Under $2500 Tubo Kit Update 2

[cali yaris]

maybe, but you should drive my car. The T25 turbo spools so fast and early it's amazing to drive -- I don't regret putting in the lightweight flywheel at all.

its not that it wouldn't make it as fun to drive. It basically can slow down how fast your turbo spools thus leaving you less rpms that you are actually making positive pressure. The reason being is because the heavier flywheel puts more load on the engine. More load on the engine = faster spool. Another example is the higher the gear the faster the spool. So if you are in 2nd and starts making boost at 3k rpm it will start even sooner in third because of more load on the engine. Lightened flywheels usually cater more to the n/a crowd.

cali..... I have to agree with you.

My cuz put a Light weight flywheel in his WRX and he said it was the best mod he'd done as in bang for buck.

Whether the rotational inertia puts more load on an engine.... I think the load from accelerating the vehicle would make the load from the flywheel insignificant.

ya i'm not saying it wouldn't be fun and im sure spool isn't a problem with that little guy. I even have a lightweight flywheel in my turbo M3, but i bought that when i was n/a and sold my stock. All i'm saying is if i were going to turbo this car i don't necessarily see the reason in spending money on a lightened flywheel.. thats all.

and in regards to whoguy i'm not sure if thats the mods i would choose if i was going for to imporve overall acceleration, assuming thats what his intentions were, but maybe im crazy? haha It may not seem that insignificant, but other turbo bmw guys have changed back from lightweight flywheel to stock and have seen actual imporvment in getting in boost sooner. The sooner you are in boost the better, but thats just my opinion.

This is why you don't want to get a lightened flywheel especially on a boosted car.

More likley the drivers fault,mechanics and or manufacturer but I agree to an extent.

true, not just for that, but if you have it all apart for a clutch upgrade, it's no more trouble. Throw the LSD in there too...

phxdemon, I'll show you my THREE cars that have lightened flywheels with boost that have never had a problem. I'm not sure what your point is -- is that your car in the pictures? Tell us more about it.

No It just scares me because many time lightened means machined thinner than OEM. More than likely the driver revved his motor to 8k and dumped the clutch which caused that. What manufacturers make lightened flywheels for our car anyway?

[PHXDEMON]

That flywheel also looks like it was made with the same crappy metal they make most chrome rims with

[cali yaris]

^ true!

Fidanza makes a flywheel for us, that's what I have -- and I think Clutchmasters as well.

[saplaymate]

Clutch masters does not, I called them back when I was in the market and they said, "we do not make a flywheel for Xb's, That they where frauds". (IDK?????)

[cali yaris]

what about frauds? chill dude, I said "I THINK" they did.

I know one other company makes a flywheel for us.

[ztrack157]

Fidanza is the shit had one on my blown 383 Stroker 280z. I loved that car but love the fiancee more damn.

[dallas]

I had a lightened flywheel in my 3.5 altima While it felt amazing when accelerating in gear, felt better than the cai and headers together, when I went to the drag strip I was consistantly 1 tenth slower, even though the car felt much faster. I think while power shifting the mass of the lighter flywheel would not propel the car forward. The same way a lighter crank pulley makes the car feel much faster if you run at the track or have a G-tech you may be suprized with the results.

[at3GG]

what is this 0-60 in 3 shifts all about? The top of 2nd is 60 if not 61, as I know Loren...? stated. Even if it wasn't...start in 1st...shift to second....shift to third=2 shifts.
Anyways....dallas, that doesnt really make any sense to me, hopefully someone can elighten us.

[CASTREX]

Top of 2nd gear is 60mph on a standard US spec Yaris Tranny...

If you have a shorter Final Drive or a different tranny then you need to shift to 3rd to reach the 60mph.

That's what the signature is about....

[at3GG]

yeah but 1st to second=1 shift second to third=2nd shift =TWO shifts lol
i guess they're considering putting it in gear before starting off a shift?? if its considered a shift then I concede.

[Sabretooth]

US Transmission shifts to 60 in second gear. I have a coupple vids that I am gonna post up soon of a 0-60 time you can note only 2 shifts.

hitting 60 in 2nd:
