why the vq30de-k? the vq30de has standard intake manifold unlike the variable intake manifold on the k which uses a solenoid to open/close... I'm thinking the earlier vq30de's are better candidates because they are plentiful, cheap and don't use any variable intake manifolds, so complexity is down to a minimum, since you are going turbo. They are extremely cheap and a couple of guys are seeing 500whp on stock blocks. I assume that if you can mate a vq30de-k to a z33 6speed, then this should be possible(the only difference between the two is the manifold and a more aggressive cam on the k)
