My black dc2r

[vtec_yoo]

Finally after months and months I have purchased my dc2r!!

Nighthawk black with red recaros...

First thing I would like to detail the car get some minor scratches out of the paint work.

[crx91sir]

nice car mate.
Looks good! How many km?
How much for that?

[vtec_yoo]

Thanks mate,

It's just ticking over to 110,000 Kms.

Has full log book history including receipts etc..

I got it for a reasonable price =D.


I'm trying to toss up if I should use it as a daily or keep my current pos daily and just take this out here
And there

[EKVTIR-T]

nice man,they look awesome in black

I would suggest get some jdm dc2r 16" wheel if you keeping it oem look

[vtec_yoo]

Yeh gonna keep the standard look,

Probably do some basic bolt ons in the near future.

It has a mongoose m80 alarm really good alarm except the auto lock after 30 seconds of shutting the doors gives me the shits.

[eLtrix]

^ it closes the door for you?!

[vtec_yoo]

Nah if I shut the door and don't want to lock it, it auto locks

[infurNOS]

Finally, congrats!

[vtec_yoo]

Finally, congrats!

I know!! Thanks mate,

Love the drive feels great!! Just out of curiosity what should I be expecting to get out of a full tank?

Can't wait to get a CAI.. Hear the real Vtec crossover

[infurNOS]

I usually max out at 420 with a fair amount of VTAK

Just remember, the louder the crossover, the more power you are missing out on!

[vtec_yoo]

Really?

I drove a dc2r with CAI exhaust and headers and felt so much quicker!!

[mocchi]

Nah if I shut the door and don't want to lock it, it auto locks

look up manual on the interwebs, it should show how to program it

[Johnie]

Nah if I shut the door and don't want to lock it, it auto locks
My integra does the same thing, when i hit the brakes, the doors lock, so there must be a way to program it

[vtec_yoo]

Just one thing I've noticed guys, I think it's when I start to accelerate.. Not 100% sure if its caused by that

But it kind of makes a clicking noise.. Like just one click....

Anyone know what it could be?

clicking noise from the engine bay ? .. when you disengage the clutch ? need moarrr info .

I get 500 + from my b18c7 ..

cross over will be louder with an injen but if you do decide to get it tuned in the near future, you'll realise having loud crossover isn't everything !

all about that smooth power curve !

[vtec_yoo]

Yeh it's kind of like a ping pong hitting something.

I found whenever I let go of throttle usually in gears 1,2,3.

Can't hear the noise when my window is up. [in b4 keep window close jks]

And is definitely coming from drivers side tyre, around the axel

I've looked through google been led to other forums no one ever figured it out.

Could it be the exhaust rattling or some rust collection in the exhaust.

why do u say that?

[White Noise]

Looks nice mate. I would change the rims and leave it as it looks :D

What are you looking at doing performance wise?

[vtec_yoo]

Thanks mate.

For the mean time just fixing the problem I have stated above.

Then in the future CAI, exhaust, extractors and hondata tune.

[infurNOS]

why do u say that?

Because, for a naturally aspirated VTEC engine, the torque curve should be one long, smooth pull from idle to redline. If it's not, and you're feeling a large jump in the torque curve after VTEC engages, you are losing power in the midrange prior to engagement - usually cause by bolt on mods not tuned to the engine.

My b18c civic was tuned with a 3800rpm VTEC engagement, you could not feel any VTEC surge or switchover noise, just a very nice and smooth power delivery which pulled all the way to 8200 rpm. It was beautiful.

[vtec_yoo]

I thought the noise was just from the air intake letting more air into the engine hence more
Hp and power creating the louder crossover?

[rhys.l]

I can see where inforNOS is coming from, but that statement is strictly not true. A louder crossover can come purely as a result of material changes and therefore produce no change in power delivery. You could replace your stock intake arm with a metal one connected to the airbox, remove some of the resonator piping and you would have a much louder cross over with no change in power band.

A cold air intake will give you a louder cross over because of the materials usually involved (a metal intake pipe and pod filter), and whilst it will also change your power delivery, it's not because it is louder. If you ran the same length pipe except in plastic, you would produce the same power in the same areas with a quieter cross over.

What infurNOS said can easily apply in other areas though.

clicking noise - possible worn driveshafts

clicking noise - possible worn driveshafts

Not sure, I've had a few mechanical minded people have a look at it and they haven't really pin pointed what it is.

I'm taking it to deddy at top one auto on Wednesday for a service and to have a look at the issue.

I've heard very good things about top one auto? Anyone else heard the same?

[madapo]

+1. Compared to a stock dc2r, when you put good breathing components, the response is so much better. Had a spoon muffler all the way to my dc headers. Plus an injen cai. The sound and response was amazing!

[crx91sir]

will you do jdm front cut?
I am looking one for my dc2^^"

[eren]

Very nice , you said you had some minor scratches i recommend ( Wash > Polish > Wax ) scratches on the clear coat should go away.

