Did a serach but nothing came up.

1. I heard that the 2007 Accord EX 4cyl iTech is now a timing chain instead of timing belt? Is this true?
If it is, my understanding of timing belts is that it's quieter and easier to replace. Timing chains on the other hand costs more to replace.

2. Is the 2007 4cyl iTech an interference engine? how similar is this to the 2003 model?

Thanks

 

So I found out that the 07 accord EX has the I-VTEC engine and the 06 accord EX has the VTEC engine. I read a few articles about the I-VTEC on the web and it seems like a good thing. Has anyone had any personal experience with this new I-VTEC? how different does it feel from the regular VTEC and is it worth the extra $$$?

 

I-VTEC has been around for a while. I do believe, don't quote me, but I do believe all I-VTEC engines use timing chains. You cannot just get "VTEC" in a new car anymore.. Yes, It's a good thing...

 

Wow, a lot of misinformation floating around here.

The 2007 Accord 4 cyl has a slightly tweaked version of the same exact engine the 03-06 4 cyl has. They also have i-VTEC, it is not new for 07.

ALSO, yes you CAN get a new Honda engine with the regular VTEC. It's called pretty much every V6 they make.

 

As stated above...4 cyl accords got the K24 in the 03 body change. All K series use the timing chain. As far as price on changing the timing chain goes...believe it or not Honda does not have a schedule on when it is due. Also they do not recommend a valve adjust until the valves are "noisy".

Ah, yea, well.. I figured the OP was talking about 4cyls, and you can't get VTEC in a 4cyl, can you?

 

The 07 has the k24a8 like the 06 had, the 03-05 had k24a4's. Only huge difference is drive by wire which the TSX k24a2 engines have.

i-VTEC basically means you're always in VTEC, as opposed to older cars where you could hear and feel the changeover (from what I've heard).

Actually, I have noticed a lot of old school HT guys, myself included, almost always default to the 4 cyl as most of us don't even think much about the V6.

you guys arent talking about the correct year car.

the 07 you're talking about is really the '06 which only has 6hp over the previouse and not exactly sure on tourque difference, but '06 facelift version of 03-05 does have the k24a8 (read the tag on side of engine block).

its fitted with an i-vtec which is also in the s2000 but im sure the engine is diff, system the same.

my parents have a 95 lx accord 4cyl, and my brother has 96 ex 4cyl accord, both are sedans... ive experiance driving them quite a bit and when i have to compare their Vtec engines to my i-Vtec engine... i would say that the changeover is not felt that much (but the auto downshift "kickdown" im sure jumps), cept the i-vtec has a higher pitch roar to it, and it picks up alot faster.

i need to mention that my accord is manuel and those other older accords are both auto.

i dont know on the95 96 accords but my 06 i-Vtec kicks in around 4500rpm, the noise changes quite suddenly and you definately feel the power go honda

 

5th gen lx accords have the f22b2 sohc non-vtec engine. The ex models have the f22b1 sohc vtec engine.

 

thats why the 96 ex accord seems like itll tear the 95 lx apart... thanks for clearing that up.

and this whole time i thought my moms car was over its hill, thers like 180k on it atm.

 

Yeah it's not a huge dif but you can definitly tell. I think the b1 has like 145 hp and 149 tq and the b2 is like 130 hp and 139 tq.

 

btw my 4cyl 5spd 2006 accord coupe is faster than those mitsu lancer ralli art, i think it was modded with catback exhaust and intake, short or cai i dont know.

and the only stock car barely faster than my accord is the nissan sentra SE-R, i dont know why because se-r should dip on me, but it doesnt, but sentra's governer turns on later

btw the 2006 accord governer is 130mph.
hit limit on 52 west, SD, ca, down a 4 mile hill

Actually I am talking about the correct car. The 06 model came out with the changes and like stated above the 07 just carries on those changes. Were you not aware that the 07 is out?

 

the guy at the honda dealer told me that the timing chains are good for 300,000kms

 

timing chains USUALLY last the life of the engine so I would not be too worried about it...Honda knows their stuff when it comes to engines

 

That's good to know. I decided to buy the 07 Accord EX 4cyl 5spd. This car feels very different from my prior 98 accord. The engine seems to respond well at low rpms and since i'm still breaking the car in, I haven't gone above 3500 rpms to feel the full power. 5sp seems to shift very well and the thing that stood out mostly is less body roll. The 07 seems to have a lot less body roll than the previous accords that I've driven. The dealer told me that the suspension is different from the 06 model. I'm just waiting till I get over the break in period so that i can revv it higher.

 

Once again the dealer was wrong. The 06 and 07 suspension is improved over the 03-05. The 06 and 07 are mechanically identical and are just slightly different than the 03-05 with a bit more power and a more taut suspension.

 

heh &gt;&lt; no i wasnt aware the 07 came out, when i read the post i thought that people were sayin the 07 is different from the 06. my mistake.

i've had my 06 2dr 4cyl accord for pretty much 1 full year, put 30k on it....

umm and i broke it in when i drove off the lot, and its still a beast.
...yes i did noob it just a tad, first car in stickshift. and i didnt know u were supposed to baby bra-new cars heh...
ill take that into account when i have enough to buy my 2007-08 skyline .... i wish.
