All s14's have t28 standard... only s15's came standard with the t28r(roller bearing)

The t28 has 4 bolts on the compressor housing where as the t28r has 6.
Also when you turn off the engine with a t28r fitted you should hear the turbo spooling down for about ten seconds after the engine switchs off

apparently the late late japanese s14a silvias came with the ball bearing t28. also the later s15 turbos were ceramic.

but afaik all uk s14 and s14a turbos are the same!
