Just for fun,
Has anyone ever swapped a '85 3.5 litre engine into a '84 732i. The original engine was overheated beyond belief and completely screwed.
The 3.5 litre engine has now been installed, having removed the electronic automatic and reinstalled the old hydraulic automatic trans.
All the ancient 732 engine electronics have also been fitted onto the newer
3.5litre engine.The ONLY problem so far is the MAF meter.
The correct 3.5 litre maf does not work with this cars computer, it will not start. The 3.2 litre maf does work with it, but as expected, in default configuration runs lean. The maf has been opened and the pressure spring loosened so as to enrichen the mixture to the correct level. I however have a feeling that, there is going to be a flat spot in acceleration somewhere up near wide open throttle due to the fact that the maf will be wide open before the throttle body hits wide open throttle.
Since the car is not licenced, i have only driven it around my street and not taken it up to full speed. With the open centre differential on the 732, there is great difficulty in not having wheel spin at take off. We will swap in the LSD shortly.
any constructive input ?
