im curious, cuz i found a good deal on a nx nitrous kit but the only thing is that it hooks up to the TPS. so do our TBI's have that TPS? also i know i would need that adaptor plate as well.

 

Every fuel injected vehcile ever created by man has some sort of TPS. What is the problem with the NO2 kit and the TPS?

 

their is no problem, i was just making sure that my TBI has a TPS< cuz the guy im buying from said as long as i have TPS and 2 stage cooler plugs, im good to go.

this is a vex system btw.

 

Is it a kit desinged for TBI? If not I would be carefull. Your car is not like every other multi port GM car than can be fitted with genmeric wet flow or dry injected NO2 systems. My geuss is that this is just a random kit that has nothing to do with TBI. Especially if he had to ask you if you had a TPS. What kind of car did this come off of?

 

its coming off a newer mustang.

he said if my car has TPS then it will work fine, i checked the zex website and they say that their systems are pretty universal.

its electronic and u hook it up to the TPS and when its full throttle, the nitrous lets go into the engine

all it seems i have to buy is the TBI injector plate so i can hook the hose up to that

 

Well the mustang set-up is for a multi port system. Is it desing to be for a wet flow type FI stystem. There will be some serious fab work to make this happen. Do you have the necessary mods to prevent NO2 from blowing up your car? I would not buy it at all. Not everything is a good buy.

 

well all it is, is a single hose that runs into his intake and then i dont know from their. i figure i just buy the tbi injector plate and run the hose to that and be good to go. if worst came to worst, i could always sell it locally or ebay it.

 

Sounds like a dry system then...make sure to bump your fuel pressure up quite a bit..

 

lol, hes going to have to do more then bump up his fuel pressure.

 

Yea he is

 

like what? zex says this will work fine with stock systems as long as i dont use too big a jet.

also i know i need 2 stage colder spark plugs and retard my timing 2 degrees he said.

i bought the system today and i am happy with it. just waiting to get the tbi plate and sparkplugs next friday

 

You are going to need Much more fuel along with that shot of nitrous. If you do what you're proposing now you will surely burn up the engine.

 

The NX tbi kits are just like any other fuel injected kit they make. It has shark nozzles that spray fuel and nitrous into the intake tract. It's not a plate system and is no different than any other non direct port efi system. The kit you bought should work fine.

 

Are you saying it already has a FMU in the kit? If I were him I would make sure of that, he just didn't seem to know enough details on it and enough general knowledge to just be shooting nitrous into the engine.

 

the nx "shark" nozzle directs both fuel and nitrous. If it's a shark nozzle, and it prolly is, which has 2 tubes that y into 1 then it's a wet system and should be just fine.

 

yes, coming out of the control box, their are two tubes that link into one. only problem is, i dunno where to put that one tube :P lmao i am soo dumb sometimes. same with the TPS wire. if you feel pity for me, feel free to direct me where i plug these things into

 

well with the shark nozzle, you could do it like nx does with their tbi kits and drill a hole in the gold spacer ring and screw the nozzle in.

 

So how would he inject both fuel and nirtrous? Most wet systems have a 9th injector. TBI is tricky. He will need the plate to make it work. That way the juice mixes with the fuel right after it is injected into the plenum.

 

yes i was thinking that too.. i might wait until i can afford the plate. orr i might get anxious and drill the hole.. hmm i dunno lol

 

You need the plate. "ghetto rigging" any nitrous kit is is a recipe for disaster.

 

hmm hmm who to trust.. 25thrss or shiftycapone lol

 

Just like I said above. You don't need a plate. The nx tbi kit has no plate. It simple has shark nozzles that spray into the intake track. A shark nozzle sprays both fuel and nitrous.

 

I'm just telling you how NX does their kit. It's not much different than any other non direct port setup I've seen. It's got nozzles that spray both nitrous AND fuel into the intake. No plate involved at all.

 

umm got a picture of this setup? cuz i want to make sure im doing this all right.

how does this add fuel to the injection as well?

 

I'll try to find a pic. It doesn't add fuel to the injection, it adds it through the nozzle. That's what the 2 lines are for. 1 is the fuel and the other is for nitrous.

 

hey i just noticed something, you are refering to nx. that is not the same brand as 'zex' is it?

 

lol, no, you said nx in your first post.

 

So do you tap into the feed line for the shark nozzel?

 

I found a pic of what I was talking about, but now that you said zex, I wouldn't have a clue if it would work or not with their controller.

i said vex, i ment zex. hmm are you familiar with zex then?


here is a pic how mine is currently set up

 

fuel feed line? If so, yeap. You got it.

 

 

oh ****, u proved me wrong, sorry . dont know why the hell i was thinking nx...

 

lol, it's all good. I'de contact Zex on that one because I have no idea what that controller does.

 

well i believe with the TBI injector plate. i just put the correct hp jet in the tip of the feed line, and screw it into the injector plate. and when the box reads full throttle at the TPS, it releases the giggle juice. sound good?

 

Is that based off of the stock pump pressue? That seems aweful dangerous to have un-metered flow to the nozzel.

 

It's not unmetered flow, there is a fuel jet. And yes, that is based off the stock pump. They do it the same way almost all nitrous kits do, except with nozzles and not plates.

 

Okay I gottcha. I know nost kits assume you are stock. Even witht the jets an aftermarket pump could cause probelms. But now I am understanding what you are explaning.

 

now back on topic :P lol j/k

 

We are on topic

 

actually we have gone off topic from the title lol, but its all good..

i just need to figure where to hook up this tps wire and where this big tube goes lol

 

I understand, but it hard to tell you what you need to do with vague words and decriptions. We are trying to visualize exactly what you have. Can you get a pic?

 

i dunt have a camera so i drew a picture. this is as how it currently sits in my car.

 

does that pic help?

 

well i know where the TPS goes, but where can i route that hose? thanks!

 

That is a rough pic but let me look at it for a bit.

 

i have every line labeled as it shows exactly on the control box. the words that are printed are only what i have to show. but thanks for looking at it and what you can come up with.

 

Well I am clueless now. I have never hooked up a No2 kit to a TBI system no less modify a multi port one to work. I would imagine the control boxes are different as well.

 

what it looks like i will have to do, because of another post i started, if i dont connect that tube, im gonna go lean, so im assuming i will have to buy the parts from nos to make it TBI friendly?

 

i remmeber you had a article on an adjustable fuel pressure regulator.. if i increased my fuel pressure and ran the nitrous. would that still be too lean? maybe i could adjust it high pressure for the racing and when i dont plan to use it, set the pressure back down?
