There is a Australian kit that converts them from 4 wheel to 2 wheel drive. I understand the shifting is super solid and fast, but would like to hear from anyone that has done one in a 914.

Yes, my car (and several others here), and all true.

So you can adapt an impreza transmission to a type iv?

No need to change trannies to get what you want. Just get a good 901 or have the Doc rebuild one for you then convert to cable shift. TAYQ, Renegade may start making the adp's if enough interest but I don't know why anyone would. The 901 will handle 99% of the type 4's.

No, mine's behind a Subaru engine. I had a 901 box there before, so a good A-B comparison, and the upgrade to the Subaru was three times better than night and day. But no, not behind a T4.

I would agree. I absolutely love my suby conversion with the suby trans. Shifts so smooth & easy. The cable shift setup so nice. I wouldn't go through the trouble of adapting one to a type 4 though .

you can also get the awd to 2wd stuff from ian, cheaper.

be sure to consider all that might be involved.
I assume you are not running heat?
running headers?

Great information. Thanks Jim.

Headers, yes

If I build a turbo 4 I'm going to need another transmission. A well build 901 is good up to 250HP, but beyond that they are going to break. I'm looking for 300HP to the rear wheels, so will need a transmission. It's the same story with a turbo 6.

Of course the other issue is the LSD, or in my case a torque bias differential, which for my racing venues is a must.

As long as I have to do the transmission I'd sure like to find something that shifts faster and better. You can laugh, but the first to second shift and the third to fourth shifts are slow. Doesn't seem like such a big deal, but make four/five shifts on a 50 second course and it costs you time.

Looked at the sequential boxes, but they are big time expensive. Nice way to go however.

How about one behind a 3.2-6 ? I'm getting close on my engine rebuild and I'm thinking 901 with limited slip? 915? Are the Subaru transmissions limited slip?

I have an OBX torque-biasing LSD in my Suby trans. I have only driven my turbo Suby-engined 914 in my cul-de-sac a few times, so I cannot give firsthand experience with its long-term pluses/minuses... but the OBX unit gets good reviews on NASIOC. They're available on eBay for ~$450 shipped.

The same adapter plate that will allow a Subaru motor to mount to a 901 will work 'backwards' to allow a Subaru trans to mate to a T4. The troublesome bit will be the clutch/flywheel. Normally you buy a special flywheel with an extended mounting flange to account for the thickness of the adapter plate. You would need a Subaru flywheel with a T4 mounting flange. I doubt this piece exists. One possibility to pursue would be an adapter 'puck' that would mount to the T4 crank and have holes for the Subaru flywheel pattern. Of course that's one more piece to break.

In short:
Mounting - Easy
Axles - Easy
Flywheel - Hard
Shifting - Not Easy
Clutch - Not Too Hard

That's pretty-much the perfect synopsis.

So a flywheel would have to be machined?

When you say shifting would be difficult, do you mean it'd just take a bunch of time to sort out a cable shifter, correct?
