Are there any available? Does anyone have one?

I don't know, but try Augment Automotive, they have worked on a few race/ track 951s.

I think Dbilas make one also, I have had a few BMW throtlle body kits off them very nice stuff.

Lindsay racing in the states do them.

Is it necessary in a turbo? there are a million tuning options I'd look at first

thats already all under control, new turbo, exhaust, engine management, AFM delete

There are many options available but the difficulty is matching one to your particular setup otherwise it may do more harm than good. If you are sticking with the factory intake manifold and a bolt on turbo there may be limited benefit changing from the factory cam unless you have a specific requirement.

Agreed.

You could try another intercooler first as well for more flow.

Turbo camshafts are also a little different to NA items ; they need almost no overlap unless the car is a full on race car, so choose carefully, especially given that your choices are only from the 'states (they tend to make something either road friendly (as in cruiser) or beyond racing only (read undriveable even for a racer).

I'd be tempted to give Newman Cams a call TBH. How much power are you making now? Is yours the Turbo running Emerald management?

Theyr Lotus profiles from Piper. Anyone can have them ground, but profiles for turbocharged applications are more troublesome than they are for normally aspirated engines (lift, duration and revs etc).

Isn't the 9r thought to be a upgrade which is a n/a cam.

personally I wouldn't bother changing the cam, you certainly don't need it for the road and can achieve big power gains retaining the original. I'd only go this route if you are racing in a modified class and even then it's questionable if the gains are worth it. Having said that if you insist on a more aggressive cam talk to John at Vitesse Racing, he will create a camshaft best for your setup... http://www.vitesseracing.com/html/944_951_968.html

More suitable overlap, wasn't it?

As Pedro says, the cam doesn't need changing and I wouldn't bother when there is so much to be gained from 'larger' turbos with better fuel, ignition and boost control.
