since we are just looking for a way to have our pistons pushed by cumbustion that was induced at beyond atmospheric pressures, why don't you just save time money and speeding tickets by going the chemical route. people like venom sell nitrous for cars w/o fuel return line...set it up conservative and count your left over money..er..your lower credit card statement. :o

 

um, i'm not trying to make a race car. i already hooked up nitrous in my car but decided not to use it and took it out. (anyone want to buy a NX kit?) this is about doing something for fun.

i already had a pretty fast car. i just think it would be fun to play with the engine on the xB. why not?

 

i agree... its fun-i love it, but it ain't no hot rod!

 

i'm not saying it can't be fast. i'm just saying it's not a race car. if i ever get my car to 13-14 seconds in the quarter mile without nitrous, it's going to freak a lot of people out.

 

true that...i'm not trying to be a hater or anything, i just laugh at people who have never had fast cars like you or i...and they talk about bolting on 8 grand worth of perfomance parts to a 16 grand economy car. i love fast cars and i love my scion, i just find it cheaper to distinguish the two. i hope that people build some quick scions...the platform is great..i would just rather have multiple cars that are each good at their respective jobs...just cheaper for me. btw eric, you got the tightest scion around!

 

it's not like i'm some dumb kid who is like "i'm gonna build a turbo and go fastar weee" or whatever

FASTAR!!!
I wanna buy an eric m. "FASTAR turbo for the 1nz-fe"
perhaps it could be under the "Randode Racing" halo and you guys could get rich off us hangerson.

im actually kinda serious, and if FASTAR was just a spelling error i wasn't trying to make fun. i just think phonetic spellings are funny in the right application. It makes things more conversational.[/list]

 

$8k is ridiculous to spend on the engine for this car. $2000-$2500 is also a lot but more acceptable, especially if you can get it faster than a stock wrx, Z28 camaro, mustang GT, 350Z, etc. it's kind of cool to have a sleeper sometimes.

 

Internationally, Toyota has developed a Turbo kit for this engine first. It's been sold in both Europe and Japan.

http://www.trdparts.jp/parts_vitz-turbo.html (This needs translation)

Both of these were developed for the Yaris/Vitz (Echo Hatchback), but all of the 1.5L have the same engine.

Here's a link to a 3rd party supercharger in development.

It's funny though.. they seem to max out at generating 150hp.. I'm guesing this is about the max performance boost without having to do signifcant engine/exhaust/fuel management mods.

 

50% improvment in WHP is not unusual. think about other cars. do you usually gain more than 50% over stock HP by just adding a turbo or supercharger? not usually. i think 180whp, which is pretty much doubling the stock HP is possible, but not safe on stock internals. but i'm sure someone will do it. hopefully our engines are stronger than we know. i hear that in japan the 1NZ-FE is considered one of the better 1.5l engines. but i guess we'll see.

 

Oh.. it's a great increase. Especially for me since I've got an echo weighing about 300lbs less than the Scions. It just seems that 150 is slowly emerging as the current technical limitation. A 150hp Scion/Echo would be nice and fast though. I'd like to know what kind out torque numbers it puts out.

 

Here is a good reason - Jail time! NOS is illegal in many if not most places for street use , turbos and superchargers are not.

 

i honestly don't see why nitrous oxide is so illegal. it's not flammable, and it doesn't increase emissions. it seems like everything is just illegal if it's not OEM these days.

 

:oops: Supercharge is great but at what price for the power??? Monkeywrench said the one from Japan adds 30hp for $3000 thats not a lot for the money. For $3000 dollars it better be 50-75 horespower. [/quote]

 

30hp is a lot on our little cars. on a mustang it wouldn't do much, but it would make our cars go a LOT faster. seriously.

 

yea 30hp lets do the math that is approx. a 33% increase in power now lets add aheader more gain lets just keep our eyes open and see what is offered. what about
apexi equipment eric was trying out one, how did it work? and who is doing dyno
testing after installing parts what kind of gains el prototypes had some`can some one do a feature in the news letter?

 

True 30hp is alot for are cars but for $3000. Do you think it is worth it. Putting on headers and heads,air intake is great but, add that to the price of the super charger that's a littel for alot......

 

this might be a little off topic, but here's a video of a TRD SC on a Matrix...for the price and the very significant increase of power i think its worth it ... http://www.matrixowners.com/ftopic14189.html

 

Nice Video......Its hard when you buy a supercharger for a mustang you get 50 more hp but the xb is not a 302 its a 4cly so 30hp is good i guess......The people in this fourm and on this web site kick ___ you guys are great........

 

If it's not OEM and has not gone through the CARB certification process then it isn't legal. this applies to all parts that can affect the emissions system, from the gas cap to the catalytic converter.

NOx systems haven't been singled out, they're just so far from meeting emissions standards that none of the manufacturers even makes the attempt.

NOx systems just dump fuel and oxygen into the intake and hope for the best. Since they don't want to grenade the engine they use an excess of fuel. To get the mixture right for emissions they would have to meter the fuel much more precisely, and that would cost a lot more money. The typical NOx system buyer would be unwilling to pay the added price.

Superchargers and turbochargers use the car's built-in fuel metering capabiity, so they get precise mixture control. Of course, they might exceed the stock system's ability to deliver fuel, which is usually the price break between "mild" and "wild" systems. You can get 30HP on stock components, but if you want 60 you'll have to start changing other parts of the engine and EMS.

i think the reason i think it's odd that they would be cracking down on nitrous is because you usually only use it for a couple seconds at a time, so the engine is only in that rich, heavy emissions state for a really short period of time. illegal? yes it is. but remember that there are motorcycles out there running bigger engines than we have in our scions, and they have no emissions devices, with straight pipes coming out of the exhaust manifold...and they never get in trouble for smog laws. but yeah, as far as legal issues go, of course anything you do to create more emissions, even for a second is going to be considered a crime.


also, 50hp on a V8 with 4.6 liters of displacement compared to 30hp on an inline 4 with 1.5liters of displacement. hmmm. for the mustang supercharger to be as efficient as the one we will be using, it needs to make 90hp. and their supercharger kit still costs $3000 or more.
