MWAHAHAHAHA

[ChinoCharles]

Today.

Summit Racing.

Nitrous.

My Yaris.

Watch this shit.

:evil:

What can I say... I'm bored with 90 HP.

[largeorangefont]

Be careful. I wouldn't do anything more than a 50 shot. You gonna have any way of tuning it? If not you will probably want to go with a wet system.

[sqcomp]

Take it to a good shop to have them install it. It wouldn't hurt to sit down and have a nice long talk with the shop about what needs to happen to make the power safely. Dataloging is a good idea.

[ROCKLANDTOYOTA]

50 might even be too much. NOS rule of thumb is get a shot that is 1/2 of your cars horsepower.

[eTiMaGo]

I need NOS... Two bottles... The big ones... so I can be faster and furiouser but maybe get danger to my manifold and the floorboards will fall off...

:biggrin:

Jokes aside, this could be interesting, please please take in in-car video!

[ChinoCharles]

OK, so here's my saga.

Last night I came to the decision that nitrous is a good step for this car. Everyone wants reliable power for a low price. A lot of us have mentioned having something that can be turned on or off so the car can exist as a daily driver while still being fun at the track. There hasn't been much talk of nitrous because, well, its nitrous. You love it or you hate it. My thinking is that I was in the market for the cheapest way to 140 HP and this is it. Someone has to be the test bunny, right?

This, of course, means that any time my car has to go into service I get to spend hours making it at least look like it might be stock again. Lets hope that Toyota reliability is all its cracked up to be. The goal then was to have the kit in the car in 24 hours. Total cost would be $569 + tax and a full bottle. It is a ZEX 50 shot dry universal nitrous system... picture below.

3597

ZEX dry nitrous systems feature an "Active Fuel Control" that reads bottle pressure and adjusts fuel enrichment to give optimum power safely at all bottle pressures. In addition, their exclusive throttle-position sensor switch "learns" the voltage curve of the engine's throttle position sensor, to activate the system at wide-open throttle every time. ZEX systems come pre-assembled and tested, so you know they'll work right out of the box, and you can install them quickly--there are no brackets to install or microswitches to adjust, and jet changes are simple.

It comes with a couple features that make it relatively safe. It is nothing I am going to really be able to use at low RPM. However, on the freeway if you're cruising next to me at 60 MPH and I want to run, I'll flip a switch on the dash, sink into third and if your car is anywhere near slow, I'm gone.

Summit Racing, 11 AM this morning... I walk in with my wallet in my hoodie pocket in anticipation of immediate use. Then we get to the desk and are told they aren't in stock. Its on display in the store, but it isn't in stock. 1-2 week delivery time. F#&*@^%@^#$

So I got a hold of Chris right away and told him I am going to need the bits and pieces of that hacked up Scion xA intake overnighted so I can weld up a custom short ram in time for the arrival of the kit. I was going to buy the ZEX filter and mount that, but if I have at least two weeks to stew on this I'll try and keep it interesting. I'll throw a K&N filter on the end and when the nitrous gets here, I'll tap the top of the filter. Booya. Then I get to take the car out on the road and test it once. Freeway after the engine has had a chance to warm up. After that I turn the system off until I can get to the dyno and work out an exhaust. It may be test pipe time.

In lieu of the nitrous, I got down on my car today anyway. I installed the tach (which looks amazing by the way, pics soon) and I installed the shark fin and the header again. Oh, and I did some... um... rearranging of the stock intake. Lets just say shes breathing nice and easy now. It has some zip already. I'm going to see where this goes... worse case scenario, you'll see a classified ad for a cheap ZEX kit soon. :rolleyes: I love being young and stupid. :drinking:

[ChinoCharles]

Be careful. I wouldn't do anything more than a 50 shot. You gonna have any way of tuning it? If not you will probably want to go with a wet system.

I am comfortable with a 50 shot as long as it isn't used daily. I don't want to damage the engine anymore than necessary. This will be for sparse track use and the extremely rare personal joyride.

As far as wet vs. dry, I agree that a wet system would be ideal. The problem is that the location of the hardware is so touchy. You're talking about tapping the manifold... but if you don't tap it just right, you're screwed. Fuel puddling in the cylinder... bad. The dry system is more straightforward, cheaper, and comes with enough safety features to allow me to sleep at night. On a side note, the descriptions for Holley kits often say dry systems are better for N/A cars and wet systems are better for FI applications. Just a thought.

