The Miata engine I bought ended up needing too much work, so I found another Capri this week, this time running and driving with a big nose engine for only $400. The guy that had it quit driving it after it wouldn't pass inspection due to the taillight sockets being messed up and it not idling. The idle problem ended up just being a cracked intake boot between the air flow meter and throttle body, throwing off the amount of air going through the AFM. The interior is rough and the quarters are rusty so I'll pull the engine for the red car since it runs good and part out/scrap the rest.
Test drive vid. It makes around 90-100 hp stock and the Capri weighs 700 pounds more than a Festiva. It should make 150ish in the Festiva and rev to 8,000 rpm so it'll be a bit quicker once swapped over.
