purchased S13 calipers (non turbo) not sure if there is a differences between standard and turbo....anyways are the rotors 250mm or 280mm I need for the job!

Either size can be fitted to the 1200. See S13 Brakes.

ok thanks, on calliper said: 29W, B43, H3 not sure if means anything...and on old pads BM1462

BM1462 appears to be the pad formula, doesn't tell us what caliper it is. Got a pic?

Best to get the calipers matching the rotors:
280mm rotor + 280 sumitomo caliper
250mm rotor + 250 caliper

Do you want to go to 15" wheels? If not choose the 250 mm rotors.

not having much lucky up loading pics, the only site I have trouble with frustrating

Then upload to another site, and link to the photo here.

The main problem is the size of the photo. We can upload a 1.3 megapixel photo, but the site won't auto-resize larger photos. It briefly shows a message stating what the problem is, but if you aren't watching you probably missed it.

Good pic. I'd guess that is the 250 mm caliper.

The two calipers look very similar. It's the factory bracket that differs the most. You'll need it for the conversion, in addition to the custom adapter.
