    Kor,I live in Eagle and teach at the mtn. I go to Paddys alot.
    Now my Type S calls for 91 where do you get 92 in Eagle -Vail? You ought to try a car thats not naturally aspirated.Maybe a WRX,I like my Accura better,but the low end torque leaves alot to be desired.
    I can't believe your manual calls for 92 as I never saw anything but, 87, 89, 91,93 0r Sunoco 260 can fly a plane on that stuff. The altitude doesn't help at all.

    Cool. Thanks for putting that up. 180 RWHP and 134 RWTQ, either the driver train has minimal losses, or Honda under rates the motor. That's just a little more than a 10% loss.

    The writers seem pretty critical of the throttle mapping. In the real world, it hasn't been an issue for me. But, the DBW is something tuners will soon take care of. I imagine some company will come up with a good program to flash the PCM and give it a more aggressive tune. Possibly even lower the point where the more aggressive cam lobes kick-in too.

    In the late model Mustang world, it only took a few months for tuners to take control of the DBW on the '05's. '05 owners had the same complaints. From what I read, re-mapping the throttle on those cars made a big difference.

    I'm at 15% oil life, so time for the first oil change, tire rotation. So, how hard was it to get at the ol filter on the SI's? Looking in the manual, it looks like it's on the driver side, up above the rack.
    I get the first oil change free at the dealership I bought it at. I might take it in there, but that will probably be the last time I take it in for an oil change.

    The lack of O2 at altitude reduces the need for high octane fuel. After all, octane is essentially a measurement of resistance to detonation and if your environment naturally inhibits combustion....
  • eldainoeldaino Member Posts: 1,618
    from what i have read, tuners have been having a real problem with the si's dbw. each new release gets better, but its not totally solved.

    honda doesn't overrate the motor, the drive train simply has minimal loss.

    Actually, Hondata has already made a ECU reflash for the 06+ Civic Si's but although their reflash extends the rev limiter to 8600, remaps the air/fuel, and engages the 3rd lobe @ 4600 revs..... it still doesnt change the DBW rev hang issue. Hondata has only stated that they've included the Honda official ECU update into their own reflash but do not improve on it.

    go to www.hondata.com for more info.
  • eldainoeldaino Member Posts: 1,618
    what kind of hp/tq increases are you looking at w/the hondata chip?

    anyone check out the ms3 and gti numbers? looks like the ms3 is powerful because its a turbo and its a big engine; not nearly as advanced as the si's or gti's.

    the gti suffered minimal losses of power as well. almost 50lbs of torque over the si in ANY rpm range! and that power curve, can you say ecu upgrade?
  • blairspeedblairspeed Member Posts: 11
    With Hondata, your looking at roughly 10hp through out the rev range (8600).

    Also, with the ms3...its power range is very small. I dont remember which magazine I was reading but they showed the dyno for the ms3 and all the power was from 2300-5500 was the power and before and after it was loosing power. Bottom end suffered from turbo lag and top end could'nt handle any revs past 6k.

    hey all, disaster has struck, in the form of a small stone... tonight i was out and someone in front of me kicked up a loose stone, and it took my windshield... Not a large nick, maybe 2mm, but i've seen stuff like that take out an entire windshield here during the colorado winters... Is there something that i can use to just fix this one little nick to keep it from becoming a big problem later?
  • eldainoeldaino Member Posts: 1,618
    thanks man, i went to the site, and saw some numbers, but thanks for the response.

    the link in this thread compares all three dyno sheet (gti,si,ms3) and MAN does the mazdaspeed 3 have a horrible powerband. it was interesting how they pointed out that it probably required the least amount of engineering out of all the engines; its a big, psi'd-out-the-butt turbo mated to a fairly large engine; ofcourse it makes some power!

    I think that the sis engine is fantastic, but tuning it the same with a bit more displacement would be phenomenal. And vw needs to loosen up on the gti; that power curve has been totally castrated and needs to be released!
  • cz75cz75 Member Posts: 210
    Novus, Safelite, etc. repair windshields and your insurance often pays for it w/ little or no deductible. However, it can't be in your line of vision, usually. Takes about 30 minutes to 1 hour and can be done on-site at work or home. It isn't perfect, but it will be around 95% better.

