That's my understanding of what you need to do; shorten the bell housing and the input shaft, IIRC. Think the latter requires machining and then re-hardening.

Is this better/easier than trying to move the engine mounts? The advantages seem to be that you could avoid cutting up the body, and you don't move the center of gravity any further back in the car.

Any comments?
Although moving the CoG backwards definately seems like the wrong thing to do, ask yourself how far it's going? It's about 1 inch, right? Really think you'll ever notice that?

However, when all the little things that don't make much difference on their own (intercooler, turbo/plumbing, tail, 930 box etc. etc.) get added up it cumulatively makes a difference. And it's all in the wrong place, too...

I'd argue that you're building a hot rod anyway, and building a 930 out of the 911 is the wrong way to go - starting with a 930 roller would be a cheaper/better way, if that's where you wanted to end up?

So, uprate the TBs and the brakes (3.2 brakes are cheap/light and work fine for the street), use a 915, keep it narrow-bodied and as light as possible, put SC flares on it and squeeze some bigger tires in, maybe some bolt-ons to reduce lag, breathe better & keep safer.

You end up with a car that looks like an SC but has about 6.5 # per HP, and the 5-speed gives eyebrow-raising acceleration all the way to redline in top.

Of course, it's your money...
'77 S with '78 930 power and a few other things.
