A couple ideas I've got to free up some ponies but I've never applied them to a 1.3L before.
hoping someone can let me know if these are done with good results on these engines.

1. Recurve distributor.
Can lighter springs be put in to bring on timing earlier in the rooms?

2. Advance the cam.
Had anyone advanced their can 4 with any gains?

3. Rocker ratio.
What is the stock rocker arm ratio?
Is there a direct bolt in higher ratio arm from another year, displacement or different engine entirely?

Thanks for any information you can provide.