It's hard to make a general statement that louder crossover = less power, as it sort of does apply but in the case of a CAI it's only gonna be more audible because of the open air filter, metal piping and lack of intake resonator (as rys.I said).

Although the way you explained the torque curve is certainly true. If there is a dip in power and then a huge kick when the secondary cam lobes are engaged, then the engagement point is at the wrong RPM for that engine setup.

If the power line on a dyno graph starts to drop off even a small amount before VTEC then it needs to be set earlier, however if it dips when VTEC engages then it must be set later.

sorry if I'm getting off topic here.. haha :)

very nice ride OP :thumbsup:

[butterfingers]

According to "official" sources the k20 torque curve looks like a shallow lopsided M. With a dip in late mid range around 4500 and rising up again as vtec engages at 6000

Before purchasing my dc2r I drove a few dc5r' and like many others say the power delivery is completely different.

I personally found the b series had alot more of a power kick once Vtec had been engaged, and when changing gears the k series does not stay engaged in Vtec.

Just my personal opinion.

[butterfingers]

B series is much more flat up till vtec therefore much sharper surge of power. its like hitting a curb while the k20 is slightly like a roller coaster

[JDM DC2R]

Before my dc2R was tuned at vtec engagment i got a increase of 15kws instantly. Give the more rush and surge affect. But having a smoother power curve after tune is alot better to drive with and for performance. But it losses the vtec kick affect!

Heres dyno sheet!

If you want to actually hear the vtec crossover, take the top airbox cover off and take it around the block like that... 10 x louder sounds amazing! I've got an ARC Magic intake arm and box in my ITR... the crossover with the stock rubber arm and poddy shits all over the sound of the ARC setup. So much louder and aggressive!

[vtec_yoo]

Update guys. Just got the service performed by deddy at top one. Was happy with the experience, sounds like a genuine mechanic.

The noise I described was just my driveshaft needing tightening.

Had the gearbox oil replaced also makes a big big difference.

Was it the kind of ticking that was more frequent the faster the car went? Did it happen at all speeds?

[vtec_yoo]

It would occur at all speeds however only when in low rpm or taking your foot off the accelerator. It was nothing at all just annoying.

Besides that and my rear brake light he said the car was great.

Always good to hear by a mechanic that knows his cars.

[TGW92]

Similar to JDM DC2R, I was getting around a 10-15kw jump as soon as vtec kicked in, matched with a LOUD crossover....

After a tune crossover is a bit quieter (maybe even a little higher pitched...) and there is no "feeling fast" it actually is fast now :p and keeps building strongly :)

CAI is an awesome mod though, but keep in mind that afterwards you will probably feel like headers and exhaust and tune and........... ;)

[adamdc5]

cool car

Lol yeah I want to do full through exhaust system CAI and s300 hondata..

Not sure what exhaust system to go with though I want something nice and quiet and then opens up with Vtec

Was looking at js racing but heard it takes a while to import

I ended up going with the fujitsubo rm01a... I wanted something similar to you and I am very pleased with it :)

J's racing will be a little bit louder but they're still very nice exhaust systems, and you may get slightly better flow with them....

[JDM DC2R]

j's is very loud. got mine through JDM concept. catback includes silencer.

[vtec_yoo]

yeah but fujitsubo dont make headers do they?

Not sure if its true or just false info but i have read up that having the same brand headers/cat back allows better flow and cancels the need for any custom welding etc..

I would be going with 4-2-1 headers also

Would you consider 4-1 at all ? I had them on my EG with B18c2 and the midrange and top end it gave was awesome!

[vtec_yoo]

Im not really definite on 4-1 although i have heard there recommended more for track as they give more midrange and top end but in some cases you may sacrifice some power down low, where as with 4-2-1 you get better low and midrange..

please correct me if im wrong lol

Not quiet the same engine but my B16A would have a noticable kick when vtec engaged.
But after i did a valve clearence adjustment, the kick wasn't quiet as noticable but overall felt like it was more smoother and had more top end power.

Turned out that a couple of my exhaust valves where way too closed.

You sure? Valve clearance adjustment won't make any noticeable change in performance unless you make the clearance too tight. In which case the valve does not fully close, causing loss of performance.

[butterfingers]

A tune will solve all your problems

I have 4-2-1 on my DC2R now, midrange isnt that impressive. Maybe im just use to it.

[butterfingers]

i believe almost all free flowing exhausts on a small engine like this will sacrifice low end for high end, unless you have a tune.

try shooting water through a narrow straw, and a big easy way straw. first do it applying light pressure, and then again blowing hard (LOL)

the opposites are true at each end of the scale

Ya that what the problem was, the 2 out of the four exhaust valve had no gap between it and the cam.
Feeler gauge couldnt get though at all.
