It sure is the european TI motor - known as bmw "compact"
introduced at 1991 in 2 variation.
M43B16 - 1.6cc 102HP
M43B18 - 1.8cc 115HP - was also used in the euro specs Z3 1.8
all of the M43 engines are 8 valves. they have lower compression ratio than the 1.8 16v engine - therefore they are much more suitable for a turbo project.
there is another M43 engine known as M43B19 which was introduced in 1999 and was used in the E46/E46 compact.
