How strong is this engine?

[UndefinedDesign]

Has there been any Vitz/Yaris with bolt-ons? I've seen a BestMotoring International with a supercharged Vitz RS... which would be sweet to have. Can this engine take performance mods well?

[VitzBoy]

Yup, TRD has a turbo Vitz :eyebulge:

And here's the C-One Vitz (not sure what engine mods it has)

The US spec uses the same engine as the Scion Xa/Xb and there are supercharger and turbo kits for them. The greddy turbo kit is also mounted so that if you dont want to run a fmic you can run a tmic since the turbo aims up towards the top of the engine and the intake is on the other side.

[echo_hrs]

The engine handles boost ok, as long as boost is kept around 6 psi...EL Prototypes did a lot of testing trying to boost the 1NZ-FE and found the internals weak above that...

Toyota Canada has done up TTE (Toyota Team Europe) Supercharged versions of the Gen 1 Yaris, and is currently showing a current Gen 2 Yaris with a TTE supercharger in it as well...

TTE has done superchargers in europe on the Gen 1 Yaris...

TRD used to do a factory turbocharged Gen 1 Vitz, as well as a bolt on Supercharger, which is the same as the TTE/Blitz unit...

well the car is super cheap so upgrading internals wouldn't be that bad

That's why I'm interested in it.. it comes cheap stock so I'll have plenty of money left to mod it to my liking :)

true dat

[Yaris Revenge]

I've never delved much into the realm of forced induction, so I'm ignorant on the subject. A guy at work says the difference between turbo and SC (aside from setup) is that SC tends to be faster off the line, while turbo has more punch at higher speeds. Anyone want to clarify? Oh, and do you use fuel management with SC like you do with turbos? I'm assuming you must, I just haven't heard them mentioned together (turbos seem to be more popular for some reason, so that's all I ever hear about).

I'm dying to get my hands on one of these and play around with it!

[why?]

Turbo's are more popular because they are used to get max horsepower and they can get bigger numbers.

Superchargers are usually pulley driven, while turbo's are exhaust driven.

There have been many discussions as to which is better, but in general if you want max hp go with a turbo, if you want max acceleration go with a supercharger.

[el yaris]

Well I am one of the guys from the el prototypes shop. I drive a supercharged matrix and a turbo tercel. The 1nz motor is not good with handeling boost. The engine will last maybe 3 months or 9 months at 6psi depending on driving it is pretty much a time bomb. The rods are no bigger than a pencil in thickness. We plans for a yaris as soon as they come out. We will probley make a header and intake. There may be other stuff for the hard core to come.

There's a supercharge kit for the Scion xB from GReddy. They have the same engine and I've heard of people getting them for the xA already. Not sure if that's just a rumor, but....... :biggrin: :drool:

"Chosen vehicles with limited space for modification and vehicles with close-coupled catalytic converters are idea for GReddy supercharging. State-of-the-art Magna-Chargers with internal by-pass minimize drag while fuel tuning is optimized for smooth linear power, with our pre-programmed e-manage and hi-flow cast intake manifolds. Included GReddy belt and pulley systems make this a complete bolt-on upgrade."

Superchargers tend to see less gains in hp... They are belt driven, mostly by the crankshaft. This means that they use part of the engines power just to make them function... Sometimes it takes 60 horsepower (or more) to drive the SC. The plus side is the airflow helps it create more power than what is losts in the first place... But SC's do tend to make less power than Turbo's.

Turbo's use exhausts gases to drive them, which would otherwise be wasted by NA cars and Supercharged cars. Since it uses exhausts that do not benefit the engine, it sees no horsepower losses as the belt driven SC does.

Since the turbo has no gears, it tends to run more quietly. Turbochargers are also smaller and wieght less than SC's. Therefore, I'd go the turbo way...:wink:

[evolutionist03]

One question! The supercharger is more mechanical driven right? If you are concern with reliability, would you get a supercharger, or get a turbo?

[why?]

If you are concerned with reliability get neither.

If you must get one though, just make sure you get someone who knows what they are doing and spend a lot of time on the fuel curves so they are right.

The majority of aftermarket pressurization fails because the tuners did not spend enough time adjusting the fuel maps. Oh, getting a new ecu etc is also the way to go.

:stupid:. Don't need a new ECU but a piggyback should do the trick.

[why?]

:stupid:. Don't need a new ECU but a piggyback should do the trick.

A new ECU would be safer. Better off to tune it to your specs then have a piggyback that kinda sorta maybe does what it should.

Especially if you're looking for reliability and future tuning growth.

Piggybacks are just stop gap measures.

[w1ngzer0]

Huh? kinda sorta do what it should? I've never herd any problems with piggybacks comming from the nissan and subaru community. There is the e-con and the AFC from apex.

Thats why when you get the piggyback you program it :)

[why?]

lol. To each their own. I'm just shocked at the cars I see that run 4 or 5 or more piggyback computers. It just seems silly to me.

[TRD_Yaris]

yeah, turbochargers are more efficient. They run off of WASTED exhaust gas, which can be UP TO 70% of the POWER released from exploding an Air/Fuel mixture. And, if you get a SMALL, BALLBEARING turbo like a Garrett GT25R or GT28RS and you would have VERY minimal lag anyway.

Superchargers are pretty cool, but aren't efficient past 5+ psi. It really just depends on your situation. I think everyone would love to see some supercharged and turbocharged Yarii in the near future.

[mikeukrainetz]

I love superchargers, but im from the old school musclecar crowd where your NA engine is already pushing 350 - 400hp. Nothing beats the whine of a big block supercharger. They are much simpler as well, much simpler to setup and run a hell of a lot cooler - no turbo timers neccessary.

I think turbos are used mostly on low displacement imports and domestics to make the most of the power they can make, like its been said SC are parasitic, some more so than others. Turbos are more efficient to a certain degree.
When the Yaris only makes 100hp you dont really want to pull 20% of that to run a SC to make back only 10% (130-140 safe hp) - you would need a higher psi SC to make the same power with a turbo at lower psi

[wlfpck]

exactly... since the s/c run off the pulley, it's essentially using/sapping the energy from the car to create more.

there for you see more import cars which generally have smaller displacements using turbos to make up for the lack of displacement.


also, turbos can be boosted up to a very high pressure. I think best example is Cheesefrog's civic which using the stock D series engine managed to kill a viper.

[mikeukrainetz]

lol, sweet.
Love to see the mid-life chrisis guys face after that one...

[wlfpck]

yeah. seriously. that civic is just plain sick... From what i've heard that was a mopar viper too. not sure bout that part. The video is amazing though.

[wlfpck]

well... for those looking for some cheap quick power... i found this.

www.electricsupercharger.com

from the videos and the concept idea.... it seems like this does work.. not sure though. it might just be a scam but idk.

[heylookitsjames]

lol... that's pretty lame. You could build one at home depot for way less than they are charging.

[wlfpck]

i don't think so. That motor for that fan is pretty compact. As for getting the parts at home depot, nice try. No you can't. Your mighty attempt at a witty remark has failed miserably. Congratulations. You are now promoted to e-thug.

I talked with the people at grd performance. They said that this would actually work but with the connection directly after the filter, you wouldn't even see 1 psi.

[yariman]

Those things are crap!, don't waste your money.