    I am 38 1/2, and I got my 2007 Civic SI Sedan (Lease) about 5 weeks ago, and I love it (a friend of mine called it a "kid's car"). I kind of got it unplanned. At the end of my 2004 Maxima SE lease, 6-speed (and several months from my wife's 2005 Altima lease end), we went to the first Honda dealer (not the one I got it from), to get information on a 2007 Accord 6-speed (and Accord automatic for my wife). BTW: I was also looking at the 2007 Altima SE which was what I almost got (again, a 6-speed, a requirement).

    Anyway, the sales person had me "try" a red SI (the only one on the lot, and he stated I had to pay MSRP because it was "HOT" - NOT). For about a week (while winding down my Maxima lease end) I was on the fence between the Civic SI & Altima SE (didn't drive the Altima but figured it would be like the Maxima I had).

    I think the selling point for the Civic SI was the sound of the engine. My decision was helped by a 25 year old coworker who has a 2006 Civic SI Coupe. He said, "Dude, you definitely want the Civic SI", so here I am (we both have the Galaxy Gray). My wife also wanted me to have this after test driving it. She would have considered it, but was surprised it didn't come in automatic.

    I am trying to feel whether the SI is similar to performance to the Maxima. I think it is, but it is different. I am looking foward to a new lease (in 34 months) because I have read something about a 2.3 liter, 240 HP Civic SI. That is why leasing is nice because a new car is waiting.
  • blairspeedblairspeed Member Posts: 11
    Very interesting. Where did you hear this info about a 2.3L Civic Si??? Inquiring minds want to know. Myself, im financed for a 60mo.... ;)
  • themistoclesthemistocles Member Posts: 95
    Hey about that rev hang issue, I was reading that you can take it to the dealership and theres a update for the ecu they will do for free to fix it. Im taking in my Si tomorrow, ill let you know how it goes.

    and about your chip on your windshield, you should take it to a place like jiffy lube. When i had a quarter inch crack on my jetta windshield, they drill it out and put this little clear plug thing that stops the crack from spreading. since yours is so small, you wouldnt even really see it. Also they will do it for free.
  • eldainoeldaino Member Posts: 1,618
    mostly baseless actually; look at the hp to displacement ratio on an s2k; there is no way that honda will put such an engineered engine into a civic si here in the states, without making us pay much more than we do now for it.

    the enigine that this 'wish' is about is the k23 (k series 2.3 litre) turbo that resides in the acura rdx. its one of the few honda factory turbos and had lots of tuners wondering if it could be stuffed under a civics hood. I'd expect a jump in displacement before a turbo'd factory civic though. even in europe, the land of all things forced induction, honda opted for another n/a engine in their type r.

    Currently the most powerful civic engine is the k20 in the japanese, (not euro) type r. its the same size as our si's engine, but tuned to 156 lbs ft of torque and a whoopoing 222 hp. But its not cheap, and its murder on your butt becasue of the way the chassis is tuned.(laps faster than an stock s2000.)
  • eldainoeldaino Member Posts: 1,618
    congrats on your purchase man!

    don't worry, after driving the car, your wife will realize how poorly an auto transmission would be on a car with an engine of this nature.
  • blitzebillblitzebill Member Posts: 25
    just did my first all in-city, no highway 1/2 tank of premium ( i never let it go below 1/2, costs too much).... went 208 miles and used 27.75 miles per gallon...

    not bad
  • blitzebillblitzebill Member Posts: 25
    where did you read about that rev hang fix?
  • themistoclesthemistocles Member Posts: 95
    hey i just got my oil changed with 5w 30 mobile 1 full synthetic, and now when i shift from like 1st to 2nd or 2nd to 3rd, sometimes it feels like theres a delay from the peddle to the power. i also noticed the last oil change they put 5w 20 in it! i only had that oil in for 2500 miles because i noticed that. so the delay, could that be cause from the previous oil or is maybe since its 85-95 degrees outside?

    Also i found out, that the dealerships around here have a mistake in there service technician book. its the book honda issues to the dealerships to show which cars need which oil and filters n what not. But the manager showed me several books and they all showed that the Si need 5w 20.. When the Si manual says it need 5w 30 and so does the oil cap on the engine. i blamed the problem on the dealership, now i see that it was hondas fault.. Although im very suprised the dealership hadnt figured it out yet!
  • themistoclesthemistocles Member Posts: 95
    I cant find it, but somewhere in one of the forums on this site, someone said they got ECU update from there honda dealership for free. When i went to the one by my house, they didnt have any update for me, but there looking into it now.
  • themistoclesthemistocles Member Posts: 95
    nevermind, dont have problem anymore
  • civiclove1civiclove1 Member Posts: 5
    Hello. The rev hang issue, can you describe what you're experiencing. Are you experiencing like a hesitation on acceleration through gears? Especially when the engine is cold? I'm just curious. Thank you....
  • themistoclesthemistocles Member Posts: 95
    actually i really only noticed it when i first bought the car. I dont seem to have the problem anymore
  • themistoclesthemistocles Member Posts: 95
    Cool. Thanks for putting that up. 180 RWHP and 134 RWTQ, either the driver train has minimal losses, or Honda under rates the motor. That's just a little more than a 10% loss.

