That seems like a cool idea, first things first I need to get the car and get a f22, then I think ill try to decide where to go in terms of power (boost stock head, boost h22 head etc)

GhostAccord

I don't think the difference in port geometry could be any more obvious. The F22A has straight through ports. The passage of the air fuel mixture into the combustion chamber is straight in. Then the exhaust gases exit the chamber and go straight out the exhaust port. Where as the F22B/F23A heads all have siamese ports. There is absolutely nothing straight about them.

F22A
Intake = 0-0-0-0
Exhaust = 0-0-0-0

F22B1/F23
Intake = 0-0-0-0
Exhaust = -0-00-0-

Sure the intake ports flow the same.... Considering they are all pretty much the same from 90-02 F22A* - F22B1-2 and F23A* That wouldn't take much. The F22A can flow just as well at low lift if you were to use a cam lobe profile like the F22B1-F23A* use. I'm still waiting for the SOHC VTEC guys to post up the intake to exhaust ratios that they are getting. Also to post and how well the exhaust flows as compared to the F22A. The F22B2 can be completely left out of this comparison as it has 2mm smaller exhaust valves than the rest of the F series heads.

Sure you can get an F22B1/F23A* to flow 300cfm on the intake side.... can you match the appropriate % of CFM on the exhaust? The F22A exhaust does very easily.

In saying this ether head would be good for most of the builds that will be used on the street. Most people building these SOHC VTEC engines are boosting them anyway... easy way out!


OP if you are planning on going boost...don't bother choosing an H head over an F series head. Not worth the headaches.

Zak325

I would like to go boost. Not right away but later on. I will keep that in mind to keep the F series head

Forgive my spelling errors and the like, I've already begun drinking for this weekend. I have to deal with my nieces and nephew over the next week, so this is how I cope. HA!

Let's just toss this out there: F22B2 sucks. Hands down. It's like the crappier incestual step cousin to the other F-series heads, like a "crappy P75 head that's been sitting at the bottom of a lake for 40 years" bad. They flow like garbage, and although I'd like to try to point out the smaller valves could actually benefit torque production, the casting itself is just crap. Utter crap. If you have a 94-97 LX like me, throw it away the first chance you get, which is my plan.


Please, allow me to retort. I was at work, that was just pretty quick. I know all about the port spacing type thing, no confusion there, I was more talking about the angle of the port floors, valve angle, shape, etc. I still think the F22A heads may be superior in this regard, but I'd like see a cutaway of the two head types just to confirm. Even though the SOHC VTEC heads have goofy exhaust ports, flowbench test STILL confirm that they're pretty freakin' good- for a stock head. That all goes out the window with porting, and if you're going to port, might as well go all out, and that's where the F22A heads shine. They're really not that great in stock form, or even with mild port jobs. That's the entire point I'm trying to make, for 90% of the applications out there, the SOHC VTEC heads can and WILL out perform the F22A heads. Unless you're an experienced porter, most of the time, you have a better chance ******* things up with a carbide bit than not. Leave it to the professionals, which is expensive. Not only that, you DON'T want your intake and exhaust flow values to match, it'd totally **** up everything that has to do with efficient combustion and rofl

I May be a little intoxicated to understand what you're trying to say about the F22A* heads being able to match or better the SOHC VTEC heads at lower lift values. Wouldn't they not only need massive porting, but also material added and even more reshaping to match those values? Isn't that pretty cost ineffective?

I could go on and on about the specifics of what/where the SOHC VTEC heads are actually a wiser choice for the application, but it's all entirely dependent on just that: the application. For a street car with a fairly mild cam and a modest budget, it's really actually pretty hard to match the performance of the SOHC VTEC heads.

We can get a lot more advanced. I neither have the time(beer to drink), patience(beer to drink), money(beer must be bought), or equipment(spent money on beer) to test such theories though.

With this regard I'm still keeping my head, it's flowing good so far and I see no reason to stop now.

Zak325

So for making a daily with a little performance on the side, would getting a f22b1 the vtec one that comes stock in this car be a good choice

DeadlockRiff

In short, I would definitely say yes.

