Correction. the XR2 was a later model car 1991-1994 it probably came with a big nose crank and miata rods. The big rods stopped being produced in 1990 I bet.

I have seen several Capri turbo motors apart and there was no diferance from a B6T GTX. I suspect whoever you got them from swapped them out. The Capri did have slightly different engine management I think however. And when Mazda Built the 1.8L BPT it used miata rods in everything but the GTR version which used better forged rods.

Post 4 holds to what I'm claiming.
From everything I've read, anything PRE '89 got the beefier b6t rods. Anything POST 89 (Ford/Mercury especially) got the standard miata rods.
Of course, this is all internet speak. I've never owned an XR2 or a GTX, so I have no personal frame of reference.

There appear to be some discrepancies here.

They had “Big nose” after the changeover date in 91 would be my guess. Long nose was a replacement only on 1.6's and standard on 1.8l's pre changeover date in 91 only. I did have a long nose 1.8l escort motor and I have seen a long nose BPT that wasn’t a big nose.
