kombi EFI system

hey
can someone tell me if the kombi EFI system use an in-tank EFI pump or an external inline EFI pump?

according to both the bentley and gregory's workshop manuals the electric fuel pump is external. It is mounted to the left hand body side member.😎

Definately an external EFI pump. Interestingly the fuel tank has an internal like swirl pot mounted within it. Looks like a cats milk saucer welding in the bottom of the tank. Both the intake and return come & go from the middle of this saucer. Works great, I've injected a Kombi with no need for an external swirl pot for this reason.

Stock works better or best in some applications!

hey
thats good ill be using this for my V6 conversion!!

OK, stupid uninformed question here 🙂

will the kombi EFI manifolding bolt up to a motor in a beetle, with twin port heads, or suitable heads etc?

as in will it fit under the standard bodywork in the standard engine bay 🙂

and standard EFI Kombi is the 1971cc motor? whats the chances of picking up full loom, computer,. manifolds from a kombi and bolting them up to our beetle, which is already running (I think) a 1971cc motor?

The beetle motor is a Type 1

The kombi post 1974 is a Type 4 motor.
Although similar looking they are different. Head port angles are all different. In other words it wont fit.

Later beetles came with fuel injection on a Type 1 motor.

There are fuel injection kits available. But read $$$$

No. Kombi FI is to suit the type 4 motor, not the type 1.
The system will need to be modified to fit a type one motor.
FI wasn't all that uncommon in Kombi's so the do pop up at the wreckers from time to time.

thanks guys, from what I can find out about this car it may even have a type 4 motor in it.

anyway, can it be done, even if it means using a type 4 motor, as in is there enough clearance around the engine to run the FI manifolding?

I'm not concerned about head angles etc. as I can work around that, I'm not scared opf getting my hands dirty, and I am aware kombi EFI isnt THAT uncommon

Hi guys,

This is a link to our club site with pictures of what I did to my beetle using Kombi bits and a welder. Didn't like twin throttle bodies so this was my answer. Works fantastic.

Kombi plenum chamber grafted onto a type 1. Been on the car for 7 years now and fits in with the decklid fully closed!

Cheers Leigh

Rota, from the picture of your engine you have posted before it is 100% certain not type 4. Im also near 100% certain that it is not near 2 litres in capacity cos you wouldnt do that with single port heads.

You cant use the kombi injection. If you were to fit a type 4 engine into a beetle you would have to convert the cooling system to upright and then the manifolds wont go on. Theoretically you could use everything else if you made your own manifolds. However its a single throttle body system and to make manifolds that go over the altered cooling would mean they are extremely long and would look messy.

thanks amazer, but I have been told by the previous owner it was around 1900-2000 cpacity motor, and it was from his old baja, also on this forum, people have said old buggy boys used the big capacity motors, with single port heads and single carb, as it kept air velocity up and gave extremely high lowdown torque, but bugger all topend, which is apparently good for a buggy, and is exaclty how this beetle drives.

but thanks for that, I have NFI what the difference is between type 1 and type 4 motors, and really it doesnt worry me, its my girlfriends car, and we want to make it go faster, so far next mods are twin port heads when we can afford it, and I am thinking if there is a readily available bolt on EFI manifold, its not hard or expensive to source an aftermarket fuel only ECU, get a surge tank made up, and get it all running 🙂

especially when I am a mechanic, my brother is an auto elec, I have a friend that does s/steel fab for a living, and I know some of the guys from local workshops pretty well.

ah well, tein port manifolds with welded on injector bosses and custom centre section looks like the easiest way to go.

I don't know much about them, but perhaps you could use some of the parts from a factory fuel-injected type 3?

You can use the factory type 3 injection manifold, but it needs to be modified to fit around the Type 1 upright fan housing.

Works very well with a turbo blowing through it too.

ahh thanks, so its type 3 injection stuff that I'd be after really, anyone got any pics of type 3 EFI engine bays?

really just looking into options ATM.
