There is no 'official' Bosch replacement for these injectors (Ferrari p/n 144256), they were discontinued last decade. Bosch p/n is 0 280 150 419. I'm sure you'll be able to get your hands on some NOS somewhere though (I think Eurospares had them listed as available). Good luck.
as ross write: bosch not making them anymore but here are some specifications, may be one can encrypt to other manufacturer? static flow at 3 bar, medium n-heptane: 155,2 gr/min resistance: 14,5 ohm volvo has the same injector, VOLVO 3501 986-8, may be this helps?
also found other bosch numbers, but just now no time to have a look at the specifications 0 280 150 725, 0 280 150 357, 0 280 150 734, 0 280 150 762 found an other volvo number: 3517572-8, but check the specifications before ordering

you are sure ? the first digit is missing and the question os if he can deliver? but all would be ok then it is also a very good price to buy
Romano - No I'm not sure,just found the add after a quick search online. It states in the add that it is for 512TR and part nr.144256.
when I have a look at this injector I can not see any bosch sign or name or number so may be chinese junk? also because of the 1 missing digit I think it is not original bosch I once baught fuel pumps from china with the bosch number announced. when I got them I tested them and they have been noisy, only about 80% delivery of this what bosch pump delivers. wanted to send back but never did because they did not want to pay the money back. this has been by alibaba. so never again ! ! ! only my own experience
I checked just now the parts numbers and the specifications 0 280 150 762 static flow at 3 bar, medium n-heptane: 150,2 gr/min, resistance: 14,5 ohm, other design outside 0 280 150 734 static flow at 3 bar, medium n-heptane: 150,2 gr/min, resistance: 15,9 ohm, same design like 0 280 150 419 0 280 150 357 can not find anything 0 280 150 725 static flow at 3 bar, medium n-heptane: 150,2 gr/min, resistance: 15,9 ohm, same design like 0 280 150 419 3517572-8 can not find anything so as I see it all are too small, the original has 155,2 gr/min
Maybe it is a good idea to write all these 512TR injector data in the cross-refrence thread Romano, can you do it ? https://www.ferrarichat.com/forum/threads/testarossa-cross-reference-thread.125008/page-13#post-145612563
those injectors I mentioned are not 100% equal to the originals. so someone may test those and after this testing ( if positive of course only ) put it in the cross reference thread I have the possibilty to test, but not have either the original nor the other injectors here
What is wrong with the original injectors? You can have them tested, cleaned and rebuilt for a very low cost. https://www.rceng.com does great work. If you need replacement injectors, they can also help you in sizing the correct injector or even making custom injectors.