    That is showing WHEEL power, 197hp is to the crank. every car is like that. All cars show there power to the crank, not how much power your actually putting to the wheel.
    and by the way 180 wheel horse power is excellent, broke the engine in very well, ive seen others with 176-178 wheel horse power. yet to dyno mine. how much does it cost for a dyno run?
  • themistoclesthemistocles Member Posts: 95
    im up to 7500 miles, the exhaust tone has changed from that sexy purr, to a throaty even sexier purr. its got the same smoothness to the sound, its just deeper. excellent touch
  • aaronr121aaronr121 Member Posts: 91
    Yeah. I know. I did say RWHP (Rear Wheel Horse Power). I know were dealing with FWD. But I'm used to reading about chassis dynos and RWD.

    And I was impressed by those figures, typicall you expect to see a 15-25% loss of power through the drive train.

    Dynos usually run about $100 for a session. But unless you suspect a problem or are performing mods, what's the point? We have baseline numbers.

    Of course, the dyno operator can always skew a few variables and give you better numbers than the next guy. If you just want some bragging rights.

    I was just checking out my owner link page and clicked over to the Honda E-store. Seems like a lot more has been added since the last time I browsed.

    They practicaly have the whole parts catalog online! It's pretty cool. Decent part graphics and prices. Pretty cool resource.

    Something I haven't found prices for are typical sensors such as MAss Air meters and O2 sensors. Hopefully they'll add those later. Maybe they'll even put up OBD2 codes. That would be great.
  • blitzebillblitzebill Member Posts: 25
    ...DeKalb, IL: James, thanks for the evaluation on the Altima Hybrid. Will be interesting to see when/if they roll it out to the rest of us in the hinterlands. Your thoughts on an earlier comment regarding the premium fuel requirement that Acura places on the TL. I suspect their knock-sensor will allow the engine to perform perfectly well on 87 / 89 octane, similar to Toyota's 3.5L V6 in the ES, but would like your take on it. A little loss of performance at 6000 rpm wouldn't affect 95% of most buyers.
    James Healey: Almost no modern engines require premium. Even those in which premium is recommended can safely burn regular most of the time. Knock sensors in modern engines adjust the timing to compensate for fuel's octane and prevent ruinous knock (pistons shaking in the cylinders). Some will deliver a few more hp using it, but as you point out, mainly at high revs where few people drive. I'm of two minds. If I bought a premium car, I'd think I should be willing to use the recommended fuel for best performance. Part of the deal. I'd feel a little silly using lower-octane fuel. But I also think it's basically dumb to design an engine to run best on premium, and would be very tempted to protest by simply burning regular. Premium, by the way, usually is a marketing ploy, not an engineering decision. An engine designed for premium (that is, the engine has a high compression ratio) can eke out a few more ponies that the same engine not so-designed. That lets the automaker advertise a little better hp, whether that's useful or noticeable.
  • aaronr121aaronr121 Member Posts: 91
    I disagree. From my Owner Link page I can access a much different, Honda operated(not dealer run) site. The site you sent me actually has a lot of parts as well, not as extensive as the Honda e-store, but not bad at all.

    Maybe just me, but being able to access part price right from the dealer, without going there or making a phone call, is great. And getting the blow-out illustrations for parts, even better.

    I wish it was that easy for my other cars. Autozone and Advance have great sites for searching for parts too. But, they show nothing available for Civics 06-07, yet.
  • blitzebillblitzebill Member Posts: 25
    saw one on the Honda site under the Certified Used area for Ohio, in fact, the only one in Ohio for 250 miles around me (east of Columbus). Owner had it for 6 months and put 18K on it (wow).

    Voss Honda in Tipp City, OH is trying to sell it for $21K. That baby's been "rode hard and put away wet," I suspect.

