[Bob's944]

I checked out the JM Engines site, nice looking setup, but look at the cost for what you get. They quote a 30 HP improvement on a 400 HP 944 turbo (wow someone is alreading spending ALOT of cash), that's 7.5%. They don't quote a price for the turbo set-up, I'm sure it's higher than the $4600 they do quote for that sweet looking NA set-up, which they don't quote any HP increase numbers.... strange, makes me believe the NA set-up has less increase percentagewise than the numbers they quote for the turbo. If your getting around 200 HP out of your 944S, and IF it produces the same 7.5% increase of power, you might end up at 215 HP for about $5000 if you do the labor yourself, I'm assuming a porting job is going to be needed also to make the change effective. My guess is that you will find alternatives ways to achieve a similar increase by utilizing the existing intake manifold, doing a port job, adding or changing injectors, and maybe some of computer remapping which would cost far less. A 400 HP turbo engine has already had all that kinda stuff done, so this really is for people that are truly maxing it out.
