No, the Skyline uses an inline six...

An inline six is quite different from a V6 because of cylinder placement. The "V" denotes the basic shape of the engine, with each bank of (in this case 3) cylinders basically mirroring the other 3. From the top view, it would look like this: ((The crankshaft would be running through where the hyphens are)

1 - 2
3 - 4 (I'm not going to bother mentioning firing order)
5 - 6

Here's a better picture:

While on the other hand, and inline six would look like this:
(The crankshaft runs parallel to the cylkinders, directly underneath them)

1
2
3
4
5
6

Like so:

Also, there are other types such as newer-style "W" engines and flat (horizontally opposed) engines.

I hope this clears things up a bit.
