Looking through my old South African CAR mags and found this classic test of a tuned TURBO version one of THE cult cars of the early 90's, the BMW 325iS. It effectively was a hotted up 325i, first using the slightly modified 2.5ltr straight six (first edition had 126kW) and subsequently through the years the engine grew to 2.7ltr and finally 155kW, to overtake the 333i as the most powerful E30 produced in South Africa, although it was slightly slower than the 333i when road tested.
This Turbo version had a huge power leap to 210kw and as you can imagine it provided plenty of poke at the time!
