Are you consistently overheating the brakes now? A v8 swap doesn't mean you need bigger brakes unless you're driving at high speed all of the time.

The stock brakes are more than capable of stopping the tires quickly, even with the extra weight and potential speed of a V8 powered 944. Stopped tires = locked up and bigger brakes won't help at all.

Now, how much tire do you have on the road, how sticky are they and are you running into tire lock up or brake overheating issues?

Or are you just after the look of the big reds with the Porsche cast into the side of them?

Options are:

Stock brakes with titanium brake pad backing plates, brake cooling ducts, more aggressive dual-purpose brake pads with braided stainless steel brake lines. All bolts up just like stock, parts are relatively easy to find at a parts store, etc.

Volvo 2-piston front calipers from a 242, etc. w/vented brakes and stock 944 rotors and uprights. Similar as above since Volvo's are so easy to find and it is only a change to the calipers and drilling the caliper to accommodate a single brake line. Cooling ducts, braided lines and master cylinder can stay the same.

Rennbay big brake upgrade kit (uses Wilwood calipers) and stock uprights. Good solution, Wilwood parts are pretty common in the performance world, doesn't change the geometry of your front suspension.

944 Turbo brakes (Black Brembos), requires different front uprights (you could lose the stock speedometer drive) rotors, front struts, master cylinder and rear calipers. Depending on the year you choose to source your parts from, could also change the offset of your front hubs and require a wheel change to compensate and clear the larger rotors and calipers.

911 Turbo caliper upgrade (Big Reds), same as above, plus you need the appropriate 911 calipers.

Personally, unless I'm looking for the "look" with the Porsche cast calipers or I'm consistently overheating the brake fluid/pads I wouldn't bother with the turbo brakes unless you luck into a donor.

Good luck with it. Would love to see some pics of your car, if you have them.
