I think there are advantages to the VW/AUDI/Boxster box hence to thought of using one on the engine.
It would be best to actually get a cheap one off e-b-a-y and get down to the oily bits...
I want to keep the light flywheel and clutch on the 911, but it is unusually small in diameter compared to modern parts, ie the clutch to suit these boxes.

Graham what about an LS3 V8 500bhp & 500ft/lb with just a cam you can fit a 911 996 gearbox with just an alloy adapter.
Not an expensive combination either.

Hard to beat an LS...if you have room for it.

There are people who make adaptors for Renault, Audi/Porsche and Subaru gearboxes for them, and no doubt most any other combo you could think of.

Another that came up recently that are cheap in the US...although not sure how much a working combo would be with a transaxle...is the V6 Ecoboost.

But trying to stay within Europe, a combo of VW/Audi parts would make the most sense as you could hopefully make most stuff work without lot of custom parts or adapters.

With a slight weight penalty...the VR6 engines are pretty cool...or a little less common but slightly more compact the VR5 that appeared for a while. VR6 would be well supported for aftermarket parts though, as would any of the 1.8 4cyl stuff..or indeed any other engines they use.

Richard, I'm not as young as you are or as brave!
The root reason for this thought is to improve the lethargic change of the Porsche 915 box.
If you rush it the thing will stall in neutral and take ages to untangle itself, I've all of 1 second, but as we all know that is hero to zero stuff.
I can't stand the thought of a total engine and box change prob because I've been a Porsche nut since 1988, or before most on here were born...

The Boxster engines are the easiest route and only need rads for waterquite cheap (relative term) and the big ones have 340 bhp and a ver high rev red line.

In the end, I think it will come to this.
The current engine and box are worth a lot in Porsche circles and would easily cover the Boxster drive train swop.
A lot of work to do it, and I would loose possibly a season doing it.

Run the current setup this season, buy parts, design, etc etc through the year ready for dismantling at the end of the year and swap over the winter.

Sticking with one brand, whether Porsche or other would be the most sensible option though.

I think you are right!
I feel better with Porsche All the Way.
At the Porsche Club HQ there is a cut away Boxster so easy to have a good measure.
Wife won't be pleased, so I'll blame you.

But Graeme, the car will be awefully poorly balanced with only half an engine and gearbox. And pretty sure you'll get chucked out of the club for pinching their display piece:-)

Ha! It's been there for ever, but is a weedy 2.5 so just over 200 bhp.
The much later cars are 300+ and 7600 red line.
Bomb proof too!
I'm selling it to myself....

I'm sure I've said this before...

Bite the Bullet, buy a secondhand FGC, adapt to the existing engine.

Sell Porsche box to help fund the conversion if required.

Job done, you'll never look back.

Happy New Year BTW!

Kind wishes, Graham.

I think you have Graham!
The change of the current box is slow and easy to 'miss' if I get excited or (more likely) clumsy.

If the engine did 7500 instead of 6300 red line all would be well as I could then reach (say) Triangle from Fletchers Dellow in 2nd, come out in 2nd, reach keepers in the same gear but faster, 3rd and use the torque to start up Cedar Straight.
Any change involving 2nd is an issue and the box is full of new parts put together by the best in the UK.

I also have some very stiff competition arriving this year which will prob inspire me to move on!
