Cam duration doesn't have a universal lift measurement location, sadly. Brand cam duration is based on "where this company measures from, and sets their own standard for all cams", so a bit of a subjective art to it. A bit weird, but true. Many companies will swear this way or that is the best way for measuring duration. I think lift is a more valuable measurement. JWT and Tomei are both top notch, you can't go wrong either way. Personally, I went with the JWT cams because I know and trust those guys and their long term experience working alongside Nissan / Nismo factory racing programs and trade secrets, especially regarding the VG / VQ platforms. I'm sure you'll have good results either way once the cam timing gets tuned in.
Currently, your dyno graph looks solid and a good start. Very curious to see how things look after tuning, especially over 6k rpm. Keep us posted!

Just been going through my mailbox today on hotmail as i have been unable to access the net for a while.
I had 3 or 4 mails form unknown senders which contained only what can be absolutly disgusting!
Where does this sick stuff come from? My mail address is only used over the forum and very few other people have it that i know of.
Anyone have any solutions as this is really annoying.
