Lightweight Flywheel for the Yaris?

[NonStopTuning]

What options are currently out there?

Would anyone be interested in a very high quality lightweight option from NST?
Price would probably be in the neighborhood of $350-$400 and weight reduction would probably be about 35%.

Should we plan to move forward with pursuing something like this?

[cali yaris]

Fidanza makes one for us, I have it in my car. They are about $300. Go for it, Mike, and let me test it. I'll probably drop the trans anyway to put xB gears in soon.

Can you make us a gear set too? :biggrin:

[NonStopTuning]

Hmmm... interesting :smoking:

[mikenacarato]

i wouldnt mind one later. it looks like your products are good so if you end up making one i will more than likely buy it from you.

[whooppee777]

+ Spec makes one

[cali yaris]

they sure do; haven't seen that one before. $300.

Mike: I'll take an NST flywheel any day of the week. Go for it! :headbang:

haha funny im so :smoking: right now lol but MIKE IF U DONT MAKE THIS IM BOYCOTING U GUYS!!!!

j/k j/k

im deff in for the flywheel and/or gears...

what does a lightweight flyweel do anyways?

[ROCKLAND TOYOTA]

why not send whooppie one to test out with his supercharger setup he's installing.....

[d1nzfe]

Can NST do custom work?
Can i send in a pulley that u dun produce and custom make one??

YES! In fact, we build custom pulleys all the time. Please feel free to look for me on AOL Instant Messenger at the screen name "NSTonAIM" or give us a call at 281-917-0221 should you wish to chat about a custom pulley.


For everyone else... please keep the discussion going regarding flywheel options...

It is a matter of rotational mass. Most of what a flywheel does is providing inertia to keep things running in between cylinder firings. With a heavy flywheel, you get smoother operation, because of increased rotational mass carrying more inertia, BUT it takes longer for the engine to run up to speed, and it always has to be doing more work to keep the mass of the flywheel spinning. If you lighten the flywheel, you make it easier for the engine to spin up to speed, but also remove some of the smoothness of operation, especially in cars that are use primarily for street driving. When you let off the power, the engine will drop down in speed faster. This can lead to herky-jerky (a highly technical term :biggrin: ) operation. It is a balancing act when weighting the flywheel, you want it heavy enough to be smooth, but light enough to provide responsive performance.

[Tamago]

does xA/B/Echo work? it should, right?

if so, i heavily recommend Fidanza (not taking away from NST of course)

[CASTREX]

Flywheel for the xA/xB/Echo = Flywheel for the Yaris

Clutch components are also interchangeble

[whooppee777]

DO IT!

[Thirty-Nine]

I've only driven one vehicle with a lightened flywhee--a Ford Focus--and the difference was amazing. The flywheel on the Focus, however, is uber heavy, so the lightweight version was very pronounced. I wonder what it'd be like on the Yaris?

[Tamago]

Flywheel for the xA/xB/Echo = Flywheel for the Yaris

Clutch components are also interchangeble

then i would 110% recommend my setup:

Fidanza flywheel
Spec Stage 3 clutch. overkill for most situations, yes.. heavier than a stage 1 but lighter than a stock clutch. 100% streetable. not a on/off switch yet it's held 12psi of boost (guessing 180whp +)

This thread is for interest in a NST flywheel. So if your championing another flywheel or adding your .02 cents stop. People are in this thread because they would be interested in a flywheel from NST not Fidanza. BTW I would love a NST flywheel.

thanks for the info. so this thing will give better gas mileage and performance? :smile:

yes. it should less engine work

[RagnaCaT]

Question! Is it true that it's harder pull out of 1st gear in a hill well I've heard you tend to loose starting power and have to rev higher to put the car in march. Got to now cuase I leave in a hill and everything around is mountains.

[at3GG]

If I remember correctly, cali once said that the tranny has to be disassembled for this. If so around how much do you guys think it would be to have this installed at a shop? If it was reasonable I would get an NST fW before any of the other simply because of the effort they have put into this community. Whether you bring this out or not, NST, thanks for everything else so far. Keep it coming!

[NonStopTuning]

Thank you for all the kind words and the replies everyone, I certainly do appreciate it.

Just to give you a little info...

I have had a few discussions with the good people at SPEC. We have used their products in the past in some of our NST drift cars, and they have held up very well. I also know of other FD, Pro-AM, and NOPI series drivers who have used their products with good results. Their service has always been great, and their products are built here in the USA (something very important to us.) These are the main reason I decided to contact them when we started discussion about adding clutches/flywheels to our lineup here at NST.

According to the info I received, SPEC has done the R&D on a Yaris FLYWHEEL on a few cars, but has yet to sell any to the public. While they do list an item number on their website, and an MSRP of $319, they have no product actually on hand for sale at this time.

