I have aquired a set of Heads/Cams from a 2004 Infiniti FX35. I also have a set of Heads from a 06 Infiniti M45 with the VK45DE. I was wondering if I could use the valvetrain from the V8 in the VQ35DE heads? I can also have them ported locally.

or

I also have a set of VQ35DE heads from a pathfinder and a 01 DEK motor. Can I put this together into something with the valves?

Not sure about the VK stuff but yes that would be a great NA setup. VQ35 pathy heads mate fine to the 00 VI and Id love to see what that intake yields on a full VQ35. If some DE-Ks get to 220whp, with 3.5L it would have some potential.

 

Ok with the -Ti valves sell them to me

anyways they will fit i believe the intake ones but not the exhaust ,tilley made them all fit but he said it was super loud .

I would put them in the pathy heads i believe thell work but SR once said theres a chance something may not work out maybe the retainers? but if you try them and see how they fit then well know

 

What did he do to fit the valves that made the engine louder?

 

The VK valves are 1mm smaller than the OEM 3.5's. Not worth it IMO. If you want affordable titanium valves, supertech is the way to go.

 

where are these Ti valves i checked supertech on Z-1 auto and only found there valves made from SS and inconel

 

Oh snaps, my bad...i was thinking of their retainers....
