The only way a G35 could realistically keep up with a 930 is either twin-turbo or Vortech/Procharger supercharger on a built, lower compression engine. HKS' blower only gives 45hp on a 350Z!?! so it's pretty much worthless. I'll bet the 930 would wake up a lot if you dropped in a G50 box in there. :-) Do you have stock exhaust on the 930? Taka
