In the 240SX community (which is all I know) there are mixed reviews on these manifolds. People seem to have trouble with tuning for them, mainly due to the not-the-greatest casting causing the plenum to leak under boost, while on NA motors people have experienced low and mid-range power losses (though that is to be expected without supporting mods and proper tuning).
That being said, I still bought one, mainly because it is the most economical and best-looking (in my opinion) manifold option for an RWD VE.
And not to be all negative, apparently they can perform quite well once the casting is cleaned up a bit, coupled with a good tune.
On an NA motor it should work fine just bolted on, though for any serious power application the best solution seems to be to weld the flange and plenum.
