Nissan - only for the RB30 engine
Toyota for everything else
GTR's are crud - a certain race team I know owns a few and after spending $250k on 1 it still drives no better than a race ford or holden just with more power. Gearboxes cannot handle the power and the electrical system is way overcomplicated to get the consumer to just spend more money.
I will give it to Nissan in a sense that they manage to keep the hoon market alive with factory cars 180sx/silvia/skyline alongside Honda (cannon exhaust - dropped on their guts, sounding like multiple wet farts screaming along


)
