    Hi,

    This will be my first post on the Kombiclub forum.

    I'm doing my homework before jumping in to buy a Type 2/Bay campervan, ideally a later model 1800cc or 2000cc.

    I need a new project to work on as I've recent finished restoring a 1968 Alfa Romeo... see attached image. So, I'd prefer a VW van that needs a bit of rust removal/body work, an interior fix up and perhaps a transmission and engine in need of reconditioning.

    I don't intend to go crazy with modifications, but I'm curious about the benefits (or otherwise) of converting the stock VW carb set up to an aftermarket EFI set up.

    I'm not looking for tyre-shredding performance, just "twist-the-key-and-it-starts" reliability, maybe slightly better fuel economy and improved day-to-day user friendliness. Are those realistic goals for an EFI conversion on a VW aircooled engine, or is the time and expense of an EFI conversion a case of overkill?

    To be absolutely honest, the Alfa has twin Weber DCOE carbs... so I'm not really keen on a second drama queen in the garage who regularly needs her induction system tweaked. I'm hoping EFI on a VW might address that problem.

    Are there any specialist EFI kit suppliers or conversion workshops in the Melbourne area that I should contact? Any indications on expected pricing would also be very helpful.

    Regards,

    Thats a very nice Alpa - can only imagine what you can do with a tired volksie. Carbs vs EFI, OK I'll be the first. I have an '82 EFI and replaced the original and very tired worn out L-jet EFI with a Haltech full sequential injection 4 coil over plug ignition system. Now its not a tyre burning upgrade but will lift RWHP from a stock 50 odd to 70 plus and reduce fuel consumption by some 10%. I added a cam and 8.5:1 compression and full balance to get 82 RWHP and a very smooth easy to live with bus. I'm happy. Also had a 72 Beetle in a previous life running twin dual throat Webber's and stuff and got tired of the summer to winter to summer tune ups. Now I just turn the key and drive - and it does want to run, just loves country roads, hills and the freeway. Depends what you want, others will rightfully champion original stock twin carbs coz they work. Can't comment on Melbourne shops - I'm Sydney focused and cost will depend on the shopping list from 1 to several thousands.

    Nice Alfa.

    Welcome.
    Want something needing a bit of bodywork, interior, motor n gbox reco???.

    You have landed in paradise.
    But dont say you didnt ask. ;)

    No fear of tyre shredding on takeoff either unless you do some major mods.

    Comments in above post is the best answer to you main qn at reasonable cost.
    If you want to fiddle then a suby 5 speed and 2.5 might get your interest.

    Yep. Nicely presented Alfa.

    You would have a bit of experience with that I assume :)

    anyway - g'day and welcome

    Yes - what AC-T3 said
    A few $k's but worth it if its to be a keeper.

    I use to have a beetle with twin Dellorto's and as much as I loved the performance and sound, having a car live outside I got very handy at clearing blocked jets and water getting in

    My T3 is click and go

    Hi Rob, cbus & David,

    Thanks for the welcome and comments on my Alfa... I suspect that rust is a common enemy of both Alfa Romeo and VW Kombi owners. My first car was an Alfasud, so I kind of like horizontally opposed flat 4 engines.

    Thanks also for the info on EFI and VW engines. I've done a couple of Google search, but nothing really jumps out in terms of a complete, ready-to-go EFI kit for VW aircooled engines, which made me think perhaps its not a popular conversion. It probably also says that there's no such thing as a bolt on EFI kit :)

    As for engine swaps, I dropped a 2lt Twin Spark engine from a 1989 Alfa 75 into my 1968 Alfa Romeo GT1300 Junior. It works just fine... but never again am I going to fiddle with an engine swap. You change one thing and end up having modify half a dozen other things to acommodate the first change... and on it goes.

    Regards,


    Nick

    Ah, let me count the ways... and the angle grinder cutoff wheels, and the rolls of MIG wire, and the litres of POR15.

    Thanks, I'd forgotten about those guys. I looked at their gear when I was thinking about an EFI kit for the Alfa. I was hoping to find a VW specific kit or specialist.

    Nick ..Rob here, good luck with your search for a bay and your wish for a FI 2litre. I have such an engine possibly for sale as i am considering putting a 2.5 subaru in..keep in touch if you wish

    Kits mooted for some time but not a common or sorted product to my limited knowledge.
    seems Mike at CBB is ahead of the game on making something work.
    He is well regarded as no BS and well skilled which is relstively rare in vw circles.

    Subygears conversion for box also a sorted option.

    I like the injected idea but would drive to sydney to have Mike fit and fully tune the system.

    You won't find better than Mike at CBB VW in Penrith NSW. Mike has worked very closely with Haltech in developing their systems . (They even credit him in their documents)
    He's a VW specialist that installs EFI to VW s....both air and watercooled. In-house dyno's every build for optimum performance.....:cool:
    Lots of folks here go to him, myself included.....can't recommend him highly enough.
    Cheers,
    Mark

    Welcome to the Kombi Club Nick. :)

    Love your work on the Alfa, and a Kombi will be no harder to achieve a similar result. ;)

    A comment I heard about an Alfa recently, was: "On a quiet day, you can actually hear it rust." :eek:

    Kombi's are slightly thicker metal, so possibly rust silently....... but only when neglected.


    Enjoy the ride..............:cool:

    In the case of Alfa Romeos, its not actually rust. It's a built in self-lightening feature. The older they get, then lighter they get :)

    If only we could believe those Italian designers cleverly integrated simple performance improvement as they age, by reducing weight after they passed manufacturing scrutiny.......:rolleyes:

    I ain't getting any heavier, but still don't think the performance is getting better with age! :eek:

    Well, actually, that one's true. I'd like to think I'm a little smarter these days, but the memory isn't what it used to be :)
