Kombi with EZ30 and Subie 5 speed transmission
ttriebler - December 23rd, 2011 at 04:00 PM

How about this for a great conversion. Danny in Christchurch put this EZ30 3.0 litre 6 cylinder motor and matching Subaru 5 speed into his 76 Bay Kombi.

Two Honda Civic radiators in the back with Subaru fans controlled by the factory ECU - and no cooling problems.

Maybe some low profile exhaust manifolds in the future and it's sweet!

Hi

That looks like it would be fun.

Ben386 - December 24th, 2011 at 04:29 PM

Well done,nice work.


kaiisons - December 25th, 2011 at 09:28 AM

does he have a build thread?


ttriebler - December 25th, 2011 at 05:04 PM

Nope...wish he did. He is going to do a drive video for us though - should be sweet.


Subarugears - December 25th, 2011 at 06:44 PM

test new username


lou0060 - December 29th, 2011 at 08:48 PM

this will fly....

wonder if that combination would fit in a type 3 wagon???


Subarugears - December 30th, 2011 at 02:17 AM

Yep I reckon it would easily fit. Here's an EJ22 in a type 3 notch with Subie 5 speed.
The EZ30 is a poofteenth longer and check out how much space is still left :

Todd, are you looking to do the 6 speed mid mount kits soon ?

http://www.sakercars.com.au/aus_gallery.htm 


Subarugears - May 6th, 2012 at 06:42 PM

Seagull 6 speed splitcase or 6 speed STi truck gearbox?

I am making my first locking spools for the splitcase 6 speed and have already done the subaplate (with special cover for the shift rod) for it.
The Subaflanges already fit the 6 speed split case.

I am not touching the 6 speed STi - there is no need, it is too big and heavy, can't be shortened enough and is expensive.
There's plenty enough strength in the splitcase 5 speed and 6 speed boxes, even more so in a 2WD setup.


seagull - May 6th, 2012 at 08:12 PM

so whats a 6 speed sti truck gear box ?

I am talking about the split case box


seagull - May 6th, 2012 at 08:26 PM

send me price Todd on the parts please


Subarugears - May 6th, 2012 at 10:03 PM

STi truck gearbox is the 6 speed you get it the STi's. Much larger than the boxes we know and love...and much heavier, hence I call them truck gearboxes.
Prices for everything are on the website http://www.subarugears.com  in the products section. 6 speed stuff is the same price as 5 speed stuff.


seagull - May 6th, 2012 at 10:51 PM

ok , now you have confused me

leave the truck gear box out of things you confuse me

so you will be making the 6 speed & the blanking plate soon ?

re split case 6 speed, are they all not split case ?


Subarugears - May 6th, 2012 at 11:05 PM

I already make the 6 speed locking spool, blanking plate and cv flange adaptors for the 6 speed.
I will be doing the 6 speed ring and pinions soon, have already tooled up, just waiting for market demand to be there before I do a production run.
They are the same as 5 speed, just a longer pinion to accomodate the extra gear.
I will probably have them available towards the end of the year.
By the way, I now have 3.9, 4.1, 4.4 and 4.86 ratios for a greater range (notice the VW Syncro ratio in there).

re split case 6 speed - there are two types of 6 speed. The split case 6 speed, which is the same as the split case 5 speed, just squeezed another gear into the same housing. Bigger first, constant mesh reverse, cable shift. As fitted to 2011 and newer petrol and diesel Subies. The second type of 6 speed is the STi 6 speed which has been on the STi's since around 2004 or whatever. It is not split case, it is a solid case and stacks together front to back. Totally different design gearbox.


seagull - May 19th, 2012 at 12:54 PM

The EZ30 sump is already short thats a win


do you have any photos of the 6 speed parts Todd ?

