vg30 ???

[a100addict]

i have a freshly built vg30. only the short block. what is the diff between turbo and na motors. an heads on a turbo block?thanx dave

just the pistons unfortunately, the turbo ones have less comp.

yep the pistons are all thats different. However, not all blocks and heads are the same. The W-series blocks and heads are often found in pickups/pathifnders/200sx's, and late 80's early 90s maximas. They're much rarer to find in 300zx's because the 4/87-89 cars are harder to find these days. Now it sounds like it might be hard to find out where this one came from. Take a pic of the block where the coolant passages are for the heads and we should be able to tell you which version you have. peace.

Do you have a link that describes the differences in these castings? What is the W block?

nismo, are the w series block and heads better becuase of the extra cooling?

[nismopu]

They're better because of full floating wrist pins and thats about it. So, essentially if you were to go crazy all out you could run all the internals from a vg30dett without mods. That would just add weight, but would make it capable of handling 522hp. I don't think your going turbo though, are you? peace.
