Got the tsuru kit but am goin to add HID,witch color should I choose?

I would go with the crystal purple. I love the way the BMW's and lincolns and other luxury cars lights look. And when you see those lights coming down the road you know its a luxury car with H.I.D., not some civic with APC "hyper white" (which is just blue), Ya dig?

Yea your right ,everytime I see those type of lights I think its a luxury car.I would love to see the look on peoples faces to see its a sweet sentra.

I would stay with "non tinted" HIDs. Most higher Kelvin (color temp) HIDs comes with tinted bulbs. Higher you go, lower benefit you get (harder to see in bad weather, etc).
I have 4100K Bosch HIDs on my projector lamps. even that low number, they look purplish blue from far away. I think it depends on the type of reflector housing you have. Not your bulb color temperture. 6000K would look awesome, but I was just trying to give this info you might want to know.

Yo,thanks for the info and by the way your car is tight!!!!!!!
