VTEC vs. NON-VTEC: Pros and Cons For Both.

[AsheCb7]

well one con with vtec as far as allout drag goes, like the 7 scond guys. The vtec system uses oil and there are oil pressure probs with vtec and big turbos or even the all motor dude with vtec you run into oil pressure fluctuation with crazy setups. but as far as dailies and dual purpose use vtec is the shit.

The large oil capacity decreases oil temps at high rpms. There is also an increased need for oil due to the fact that the entire VTEC system uses oil to work everything. Plus, they are being safe. The engine will actually survive on a lot less, but what if you blow an oil filter and realize it right away. That extra oil might buy you the time you need.

VTEC advantages:
Can run more aggressive cams on VTEC side while maintaining a very streetable cam on Non VTEC side.
Saves gas and cheats emisions

Non-Vtec advantages:
Cost Effective
More abundance


My solution to people who want Vtec but dont want to pay the inflated price:

1. Do a Wikked Hybrid
2. Stay Non-Vtec and buy a big cam (my preference)
3. Slap Vtec stickers in front of the rear wheelwells and lie to yourself.

My h22 burn no oil and as for the car gets louder when vtec kicks in i love it and why would you want vtec to engage when the engine light is on.the engine light on is a sign of trouble slow down check it out not hit it hard and burn it up.

YO WHERE HAVE YOU BEEN!!! LOL i haven't seen your car around in forever. you still down in the 20653??

[accord"R"]

i put 4 when i change my oil, and it shows that it is almost full, doesnt 5.5 are harder on ur engine. And does enybody use Royal Purple , i heard it was very good.

The main disadvantage to VTEC is cost. It is technologically more advanced, which means there is less compromise in the tuning. That's why they make such crazy HP and are still driveable.

I don't really think reliability is too much of a concern, because they have proven over 15 years of hard use, that they still don't really break that often.

Unfriendliness to boost is perhaps another downside, but that depends on whether or not you want to boost. All DOHC VTECS have high compression, and the Nikasil cylinder linings on the H series are not compatible with forged parts, so if you want to seriously boost reliably, then you will probably have to redo the bottom end.

Other than that, there aren't any.

I'm not partial to either. I think you're overall setup is more important and just because you have either, does not mean your faster. VTEC in itself means nothing, unless it's one of the performance oriented VTEC systems (i.e. 5th gen Accord VTEC vs H22 VTEC/GSR VTEC). On a non-VTEC you can usually get performance camshafts/regrinds for it. However, on the VTEC systems usually the performance camshafts are significantly more expensive. The concept of VTEC is nice though and with a non-VTEC setup you have to sacrifice some comforts to use a performance camshaft (depending on how extreme you go) because you either do it or you don't.

Instead of making it a VTEC vs non-VTEC, why not just simply list the pros & cons. Like I said before, you're overall setup is what's more important, not whether you have VTEC or not.

i think vtec burns more oil than non-vtec motors. dont ask me how cuz i dont know. possibly oil capacity is more? not really a con but maybe on money when u gotta buy more oil LOL. also ur car gets louder when vtec kicks in... con to ppl who dont like loud cars. also one more thing to fix if it breaks. rumor has it vtec doesnt engage when the check engine light is on... which could mean less power in upper range but still maintain the good gas mileage on daily... but depending on what code is being thrown out.

Im going to even though I dont need to point out that this guy is an idiot.

and the H22 is supposed to get 5.5qts even though I run 5.

and why have an H23 when you can have H22 some people just dont get it. Vtec hands down owns all and the people who bash are just jealous becasue they either cant afford it or their complete morons.

[DUNKiNUTS]

i have a 3.0L V6 and i only put in 5 but it says 4.5. So i run my oil a bit longer to maybe 4-5K rather then 3K

[accord"R"]

does that actually make your engine perform better, or why does it need so much? I use only 4 - 4.5

[JDMcb7]

WTF!!! 5.5 quartz!!! ummm due big block V8s take that much oil! ur only 2.2 liter......hmmm are u sure about that! too much oil isnt good for ur engine!
-Sean

Yes, that is absolutely correct. I used to work at a local honda dealership and that is what we were required to put in. 5.5qts (h22's only) does sound a bit crazy but it is in fact true.

[k-mart]

VTEC = All of the lag, none of the turbo

[g-wagon]

well i think the real question is DOHC vtec DOHC non-vtec. Its to hard to compare SOHC and DOHC. But two DOHC one vtec the other not. that is a better question.

yea....i rode in a sohc vtec civic today... it was pretty strait..... umm.... now.... if your dohc.... h23>h22
























not really..... but i <3 my h23 head
