I know that the Revup engines in the 05+ 6mt's lost 10 torque but gained 18 Hp. I'm just wondering what did that. I know so far it was
1. "electronic exhaust valve timing control"
2. "revised pistons"
3. "higher lift and duration camshafts"
4. Lower plenum redesigned ( http://infinitipa.zoovy.com/product/14010-AC805 )



Q1. The newly designed lower plenum in the 05's are the same price as the older design, and i'm wondering if its worth it (performance wise) to get the new lower plenum for my 04.

Q2. Where can i get valve timing components from and are these worth it as well if money wasn't a factor?

 

1. probably not

2. money not a factor... TT it, but if u want it im sure u can get it off infiniti somehow

 

jus get the half inch spacers from motordyne.. it will give u atleast 10 to 15 more horses to the wheel.. and ur baseline will b the same as a stock 05 or 06

 

stiffer rods, different ecu, rod bolts, A&F sensor?

no not worth the money
