This is from memory, but I think the list below is exhaustive.
Assuming you are talking standard 951 (non-S) brakes:
1 pair front 1986-1988 (non-S) 951 calipers and pads
1 pair 951 rear calipers and pads
1 pair front 1987 or 1988 951 (non-S) rotors
1 pair rear 1987 or 1988 951 rotors
4 factory washers and bolts for the rear calipers from any year 951 (necessary to space them to fit inline with the rotor)
4 factory bolts for the front calipers from any 86-88 951 that is non-S
1 pair (left and right)of front hubs and spindles from a 1987 or 1988 Non-S 951 (complete with bearings on each)
1 pair of 1986 or later 951 front struts (your struts from your 87 N/A should work though as long as they aren't dead).
1 pair of front brake hoses from any year 951 and the metal noodles that go with them.
Additional pieces that I think you should get but aren't "must-haves" for some:
Bias valve from any year 951, this bolts inline on the master cylinder
Stainless brake lines front and rear
New alignment eccentric bolts for the front strut/spindle interface. Sometimes they are re-usable, most of the time they are chewed up and dead.
You'll need an alignment afterwards.
Hope that helps.

Pads are much easier to change on the turbo brakes. Just thought I'd throw that in, since I had to change the pads on our Lemons car and it was such a PITA compared to my turbo.
The n/a brakes felt pretty good to me on the Lemons car, but that was with hawk blues, which wore down the rotors like mad after about 8 hours of track time.

Personally I would go with the Rennbay Wilwood kit. Much less unsprung weight so your car keeps the light feeling the N/A's have over the Turbo's.....that plus good fluid and pads will be all the brakes you'll ever need on an N/A.

Any hard info comparing the wilwoods to turbo brakes? There was some stuff on the 944 v8 conversion forum about lexus caliper upgrades but a lot of the info mysteriously disappeared...

Burning Brakes
What is the cars use?
I personally feel the NA brakes are more than satisfactory. Install the right pads, provide some cooling, and have good rubber. I can lock-up my wheels easily with new R-compound rubber and I never have fade problems. Bigger brakes would offer me little gain.

AND, you can't run those 16X7 Fuchs with those small 205 tires unless you buy 951 Fuchs. Fuchs with the 911 part#'s won't fit over the turbo calipers, hence the 951-styled Fuchs wheels that carry a premium on the used wheel market for both the 944 and 911 guys wanting bigger brakes but keeping the classic looks.

Yep, if you really want to.
I'm going to throw a yes vote out for the larger 951 brakes.
You will notice better braking, especially if you are going with larger tire widths and sticky tires. The 951 calipers are actually fairly light, I know the rotors weigh somewhat more but the delta in weight difference isn't as great as you may think. Plus the larger rotors and calipers do dissapate the heat faster thus helping to keep any brake fade at bay.
I agree on a street car some could consider them to be overkill, but I think they are a great upgrade and if you shop smart for used parts it truly is a nice upgrade.
Not throwing sand at anyone who likes their N/A or Willwood brakes. Just my opinion.