    But its rarity as a Cert. Used in such a large geographic area, only attests to the popularity and demand for Si sedans.

    tfm1973... I read your post regarding your purchase price on your civici si sedan. That was a great deal. What was the name of the dealer in MD that bought the car from?
    I'm in MD also looking to buy a civic si sedan.
    Thanks
  • barrettheadbarretthead Member Posts: 28
    does anyone know if a roof rack can be attached to a new si sedan with moonroof visor? i need it to carry surfboards.
  • tfm1973tfm1973 Member Posts: 14
    not sure if we're allowed to post dealer names on this forum or not. i haven't read the rules sticky. but as long as it's not censored - i went to sport honda in burtonsville. about 30 minute drive for me but well worth it. if you are looking to buy now - you could probably knock a bit more off the price i got since the new '08 models are coming in very soon. some reports say as early as august. i believe the only major addition the '08 has is the tire pressure monitor.
  • patpat Member Posts: 10,421
    It would be a good idea to read the "rules sticky" since you've already agreed to abide by everything it encompasses. ;) There's a link at the bottom of the page.

    And p.s., dealer names are okay, but please do read the membership agreement...
  • cz75cz75 Member Posts: 210
    ????

    I guess having Honda link you to your dealer's parts dept. (assuming they even participate, my immediate local dealers don't) and having to pay high prices for the parts instead of cost + 10% is waaaay more convenient. I can only surmise you didn't bother to look at either website past the intro page, as each site is a full service dealer with all available Honda parts.

    Me? I prefer to buy my genuine parts at the cheapest sources on the 'net and having to go to a dealer website instead of using Honda as an intermediary is no inconvenience at all.
  • eldainoeldaino Member Posts: 1,618
    rev hang is dbw, nothing to with the oil.
  • eldainoeldaino Member Posts: 1,618
    and why i'll be eternally jealous.

    as nice as the si sedan is, the euro civic and civic type r are the nicest looking civics ever made; so original and un-bland!

    while the jdm civic type r (looks similar to our si sedan but with a nicer loooking nose) is a bit nicer from a performance standpoint, the type r in europe is one incredibly designed car.
  • themistoclesthemistocles Member Posts: 95
    Im really not a hatchback fan, I think there ugly. Although that europe hatch is definitely the best looking one, Id still prefer the coupe style.
  • aaronr121aaronr121 Member Posts: 91
    You are right the prices on those sites are really good. I'm excited that a manufacturer offers such an easy way to find and look up the parts.

    10% over cost is always good. That was the best thing about working at a Ford dealer back when I was a kid.

    After spending the past 8 years searching for parts for our '98 VW, I just think this is great.

    There are lot's of places to find late model VW parts, but I haven't come across any dealerships offering such a nice searchable database. You can't believe the number of trim items I've had to replace since new. For those items, I'm stuck calling the local dealer or stopping by after work.

    I've ordered a few accesories for the SI from one dealer, they had great discounts. But they only offered accessories, no replacement parts.

    Forgive me for jumping on ya. I was just excited.
  • eldainoeldaino Member Posts: 1,618
    compared to the euro hatchback, the sedan AND coupe versions look very mainstream and unexciting.

    I know you don't like hatchbacks, but remember even the first si's were EXCLUSIVELY hatchbacks.

    Not to mention that even the euro Type R would give our si's a run for their money;

    they weigh less,
    have slightly more hp and torque
    hit their peak hp and tq LOWER in the rpm range
    and while lacking a limited slip, have finer tuned suspensions and MUCH wider tires and an interior that simply OWNS.
  • themistoclesthemistocles Member Posts: 95
    Anyone know which intake to get for 06-07 Si, Short ram or AEM cold air intake?? im thinking cold air intake since it doesnt suck up hot air next to the engine like the short ram, but i heard short rams are better for some cars
    thanks you

    Ive had my 2007 Civic Si Sedan for just over a month now and she keeps getting better. The shifter is much smoother now, the clutch engages smoother, and the exhaust seems to be a bit throatier. Not one rattle or anything. The rev hang isnt really an issue anymore though, ive grown used to it.

    awesome pics blairspeed! the silver is one of the few 'regular' civic colors that looks good on the si.

    cz75 above in his post has pointed me to the TVTEC site which is another Civic Si place. Found this link on Si performance test videos:

  • cz75cz75 Member Posts: 210
    I see the TL-S can pretty much only get away in the straights or because of the Si fading its brakes. First week I owned the car I changed to Axxis Ultimate pads b/c I have no faith in Honda OEMs being anything more than for quiet operation, same as the mediocre standard A/S Michelins