50 might even be too much. NOS rule of thumb is get a shot that is 1/2 of your cars horsepower.

I would bet a mint I am hovering right around 100 WHP right now, without any exhaust mods past the header. With an exhaust and the finished intake, I'm hoping for 105 to the wheels as a daily driver and 150 or so w/ spray.

If you guys see a major flaw in this formula, help me out and speak up. I'll be referring this thread to the parties involved, and I've got a few days to change the plan if I want.

[ChinoCharles]

Here are some nifty pictures of my trek yesterday.

First, Summit Racing had two cars on the rollers in the front of the store as they usually do on the weekends. The first is a stock car... must be raced around here because it is sponsored by Tallmadge Asphalt.

3600

The second car, a Jerry Bickel drag Camaro. :drool:

3601

If you guys want to know why Summit is so great, just look at their gauge aisle. This is only a small fraction of what they offer through their catalogs.

3602

This is an example of the gauges I would like to purchase for voltage, water temp, fuel pressure and AFR. Hopefully I can find these in blue.

3603

Now my installs. First, the tach. Looks great... matches the interior perfect and really looks like the car could have come with it. We didn't pussyfoot around with the install either. Rubber gromit, heatshrink, the works... none of that exposed wire you saw on the DIY. :rolleyes: I was a little disappointed to turn it on and find that the lighting didn't match the lighting on the speedo... it isn't LED. Its OK, eventually I am going to look at changing that. Oh, and the blue condom to fit over the light combined with the yellowish light it came with make a blue-green identical to the tick marks on the stock speedo, so in that way it can REALLY look OEM for those of you interested. Ideally I want to change that light to an LED and go with blue, but for now it works for me.

3604

3605

Second, the shark fin... makes the car look a lot cleaner. I didn't realize how big of an aesthetic difference it would make until I saw it on the car. Couldn't be happier with this.

3606

Third was the header... you guys have seen it, not much to say there. The fourth, however, is hilarious. Hey guys, want 5-10 HP for free? Remove the stock air box and take it apart. The first thing you'll see is a filter with what looks like black rice in it. It is something carbon based and is for emissions. CUT IT OUT! Second, cut a hole in the airbox before the filter and cover it with some kind of screen to keep something huge from kicking up in there. I didn't bother with this because my intake parts come tomorrow, but seriously... with that filter removed and the air box flowing the car sounds like a beast! Its hilarious! Of course, visits to the dealer will never be the same. You'll have to do some risk assesment on your own. 50 miles on the car with this mod and no CEL's.

3607

[CASTREX]

You're getting crazy dude! :biggrin:

[KSIbucky]

how much would a wet system cost? has anyone seen those cheap like 25 dollar systems for regulating the NOS?

[ChinoCharles]

Wet and dry systems generally cost the same amount of money. If you buy one and decide you want the other, a kit to convert wet to dry or vice versa is usually no more than a couple hundred bucks.

Expect to pay 450-600 for a nitrous kit for this car. I actually found this ZEX kit on Ebay for $435 shipped! That is crazy cheap!

You don't need anything more than what comes with a kit, but unless you add some other goodies (fuel pressure regulator/nitrous controller/proper gauges/intake and exhaust) you have to be careful about how you use the system. For example, if you're flooring it with a TP-controlled nitrous system engaged and you hit the rev limit, guess what... your nitrous system is still spraying, and you probably just blew your shit up.

This one isn't for the faint of heart.

You need a window switch to solve that issue.

It should be fun, just be careful you don't burn it up. I'd see if you can get a wideband to dial it in and at least check to make sure everything is ok once you start spraying.

Good to know that i'am not the only one removing things of the car (ex. air filter). This cars are so limited that any stupid mod make a difference. It might sound weird but when I remove the air filter and the elbow that goes from the air filter box up (whatever this is call its just a piece o plastic that search for air) and ran my car without muffler besides all the noise the car made ( sounds great) it actually improved something and I actually felt it. Specially around 3,500 rpm. And mpg loss?? who cares it still gives more than 30mpg :biggrin:

It really can. I have around $200 in speed mods. That is it... everything else was either free or is adding weight! :bellyroll: But I still clocked myself in the mid 9's tonight 0-60 on stock rubbers in the freezing cold. Its on video, but its terrible quality and has no sound. I'll have to work on that. I'll pull an 8 in the summer without the gofast juice. JUST WATCH! My hubcaps are coming... thats, like, 4 HP.

