pod filter??
haha, have a look on R31 skyline club. from what ive been told by a few people, is that when you put on the stock VLT kit, its nothing special at all compared to the NA Rb30 with some basic work done to it. id say make it a na monster or put in a 20/25.
there are so many possibilities and the potential is enormus, depends on what you want from the car!
