What actually has been detuned??? DC5R

[kanasu]

Hey guys,

I'm picking up my DC5R on Monday... I wanted to know if anyone knew exactly what has been detuned and wether we can get the missing kW back???

regards,
kanasu

Well I believe its to do with Petrol since we cant get the nice high octane that japan gets. Thats just one thing. Others, keep em rolling in guys.

JDM k20A engine has 11.5 compression ratio, whereas ours has 11.0.

Apparently the cams are slightly different as well...thats why JDM redline starts at 8,500rpm.

And probably ECU, ignition timing etc is tuned different due to 100 RON fuel.

[kanasu]

In oreder to get these factors back what settings do we need to change inorder for this to happen. Is it possible or is it just a waste of time and money???

In order to find out exactly what has been done is there a site where I can go to, to find out all this information....

[shebangs]

I/H/E + chip and tune it to 98 RON. Bye bye JDMDC5R.

There are so many aspects of the AUDM dc5r that've been changed from the JDM variant, that you can't justify spending money just reverting it back to "JDM". By the time you spend all this money converting it to JDM, you might as well have modded it to blow the JDM version away. ;)

Accept the AUDM version for what it is, and use it as your base for upgrading your car.

Some differences that the JDM variant gets off the top of my head:
HID option
Fold in mirrors
17" Rims
Different exhaust manifold
Different cams
Variable valve inside exhaust muffler
Different control arms
Brembos

whats a 'Variable valve inside exhaust muffler' do?

[nastyazn694u]

mate jsut get a new ecu liek a hondata and mod it beyond the jdm. no point in trying to make it the same. beat it :)

[VTECfreak]

Do you think it would make much difference in power if we put the JDM cams in? Just to rev that extra 500rpm that the JDM revs to.

[Malenic1981]

I think you it would be better to get cams from one of the performace specialist (TODA, JUN, SPOON ect)

[kanasu]

So what are the recommended mods in order that needs to be done before gettin the ECU put in and the dyno tune done???

Hey kanasu, in my opnion to recreate a JDM-DC5R here is unrealistic. You'd rather spend the money into other mods, e.g. (exhaust, coilovers, ECU, headers or even supercharge) and perhaps some custom body-work etc. When i got DC5R a few months back and really wanted it to be a JDM one. Yet after calculating "bang for bucks" customising to your own liking is better.

RE: From your latest post, I've heard of many different mods people do to the DC5R before ECU (e.g. exhaust + headers mainly + cams. + extractors). Btw. what ECU you after? (people usually go for power FC A'PEXi) If your into performance tuning that much BEL Performance does awesome jobs on R's here in NSW. The www.belperformance.com.au site should have some contact info. and call in and ask. Btw. I'm a big fan of coilovers, and on corners I've out-done AWD cars (e.g. wrx).

The current Power FCs do not support i-VTEC

And in my opinion the JDM and AUDM is tottally different cars.

No, it is not worth gettingthe JDM cams.

I know someone who ported bits of their engine (exhaust ports and etc), mugen n1 ecu (which is designed for the jdm cams in mind) and obviously the jdm cams themselfs and didn't really gain that much.

Like the other person said, cams from tuning comings would be better.

[AMS-89Q]

Are you sure TeMp? Because I remember seeing on a cruise many civics with it and to prove it i saw a blue DC5R with it. I asked the guy "is that a power FC?" re: "yeah that is mate..."
I must ask into it further? I'm 90% sure you can get it. I'd be good if you could source this thanks =)

Turbo it and be done with it, you will blow everything away in terms of modding your car N/A style. But like anything it depends on how much $$$'s you want to spend on your mods and what sort of driving you are doing? A good start that wont cost the earth is headers, cat & exhaust, air intake then you get into ECU/piggy back James at Hondata can help you out 0417 875 785 and that way you maintain all your coldstart and airbags etc. Then get into more aggressive cams, adj cam gears, springs and retainers so you can rev it off its ****, and finally get into suspension so you can get all your extra ponies on the ground better. But if your going to open up your bottom end spend the extra money and go turbo i made 226fwkw and with my next tune i will get more out of my DC2R

The engine changes are:

CR 11.5:1
Redlines at 8400
100 RON fuel
Slightly bigger intake manifold
Different CAT and variable pressure exhaust
Variable Camshaft timing only intake (or was it exhaust) side only where as the JDM is on both
Different extractors


Cheaper to get an ECU tune with I/E +/- header (and it'll give more power).