Ashley, I just found that ZEX makes a window switch today. I was confused when I found it because it is very simple and inexpensive, but it doesn't include the TPS or the active fuel control feature because its built into their kits! Every other company is charging 500 bucks for just the bottles, lines and jets... then charging 500 on top of it for these enormous control pads. With ZEX it will be about $250 cheaper to get the same features and there is less stuff exposed in the car that lets people know what I'm hiding.

They also sell a kit with a purge system, bottle blanket and remote valve opener. Purge kit... :drool:. Don't think for a second if I put nitrous in my car I'm going to go spraying all over town. And of course I will not run this system without getting it to a dyno. I've made up my mind on that one.

How about.... BOTH???!?!?!?! :evil:

if a 5-6psi turbo came first... and the car ran well... n20 would be inevitable.

I'd really like to DIY a kit, I know it canbe done cheaply... just a matter of getting all the info required to make it happen, turbo headers would be nice too :)

Now that I can live with!

You could definitely source out a 5-6psi turbo for the same $ or even less without a doubt.

I don't doubt it a bit, but I promise you it'll be harder to install. It doesn't matter how you go fast in a Yaris, whether you're the type that pays 3500 for the reputable manufacturer turbo... or you're the type that spends 1000 and doctors up his own low-comp turbo... or if you spend 1000 on the "other" tank of gas. The point is we all want to go faster in our Yarrari. They are great cars, but off the lot this thing is short of exciting in the fast category. I want to get there as quickly and safely as possible without breaking the bank, and I feel somewhat betrayed by the aftermarket in that everything for such a little, simple car is so expensive. This car isn't a pandora's box of tomorrow's technology... it has some quirks, but you can work them out. If I can build an intake in 24 hours with 100 bucks, why the F*#& can't I buy one mass produced for less than 200% of that?!

Stock is no more folks.

3657

I think I am just going to leave it like this. I mean, it really opens up my top end.

... just kidding. Here is the finished product.

50 miles, NO CHECK ENGINE LIGHT. :headbang: I'll give it a few days before I say we've got the design down pat. I have big plans for little betty.

nice... that's about as short as you can get, good job.

now go back and dyno it! :biggrin:

[eco]

Chino,your doing great work man,keep the info coming,and I just might buy a betty from you.

[sqcomp]

CC,

I've seen this a couple times..not on a Yaris...how's the throttle response?

[ChinoCharles]

Haha, oh John... you and your intelligent questions.

Of course it isn't all good news here. As we all know by now, there is a give and take with all aspiration mods. Sure, pop a 3" intake on a car like this and throttle response will suffer a TAD. Is it noticable? Barely. Does the rest of the powerband make up for it and then some? I'd bet my testicles on it.

[acrbill]

How is the extra fuel added?

[sqcomp]

CC,

Honestly I thought your throttle respnse would be better! It was when I did the CAI on my SRT. This blows my mind. Are you thinking about boring out your T/B? Speaking of...what is the ID of our T/Bs? Anyone? Bueller?

[ChinoCharles]

CC,

Its exactly like what I was saying about the exhaust the other day. This engine doesn't make enough power YET to make use of an intake like this at low RPM's, but at high loads it should help out quite a bit. I've got my fingers crossed that the dyno shop actually e-mails me back today.

Boring out the throttle body, eh? Maybe... how about ITB's. A sprayed built N/A Yaris... MWAHAHA.

[acrbill]

seriously though... How is the extra fuel added? Any dry kit I have ever seen bumps the fuel pressure by squeezing off the return line. Since the Yaris has a returnless fuel system I was wondering how it works.

[sqcomp]

Oh $hit!? How does the fuel system work? No return line, eh? Neat. Can someone walk me through how this works?

[cdydjded]

You can not use a dry kit with a car that uses a returnless fuel systems. Dry kits add additional fuel through the factory FPR. Our cars have the FPR in the tank. Wet is the only way to go.

[LVAquaman]

I think we need to organize an intervention on ol' Chino here. :wink:

:burnrubber: Mr. Charles, please put down the wrench and step away from the Yaris before someone gets hurt.

[ChinoCharles]

Never!

[eTiMaGo]

no pain, no gain, right? :biggrin:

Someone has to be the fall boy.

