vq30de specs
 

besides bothering all of you, and short of dis-assembling my car and measuring everything, where can I find detailed information on my engine?

I'm looking for valve diameters, valve lift, cam duration, etc.

also, do any of the super-tuners know where I can get some 8000 rpm valve springs?

the fsm has it.

get the vg30de, vq30de and the vq35de and compare them, minimal changes in the engine design
