ok...im debating wether or not i should stay with a single cam...or a DOHC, it isnt based on price or labor or anything. I just want any of ur input on what i should do. I would like to buy a hatch by the end of winter, and im plannin out the **** right now, and the only thing i really cant get straight is what motor to have...is staying SOHC good enough, if i do some work on it, or should i go all out and just buy a DOHC?? this might sound like a retarted answer, but im just curious as how good the single cam engine can me, and if its worth all the trouble to buy one, especially if i wanna do some 1/4 mile and just have an all out fast hatch...

thanx to you who can help...

The F22 bolt in kit is coming soon Stay single cam and give the DOHC fellas something to cry about haha....

 

i would say go with a dohc swap, single cam built is good if you wanna see yourself as a sleeper to impress peeps when you pop your hood and they see its just a sohc motor. but in the end you ll end up spending tons of money to produce numbers a stock dohc motor already has.

 

Spend hundreds of dollars for on an SOHC engine to produce the same amount of power? Hmm how about the accord motor.... Show me a DOHC besides the H22a that produces more than 147 lb/ft of torque from the factory. Please let me know when you find out the information. Have a nice day.

 

ParrisEngDyn, im talkin d16z6...no accord motor, i know u prolly know that, but id rather have the d16 if i go SOHC

 

i give a lot of credit to some of the high hp DOHC motors out there. but i'm a SOHC guy. i guess i like doing things the hardway and being the underdog. it feels good to be just as quick as a lot of the DOHC guys out there with just a 1.6

 

If you are planning on using a D series motor, use a p&p a6 head with a wild cam, valve springs and pistons. Sticking with the Vtec head will only add unwanted rotating mass in the valvetrain. The weight of the motor alone is a great benefit too. Of course a DOHC motor is going to provide a great platform for building a motor. All of our race motors are DOHC . However, you can build a mean SOHC on a budget. There are many resources here on this forum and others. Think of a goal and go from there.

ok i was talking bout the sohc on his civic
but if your talking bout the f22 sohc then thats basically putting a swap,and same thing for the accord sohc engine you can spend a ton of money on it and still only make numbers a stock dohc h22 motor will make .have a nice day

 

It depends on your goals. If you are going to drag race I would go with SOHC turbo unless you have enought to go DOHC turbo.

If you want something reliable that you are going to drive every day, then just throw in a DOHC and call it good!

That's what I would do!

not really. the sohc doesn't have as much potential as a dohc setup, but it all depends on what his goals are. He could easily spend half what a swap would cost and put down the same numbers with a n/a sohc setup.

However if this guy wants a fast track car, then a turbo is most likely the cheapest way to get there. He is going to have to build a d-series engine to get good numbers. Again, depends on how fast he wants to go and how deep his pockets are.

 

For any SOHC needs or questions, contact Speed Machine Racing 760-746-3117. All I have to say is 181 whp out of an ALL MOTOR 1.6L SOHC. http://www.speedmachineracing.com

I fail to see the logic behind your comment. I hate to urinate on your parade, but the port layout of the F series engines are superior to the H series. As you take apart an F series engine, you will realize that it is heavily detuned from factory.

Air has no idea if you have a sohc or dohc. Your power is dictated by airflow, and friction losses. Guess what?! Dohc engines do have higher friction losses in the valvetrain/head than sohc's, despite the lobe sepration adjustibility advantages.

As always, if you purchase and build with the right people, you would not make mistakes and spend ungodly amounts of money.

It would be ideal if people provide facts from experience, and accurate data than seat of the pants or gut feeling of the day!

Stay SOHC... DOHC is way over rated.

 

me im all for both ...i love DOHC but SOHC isnt bad either ...after i finish my motor and 1 or 2 more projects i got in mind ...i want to build a nice sigle cam vtec motor just for the street nothing crazy ...i think they have potential ...theres a kid around my way that im cool with he was a 96-00 four door i forget what year exactly but he has a 1.6 single cam vtec with intake header exhaust and a clutch ...and its quik ive seen him beat a few si's and 1 newer si and a few Ls's ...his 4 door just moves for some reason ...and he swears he doesnt sprey(which he has poped his hood and proved) or have any other work done than what i told you ...maybe hes just a nasty driver of the other people couldnt drive but it just gotes to show that single cams have potential too....but do what you think is best and what suits your budget best ya know ...a fast single cam is a good sleeper ...

