Porsche Tranny use in Vanagons

开云体育

Hi Everyone,
?
Been following all the email and dreaming on my rebuild.? I really would like to mate a six cylinder Subaru to a Porsche tranny when the time comes.? The tranny could easily handle the power and having the ratio choices and a limited slip would make for a great way to get the power to the road.
.
??? Does anyone know the contact info for a shop that does the Porsche tranny conversions?? And has the mounts, clutch and linkage properly figured out?
?

Try Marty Schneider of MSDS
<MDM810@...> or

www.msdsinc.com

He makes a complete "Range Panzer" kit to convert a T25 Syncro to 911
engine & G50 trans; will fit nonSyncro. He doesn't like selling a trans kit
separately, just a full engine/trans kit, but did say he'd sell me a
trans-only setup.

If enoughSubaruvanagoneers bothered him he might begin to sell "half" kits
willingly (the Half Marty?).

KEP makes adaptor kits for Subaru to 915 and G50 (flywheel, adaptor plate).
You need to provide the clutch, starter etc.

As far as fitting trans to van, npbody makes a kit for a 915 trans, which
is far weaker than the Getrag G50 anyway, and a little prone to syncro and
bearing wear; its clutch mechanism needs adapting to hydraulic. The G50
also has a normal 5-speed gate and good shift-action, unlike the
Vanagon-style gate & action of the 915. The old 901 trans is far too weak
to consider.

To fit a Porsche trans you will need the complete gearshift mechanism from
the car the trans came from (or an identical car). The VW shifter won't
work.

The 915 trans will fit your 100mm VW CVs, and stock T25 axle length may be
correct. The G50 takes 108mm CVs; normally Porsche 930 CVs are used, but
are extremaly expensive new or used (PartsHeaven in San Francisco says
$124US new complete, $175 per pair on axle used). Beware, the US places do
not offer a complete CV at the advertised prices; $50-odd covers only the
inner parts ie balls and cage, NOT the boot or base/flange.

I am trying to find out whether the Type 44 Audi 100 (=5000 in USA) 108mm
CVs will fit the 930 axles ie is the spline the same, length ditto. I'm
waiting for a fax from a wrecker who was going to measure up a T44 CV for
me.

Sway-a-Way adaptor axles are needed, also Weddle 108mm stubaxles (outer
flanges) .

In USA a good used G50 generally costs $1800. In Germany I am buying one
for DM2700 (about $1291US) including release mechanism and slave cylinder.
Starter DM280, complete used clutch & ringgear DM1100, shifter complete
from shifter knob to trans DM450, FAR cheaper than US prices. No 930 CVs
available. Even with shipping the total cost saving over USA is big enough.
The difference is over $2000NZ (@$0.42US); shipping about the same either
way.

Compare to US prices:
trans 1800
clutch new 695
ringgear 60
release mechanism 150
slave cylinder new 57
starter 125
shift lever, coupler, linkage 550

Warren Chapman, vanagon.com member, has an Audi V6/G50 in his; Jurgen
Gembler (runs www.bulli-forum, Germany) has a VR6/G50.

Hope this helps.

Maybe my SVX/G50 T25 will be on the road this half of the century...
