not the Isetta, the 700 did the trick...
and while the 2002 emerged in 1968, with 100 BHP, the 1602 TI was already available earlier with 105 BHP. The 2002 TI and Tii (Injection replacing the carburettors) were not the main 02 cars, the simple 2002 was.
The 2000 engine is actually the same block as the 1602, so it was not too difficult to put it into the 2002. (Underneath the front parts of the four door 1800-2000 was virtually similar to the 2-door version).
I think it is a bit overstating to hold Hoffmann responsilbe for the 2002.