Here's the Subaspool, Subaflanges and ring and pinion for the 5 speed. 6 speed Subaspool is the same except has smaller splines for the gearbox driven shaft. Ring and pinion is the same but a touch longer to fit the 6th gear. Subaflanges are the same.

http://i1169.photobucket.com/albums/r520/subarugears/Components/Subarugearskitwhite.jpg

Here's the 5 speed Subaplate to close off the box when you remove the center diff and transfer gears from it :

http://i1169.photobucket.com/albums/r520/subarugears/Subaplate.jpg

Here's the 6 speed version which adds a cover over the shift shaft stub to keep all the oil in :

http://i1169.photobucket.com/albums/r520/subarugears/6speedplateandcover.png

Note the 6 speed uses cable shift. Also note the 6 speed is a touch longer than our shortened 5 speed as it still uses the full center diff housing. This is fine for Kombis and T3's. We are still working on adapting the shortened center diff housing and shift rod to get the 6 speed short enough to fit beetles without cutting through the torsion bar.


seagull - May 19th, 2012 at 11:14 PM

This may be of interest Todd as I am keen to remove the weight of the center diff, its a large mass to have to spin up for no reason.

you stated above the 6 speed uses a cable shift, what gear box are you talking about ? you have lost me there

Subarugears - May 20th, 2012 at 01:14 AM

Righto Seagull, if I have lost you, with all your Subaru knowledge, I will have certainly lost anyone else reading this thread so let me take it right back to basics.

This is the 5 speed splitcase gearbox we all know and love, that I currently reverse. It has the serial numbers TY752/TY754/TY755 :

http://i1169.photobucket.com/albums/r520/subarugears/6%20speed%20split%20case/5speedsplitcase.jpg

This is the 6 speed splitcase gearbox that has been produced since 2010 or so. It is an adaptation/revision of the 5 speed splitcase and has the serial number TY756. As you can see from the images, as a 4WD gearbox it is exactly the same from the outside as the 5 speed, except it now has a cable shift :

http://i1169.photobucket.com/albums/r520/subarugears/6%20speed%20split%20case/6speedsplitcase.jpg

http://i1169.photobucket.com/albums/r520/subarugears/6%20speed%20split%20case/6speedsplitcaserhs.jpg

Both the 5 speed and 6 speed splitcase gearboxes are called this because they can be split in half longitudinally to get to their gearsets. In the image below there is a splitcase 6 speed at the top and a splitcase 5 speed at the bottom :

http://i1169.photobucket.com/albums/r520/subarugears/6%20speed%20split%20case/6speedgears.png

Now there is also another type of 6 spped - the STi 6 speed (affectionately known as the truck gearbox because it is so big and heavy). This has the serial number TY85... and is NOT a splitcase box as it cannot be split longitudinally. The gears are all assembled on an intermediate plate and then lowered into the 1 piece housing. This gearbox is not cable shift. Below is a 6 speed STi gearbox :

http://i1169.photobucket.com/albums/r520/subarugears/6%20speed%20split%20case/6speedSTi.jpg

Now you posted a link to the Saker cars website and asked if I am doing the 6 speed mid mount kits soon. Here is a picture of the Saker cars and the splitcase 5 speed gearboxes they use :

http://i1169.photobucket.com/albums/r520/subarugears/6%20speed%20split%20case/5speedSaker.jpg

So naturally you mean are you doing the 6 speed SPLITCASE mid mount kits soon - which I have shown you I am already manufacturing.

Now in your latest post you refer to a photo from Possum Bourne motorsport of a 2WD locking kit for a 6 speed STi gearbox :

http://i1169.photobucket.com/albums/r520/subarugears/6%20speed%20split%20case/Center-Diff-locking-tube16speedSTi.jpg

I do not manufacture anything for the STi 6 speed gearbox. You will also find that Possum Bourne Motorsport does not manufacture anything for the 6 speed STi gearbox - that is why the price is listed as TBA and has been for years.

Most people have no interest in the 6 speed STi gearbox for 2WD applications because it is overkill and weighs twice as much as a splitcase box, thereby reducing performance.


seagull - May 20th, 2012 at 12:04 PM

In all my years of playing with subaru I have never seen the split case 6speed. Keen to find one to have a look

One issue with big HP with the split case as the 5 speed, is the bolts they strech. HT bolts over come this issue


Goes to show you you find some thing new every day !


