Difference between GT-R and GT-R turbo

HELLO

Can anyone tell me the difference between the
GT-R
and
GT-R turbo
As I can't find out what it is
Also are they both twin turbo's ?
I do know the GT-R has 283 hp if i'm not mistaken
and whats the spec. on the turbo ver.
I thought they both where TT's
looking at picking a 1990 up and brining it into canada
just confused

THANKS

Basically you looked at one where the owner called it a GT-R turbo because he wants it to be known its a turbo.

All GTR's are twin turbo unless they have been modified to single turbo. I don't know why anyone would do that but they do.

single turbo is better for drag racing
