SR20DET seems to be the best swap in terms of ease(ish) and massive HP gains but the most common larger swap is the CGA3 1.4 but thats still a Micra engine.
BMW engined one in Germany I do believe, plus if I'm not wrong and evo engined one. Ca18 in the black pickup with the green stickers and rear cage. There was one with a saab b204 but that was the epitome of dodgy.