Subarugears - May 20th, 2012 at 01:09 PM

The splitcase 6 speed is fairly new, being released in 2010 for the Boxer diesel. You can see how they revised the gear layout to give it a fat 1st and 2nd gear to cope with the low down torque of the diesel turbo. You'll also see reverse gear has been moved and is now constant mesh. The 5th and 6th gears are both overdrive gears for fuel economy. Note all the additional ribbing on the 6 speed casing to stiffen everything - no issues with the splitcase halves moving orbolts stretching.

I have one of these diesel 6 speeds in captivity, that's how I've been developing parts for them. They are now used with EJ25 petrol engines as well.

Am starting a new project here with a customer putting an EE20 boxer diesel turbo in a beetle. I am supplying him a 5 speed 'Hybrid turbo' fully built Subarugears transmission to mate up to it and prove how tough the 5 speeds are with the diesel torque. Will start a thread on it once the build commences. I think that will be an interesting read for dubbers the world over.


seagull - May 20th, 2012 at 08:43 PM

yep, currently I am stitting on a cosworth with 700hp at the wheels

happy to test one for you. I get on to Alibarba at track one down


seagull - May 20th, 2012 at 09:45 PM

what was the front diff ratio Todd ?


Subarugears - May 21st, 2012 at 12:05 AM

The diesel 6 speed had a final drive ratio of 3.9
Interesting gear ratios : 1st 3.45, 2nd 1.75, 3rd 1.062, 4th 0.78, 5th 0.63, 6th 0.56 - designed with economy in mind.


seagull - May 25th, 2012 at 08:36 PM

Ian droped off the kit tonight

do you know the drive flanges are cut off / ground down with an angle grinder ( gear box side )


seagull - May 25th, 2012 at 11:34 PM

When the transfer case ( gears & center diff are removed ) removed for the front wheel drive application. You have removed the way the gear box is oil feed to the main shaft. This will run dry and one will find blue hot spots on the bearing cages & shafts over time.

There will be some oil pick up from the main gears but nothing like subaru designed.


Subarugears - May 26th, 2012 at 09:08 AM

The transfer case is not removed for front wheel drive application.
The 4WD end plate that stops oil going out the back of the box is changed from one with an output yoke to one without an output yoke so oil doesn't spill out the back.


seagull - May 26th, 2012 at 01:12 PM

The trasfer gears & center diff are removed, in doing so you have removed the way oil is feed to the main shaft.

+ the drive flanges a frankly piss poor the way they have been hit by a grinder

Nope you're wrong. The oil level is high enough to cover the bearings. Below is how those hundreds of Japanese engineers designed this transmission as a FWD transmission originally. Then produced and sold a couple of million of them. There are no transfer gears and center diffs in these and they never had a problem:

http://i1169.photobucket.com/albums/r520/subarugears/FWD%205%20speed/SubaruFWD5speed.jpg

The Saker cars you refer to in your above posts haven't had any problem with just putting a block off plate on the back.

I have cars with my conversions with over 40,000 kms on the gearboxes and no problems - pretty sure that speaks for itself.

The last guy that got a FWD conversion kit from me for his 2.5 STi Porsche 914 hasn't had ny problems...


http://i1169.photobucket.com/albums/r520/subarugears/FWD%205%20speed/914STi2WD.jpg

Seems to be a pretty serious race car

http://i1169.photobucket.com/albums/r520/subarugears/FWD%205%20speed/914STiLagunaSeca.jpg

Seemed to have no trouble keeping up with all these other supercars at Laguna Seca Raceway...

http://i1169.photobucket.com/albums/r520/subarugears/FWD%205%20speed/914withothersLagunaSeca.jpg

His flanges have some grinder marks on the stub end as well. They are covered by the dust caps and slide up out if sight. I would have thought a non-issue but I will contact Ian (the customer) directly and offer him a refund or replacement. No dramas. :cool:
