and yet i digress...... NPORA has a lot of info regarding a vg30e to vg33e swap. little of it relates to the 2002 xterra/frontier vg33e, which shares the same accessory layout, but has different electrical connecters and hoses/tubing. i,ve got the same project going on now too. i'm going to use the vg30e upper intake manifold assembly and exhaust manifolds, with vg33e accessories, alternator, a/c comp and ps pump pulley. distributor spindle from vg30e fits into vg33e and hopefully will work. vg33e distributor is not compatible it seems. sure other things will come up this weekend upon install. trans should work just fine as much of the front suspension from 200 -04 xterra's. check out NPORA, they cover WD21 swaps to newer versions in detail.
