its on here, well, and on sr20forum, where another guy is attempting the same swap but in a 240sx... its me.you'll need to have access to a tig, a machine shop, and will need to do some kind of distributorless ign. running the oil line for the cam activation is the easiest part of it. fnding a good rwd shortblock was the biggest problem...i literally tried 5 times to find a good one...and ended up sleeving one with a bad cylinder wall once i couldn't.
and why not use a sr20vet from an xtrail? well, you'd have to do the same mods for rwd application anyways... they're harder to find, and way more expensive. you'd get a cast turbo exhaust manifold that can sit on a shelf in your garage once you get a custom tubular one. on the other hand the valve cover is cool...like a 20v's , and has individual coils...which you may or may not be able to use with whatever ems you choose.
