Just picked myself up a turbo off a VQ30det, and the only info i can find is that this engine is an alloy block, an update of the vg30det. A similar engine (VQ35DDE or something) is used in the 350Z. THe turbo itself is in very very good condition with minimal shaft play.
Physically the turbo is a fair bit bigger than my rb20 turbo, and it also has a Steel exhaust wheel. One weird thing is that the exhaust housing is not of the regular shape. Ill post a pic or two for viewing.
Another interesting characteristic is the exhaust flange. It is not a regular rb20/25/vg30 item.
Ill get some clearer pics tomorrow for everyone to see. Any idea what kind of power this thing is capable of? The VQ30DET engine is rated at 206kw stock.
