Hyphy Posted April 2, 2009 Report Share Posted April 2, 2009 you may wanna check with the z31 folks at z31performance.com or hybridz.org Quote Link to comment
72240z Posted April 2, 2009 Report Share Posted April 2, 2009 (edited) vg30e's came with flat top pistons with valve reliefs, vg33e's came with much larger reliefs, vg30i's came dished as did vg30et's. Villager vg30e's and some late vg33e's came non interference and have different reliefs. Edited April 2, 2009 by 72240z Quote Link to comment
a100addict Posted April 7, 2009 Author Report Share Posted April 7, 2009 thanx guys we have determined that it is a turbo block based on the oil drainback fitting on the oilpan. so it is a vg30et Quote Link to comment
SRSANDS Posted April 7, 2009 Report Share Posted April 7, 2009 Glad you found its a VG30et but dont base your finding by the oil plug on the pan.....Ive found even the non turbo cars have it there.......sorta a universal part on the VG. My pan has it too and its off a nonturbo 300zx Quote Link to comment
Hyphy Posted April 7, 2009 Report Share Posted April 7, 2009 being that you only have the short block, do you plan on building and completing the motor? If so, the differences are likey to not matter as the more critical parts are those you dont have. Intake, heads, turbo?, etc I have yet to see my block all cleaned up to find the block markings so I cant tell you where to find em, but if you have...perhaps a nissan dismantler might have the knowledge you're looking for.

yellowdatsun Posted April 14, 2009 Report Share Posted April 14, 2009 You sure it's a drain back fitting, some of the later (IE: Quest) pans came with a sending unit that looks like a drain back fitting. I have one of those. There are no actual "turbo" blocks, I believe the only difference is the pistons, as stated previously. Quote Link to comment
