Should i VTEC my engine or Turbo

[G.C]

I have a Jdm f22b non Vtec in my prelude rite now and wondering if i should Vtec it or put a turbo in it. Im looking for speed + reliable kind of thing. Dont want engine to blow up or r.i.p on me , but want speed.

[BlkCD5]

Turbo. You'd be happier with it. Run low boost, tune the car and you shouldn't have reliability issues. Are you going to do the work yourself?

[chituntang]

Vtec first, then turbo.

The only thing about vtec is you should not believe vtec will give you power full range. You can with a turbo setup though beside turbo lag and if you only drive outside the boost range.

[AnclyT]

vtec is overrated.

just boost it

[Fox351]

I think you should Vtec it just to have that badass feeling at about 5000 rpm when it puts you in the seat and then you feel around the same time that you hit full boost and you instantly feel better about who you are.

[BlkCD5]

that makes no ****ing sense!

LOL!!!! He referring to that JDM MAD V-TAK!

He has a SOHC motor and all them kick in before 5000..lol and a SOHC vtec isnt gonna put you back in the seat..you wont even be able to hardly tell when it engages vtec.

The jdm F22b is not sohc.

[allmotoronly]

The jdm F22b is not sohc.

but it is also not worth sh1t IMHO. If you want to go VTEC and keep reliability, just get a whole new engine (I recommend the F20B from a jdm accord SiR-T. It is basically a H22A type S with steel sleeves and a shorter stroke. Everything else is the same, and you can usually find it for cheaper. It has 200hp like a H22A, and a 8k rpm redline. Pretty badass little motor), or if you want to go turbo, go with a H23A and turbo it. You can get those engines pretty cheap, and parts are fairly priced. The F22B is just not worth doing a VTEC conversion. It will probably cost you close to a grand for just the VTEC conversion alone, and you probably won't pick up much power since it has a lower compression ratio. Also if I remember right, it has a smaller crankshaft main journal diameter than the H series or the F20B DOHC VTEC. It just wasn't designed to turn 8k+ rpm. VTEC engines make the most power in the high RPM range that a F22B is not capable of going (reliably anyway).

jdm f22b isn't sohc. its dohc.

[BlkCD5]

last time i checked, F22B and H23 were just about the same in price. You're right about the Vtec conversion, but its not a bad candidate for boost. How can you say the F22b is "****", when there is not much difference between the two motors?

that is best qoute ever.

that is best qoute ever.

its definintly sig worthy, but my sig is better so i didnt quote it

[brittoknee]

and you instantly feel better about who you are.

LMAO.... hahahahahaa


gah what a loser

[BlkCD5]

^ . Brittonee, could you give him some enlightenment on the Vtec head conversion. I heard that you had a H23 block with a H22 head.

[cdhtang]

Vtec and supercharge it, supercharge have a better line than turbo(smoother) imo.

[Berta]

I would boost it. More bang than changing it to vtec. Get a good fuel management and get it tuned by someone respectable. It will last a long time with no issues.

[scttydb411]

boost it. get a good properly sized turbo for your goals and don't go overboard and you can have a good power band for the street and still be reliable.

[an0therh22]

H22. nah just swap to an h23 and boost the hell out of it. thats what i would recommend. if i had the chance again thats what i would do instead of an h22.

[G.C]

ok guys thxs for the support. i guess no one loves my engine. poor f22b.

[chituntang]

It's not that no one loves your engine. Just there is not much more before the engine is at its limit.

[G.C]

i will think about swap then. do you guys have any idea how much it would cost me to drop the engine in the car ?? i can get the engine from internet or something but have no idea how much it would cost to install it. thxs.

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..

Way to be a complete n00b and call out a forum full of people you don't know **** about and then covering your ass to say "but some of these guys really know their stuff". Please, just GTFO with your infoless post.

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.

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

it doesnt have strokes or cycles. It is one continuous cycle. The rotor is 3 sided. While it spins, one side is pulling air in, one side is compressing and combusting, and one side is pushing exhaust gas out.

[allmotoronly]

dont believe everything you read on the internet. There nothing to stroke. A stroke = up and down motion. The rotor spins on an ofset gear. If anything it is a wobble, not a stroke. That article was comparing the action to strokes, not saying that it was actually a 4 stroke engine. A rotary engine has 3 CYCLES, not strokes....
lololol you have proven nothing but the fact that you don't know what you are talking about and you have to use google to supply your facts. That article is either extremely dumbed down so that the average person could vaguely grasp the concept of a rotary engine, or it was written by someone who has never even seen a rotary engine

This is not talking about masturbation terms,
this is talking about automotive terms, a stroke is the part of the cycle an engine takes to complete its cycle, thus itake, compression, power, exhaust stroke to complete one cycle. a rotary has four strokes, not wobbles, it takes a standard piston engine 360 degrees to complete a cycle, which it takes a rotary 1080 degrees to complete its cycle, why? because it has longer strokes than a piston engine, wich equals to more power, and more heat.
And if you belive you are smarter than the man who invented the rotary engine Dr. Felix Wankel, because that was a paragraph of his interpretation of the rotary than that is very smart..

think about what you are saying. It has cycles, not strokes. You say it has to go 1080 degrees to make one stroke... that makes no sense either. It goes through a full cycle on each revolution. The fact that the rotor turns 3 times for each revolution of the E-shaft has nothing to do with the cycle. As I have already said, It has cycles, not strokes. If it had strokes, then it would be one continuous stroke since the rotor keeps turning and the cycle is constant.

dude, you've been pwning yourself in almost all your posts saying the same thing he says and twisting it to make it sound like you are right and he is wrong. Give it up, chava, allmotor knows more about the rotary than you.

VTEC is now a verb, Nice!
