Good to see you are still with us Sata
I,ve had a 1.9 and now got a 2.8 . Yes the 2.8 is way faster but I really think you get more fun driving any car nearer its limits. With the 2.8 you simply cant, very often, and keep your license..so don't discount 1.9. There,s a good case for many cars simply being too capable and easy fast.. Yes I know the 2 8 is no supercar but its bordering on high performance. I used to have a Westfield with around 320 bhp/ ton. It was no fun on road. Too fast, too capable and not a cruising car.Accumulated 9 points with it. Sold it. Enjoy Z3 loads more and enjoyed 1.9 as much as 2 8. Both are capable of relaxing and taking in view with occasional spirited driving .
Think pre face lift are M44 1.9 twin cam 16 v I think.
Face lift are 1.8 single cam less bhp
Iam sure someone with more knowledge will be along soon with facts and figures.
