Dear all,
As far as I know, some of the E 30 325 in USA came with eta 2.7 engines. UK didnt have a 327 or 325 eta, the eta engine there was only available with the E28 525e. Not sure about other right hand rive markets.
Having said that, the trend in UK in modifying the 325 E30 is to mate an eta 2.7 block with the 325 head to give a high revving powerful 2.7 engine (see the current Total BMW magazine).
If anyone knows where to source a 2.7 block, let me know...
