hello readers:honda:

I have a dc2r with only a cold air intake kit. Im planning to get a Mugen cat back twin loop & Apexi power fc with commander. I know its abit costly but what do you guys reakon? Or should i wait & get more engine mods then get the power fc..

I went to Advan [SYD] two days ago and they told me to get a power fc before touchin the engine or it would be just a waste of time touching the engine. :thumbdwn:

But then again the bang for bucks from Advan also say for low buget ( not plannign to get a ecu ) some many mods b4 getting a ecu...

IM LOST.:confused:

The bang of the bucks list are trying to squeeze out everything from your existing stock engine before you make any extra power by the mods, i really think it's a good guide to begin, i will probably follow the list when i start building up my project car

I went through the same when i had my dc2 R in the end for any gain at all i narrowed it down to 2 paths which i never as took as i changed jobs and needed a bigger car, was to either to get the engine stroked to 2.0 then full exhaust mods or vtec controller...

I reckon you should spend money on flywheel, and headers before Power FC. Lightened flywheel makes one hell of an improvement.

A lightweight flywheel aids in acceleration and engine braking...
This is bar none, the best bang for bucks mod to any NA car...
It does this by having less inertia...
As the vehicle must accelerate the mass of the flywheel prior to putting any power to the ground, any mass lost here is benificial.
Ie: 5kg off the flywheel is equivelant to 50kg off the vehicle in actual acceleration once it's passed through the gearbox.
Down side is some lightweight flywheels can cause an erratic idle...
(NB: TODA flywheels do not cause this problem)
Talk of reduced torque is nonsence...

Caution: Machining the OEM flywheel to become ultra light is a very silly thing to do if you value your testicles... These are first in the firing line should it explode.

^---What type one said

After driving my car (stock) and driving another R with lightened flywheel on the weekend, i can say it makes a VERY noticeable difference in lower RPM before VTEC.

Idle problems happen if the flywheel is too light.

16-03-2005, 12:05 PM
i agree with both IRI and Type one it makes a i dont know if its HUGE but it is noticable .. especially down low. only downfall is that i dont think it really causes a problem but when you driving and you push the clutch down with a lightened flywheel the RPMs do drop faster. but that just teaches you to SHIFT FASTER right =P...

Yes. I believe clutch & fly wheel will improve your car by far. But i also believe its a maintenance thing, when that time comes i will defintely get my self clutch & fly.

OR

should i just change it now to have a head start?

The lightest flywheel for B series is about 3.6kg i think? Which is from JUN and heard that you will stall more easier when turn the A/C on

Well toda should be the way to go, or get a redrilled DC2R flywheel with "SPOON" label on it, which is lot cheaper than toda

toda is cheaper than Spoon i'm guessing?.. but is it possible to change the flywheel when u still dont need to do your clutch?.. or not worth doing or...?

16-03-2005, 01:14 PM
Yeah......... just do it all together, if you have extra cash, do final gear as well

Spoon is lot cheaper than toda, about 1/4 less i think, better ask someone who have spoon flywheel, i use Toda :-P

true. i was thinking the same, then why would Advan tell me to get my ecu b4 touching the engine. i also found out that it would cost me another $600 for tuning!:confused:

I am using Spoon flywheel.. i can't really tell the differents

coz i fitted everything at once = ATS4.929 Final drive Excedy clutch and spoon flywheel. to save up labour.

the first thing i notice is the car accerate a lot a lot a lot more quicker than stock, and i also drop speed really quick.

when i first have it on, i didn't get used to it on freeway, i was driving 100, when i release the accerater it suddenly dropped to 80 something. and i thought i am still on 90 something..i just get used to the way i drive b4. i think that caused by the flywheel.

i recommend you should get Final drive 4.929 or ATS 3rd, 4th and 5th close ratio gear, LSD, Clutch and flywheel.

You won't regret.
at lease you won't have tuning problem !

ATSEK4
25-03-2005, 12:09 PM

NO ! he needs DC2R LSD to fit DC2R final drive.
if not he won't be able to put the ring gear/ final gear into that not LSD thing.
coz the DC2R final drive only will fit on Dc2R/EK9 LSD.

