The Nitrous Thread

[MiniTRD]

I am in the process of final fitment of my ZEX wet kit. It is the one I had in my tC, just rejetted for the Yaris.


Here are a couple of pics of my setup and purge

My solenoids are behind the engine, mounted on the firewall - I;ll get some close-ups pics of those and post them up.


Let me know if you have any questions

[E.R.G]

Liltoaster, which ZEX kit do you have ????? I want to use it only for drag racing. Now my best ET is 16.45. I would like to run in 15...

Thanks for the info.

How much money have you guys spent on kits?? and how many HP are you getting???

I'm getting about 145whp 160 torque (about 400 spent on parts) with spray .. hopefully will be able to get 155whp in about 2 or 3 weeks with new jets. Will post dyno sheets soon.

^^ What kit are you running wet or dry .
So far I got like $140 into my set-up which it a 10lb nitrous express bottle , with zex dry no2 selonoid a zex nozzle taped into the intake . Just about the most basic kit ever . Activated with an arming switch and push button(just like F&F lol ) jetted with a .38 which is right around 40hp . I need to dyno for the real numbers though.

VERY COOL, dual purge would be awesome there, like a ragin bull. Please tell me it lights up at night? hahahah If i get this kit im looking at that would be the perfect place for the purge, thanks for the idea :)

I was running a 55 shot on my Echo with no issues and I ran a few bottles through it :)

Dry or Wet ??? and where did you mount the nozzle (like what kind of intake and how far from the tb ) ???

[jekqmb]

Wait for Garms intake mani to come out, with bigger injectors and a tuner this car will be able to handle a 75 shot and make in the 160-170whp range with bolt-ons and nitrous. Are stock manis and injectors just cause too many problems. These cars on nitrous can be ran in the 13's if done right with a direct port setup and a 75 shot. But not with a plastic mani and are stock injectors. I have been doing a ton of research on this. Im also not new to nitrous.... my last cars setup was a dual mainline with 2 bottles and a 90 shot on a ported blower. Spraying after the MAF.......made 347whp

Never use a dry kit, your car will run way to lean and it may damage the engine, my advice, buy an APEXi AFC take it to the dyno, the yaris will definitely hold 50hp worth of nos with the correct mixture of air and fuel, i've been told it can hold 60, I have not tried this, I do know it cannot hold 75, everyone I know that has tried this have blown their engine, although I dont know if they set up the kit with the AFC. Hope this helped

I think the moral to this story, and this entire thread, is that NOS is super cool where appropriate. As much as I love my Yaris...I wouldn't spend 1k+ on installing a NOS kit and using it a handful of times. Plus if you need it to be your daily car for the next two years...this doesn't seem like a mod you'd want to make.

However...

If you've made your mind up, all the more power to ya and good luck! Post some pictures when it's all said and done!

Responding to a thread from 08, Cory? :D Fail.

Guys I need help with finishing up my NOS kit. I have a TB spacer with fogger hole coming in soon, so I'm guessing that all I'm missing is a window switch to tie everything together, right?

Unfortunately, I have no idea which one to get. Here are a few units I've come across so far (click on the images for links):

Here's the system I got from Garm (at an excellent price, BTW):


MSD Window RPM Activated Switch


NOS Fuel Injection Drive-By-Wire Wide Open Throttle Window Switches


Not sure if I need these too:
TPS VOLTAGE SENSING FULL THROTTLE ACTIVATION SWITCH


HYPERFORMANCE™ SPARK PLUGS


Any ideas? I really want to get that thing on my car.
Thanks in advance!

Bump?

I just got a vice for my machine and installed the tooling, just gotta figure out how the cam software works then i'll probably be doing the nitrous gig too with a spacer plate.

All you really need is a basic kit, purge would be nice but alot of people don't run them, and a window switch. You can never really go wrong with ZEX. But you want to make sure it activates with TPS and RPMs IE: at 90%+ Throttle Position and from 3000-200rpm before redline. And also an activation button to make sure you don't spray all day long. I doubt you want the thing to be spraying at only 40% throttle either :P

Good luck with your project!

This one looks good, i think its in your picture up there. Goes by TPS and RPM

Not sure what I'm looking at. I see a bunch of RPM chips and an "NX DIGITAL RPM WINDOW SWITCH"...

Are you saying that all I need is either an RPM chip or a window switch? If so, which RPM chip would be best? I'm thinking 3000 is pretty low, and the others are a bit high for our cars, right? Where should the chip go?

I'm a huge n00b when it comes to this, so spoon-feeding is appreciated (and encouraged).

i want to know too, my kit is going in soon
