Should i VTEC my engine or Turbo

[allmotoronly]

All this Vtec talk, when Vtec ain't ****! First of all half of the people, in this forum coul not tell you what Vtec is or how it works, and asking for advise about his build from the wrong people, but some of this guys realy know their stuff, just Vtec wont even shave a second from your time slips, and it wont put you back in your seat, depending on how your engine is built you will barely be able to feel it, so you do the math..

now for the rest of you just cuz you can read and article about Vtec, that does not mean that you are a Vtec guru so unless you are ASE sertefied as a VTAC technician let some body that knows their stuff give some advice to the guy..

You are obviously one of the people on here with no clue what VTEC is or how it works.... Theres no such thing as ASE certification to work on a VTEC vehicle.

In a well built engine you shouldn't be able to feel the vtec engagement. It is SUPPOSED to be smooth and will have a smooth power curve. Who ever said it was supposed to throw you back in your seat. Its not nitrous oxide. The point of VTEC is to make more power at higher RPM's.

Stick to your rotary engines with their 3 moving parts since a normal internal combustion engine with a little extra technology is too hard for you to comprehend.

first of all that statement is called sarcasm! and second, motha****a please, I went to compeat to an auto service competition at a state level, i know more about a piston engine than what you read on books, and for your information a rotary engine IS A NORMAL INTERNAL COMBUSTION ENGINE! ****ing dumn ****, it works on the same principals as piston engine, and the modern rotary engine has more technology than all your little GSR, LS, K20, B16's, have put togather!

So go google Rotary engine and see how it does everything a piston engine does, just that it does it better, just how ur sister sucks my **** better than ur mom.

look you ignorant b@stard, a rotary engine is a WANKEL combustion engine, not a standard internal combustion engine. It does not work on the same principles as a normal combustion engine. You need to just shut the hell up before you make yourself look even more like an idiot. I dont give a **** about you going to compete at a auto service competition. I knew guys in highschool who were book smart about cars and went to the state competitions, and they were still a bunch of idiots when it comes to hands on work.

I didnt get the knowledge I have on building engines from a book, I got it from hands on experience over the last 10 years. I also guarantee you I know more about your wankel engine than you will ever know. It is widely known that rotary engines are not very efficient. Think about it. its a 1.3L that gets worse gas mileage than a 4 wheel drive truck...

Basically what I am trying to say is I have forgotten more about cars than you will ever know. I've said all there is to say. you can argue for another 3 hours, but it won't do you any good. I have better **** to do than argue with someone who doesn't know what they are talking about.

A rotary is a Wankel combustion engine!!!!!

Damn you have so much experience!! im soooo sorry!

I would not want you working on my car!

man wankel is a nick name for the rotary engine, a rotary IS an internal combustion engine, it has four strokes just like a piston engine and nex time take my advise, google the subject and read a little befor you look like a dumn **** like you do now!!!

lolollololol rotary's dont have ANY strokes. just shut the hell up. Dr Wankel designed the rotary engine in Germany in the 50's. Rotary is a nick name for the Wankel engine. I never said it wasn't internal combustion, I said it wasn't a STANDARD internal combustion engine.

You are the one who needs to read.

Rotary Engine Power

Rotary engines use the four-stroke combustion cycle, which is the same cycle that four-stroke piston engines use. But in a rotary engine, this is accomplished in a completely different way.


The heart of a rotary engine is the rotor. This is roughly the equivalent of the pistons in a piston engine. The rotor is mounted on a large circular lobe on the output shaft. This lobe is offset from the centerline of the shaft and acts like the crank handle on a winch, giving the rotor the leverage it needs to turn the output shaft. As the rotor orbits inside the housing, it pushes the lobe around in tight circles, turning three times for every one revolution of the rotor.

Your browser does not support JavaScript or it is disabled.
If you watch carefully, you'll see the offset lobe on the output shaft spinning three times for every complete revolution of the rotor.

now this is too much work read this cuz im not about to type a whole explenation,
so go **** yourself cuz im out.. and look closely those are called strokes!!

I wanted to quote this as a "well built VTEC engine" will still have the "throw you back in your seat" because it is the engine management that makes the vtec works in the first place. You can tune the engine to make it less noticeable, but not replace some parts to make it go away.

I also think rotory engine is more complex than a piston engine.

Wankel (Rotary) engines are not more complex, just more complicated. It only has a handfull of moving parts. Its a simple concept that it hard to understand compared to the standard OTTO cycle engine... Two rotors spin on an eccentric shaft that has 1/3 the amount of teeth as the rotor, which makes for a 3:1 increase. The shaft spins three times for every single revoluton of the rotor. When the rotor spins, it wobbles around this shaft in a way that causes it to compress the air fuel mixture. I will try to find a vid. you have to see to understand.

heres a vid. Its a little crappy, but the general idea is expressed well