I used to bought EK9 LSD for my EK4, i was also going to fit ATS 4.929 final drive. Since that ATS4.929 final drive is for EG6 an EK4, the final drive won't fit on EK9 LSD and i gave up the LSD, so if you have an EK9/DC2R final drive you should get EK9/DC2R LSD to be able to fit.

If you have already get a final drive for your vtir, if you need lsd u need to get vtir lsd.

25-03-2005, 06:25 PM
As i know, All vtir engine gear box are using 4.4 final drive. If they want to go type R final drive, they need to change type R LSD at the same time. Another method, if you buy ATS 4.929 kit, you also can fit it. OR if you want to enjoy LSD and final drive, you need to buy ATS 4.929(for EK9, DC2R) and type R LSD, you will enjoy the handling and more more torque.
ATSEK4 have experience about this situation, if you have any question, i think he can give you the right ans.

Not 100% sure about everything, so don't wanna mislead you, but b18 ring gear and shaft is bigger than b16, but if you try to use b16 lsd onto b18 gearbox, you may swap the b16 gear and shaft to the b18

Correct me if i am wrong

tanghy
26-03-2005, 12:27 PM
the b18 lsd & the final drive (physical size) is bigger than b16a
so b16 lsd & final drive and shaft wont' fit in b18 and vice versa

edw-R
26-03-2005, 05:17 PM
What do you mean?? B16A don't have LSD. B16B and B18C7 are using the same LSD. Andthen, the final drive of B18C5 and B16B are the same. I don't know what "size" you mean.

tanghy
26-03-2005, 05:25 PM
size as in physical size ie diameter, not 4.4 or 4.9 (no of teeth)
b16a have lsd from aftermarket co like kazz/cusco/ etc
b18c5 and b16b share 4.4
audm b18c7 have 4.785

ATSEK4
27-03-2005, 12:07 PM
yeah not the size of the teeth, its the size of the final drive to fit on to the lsd. my ek4 final drive is too small to fit on dc2r or ek9 lsd.

what final dirve are u getting?

of course it is a everyday car, Constantly change gear?? A fast car always revs really quick, so you dun wanna have a quick car? y are you getting clutch and flywheel for?

the rev goes a little bit faster, a lot more torque increased. I found no regret fitting the final drive. I dun have any hassels on changing gear a lot. You can find out in someother usa fourm. everyone is happy with the ATS final drive.

The final drive is designed for everyday car , coz it makes a lot more torque. and also getting out of corner.

I can still go up to 170km with my 4th gear. i never try 5th.. coz i dun need to drive that quick.

According to Honda, as i installed it at honda, and the foreman told me i have gain a lot of torque. hmm.. should i say gain a lot more feeling?

hmm... my feeling is e.g at 5000rpm i feel say 10 "something" when i have my 4.4 final drive, now i feel the same 10 "something" at 4000rpm and 5000rpm have "something" from 5500 or 6000 when i got 4.4. . So it is very good for street i reckon. correct me if i am wrong.. just the feeling tho not theory.

It makes the rpm goes up faster, which means you can "reach" the torque faster, you car still got the same torque....... for example, the max torque appear in 5000pm, then if you have change the FD, you reach 5000rpm lot faster that's it.......

Accel. increase from changes in gearing and lightening of drivetrain components does not = increase in torque.

Ummm.......... I dont really think changing gears constantly is a everyday car. Its like playing Gran Turismo, buy a car and playing around and guessing the gear ratios and the car revs like crazy and constantly changing gears when its only doing 50kms. I hope your car isnt like that.

I think when you change your lower final drive, you kill your petrol faster due to higher revs OR constantly changing gears to eat less petrol and going at lighting turtle speed.

oh man... y are you keep thinking changing gears a lot, dun expect too much .. the rev is not that quick. approx my 1st gear rev up to 50, 2nd 90, 3rd 130, 4th 170km/hr dun know 5th.

petrol is no big deal, its only 500rpm higher than your normal 4.4 final drive.
i can still run 450kms per tank. so i am happy with it.

Seriously, our cars are not even 2 liter. if petrol is a big deal for u. dun waste time on this and spend more time on an Echo. This mean you can never have a very quick car, and fuel economy.

You better off, install everything at once. coz to install the final drive need to take off clutch and flywheel anyway. Safe up labour mate.
