^^ You just 'over love' the car too much Johnny!
IMO Nick...
The R34 GTR is newer then the R32 GTR so it's going to be refined in many ways.
Having driven both, stock for stock, they are both good cars to drive but improvements would have been done with the R34 GTR though out the years, making it a 'smoother' car to drive.
Unless you can find a R32 GTR in mint condition and have kept up the service and maintenance to match a R34 GTR, there is no way you can compare the both.
Refinements which add to a better drive for the R34 GTR is to do with the engine with slight tweaks here and there.
Aero dynamics, front and rear defuses help the R34 GTR travel smoother.
Larger Brembo brakes (compared to the R32 GTR Nissan brakes) will help the car stop quicker.
Newer suspension on the R34 GTR = Smoother ride.
6 Speed Getrag gearbox ha a smoother gear change (I think so but not by much)
All adds up.
The R32 GTR has this 'raw' power feeling, you can feel the car where as the R34 GTR is so smooth it feels a lot more subtle yet the power is still there.
