Yeah I love this site, did more reading on it than I did for my masters degree and figured it was time to join
The VQ37VHR is great engine don't get me wrong, it has a variable valve lift controller (VVEL) on the intake side too which gives it a nice flat torque curve. What I don't like about it is its high static CR (11.0:1) and it's VVEL which becomes one hell of a bottle neck at high power levels. Then comes the 5speed auto with paddle shifters, they're very laggy and behave weird when the car is driven hard.
I've been in a few RB powered machines and was sold on the spot to be honest. A friend of mine will be buying the VQ37 with its transmission off me, and in will go my RB!
