i believe the vq is a 3.3 not a 3.o like the vg. they have forced induction on the vq, i`m sure you know. if they didn`t stray from the bullet-proof-ness of the vg`s bottom end then it will be a contender. shit i would love to have the extra .3 for old dirty bastard, get rid of the sc and bolt on a t3/04.(cause i`m guessing it has lower compression bc of the s/c) i`m guessing the 350z motor is a vq35de. there are turbo and twin turbo kits coming out for it and the maxima is setting down some decent hp #`s for being n/a. aftermarket? seriously, how long has a big aftermarket for import been around? shouldn`t take too long, once people start moving on from rb, sr and vg (not that there`s anything wrong with those, but even ford moved on from the 5.0) then the a/m will pick up. plus these motors arn`t cheap right now, easily picked up in junkyard, bought in clips or very aboundant in wrecks. give it time... to bad nissan chose not to continue the s body here in the us.
