What the hell is with this car?

Hi gang, first time poster...and first time visitor as well.

I'm the proud owner of a 1984 Nissan Gazelle, it's in incredibly good condition for its age (I'm only a year older than it but the car has less damage). I bought it as a rolling shell, the previous owner blew up the engine (trying to drift it - good for him!) so he stripped the entire car back to the shell, then got bored and sold it to me. 100 Aussie dollars later, it's mine, all mine...

I'm planning a CA18DET conversion for it and so forth, which shouldn't be too hard since the engine bay is currently emptier than Mother Hubbard's cupboard.

However, my more immediate problem is this. The guy I bought it off left the car on a set of 13"x5.5" rims and 175/70/13 tyres. I -know- these aren't the stock Nissan wheels & rubber, because there's no way Nissan would leave that much gap between the black stuff and the guards. You could park another car in there! So what I'm asking is, what size are the stock wheels on the '84 S12 Silvia, what's the offset, and also what's the size of the stock tyres. I've searched the forums but I haven't found anything, only questions about getting bigger rims and lower profile tyres. Which I'll do further down the track.

Thanks.

std on the mk1 is 14in i think they are 5.5in wide

Thanks man.

You wouldn't happen to know what tyres and offset those wheels run would you?

i have some stockies up the back, i will check the offset tomorrow after work

You're a legend mate, thanks a lot.
