Does anyone have any numbers on what the Subaru boxes are rated for in Torque (ft-lbs)? Having a six speed is nice if you have a peaky high reving engine where it's tough to stay in the torque band.

Up until the recent drops in HP and tq on those cars, they used to be delivered with 280/280 from the factory for the late '90's and into MY00. People consistently put upwards of 350 through them. And there are significantly stronger gearsets available if you are going for broke. I have Albins gearsets for them, and PPG, also in Australia makes gears. But they are not cheap. Like $2500 or more a set. Stay away from the modern STi-RA replacments you can find for $1500 or so. They are no longer made by Albins and people are seeing failures right and left...

These parts are only for the 5-speed trans.

The only thing that would see more stress in the AWD to 2 wheel drive is all of the power will be going thru the ring and pinion intsead of some to the rear and some to the front. The actuall transmission portion doesn't know how many diffs it is driving.

The Audi transmissions have the starter in the wrong place and facing the wrong way for a Suby or VW engine.

I'm going to order one set of parts within 24 hours - anybody want to add to the order?

i am also talking to them as to whether or not this will fit the auto box just incase anyone is interested , i am currently running the auto with my ej20t

hey what about the speedo anyone? anyone?
darned if i know ,any ideas anyone?

[Porcharu]

The FWD automatics should be easy to find, no need to convert an AWD unit.

[banksyinoz]

cant say ive ever even seen one here and mine is a 94 box but i will investigate (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

Just spoke with a suby owner buddy of mine and he is saying that the 5-speed of choice for the high power WRX guys is the STI RA from the Version5 STI. Very strong tranny with 5 gears instead of 6 that are right on top of each other.

This is some good info but just to clarify for myself, you are all talking about which Suby trans to use behind a Suby engine, correct? Has anyone mated a Suby trans to a Porsche -6?

[Porcharu]

I just found out that a bank wire transfer costs $50. Does anyone else want to split the wire transfer costs? I am ready to order the parts and have 2 other people that want 3 kits. $190 per kit plus a portion of the wire transfer and shiping to your place.
I am placing the order on Monday.

BTW - Sager is changing from the cast aluminum plate to a CNC'd billet aluminum plate. They even offered to put the club logo on the part if we have a group buy.

[Porcharu]

I forgot to add that this kit is only for the 5 speed - NOT the 6 speed.

If you're dealing with a reputable vendor, simply use a credit card to avoid wire transfer fees. You'll also nail down the exchange rate, otherwise it may change during the transfer process.

You could also just mail him a check. The banks will take some fees and it's exposed to currency fluctuation, but it doesn't cost $50.

spoke to a guy who is mad on early kombies ex porsche mechanic over here he put me on the right track with the 2wd auto so i might just have to see how much they can hold for $450 a pop, he also told me that they look just like a normal box with out the rear drive and that the rear cover has a mount cast into it it may be useful information (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Hi guys,

I'm contemplating a suby conversion "one day", and the thought of have a 914 with crisp modern shifting is really enticing. I'm a little ignorant on mechanical things outside of the 914 though...

1. Am I reading correctly that the Subaru transmission uses cables, rather than a shift bar?

2. How would you mate up the rear transmission case to the 914? Fabricate custom mounts for the 914 body mount areas?

3. This plan works with the Subaru automatic as well as the manual?

Thanks - Again, pardon my ignorance...

1. not 100% but shaft i think but u would probably use cables

2.you can use the original mounting points of the 914
the five & six speeds have a mount under the box straight below the 914 ones, auto awd need to have a mount built to support as its nearer to the rear of the box as well as the 2wd auto as i have been let to believe,
so to say they have to be fabricated although not very technical
good luck (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

[Porcharu]

I am planning on using the original (914) shifter and as much of the linkage as possible.

Yes custom mounts need to be made up.

The auto trans should be easier to swap in, no clutch linkage and a very simple "shifter"

[nsyr]

what about cv hookup?

[MrKona]

So let me make sure I've got this right... If you use an automatic transmission, you are (theoretically) using the stock shift linkage (and some cable possibly) to shift from "1" to "2" to "P" and "R", as if you could with a standard automatic transmission? (Minus a torque converter)

You'd lose the need (and the ability) to drive with a clutch?

Also, regarding NSYR's question, have you give thought to the CVs?

Thanks - this topic is pretty interesting... (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

[MrKona]

On second thought, I guess the torque converter is part of the automatic transmission... very confusing, must go to bed. (IMG:http://www.914world.com/bbs2/html/emoticons/yellowsleep[1].gif)

[banksyinoz]

found some 2wd trannies over here $1100aud what a joke i can buy an awd wrx with auto front cut for 2000.

914 cvs with suby outputs mated to them it looks factory

suby shifter, looked at longer cable ,up under dash down side of car into boot down through floor to auto, this then is the same as the suby, b&m make longer cables that would be very simmilar

autos have 4.1-1 final drive
manuals have 2 . 3.7-1 , 3.9-1 (as i have been told)

took some pics with the slr this morning will have them developed and post tonight ej20 auto in the car with the extension housing removed including cvs (IMG:http://www.914world.com/bbs2/html/emoticons/aktion035.gif)
