Alternator direction
How do you know what direction your alternator is designed to run? I need to find a replacement smaller one but i am not sure the OE direction. Is it
looking at the front of the engine crank pulley or from the rear of the alternator?
What size can i go down to Amps wise for a 2L turbo?

Alternators run clockwise when viewed from the front same as most engines (with the exception of a few Honda's).

I am fairly sure that they can run in either direction. The fan may not work so well though.

They can, and yes the fan needs changing.
Straight 6 E Types with Aircon had the alternator mounted the opposite way, pulley facing the driver, to fit the air con pump in.

Fuel injection system takes a fair current but by modern tin top standards you don't need a big alternator 40 amps is more than enough.
If you have carbs you can go even smaller.

It's just starting and lights I'd need it for. Are there any the people use because they are small?

Nippon Denso from a Diahatsu Charade is a popular choice, sorry I never did establish the model number, but its running fine on my E Type.
