Hi,
(sorry, posted this on my350z as well, really need an answer)


1) can anyone help confirm the exact kit# from Vortech for a 2003 G35 5AT coupe?

I need a complete kit (CARB approved) since this is for a California car...
I called Vortech and their sales associate is saying it should be 4NZ218-010L

but their install manual seems to indicate kit# 4NZ218-010L as being "2003-2004 Standard Engine 350Z, V-3 SC" and doesn't mention G35....

Manual also says Kit# 4NZ218-030L for is for 2003 Infiniti G35, 6-Speed (no mention of Auto Transmission)

Add to my uncertainty since their website for complete kits indicate 4NZ218-030L as being for 2003-2006 G35 non Rev UP while 4NZ218-010L only for 350Z.

the only difference in part#s between the two kits seemed to be 5A001-351 vs 5A001-354 - timing control box...?
I'm paranoid - I just want to get this ordered correctly and then worry about install and tune without missing anything critical.
relevant mods installed at this point are Transgo valve body upgrade and HKS cat-back exhaust. oil cooler has been ordered, and may go in ahead of the SC, along with upgraded radiator.

2) if I decide on getting CJM stage1 RFS along with Walbro lph 255 fuel-pump and DW600CC injectors,
- would I still be able to use the Vortech SS box? if not what would be the next step in terms of tuning? Haltech?
- would upgrading the fuel system mean I would get rid of the Vortech-provided FMU & Fuel Pump?
yes, I read through the Vortech FAQ ..all 100+ pages of it... lots to absorb... may need to re-read a few more times ...
goal is 400WHP, reliable daily driver that will pass annual smog =)

 

1. I THINK it's supposed to be 4NZ218-030L, I would call again in a day and see if you can get a different rep.

2. Uprev tune is always an option.
