i was thinking about doing this sort of thing for an off road buggy. if the gears are not meshing then couldn't i just put a spacer/shims behind the crown wheel? the other option was just to flip the box upside down but that brings other problems with seals and filling.

I was thinking about this and my thoughts turned to the Justy. Because if I understand it right, it's done from the factory with the rear engined stuff overseas.

 

Flip the Justy engine and trans 180* and install it in the back, the output shaft now points to the front...

 

Edit:The Sambar for one.

 

"1994 saw a full model change with a body similar to the Domingo, with the EF12

Subaru EF engine

 

The EF is an automotive engine made by Subaru, introduced in 1984 for the Subaru Justy.It is a water-cooled straight-3 engine with a belt-driven single overhead camshaft, and a chain driven balance shaft...

 

three cylinder engine's displacement increased to 1200cc and SOHC borrowed from the Subaru Justy

Subaru Justy

Since 1984, Subaru has marketed the Justy, a subcompact hatchback, either manufacturing the vehicle itself or marketing a rebadged version by others...

 

. A maximum seating capacity of seven was possible.

no it doesnt, you just flipped it left to right. it is a tranverse engine.

Make a 4WD Beetle/Buggy using Subaru driveline

 

 

wow

that would be something

 

This has been an idea of mine for a while, and even with the 1500 for the gear it would probably be cheaper than sourcing a Syncro drivetrain.

 

The wheels are turning, and that's bad, usually means I spend too much money.

 

Anyone have a beetle they don't want? :grin:

Hi Nipper,

 

? To get the output shaft to point to the front, you'd have to have a different trans case, with the shaft pointing the other way...

 

I'll think about it, but it's either one or the other. Flip it, or different trans. parts.

im looking at the FSM now, and have one in a driveway. If you are having a differnt tranny case, then why bother with the teansmission at all?

Hey,

 

Yea, it's not an EF-12, but EF engines were used in the same trucks. See how the spark plug wires are on the rear side? I would think the EF would be mounted the same. I'll see if I can find some more. And I'm talking about the 4WD models.

The Subaru Sumo, known as the Libero in European markets apart from the UK and Norway, also known as the Domingo in the Japanese market, was microvan produced from 1983 to 1998.

In Sweden, it was known as the Columbuss. It was also called the Subaru E10 and Subaru E12 respectively due to the size of the engine. The Sumo is the Sambar with extended front and rear bumpers and a larger engine borrowed from the Subaru Justy. Because of these modifications, it doesn't conform to kei car regulations, which stipulate the maximum dimensions of the vehicle and the maximum engine displacement requirements, which then determine the vehicle tax to be paid.

It was launched with the option of four-wheel drive and powered by 1.0- and 1.2-litre 3-cylinder EF engines based on those used in the Subaru Justy although in the van they were rear mounted. Somewhat unusual for a microvan, the 1200cc Sumo could be ordered with selectable 4WD, operated via a gear stick imbedded button. In normal driving conditions the rear wheels only were driven, there being no central differential to allow highway driving in 4WD mode. In 1994 , Subaru's Full Time 4WD was added to the options list with the ECVT transmission only and a viscous coupling. An oil cooler was installed on European versions to better facilitate light duty towing.

 

Hey Nipper,

 

The two axle stubs like your 2WD would drive the rear wheels either way it was mounted. The output shaft for 4WD of course points to the rear. In these trucks/vans the engine would be flipped or different case/shaft parts installed to point the shaft to the front for four wheel drive.

i have been thinking about buggy'ing a ea gearbox for some time well if it is possible to swap the diff from one side to the other and that looks possible and the gears should have the right mesh on them im guessing that its just a matter of shimming the crown wheel. well now im intrigued so i think ill pull a gearbox apart and see what will work

 

but as NoahDL88 said

the EF engines have some issues, so I wouldnt use one as an upgrade for anything. They have oil pumps that were poorly designed and eat through their housings. No oil pressure is very bad. This is partially because of the tiny oil pan and longh change interval (7500 miles on 3-4qts is way too much). If this is not reduced greatly, or oil capacity expanded it can be a huge issue. the replacement housing is far from cheap. Parts are still out there for the engine.

 

When doing a conversion, usually you go up in power, not down. a 3cyl will be going down.

 

And from that picture it is still a tranverse mounted transmission.

i have decided not to look into a gearbox until i have finished my non Subaru projects like the sr20 mini and the 50 foot ocean going house boat. otherwise i would be building a buggy as well and i don't have the time or money for that. if someone else can look into a gearbox and figure out what needs to be done and not get stuck building another project car then that would be good

They did.

 

It's in the link that started this thread.

 

Doesn't work unless you buy a reverse cut crown gear, THEN flip the diff in the case.

i was just thinking that the original gears could do the same job (and be a lot cheaper) they should mesh together the same because they are driving off the other side of the pinion and be running on the same face of the teeth that they where designed to run on. i was thinking that it would just be a matter of shimming the crown wheel from the diff or getting it machined down if it is to thick. maybe they looked into it and worked out that it just needed a thicker crown wheel and that's what they are making they would not tell anyone that because then they would not be making any money.

 

well that's my 2c

it works on the VW Bug transaxle cause its all centered on the subaru its not centered , its opposite what you need
