Toda Flywheel

[TaPiR]

Hi all,
What is the weight for toda flywheel for B series?
and compare than B16B what is different weight?
how the response when changing to this lighten
flywheel? better RPM or HP?

Tq.

Toda is 4.1kg/3.9kg thereabouts, although I've heard they have other versions that are lighter or heavier depending on application.

you get more power by reducing the resistance to rotate the flywheel. Revs fall faster, so you need to compensate when you drop a gear and turn, else it falls out of the powerband.

as for better rpm.. no.. the ECU limits the RPM, not the flywheel, and since it's lighter, revs climbs just a bit faster.

bigger cc... a B20B in a civic with full stock parts is very nice to drive. :P
180whp in a car weighing just a little over a tonne is very nice.

Seriously, more power is cheapest by increasing the capacity of the engine.

Anyway, it depends on what you want. Certain race parts you can put in an engine and still drive it daily and comfortably.

Plonk in racing clutches, full lock LSD and racing fuel pumps, and you'll never drive it comfortably again. Driving becomes a chore, esp if you're stuck at a crawling pace.

Other things that can remove if you really don't bother with them is power steering and air cond. that's considered free horsepower, if you can live without them.

Other types of flywheels sometimes comes in a set with the clutch, like the 'super single clutch' product line from various japanese manufacturers. Personally I like the R's since they're just nice for daily driving, and not too light.

If lightening, get seats, stock seats weighs a lot compared to buckets/reclining sport seats. front hood is a dead weigh as well. Rims and brake discs are a weight you can reduce, but then again, once you see the prices, you'll have to agree that increasing the capacity of the engine is the cheapest way to get more power.

Smoother pickup is a bit difficult depending on your definition, as I've yet to find a tuner for hire that's willing to do part throttle tuning in a professional manner (means they don't use the extrapolate function) There are foreigners that can be hired to do that, but they're prohibitively expensive. As it stands, I'm doing it myself for now which takes days, since I tune the fuel maps a bit at a time spread over a number of days.. not practical for a shop to do, but very fun for an enthusiast to tinker with.

It's not too difficult once you understand the concept, but I wouldn't recommend it for people who don't understand how an engine works.

thank to haltech and shiro for a very good explanation for me....
seriously i still new and only know how to drive the car rather than
known the technologies....
My car use standard stok EK9 engine with plonk into EK body...
so i just wanna know how to optimise this engine.....

if just beginner, do the natural thing.

IHE upgrades.. Intake, Header and Exhaust.

Intake - use those aftermarket intakes from any japanese maker.

Header - smoother flowing, and a lot lighter than the stock cast iron header of the B16B.

Exhaust - less restriction, no cat, more power.

stock b16b is just nice..i think u just need to clean the internal parts especially the head parts..and like what tenshi said..smoothening the inlet and outlet, be it smooth as silk..hehe..and if u're crazy enough just dump vteckiller, some hondata,walbro's, etc..etc..kekeke :)
