correctly, ie not worth the effort.

^ as usual, that is a well worded and factual report by a real expert.

good to note his comment about the std merc ignition being useless for finding power by tuning, and that obviously applies to an efi convertion, tuning spark is the way to find power above the 315-330 celing that the merc tt will make, because feuling is only half the story.

and attaking my spelling wont change that fact...

"some mods improve your car and make it into something it never was, other mods, however, although essentially the same, are not, and make that car a ricer"

if your car isnt shiny, you dont know what you are talking about, remember; paint shine = knowledge. In order to be taken seriously, you should spend all your money on paint, (and get a dyno reading).
Dont forget to polish it often

I've lived with Dual Weber 44's on a daily driven Volkswagen. Triple Webers would make me wanna shoot myself. EFI > Carb for anything newer than 1985, unless you want to do it just to do it.

Surely you don't mean Mikuni's. I've been through many on my Yamaha WR450, Suzuki DR350, Honda CR125R and others. They're pure rubbish, and the way they leak, always have a fire extinguisher handy!

The yamaha r1 or honda fireblade carbs are the most commonly used for these conversions, but you can use any bike carbs you like so long as you can get them jetted correctly.
