i have heard that honda built a sohc vtec , just wondering if it was fitted in the 1993 2.2 accord as my friend had a filter fitted and at 5000rpm it has a kick and a deeper grunt just like my prelude but not as deep and long is this a sohc vtec if not what is it and what does it do ? i have no knowlage of this engine so if anyone can give me some info to pass on that would be great cheers .

 

Im still learnign about Honda Engines but ill give it my best shot:

SOHC = Single Over Head Cam
VTEC = an engine technology in which at 5000 rpm has more then one piston firing at a time to get double the engine output.

Correct me if i am wrong guru's

Im not sure if its in the engine you currently have though.

 

I'd go to http://www.accordinglydone.com and look up engine codes. There's a list of the different generations of accords, the engines in them, and a few engines that are popularly swapped in.

 

http://www.leecao.com/honda/vtec/sohcvtec.html

should explain everything

you couldnt be less correct on the vtec thing .....vtec is varaible valve timing, aka, once you hit vtec, the time valves are open is changed by a 3rd lobe on the cam shaft.....on SOHC motors, its variable, and doesnt have a set point like it does on DOHC......

if the car was origionaly manufactured for the asian market, it might have the f22b1 (5th gens started in 93 in asia)....

 

ya that ^

 

Wrong on all SOHC Vtec there IS a set point.

maybe its different for the v6 sohc's, but would you like to tell me what it is than....i was just in my car 5 min ago....can you explian why i could rev it up to 6k and vtec didnt engage???, or how i can get it to engage around 3.5k???...oh, thats right, its based on throttle position (among other things)

 

i believe u are referring to the F22 motor which is the single overhead cam v-tec. it produces 150 hp. basically 94-97 Ex accords & 98+ Lx, Ex 4 cyl have the same motor.

actually:
98-02 accord EX and LX have the F23A1 or 4 (4 is the ULEV motor)
98-02 accord DX has the F23A5
03+ accord have the k24

though the same series, their not the same......(disp, compression, and stroke are different, for example)

sohc vtecs need all the other prerequisites as a dohc motor for vtec to engage, but you need to have the throttle wide open.

 

Fact:

90-93 Accords do not have a VTEC solenoid
F22B1 came in 94-97 EX models

F22B2 (if I'm not mistaken) is th 94-97 LX (non-VTEC) models might be the same back from 90-93

good job posting a bunch of engine specs, half of which are misslabled blocks, or incorrect info.....

 

k24 came in 2003 accord not the 2002

 

all i know is that my 94 accord ex has vtec, i think that was the first year that it was offered, but only on the ex version.

 

ive got a 95 ex accord coupe and it is a 2.2 Ltr SOHC Vtec. So in answer yes your friend most likely has the f22 engine as i do.

you have no clue what your talking about......in the US accords changed chasis, body style, and engine from the 93-94 model years..........therefore he has a 4th gen, and thus an f22a....which means NO vtec.......honestly, know what your talking about.....

just pop the ******* hood.....if it says <FONT SIZE="12">VTEC</FONT> and the spark plugs are entering from the front end of the car, then its an F22b1 (which it isnt unless you car is ADM / swapped)

Just pulled it off a site. Guess the internet isn't as reliable as we'd like it to be.

That is the worst bunch of information I have ever seen Almost all of it is incorrect.....

 

http://www.geocities.com/wyvnz/Engines2.html

Here's where I got it. Someone tell me which ones are wrong. Thanks.

 

ok you have to remember im in the uk and he has a f22 engine duno which on but at just over 5k it grunts more and pulls harder it doesnt say vtec on it any wear but it sure does sound like one and is a fast car for a 4th gen thats all

 

if you look at the engine code, you could easily tell exactly which motor you have. the easiest place to look in at the engine block (distributor side) just a bit below were the head/ block meet... its stamped with the designation of your motor (it will say f22xx and the xx will be the letter and number combination).

the power at 5k is cause your coming through the peak of the powerband... check out some stock f22 dyno charts and you will see what I mean.

btw just to add... vtec engagement varies on the f22b1... I have watched the ecu's vtec signal output and can tell you that for a fact.

I don't see anything incorrect about that information.

Please explain

 

i don't know how it is on the f22 vtec, but on the f23, vtec engagement is based on load, throttle position, coolant temp, rpm, and mph. which means vtec can engage as low as 2200 rpms (an example would be 2nd gear rolling starts with 50% throttle).
