had my car dynoed at chasers today. engine wise its stock apart from the 2.25 cat back. im planning on doing a CAI and tuned VAFC II installed in the future .

what do you guys think?

Looks like quite a smooth power curve. Bit over 100hp. Not bad mate. Will be good to see the difference some mods will make to the output though.

How far into the future are you looking at doing the other upgrades mate. It would be good to see some mods and the new curve. Most dyno graphs plotted on here are finished products and you cant where they started from.. 77kw isnt huge but it is a nice smooth curve though so it will be a great place to start.. What figure you aiming for? Keep us up to date with your progress..

i might be wrong, but I believe VAFC won't do any good to the new civic.. as vtec kick when the gas pedal floored.. correct me tho..

i Dont think so, the vtec kicks in on pressure sensor on the throttle. and also its execute on certain rpm. example if you floor it 100% throtle it will not engage vtec at 3000 rpm. if you get what i mean.

are u talking bout the VAFC II? cos the VAFC will not work cos its not compatible with i-vtec while VAFC II will.

:thumbsup: Nice work m8
N15 pulsar's get about the same with the same mods=you've got plenty of potential to work with!

Keep on it!!

No, R18a's vtec can engage at 2000, 2500, 3000, 3500, 4000 or at any RPM above the minimum. Because, it uses vtec to switch between Atkinson cycle and Otto cycle mode. When you floor your accelerator at above the minimum RPM and above minimum load, vtec engages.

thanks mate :) . considering my car is mostly stock (apart from catback) im happy with the results.

CAI will be nice tho.. seems like people in the states gain "gentle" power improvement from installing the CAI.. but what obvious is.. for that 'woot-woot' noise..

Agreed.. Get a cold air intake mate, best thing i did for my crx. Sounds fantastic from 4k up but standard below that so its not annoying. Gave noticeable improvement in mid range too. Well worth the money i think..

about the cold air intake... do u actully get any power from it? apart from the induction noise im not sure if its worth getting. theres a fujita CAI but comes at $500 and claims to produce a 6hp (4.47kw) from it.

dont think this is correct mate, they said that it will gain 11hp (at the wheel they said) using the Short Ram Intake. How come the SRI can gets more power than the CAI?

Because dynos are done with the bonnet open. If you drive with your bonnet closed, SRI is like stock. I used to have that.

I would go with CAI intake, couldnt be happier with mine. You dont want heatsoak hindering performance and CAI sounds great.

As for power gains, i found a review on zc powered crx like my car. They dynoed it at about 95hp then first mod was AEM CAI and they got 98hp peak but got over 5hp gain in mid range, then they did skunk 2 cat back and got it to something in vicinity of 104hp then they did dc header and got nearly 110hp. This car was pretty high k's and i wouldnt be surprised if the kit it was running standard was well past prime but its pretty cool review.

Anyway, i guarantee you wont be disappointed with CAI

based on prev exp.. CAI will be well spent.. if you get it installed with the other things.. such as piggyback, chip, whole exhaust set, ignition, and not to forget.. great mechanic to set-up.. by the end.. all of these will cost you a fortune.. and it's just a matter if you wanna spend that much..
If you decide to go with CAI only.. there might be a slight improvement.. but I can't really feel it tho..

It's worth it only for the sound. Unless you enclose it and add a cold air feed to it like the GruppeM intakes.

OK... before we went too far... i think I should've mention that my car is an Auto :( so... CAI wouldnt be possible to fit in (according to Fujita website, it says "Manual Only") T-T Thats why I'm thinking of SRI...

Yeah, because the transmission case for the auto might get in the way. well, time for you to do SRI and make an enclosure if you want power like I did for my Euro: http://www.ozhonda.com/forum/showthread.php?t=53595

It's because cold air is denser, so it makes a little more power. Hot air is less dense, so you lose power. With an SRI, what you gain in flowing, you lose in the heat.

look carefully. the one SRI ur looking at is for a civic SI. this is the US model's top brand of civic hatches with a K20 in it.

my car has the R18a (SOHC i-vtec) in it so the claim power levels will be lower.

Ok... mine is the Sports model, so it has K20z? So that means I will get around the same? =S

srry but unlikely. the civic SI is more closely linked to the civic type R (with the hardcore K20) then the civic sports

will I expect too much if I want to gain at least half of the figures (4.1kw)?

I would only expect psychological power gains. 4.1kW is too small to be felt on the road.

one last question from me... Is it worthed install this SRI into my 06 Sports Auto?

crx51

15-03-2007, 04:23 PM

Mate its your call, noone elses, its unfortunate that you can't fit the cai in the auto. As has been said you probably wont gain power with sri due to heat soak cancelling gains in flow but it will sound cooler. I myself would try and find a company that does cold air or even custom fabricate something that draws cool air (would be rewarding). Your car though. Hurry up and do some more so we can see the difference on the dyno mate!! I like seeing before and after dyno readouts...

If you don't like the noise, don't do it. :p You will hear it more in an auto than a manual because you usually use more throttle + you have kickdown.

hm... i sure like the sound of CAI but never heard any from SRI... aaronng with the custom box you suggesting, will I get colder air using it?

the k20 you find in the sports actually has more in common with the Integra Luxury and not much to do with type R cylinder heads at all. The sport variant has a lowly 114 kw @ 6200 rpm, which is hardly the 150+ kw from the K20Z.

As for the R18 engine and auto transmission, its a very fuel efficient boat anchor.
