So I'm finally back into Honda's. Just picked up a new 08 SI sedan. The car currently has 250 miles on it, had about 50 when I got it. It doesn't seem that powerfull in the upper RPM's and too be honest I don't feel or even here any real VTEC engagement.

So I was wondering if with the DBW and other electronic controls the ECU has does it keep me from going full throttle until the engine has some miles on it? The dealership also filled the gas tank when we bought it so they may have put in 87 pee water, as opposed to the 93 I'll use. Anyone notice issues with 87 octane on this high comp motor?

My Lotus has about the same spec engine, 11:1 compression ratio, VTEC engagement (VVTL-i actually) at 5200 RPM, so I am familiar with what VTEC should sound and feel like....but I'm just not seeing it with this car. The mid range is nice, but it seems to fall on its face in upper RPM's.

Anyways other then that, love the car. LOVE the shifting...so smooth compared to the SRT-4 I had and the MazdaSpeed 3 I testdrove. The interior is layed out pretty well too.

 

maybe u should put oil in it.

or wait till the engine fully warms up before u step on it.

 

I am not referring to cold start...I know that.

 

well put oil in it.

 

that seems like an odd problem. I've never had that issue and I bought the car brand new.

Maybe yer car is bunk and you should take it back?

 

I hope they didn't use anything less than 91 octane...this high comp motor needs the premium. Also, I was wondering why he would want to put in oil???

Low oil pressure will not allow VTEC to engage.

also, these engines are known to burn a lil oil before its first oil change.

 

the main problems are 1. the fuel and probably 2. your expectations.

it's not that powerful considering the weight of the car, and it's just not all that fast as a package, so i am unsure of what you expected. did you drive another Si before yours to which you are comparing? getting in an ms3 and SRT4 before an Si will make an Si feel slow, but Si vs. Si, if that is what's going on, is what i'm curious about in your situation.

you should hear/feel the vtec crossover pretty distinctly, but dude, to be honest, i'd get 93 in there as soon as possible and break in the engine as indicated in the owner's manual. why press the issue when you know you have **** fuel and it's not broken in?

 

1.) kick your dealer in the ***** for potnetially ruining your car with sh!tty gas.
2.) break yours cars in right &lt;--- no cruise control, NO VTECH for at least 500 miles. You gas mileage will thank you in the long run.

I'm not auto-genius like most of you guys, but aren't the two cars in the OP's pic in tow totally different universes?

 

Well, if the car is behaving as it should and its just you not feeling it, then maybe its not the car for you? The VTEC isn't like it used to be. It's not controlled by oil pressure, it still checks to make sure pressure is at safe levels, but VTEC is strictly engaged by the ECU now. So its not such a 'kick' as it is a smoother transfer.

These cars really aren't "fast" but they handle like a dream... then again, I hear lotus' do as well, but then again... they aren't in the same class either.

computer removes timing in the event of low octane gas so there won't be that potential for damage. At most dealers when you get that first "free tank" of gas, they put in 87. I know mine did

break in period and methods are highly debated: read this on break in secrets

and seriously jaepalm, "VTECH" really? It's written on the side of your car and you still can't spell it right

he's not serious you silly goose!

haha

but, regarding that first tank issue, i hate that ****. why don't they leave you the option, if the car isn't full, of getting your own damn gas? they pulled that **** with me on the Si and the Mazda. i specifically said don't fill that bitch up with ****; just leave what's in there and i'll start on my way to detoxing the freakin' car by topping off with 93. did they listen? no.

 

If you drive a Lotus which weighs 600lbs? less than the civic then it will feel less powerful...

my vote is for option 2. not living up to expectations?

The Lotus has the engine from the Celica GTS with some minor changes. The Si engine is arguably better...

i'd say they are compareable in terms of durability ,but only on the engine side; if equipped with a TRD or compareable LSD, i'd take the Toyota trans over the Honda trans any day. I firmly believe the Honda design with these 6-spd transmissions is inherently flawed.

I'd like to go with option 2

I swear there's some people that think the Si is the quickness!!!

The ECU always controlled VTEC. Oil pressure is used to lock rocker arms to run on the secondary cam lobe. Has the basic function of VTEC changed b/w the B and K. Because if it has then I've been an idoit for the past 6 years. Last I remember all the basic functions are the same with the addition of VTC

Just over a 1000 pounds less....car weighed in at 1928 pounds. The K20 is a better engine then a 2ZZ.

I checked the oil level and it was fine. The car FINALLY got down to 2 ticks left on fuel gauge, so I will able to give it real gas.

I don't expect this car to be overly fast, but I do know ther should be a noticable torque change. To be honest though I have not really gotten on it 100% save for maybe once or twice, more like 75-80% most of the times I have tried to get on it. Mostly from the new engine and mostly cause I know they most likely put the cheap crap in there.

theres your problem. lol vtec engages when ur nearly full throttle.

 

yeah, i gave up on this thread when i saw that

 

Nice choice on the Exiege
