I have both a 32 GTR and MY2000 Manual Version R FTO at my disposal.
The FTO Ver R is the one that competes with the Integra Type R and IMHO whips it for looks, sound, modern interior, LSD, NO ABS, fr and rr strut braces etc......although not screwed together quite as well.
The FTO is better:
For attracting attention to those who dont know
Fuel consumption
Sound!!!
Seats
The GTR is better:
Grunt
Street cred to those who know.
Its a skyline
As a daily I prefer the FTO.