Zak325

I did some research on the f22b1 and I've read that the vtec is more of an eco vtec rather than a VTEC JUST KICKED IN YO! Is there any way to adjust that and get it to more of a vtec just kicked in yo feeling?

Zak325

thought you guys might enjoy this. hahah http://scranton.craigslist.org/cto/3877768970.html

DeadlockRiff

I want to throw a brick at it. He ruined a possibly beautiful wagon. At least in my eyes he did.

Yes, just slap on the front end of a car that has body lines that are lightyears different that the current chassis.

chrisnick

Cam and tune.

Zak325

The best part is the fact that he got it to fit perfectly. It seems like cams are very important when it comes to the performance of the f22. What would you guys recommend for a cam

Zak325

Now correct me if I'm wrong, because I'm just pretty much guessing here but those the trumpet looking throttle bodies. Their job is to let in air? And if that's true then would you still need an airbox with an intake? Is any of that right?

GhostAccord

If you are talking about individual throttle bodies per cylinder.


You can run them ether with an air box or with individual filters. With individual filters you would remove the larger open trumpets and run a set of 4 individual air filters with built in velocity stacks. Same thing you would find on most aftermarket 4 cylinder bike filters. I will be running an air box over the ones shown above.

Zak325

Yea those are cool. If I were to run an airbox or a cold air intake(if that's possible) would it basically plug into the individual trumpets or would it plug into the general intake manifold, leaving the trumpets open?

GhostAccord

Filters would plug into the throttles. An air box would have to be built around the throttles. Then a cold air intake could be added to feed the air box.

I am currently working on a set of home made individual throttles with an air box and CAI setup. This setup is being built using a set of 01 GSXR-1000 throttle bodies and modified air box.

Here are the 4 throttle bodies with the bottom half of the air box and trumpets fitted. The air box is completely sealed around the top of the throttle bodies.



I then added a 3" inlet pipe, as seen on the bottom. It has an opening on the right side. This opening will allow me to connect to a CAI and filter.

Once the top of the air box is added you can see how it closes and creates an intake plenum (air box) that completely surrounds the throttles and velocity stacks.

This allows the CAI to be the only source of air for the throttles.

Here are three setups, (from left to right)
1. has a sealed plenum over the throttles and trumpets, that could be connected to a cold air intake.
2. has individual velocity stack filters over the trumpets
3. has open trumpets

Zak325

Wow that's cool. Nice job on that. How much performance do you expect that to give you

NZXTInerTia

Mentions ITB's. GhostAccord storms in with his knowledge. Haha!

As far as cam's go the Bisimoto cams for the F series motors have proven to show fairly impressive power increases. I will be installing either a 2.0 or 2.3 cam in my boosted F series Accord.

GhostAccord

lol.....Any time the word individual comes up in conjunction with the word throttles. My curiosity always peeks! If I can share what little I know about something, I will. I don't know much about boost aside from what I have read about it. So I tend to stay out of those conversations.

DDTECH, Web and Delta also have good grinds for the F series. Really depends on what you want from your camshaft. Prices are all reasonably close as well.

DDTECH Camshafts
Web Cam Inc.
Delta Camshafts

I have been in conversation with Derek @ DDTECH Camshafts just recently. After our conversation I have chosen to have him machine my next custom camshaft. Very knowledgeable, informative and great customer service!

chrisnick

Lol, I've also been following him too! I'll also be calling him in a couple months.

Zak325

offtopic here but wow 350$

Zak325

more offtopic. I'm gettin bored waitin to get this accord so I figured I'd show my other ride. Anyone like this kinda stuff around here?

NZXTInerTia

Yep, CRF50 140/160 mod (motor built buy yours truly), modified BBR frame, Pirahna swinger, BBR SP-5 forks, etc. You could ride the thing without a front wheel. lol I miss it, but I love my Accord more. I can actually take that places!

Zak325

Sweet bike. I always wanted a little 50. These 250s fly though

Zak325

Now let's say I buy an full f22 from eBay. What will I basically have to plug in. Harnesses, tranny cables, throttle cables, radiator hoses, fuel lines, what else ?