You're a bunch of wussies. You guys do realize if I got in a bind I could have my car back to stock in a day, right? :laugh:

:biggrin:

[ChinoCharles]

ROFL!

We're gonna have to look into this FPR issue. Thanks to everyone who brought it to my attention. I'm sure the dyno guys will have more to add this weekend.

[acrbill]

Your best bet will be to return the dry kit and get a wet kit. Either that or run some sort of piggy back fuel computer. Thats not really an economical choice though.

Whatever you do, do not install the kit because you won't be able to return it.

[largeorangefont]

ROFL!

What was stated before was not entirely accurate. Just because it is returnless dosen't mean you can't run a dry system. You do need more fuel, but you just go about it a different way with a returnless system.

You might be able to run a boost a pump, and\or larger injectors. Possibly you will need a better fuel pump. One or all of those may give you the headroom in the fuel system you need.

The car will need to be tuned for the 50 shot or you will probably burn it up. If you aren't gonna tune it, you will need the wet kit, and use the fuel jets to tune the mixture. In that case you will need the fuel mods anyway.

There is a slim possibility that you have the headroom in the fuel system as it sits. Stranger things have happened, but cars are rarely equipped to handle 50% more HP.

First of all, I cancelled the order on the kit. Don't get too excited... I'm focusing on that intake right now, and I plan on taking the profits and buying the full ZEX setup. If that kit was in their store on that day, I'd probably be knee-deep troubleshooting it right now, so I guess it was for the best.

In the meantime, keep this dialogue going. I want to have a damn good understanding of what I'm facing. That ZEX kit was cake to install in a CRX, but it ain't 1999 anymore.

Ashley, thank you for the clarification. I live in car part heaven so I'm sure we can look at swapping a honda/acura fuel pump into the Yar... if they don't make one for the 1NZ already, which I'm betting they do. Those Scion kids like their horsepower.

Glad to hear that you nixed the nitrous for now. Its really not a worthwhile mod.
Even with a 50 shot you will still have a 16 second car at best. Add to that, the $50 per refill and it just doesn't make sense.

If you want more power you should consider a complete supercharger kit. They seem like a lot of loot at first but since it is complete its worth it in the long run IMO. Nitrous kits add up fast. Besides the refills you will find yourself buying other bits like remote openers and purge kits. Yet another thing to think about is when you plan on using it. Say you plan on using it at the strip or you feel like making a few stoplight runs. You are going to plan for this and have the tank filled with premium. Running around town with premium in a car designed for regular will cost you MPG and HP.

I find the best way to buy big mods is to slap it on a credit card and then do a balance transfer to another car that offers 0% on transfers. That way you can enjoy the part as you are paying it off, plus you don't have to worry about getting nailed with interest. The worst case scenario is that the payments are too much after awhile and you have to take it off and sell it.

Just some food for thought.

I'm sure some other fuel pump will drop in. It is just gonna take some research to see what the stock one flows and go from there.

Who said I nixed it? Its just on hold.

If you think my reasoning for doing this is really to go fast, you're in the dark. If I wanted to go fast, I'd buy a bike. This is about this car.

That's right, another Yaris pimp here ladies and gentlemen :biggrin:

WTF? If your not using it to go faster then what are you using it for?

Good luck with whatever you do.

Chino's got a line hooked up to a mask that straps on his nose. He thinks he's going faster AND he get's laughs at the same time. I dunno, I can prolly get you hooked up with nitrous for less that $50 a charge. I'll just ask my wife at the Dental office.

Picture it...CC with a dental nitrous nosepiece...

Chino, I need to talk to you when you get a chance alright.

[ChinoCharles]

Alright Steve, I'm headed to work right this second and I'll be running around all night but I can get back at you tomorrow. Either drop me a PM or PM me and ask for my cell.

[KSIbucky]

also what about a carburetor and new spark plugs and new plug leads is the fuel pump strong enough the head gaskets and maybe pistons idk

[eTiMaGo]

oh yes we definitely need a couple of side-draught Weber carburetors.

Don't forget a new spark plug distributor cap, that should help!

:biggrin::laugh:

Before anyone takes this seriously, those are engine components that are no longer used in modern cars like ours.

Funny shit Thomas Chino, Mark and I were all having a Ohio Yaris Powwow at Summit Racing, all I found there was a can of Night shades to smoke my tails
