Zex Nitrous Kits For 370Z?

Quicksilvers · 07-28-2017, 04:56 AM

I would like to install a Zex nitrous on my 370Z. What size hp jets can the stock VQ engine handle without damaging the engine? I am considering 125hp or 150hp jets. In the future I look forward to getting forged internals sometime but,would like to get some life out of the stock VQ engine. I plan for trips down the 1000 foot track. According to Zex you don't need a tune to run this nitrous kit? What supporting mods and fuel mods should I run with this Zex nitrous kit?

If you have to ask these questions, you are nowhere near ready to touch a nitrous system

That's a pretty good size shot on a Z, as those nitrous HP-Shots are calculated closer to RWHP.
I've heard tuning in 75 or 100 & nomal supporting mods to help.
Engine wise; external oil cooler a minimum,then there is Headers & free flowing exhaust, porting your upper & lower intakes, nice CAI,,, kinda the usual.
After you add everything up/ you're about 1/2 way towards a twin-turbo kit.
Nik@SOHO is selling his Fast Intentions TT kit installed for around 15....installed w/freshened up turbo's.

Everyone I have seen or met had single or twin turbo kit or supcharger on their 370Z I have not seen anyone with a nitrous kit yet anyway. I wanted to find out other people's experience with the Zex nitrous kit. According to Zex running their controller box and size jets you don't need to get a tune but,it is recommended. These Zex nitrous kits activate at WOT. The only nitrous kits out there that I know that are rated at the rear wheels is the Nitrous Express kit I ran this kit before on another vehicle. By upgrades I mean fuel system upgrades. What size fuel injectors and fuel pump are people running on their 370Z with a nitrous kit? I would like to run 100hp or 125hp jets safely until I install forged internals.

Maybe 1/3 of the way...pending on quality of parts.

jchammond · 07-29-2017, 09:45 PM

I've seen a few Z's dyno w/400+ rwhp...which is good; because the torque was right near it...I've been wishy-washy on this one...as in the older days; a PoP,,,was not good.
But the newer systems are designed to not work/ if all conditions aren't met.

I do know the stock VQ engines max whp you can run even with a good tune is 400-450 whp. Anything higher than 450 whp is running on borrowed time without swapping to a forged rotation assembly. This is why I am asking for advice so I don't damage my engine.

CarbonZ made 424whp with a restrictive exhaust on the nitrous express GTR plate kit. Which I'm selling If you're interested. It a also comes with 25,50,75, and 100 shot jets

No thank you I am going with a new nitrous kit. What fuel injectors and fuel pump did he run do you know? What jets did he choose to run? How did his tune go?

James,
Those jet sizes are what i've seen & i'm sure are compatible w/oem injector's & fuel system.
Up-grading the fuel system w/return lines,larger pump,injector's...would probably support more...but goes back to Quicksilver's original question.

James10694 · 07-31-2017, 02:54 PM

He was running the 125 shot. Not sure if you need larger injectors or pump, however I know you can run a 125 safely with a good tune.

NeverBoneStck · 07-31-2017, 03:02 PM

U need a bigger pump and injectors would be a good idea. I have ran through at least 60 bottles with no problems. U need colder plugs as well..
