Seriously guys...coming on Skyline forums and trying to bag Skylines? You will NEVER win....now run away with your tails between your legs to www.calairturbo.com with all the other "Fully Sick" VL crew.
First thing I would do is get rid of that horrid colour. Sounds like you have yourself a bit of a beast there.
Wouldn't mind selling my R33 and buying a worked VL Turbo...and put the change in the bank.
We have about 7 fairly new magnas/veradas here at work. Some of them have that quick shift auto trans with traction control. The 3.5 litre has plenty of torque of the mark surprisingly. To tell you the truth I'm not really surprised he beat you.
Aftermarket BOV's on a standard R33 are more trouble then they're worth. My advice would be to forget about it and get yourself a pod filter. That way you get the sound of the stock BOV and a nice induction noise.
