Longnose crank swap/miata pistons

Looking for a complete Longnose swap (crank, pump, pulley, boss, etc) and a set of miata pistons to rebuild my GTX motor with.

Ah screw it. I have enough spares piling up.

I can pull apart the shortblock I have for pistons/rods and I got a longnose crank + bolt/pulley and I think all the little bits needed to use it from Gospeed (if I remeber right).

Willing to sell, just have to find a nice box like it came in.

Are you really looking for a "long nose" or "big nose"? big nose from a 1991+ will require swapping the oil pump as well.

Just FYI putting a Miata crank pulley on a GTX you should also change the water pump and alternator pulley out with 1.6l miata stuff. The V-belt on the miata is slightly wider than the GTX and things don't line up quite right if you mix and match pulleys.

I think I got 1.6l miata alternator and water pump pulleys lying around you can have.
