1991 Testarossa engine question

I'm looking at a 1991 Euro spec Testarossa from Switzerland....The Vin is correct for Switzerland but the engine number is F113AO40....from what I've read the Swiss car should be an F113AO46 or F113BO40 engine.........could this be a replacement engine or possibly changed when imported to meet US regulations for emissions. If a replacement engine how much less should i be paying and how much will this lower the value of the car if i try to sell it..........

Welcome to Ferrari Life. You need to take the VIN, or serial number if pre-VIN, to Ferrari and ask them what engine was originally fitted to her. Should give you all the info you need. I have a couple of Swiss TR owners manuals, but they do not have that level of detail.

Sounds like the A049 engine may just be an upgrade of the A046, but I am no TR engine expert.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