Here is what I would suggest... I can go to SPEC and order a large number of Yaris Flywheels, and we can hold an NST GB for said flywheels at a nice discount. I know a few of you have already expressed interest, I hope you're still interested. With enough interest, I think we can do this at a price of under $300 per flywheel.

Any takers for this idea?

[mikenacarato]

yes in a month or so

[1NZYaris1]

Just curious what sort of weight differrance are we talking about, does
anyone know,:iono:, any chance that spec has put this to a dyno test.

[Jerkratt]

moneys tight but u know i would be down

[pinoypizzaboy]

is it true that lightweigt flywheel is bad for a turbo setup? I think Ive read it somewhere here.

[mikenacarato]

my friend has a turbo car with a lightweight flywheel...no issues.

you wont see any HP difference on a dyno....but it allows the engine to hit redline sooner in real life....

here's a dyno of my XRS vs another guys xrs w/ the same mods....he puts down more HP than i did, but you can see the graph is vs time and i have a fidanza flywheels (was 6.5lbs vs 13lb stock, iirc)

[cali yaris]

both my turbo cars have lightweight flywheel, including the Yaris - love it.

[tk-421]

I'm definitely interested. Keep us in the loop, Mike!

[NonStopTuning]

We would be talking about roughly 30% weight reduction compared to the OEM Toyota unit.

There are no dynos, but the concept is very similar to our lightweight pulley kits. And A LOT of you on these forums are very familiar with NST Pulleys. Weight reduction in the rotating assembly leads to better power and torque transfer to the wheels, better acceleration, better throttle response, and even better fuel economy.

:burnrubber:

Thank you Garm. Turbocharged cars do very well when you reduce weight in the rotating assembly.

As I stated before, we have used SPEC units in our drift cars... Turbo S13 240SX and Turbo AE86 Corolla.

If lightweight flywheels were a bad idea you wouldn't see so many companies building them for cars like the EVO, STI, etc.

:thumbsup:

[NonStopTuning]

Anyone else? :iono:

C'mon people! You sure can't beat the price...

Here's a few price comparisons:

C-ONE Flywheel: $409 (http://www.kamispeed.com/product_info.php?cPath=1131_2061_2071&products_id=1575&SesId=b20c506a6fd3c64fa186856cc0f4d0aa)

[cali yaris]

This is one of those "You have to jump ALL the way off the bridge" mods -- hope more Yaris'ers will go for it.

Or converting it to NZ dollars + Freight :cry: ouch otherwise you could count me in ,
Unless you want to send me a free sample for testing purpose's on a 1.3ltr :laugh:
Oh well it was worth the shot :thumbup:

[pinoypizzaboy]

I'm sold! when's the GB?

[staypuft]

damn i asked for nst to make this 2 years ago, glad to see that there is now an interest, count me in, btw are we ever going to get them sweet nst cams?

since NST isn't currently making a flywheel what is the best option right now? why so much of a price difference between these 3? anyone know which one is the best in terms of performance and why?

[dallas]

I changed to a light weight flywheel in several cars. In my last VQ35 Nissan engine, it would rev up much faster and the car felt much faster. It kind of feels the same as a light weight crank pulley only better. It made first gear launches hard without crazy wheel spin, and at the race track. While I could swear it felt much faster, I lost one tenth in the quarter mile. I think it was faster in each gear, but I would loose when I had to shift. If your road racing it is much better for gaining revs comming out of corners etc, but on the drag strip not having the mass of the flywheel will slow you down. Buyers beware!

[TheRealEnth]

I say you wait till every1s tax returns come in =D.. then start the GB

[Tamago]

its the installation that isnt cheap...

you could do it yourself with:

jackstands

a hi-lift hydraulic jack

8mm
10mm
12mm
14mm
a hammer and pry bar

a buddy who can lift 80lbs laying on his back

i've done mine twice, once with help, once without. a little ingenuity will get you a long way on this one, save you some serious coin!

[Mz3oh5]

FORUM iS OLD but I have been thinking about for months about NST Crank Pullys + MI Ultralight Flywheel combo to install at the same time with my DC Headers, other than these two mods that will increase horsepower + throttle response has anyone gone any further?

[tk-421]

Try a throttle controller and a 1ZZ TB. They both increase throttle response perceptively.

[cali yaris]

Well, yes I think I went a little further. :biggrin:

[why?]

crank pulley set, lightweight flywheel and racing clutch, and lightweight wheels. Good setup. An Intake helps too.

what are you looking for? and what type of further are you talking about?

[Golddeenoh]

I went a little further, the question is more about what you want to get out of it.
