was just some tongue in cheek stirring, nothing meant by it, i acutlaly thought u used c16 for that time, my bad.
the point with the r31 times was just an example that rb30E bottom end is just as strong and can take just as much power. im sure there are examples both ways however.
i have a RB30E+T, its done 200,000k's, gives me 10L/100k's fuel economy, has shit loads of torque and makes ~160rwkw everyday.
both motors are reliable, and ull make your 180rwkw on stock turbo/injectors, the only real difference is slight cost difference, and the feel of the motor
go for a drive in both and see which u like, the torque of the 30, or the revabilitly of the 25.
