please do a search on the forum, there are a couple of projects about at the moment with different engine conversions,
none of which are easy.
they will cost £000's of pounds and are all custom,
the easiest one is the ga16de from a primera, using the bottom brace from the primera the rest is vertualy bolt up, custom driveshafts are needed and some tweeking of the mounts..
not a job for the feint hearted. and its been covered before.
