Hey guys, I have some specific questions about the VQ35DE.

What is the TB size for a 2003 VQ35DE?

What is the intake runner length?

Also, if someone can answer these questions that would be great:

1. Intake cam's duration
2. Details on the variable valve timing, is it double or single? Constantly variable or on/off? What changes and what RPM it occurs.
3. Distance from valve head to TB for each cylinder.
4. Diameter of each port, does it have air horns like the M5? Does the size change?
5. Degree of bends from valve head to TB.

Thanks

 

According to yrou Sig you own a 2003. Why don't you take your own measurements?

Then you will know it's right.

Don't try to re-invent the wheel.

 

I'm not around my car at the moment (away for a few days), and I'm not exactly sure how to do it.
