Help converting my gts4 NA to a turbo

[skylinegts4]

hey guys as some of you know i am selling my car but ive came to the conclusion that if i dont get rid of it in a couple of months then im going to turbo charge it.

its a rb25de 4wd. i was reading in the forums about installing a turbo in a na engine and i found out that a rb25de can handel a stock turbo at 7psi.

i need help and asking anyone out there what do i need exactly to turbo my car like manifolds etc..... im not to familar with engines so could someone please help me and tell me exactly what parts i would need so i can search for em in the forums.

do i need to change my computer and if so which one? as its a gts4 and 4wd a gtst would not be able to control a 4wd system??? or would it??

thanks guys
