Cheap and easy efi 1.3 upgrades?

[Dragonhealer]

"Cheap" like milling a head (but you have to buy a gasket, expensive) or "easy" drop it off with your favorite builder
with a box of cash.
Beyond the tweaks the guys have noted, the simplest is the Capri swap, keep your trans, the car will be a hoot to
drive and will run even on the poorest gasoline.
You can substitute a 1600 Miata motor but will need come Capri parts for ease and simplicity.
It's not better than sex. but it will put the same grin on your face.

Yeah, and you can do it to as many Festivas as you like without the negative moral repercussions. In fact, the more you've done it to, the better it gets and people tend to hold you at higher regard. :p
