I just picked up my kit today. Ive got the 03 coupe. I noticed that the part number vortech sent me was for a 04 g35c(as per their web site). The place i bought it says that they are the same kit. Im gonna phone vortech tomorrow just to be sure.
Anyone know the answer?

 

I'm pretty sure the kit is the same--the only thing that *might* be different (though I doubt it) would be the programming of the fuel/timing maps that have been preloaded into the piggyback ECU. Since just about anyone here on this forum who has the Vortech installed would recommend having the piggyback box custom tuned, it's a non-issue even if it's a bit different IMO.

I have an 03 G35 and my invoice said kit for a 04 also .No problems

 

Yes they designed the kit using my 04 knowing it will work on 03 and 04.
