Bang for your bucks – DC5R mods

[2002 TeGgY]

CAI is impossible? I think not!

You will be able to get an Injen CAI for the DC5s for roughly $450 - $550 depending where and the installation is easy to do it yourself from what I've heard.

Places to source them include the clubrsx store at www.clubrsx.com or tozka.com. Toda AU will be able to source them for you also.

There are other brand including K&N Typhoon that you can source from one of our traders, "egSi" so shoot him a PM re this.

thanx a lot for that, the only thing is that the web site u gave me is from america i was wondering if any one knows of a place in sydney that sells the Injen CAI. thnx

i was interested about the Lightweight flywheel & Heavy-duty clutch. will that cause increase HP of dc5r? and how much it cost??

Bang for your bucks – DC5R mods

By request,
Bang for your buck – DC5R
As with DC2, The DC5 is pretty fussy when it comes to mods that actually work…
On the race track… The following parts are must haves…
Oil cooler / low temp thermo fan switch…
If you can’t afford a good aftermarket radiator, at least fit a low temp thermostat.
Both are better…. Suspension & brakes also need to be addressed.
These aught to be addressed before you chase any extra HP.
As for getting more power, Honda’s are pretty fussy…
The actual parts combination is everything…
It must be put together exactly right… I can’t stress enough how important this is.
Once it’s put together right, it can be tuned… This also should be spot on…
The three work together, if 1 side has a weakness, power suffers…
Examples: Your pipe dream combination isn’t right… Power suffers…
Your mechanic doesn’t really know what he’s doing… Power suffers…
Even with perfect combination & assembly, with crap tuning… Power suffers...
NB: When fitting a heavy duty clutch to a DC5R, the front and rear engine mounts should be attended to.
That is fill them with sikaflex or use Mugen inserts / mounts.
This will avoid the inevitable knocking on the floor under the driver of the exhaust system.

#5 – Header + S2000 cat + cat-back system
NB: DC5R cat back can be used on base model with small mod to rear or base model cat.
Further modifying the airbox – Hondata style also adds a little power…
For those who aren't sure, automatic models do not have flywheels or clutches

Regarding modifying your car.
If you can’t afford to do it the right way, avoid the temptation to do something right now & save up until you can afford to get the right parts.
Obviously I recommend using only TODA products where they exist for the application.
Products from other manufacturers can be substituted with varying levels of effectiveness.

Ok… as before… Comment away...

yeah nice... How much is a minimum budget, and how much is high?

[TODA AU]

Min budget approx cost:
#1 – Intake - From $450 for local intake to approx $1600 for GruppeM + fitting.
#2 – Full exhaust without any compromises will set you back $3750 fitted, drive away. Ie: Toda header, Spiral cat, Toda cat back & swaybar, incl fitting & welding. Purchasing only the cat back system will firther reduce costs (and performance) as the header, cat & swaybar are ommitted.
Using lesser parts will reduce costs & output.

High budget – To include all top shelf parts & workmanship, you'd need to budget $25K drive away.

[FEELDV]

"#2 – Full exhaust without any compromises will set you back $3750 fitted, drive away. Ie: Toda header, Spiral cat, Toda cat back & swaybar, incl fitting & welding."

I don't know uz manage, These prices are so large that i don't know who would spend that much for just an exhaust, for almost $4000 you would expect a Turbo Conversion lol.

[FunkyR]

that's a header, cat, sway bar AND exhaust though...

[TODA AU]

I don't know uz manage, These prices are so large that i don't know who would spend that much for just an exhaust, for almost $4000 you would expect a Turbo Conversion lol.

We manage just fine thankyou.
I would have to say you are also correct, there is probably a lot you don't know...

[dark138]

i think the point here is with parts, the performance and price graph isn't exactly linear... to double the performance of the same part, it often takes more than double or even quadtriple to price to get the absolute best.

now this is where i find its contridictory, to pay that extra "sum" to modify a car to get the desired performance, you may easily find a stock car with which is already capable of doing such already but cheaper?

this is where i m standing and dunno whether i should be spending cash to those extra few kws

[vupham]

I guess if you like that particular car, you would modify it because after all it is a hobby at the end of the day. If you dont have $5000 lying around to do that min budget, do it bit by bit, thats what i am planning to do save save save

oh toda, i emailed you about the price for the fly wheel and clutch, still havent got an reply from u yet

[SiR CRX]

Regarding the Toda exhaust system, is it not suitable for the street because it is too loud? How loud is it actually? Am I right in assuming that the Spoon and Mugen exhaust systems don't include a catalyst?

Cheers

[vupham]

I was watching a video clip from one of the member at clubrxs who just installed the toda exhaust system. It sounds quite nice actually, not loud. Atm its my preffer choice exhaust system because u can just bulk it on too i think. $$$$ save save
