As I have said previously, I replaced my 1600 Nord motor with a TS Bosch 4.1 Motronic standard set up. The original motor produced 110BHP at 21MPG on lead replacement fuel. The TS produces about 150BHP at 34MPG on unleaded fuel. You can chat about figures & tuning all day long. Do you want to use it on the street? If so the TS with std EFI is a no brainer. Its smooth powerful & efficient. With the 2000 LSD it hits 120mph easily. Mine cost me £90.00 on e bay It has covered 56k miles from new & runs like a dream. If you want to go racing the alfaholics route is proven.
