AE and Borgo are the same. If you have standard compression pistons in the
engine, and the replacement is also standard, then just go ahead and fit it.
This type of repair is done quite often and there shouldn't be any problems. I
presume that the engine is out in which case you can easily remove one of the
fitted pistons and check against the new one. Weigh them as well if you like:
good kitchen scales work fairly well for an approximation if you don't have
access to a proper balance. Allow for the carbon etc on the old piston.

Subject: [alfa] mixing piston types

	My GTV needs to have one piston/liner pair replaced after the oil ring
fell apart and ruined both the liner (great big gouges) and the piston
(part of the piston between the wrist pin hole and the oil ring land
disappeared).  I had rebuilt the engine 2 years ago and replaced all the
pistons and liners.  After calling around to various Alfa suppliers who
only sold the piston/liners in sets of 4, I found IAP would sell a
single set ($99).  It arrived yesterday where I discovered that the
piston/liner was made by AE whereas my other 4 pistons were made by Borgo.

	Can I just go ahead and replace the Borgo with the AE piston or should
I make sure that I have a Borgo replacement piston?
