Thanks guys. NO engine conversion in the works for this car, just tidy up and use as my daily.
Might look at getting her some visual upgrades (angel eyes, clear or smoked indicators and parkers, new boot spoiler etc.) but nothing mechanical unless required.
The 325e has a 2.7lt straight 6 (only 90kW but supposedly fuel efficient and emissions friendly), feels ok power wize but the diff feels like it couldn't handle it if I gave it stick.