 

 

SWAP that Bitch B Series OwNs

as much as Bisi is correct and he should know with his numbers and experience, you have to keep in mind that building a sohc motor that can compete with a built b, or h series motor, i just insanely expensive and that the parts are not as readily available, as well, hondas d series motors werent built or designed with performance in mind but rather economy, so the rotating assemblies in those motors arent going to hold up to the stress of crazy power, and high rpm's without alot of very expensive work, and dont get me wrong i know that a b-series motor can only take so much, every motor has its limits but in general hondas dohc motors were built more with performance in mind than economy as the d-series motors were. im not saying it cant be done, take bisi for example, but that to really build not just a motor but a whole car (because you cant build just a motor, the car needs to be able to put the power on the ground, etc.) its just not cost effective to build a sohc car. a dohc car with comparable times for the average(non-professional race team) consumer is just so much cheaper after the initial investment for the swap. And this is not by the seat of my pants believe me i had more fun and headaches with my crx until it got stolen than i can ever forget. But again its up to each individual to do what suits him best, and what he can afford. So i have no suggestion other than to do some real research and get the facts not just what you hear on honda tech, talk to the people that know, and bisi is a good start, but you should get multiple opinions and just try stuff out find out what you like.thats all i can say.

By the way- wow bisi, insane 10.0, thats crazy, sucks your motor went but that time is out of hand, good job

i my Honda

Who on here is pulling 13's w/an NA D16? What mods?

 

Stay sohc if youd like. I dont see many of them. Theres a few, like Spade and exospeed to name 2, who rep the sohc. Get you a good cam, some high *** compression, headwork, youll be set.

I can only agree with you around readily available parts.

As for cost, it was cheaper for me to build my D series to run 10s than my DOHC peers. From the cams that are so expensive for the B-series (versus 60% less for my sohc) to the pistons (d motors are slightly cheaper) to rods (same price). Fuel management was a big plus, economically, since I used carbs vs. injection.
Why have I stayed unibody? Besides the props, it is much cheaper!

I am at an advantage because I have built both B and D series engines. Those who know me personally can vouch that I am very frugal /cheap when it come to this hobby of mine. The challange was parts being available, but that was not a problem for me: I love challanges and experimentation!!

Whether its with D, B, H, F, or K unnecessary expenses can be avoided if you go to the right people the 1st time, and have a realistic performance plan. Do research, talk to racers, and ask shops about the best and most performance vehicles that they have turned out at their shop.

And when going all motor, make sure these are "all motor" cars that they have worked on: sleeving, headwork, tuning, etc.

People may think we have a pro-team based on our success, but this is my hobby, and I love designing, tuning, racing and research. I'm still the little guy!

Thank for the kind words around my testing. I was there to test 60ft, and broke my clutch after my 86th pass on it. Its a wonder that the clutch lasted that long. My peers change clutches after almost every event!

I can't wait to go alcohol, like everyone else in pro all motor.

Im sure the carbs make a ton of difference. I would love to have a build D in a street car. Very quick motor that many would sleep on.

 

I say stick D.
I'm hoping to build my z6 a bit if I can't sell it before I leave..

 

Good info Bisi. I had no idea that the F22 ports were of such good design, if they are much better than the H22, how do they stack up to the B series ports?

 

are you gonna race and hope to compete and win stuff?

if yes, your gonna need more than a d series, and more than just an engine, and a complete car upgrade ( suspension, weight reduction etc etc) and be prepared to rip out your interior

if no then stick to the d series since you already have it, do a i/h/e and if you want to stick NA look into new cams pistons and rods, or get supercharger for FI and be just as fast as anyone else on the street.

ok so the bseries will yeild higher numbers anyway, so what? if your on the highway just stay behind him, let him waste HP eating away at the wind resistance while you sit back and relax in that little tunnel he just built for you
