These sound like good transmissions that can be had for a decent price. Is anyone using a Suby motor with an aircooled VW or Porsche motor?
If you are can comment on shifting, costs, instal, chassis mods, etc....?
Thanks in advance.
Oh, one more thing - is it heresy to use one with a VW or Porsche engine?
You'd most likely be looking at an hydraulic clutch and a cable shifter, right? So add that to the cost of the half shaft adaptation, and take a couple grand off the price of the Boxster trans...
Heresy? Please....
Make sure that you wash that open wound on your back with 91% alcohol after flogging yourself with that sharp "Cat of 9 Tails"...
I have thoughts on a cable shifter. Just need the right project to come along to finish up the R&D.
Talk to the guys at http://www.subarugears.com/. They do other conversion things not mentioned on the website and it's pretty closely related to what they specialize in so they should know. I think Jake is or was the exclusive importer of some part of their line, so they may just refer you to him. I'd recommend checking directly with them first in any case, because I think their experience in this area is probably broader than Jake's and they may have the answers you need for your evaluation.
Keep in mind the ratio of the top gear will be a problem. Aircooled engines need to be spun quite a lot faster at cruising speeds to keep them cool, while Subaru ratios will be for lower, more normal RPM's.
^^ Actually it says on the main page adapters coming soon.
And here I thought keeping my 901 behind my Subaru motor was nuts... It would be spendy I imagine... And after you get to the point of stacking up a motor to it with the added thickness of an adapter the trans would stick out quite a bit. From what I've seen most Subaru motor/ trans conversions are long in length and encroach on the space the stock exhaust would sit. Also the diff itself sits low in these trannies, so u may loose some ground clearance albeit in line with the wheels. My 2 cents... If it matters. Don't let my ramblings discourage you.
Todd at Subarugears is finishing up the aircooled adaptors now.. I will be placing another big order with him in July if you want one :-)
Purely research at this point.
From what I've read elsewhere, might have been shoptalk forums, it sounds like the engine will have to sit higher in the chassis. The number that pops into my head is 55mm.
The height is an issue for me, too. Mine will mated to a 2.5 -6.
If I do it!
Hey guys, Todd from www.subarugears.com here.
Our products are available in North America from Jake Raby.
I also sell direct through my website but for many customers they like to deal with someone on the ground in the USA, since I am located in Sydney, Australia.
Jake has a great history in VW's and Porsche's and can give you all the support you need.
I have indeed developed a billet aluminium adaptor for VW/Porsche engines to bolt to the Subaru 5 speed transmission. This is supplied with a billet steel flywheel which is basically a lightened sports Subaru flywheel with the appropriate integral VW/Porsche center and correct spacing for this combo. I have the large single bolt centers for T1 style engines and the multibolt centers for T4 etc engines. They have the appropriate grooves for the different o-ring seals and crank seals. All flywheels are billet machined with an integral ring gear cut into them rather than pressed on.
This way you use standard Subaru clutches, release bearings, forks and starter motors. Nobody wants to have a clutch plate wear out and then have to get some custom riveted/welded center in a clutch. The range of Subaru aftermarket clutches is extensive and very competitively priced due to the huge aftermarket Subaru scene.
With regards to clutch cylinders, my preference is to fit a Subaru master and slave clutch cylinder, but this is not necessary. You can also use a clutch cable on these if you like. I drove a turbo beetle just last week with it's standard cable still in place and the action was smooth and light.
I haven't yet made the adaptor plates available as they have not yet been tested in a car. I will not sell them until it has done some time in an actual car and we can make sure it's perfect. I am currently building a 5 speed trans and adaptor plate combo to mate to a 1600 ACVW in a Kombi. This will enable us to prove the product and then release it for sale. Don't worry, you will know about it. Target price is $999 shipped to your door worldwide.
Don't forget we do Subaru 5 speed front drive conversion kits with the Subaspool 2WD locking spool, Subaflanges to suit 100mm or 108mm cv joints and the Subaplate to block off the back of your trans.
Input shaft to output shaft is 55mm or 2 inches greater than a VW/Porche setup - does that mean anything in reality when installed? I doubt it - but the proof is in the pudding. It needs to be built to be proven. Transmission length is the same as an 091 Kombi so is no issue to fit into a teener.
Keep at it and good luck with your conversions.
Thanks for the post, Todd!
Please post here again when you've got that Kombi working!
