vvel delete (back to de/upgrade to gtr)

-People have upgraded to GTR's when they purchase the car.

why dont de35 and vr38 use vvel?
-DE is an older engine and engineering has a constant progression.
-GTR has VVT. not sure if it is on intake vs exhaust.


more complex compon so less realiable？
-VVEL is more complex than a standard push rod engine. VVEL does not seem to be less reliable.

There you go. Half a$$ answers to half a$$ questions.
