next week or so i plan on pickn up an f22b1, i plan making it n/a cuz i got love for the sohc. what would you guys recomend for the bottom end? i think pistons im g2 do prolly 11:1, but what about rods? are the stockers in it strong enough for around 200 hp? what about the valve springs in the head? should i get some slightly stronger than stock?

any info would be good. pZ

 

are you planning on staying single cam?

 

The rods are probably good for NA, especially if you get some light pistons. There are a few good SOHC threads on here. It's a bit harder to find performance parts for them, but they're relatively cheap to tinker with. Good luck.

 

yes i plan staying single cam, thats the reason 4 doing the f22.

anybody else?

 

If your looking to get a set of forged pistons and you want to keep your stock rods make sure the pistons use press fit wrist pins. If they only use floating wrist pins your going to have to get a set of aftermarket rods with busings in them. $500-700 bones for most of the F22/H23 bushed rods.

I've looked around to see if anyone has put bushings into the stock F22/H23 rods. I haven't been able to find any information yet. I don't have mine out of my block yet to actually measure them. If there isn't enough material there to bore and press some bushings in them then I'll be looking for some rods. The pistons I'm looking at only come in a floating wrist pin configuration.

hmm ok so i need to look for pressed fit pistons, not floating wrist pins cuz i dont want 2 replace the rods if i dont needs 2.

what about ecu wise? if i use the p28 can i remove all of the emissions stuff?

 

You will need to get the P28 chipped and tuned for your F22 first. The short answer is yes you can get rid of the emissions stuff..... Before I took my 96 F22B2 off the street I was running it on a chipped & street tuned P72 w/VTEC disabled and all the emissions stuff turned off. Ran pretty good for the short time I had it on the road.

 

search bisimoto ......

 

Did bisi use an F22B1? Theres a couple posts on the internet discussing the F22B1's head design and how the flow pretty much sucks on it.. you might want to check that out. I think the head is pretty vital in the quest to making power.

 

thats kind of what i have been hearing. somebody said get an f22ax head? what kind of f series head is best?

 

F22A1 heads have pretty good flow actually, and has really good potential. let me see if i can find these air bench flow charts on the F22A vs the F22B1. You could also try going with an H23A DOHC head or an F22B DOHC head if you want.

 

i couldnt find the flowbench tests just yet, but heres some pics of the port design on the F22B1 vs the F22A1 on the intake side



You can kinda of see whats going on here

 

the f22a1 head flows alot better? would buying valvetrain and cams be similar for buyin the b1 head?

 

what would be the best intake mani 2 get?

 

You will need to swap out for the F22ax head to make any N/A power. These heads flow as well as the B series heads. The F22bx and the F23 heads flow horrible.

 

are the f22a1 head vtec? also are they obd1?

they are obd1 but they are not vtec. The best manifold would be the F22A6 manifold or the H23 manifold (if you get the F22Ax)

 

There was only one year of OBD-II F22ax head and that was in the 96 base modle prelude. But they are all non-vtec. You don't need it. You'll make more power with out it then with it in the F motors.

 

Here's some information regarding the headflow on the F22A1 vs the F22B2 (non vtec), im sure it will state the obvious.

My F22a head flow numbers look better . These are the final#'s compared to the one's I posted earlier.

intake exhaust
.050 45 41
.100 87 83
.150 127 121
.200 163 150
.250 191 172
.300 218 186
.350 241 198
.400 261 211
.450 276 215
.500 288 218
.550 296 221

As you can see the F22a will out flow far and above ANY F22b or F23 head. Those numbers are in B-series relm.

damn! i think those numbers i posted where with a mild p&p.. but jeeeze.. creeping up on 300cfm are we? how much power is your F22Ax making and what have you done to the bottom end to make use of this extra air?

 

theres more to the head than CFM numbers. but who ported it? any numbers?

 

The motors being build right know. The head is done and I'm waiting on the rods to come from Pauter to get the block back. The bottom is a worked over F23 bored out to 87mm using TSX pistons. I making use of some custom parts from Bisimoto. The motor slated to make power up to around 8000rpm and still be daily driven with out loosing to much bottom end torque.

Once its finally done and tuned I will post a build thread. Shooting for around 200HP or more.

 

[Off Topic]
Could I make a suggestion turbowa. After reading your last big build thread and noticing that it got stolen. I would maybe keep your next High Priced generic build off the forums. If there is nothing custom about your car other than expensive internals your just putting out an add for someone to snag it, tear it down, and sell the parts. But that's just $0.20.

Good luck building a motor that will make use of that 296CFM head

The car that your talking about had WAY to much money involved in it and went through so many stages that every body in there brother knew about it in ohio.

I will never invest that much money again in a car. Crist for the money I had in that car I could have bought a house. (No joke). Nobody where I'm at know now the car except for the tuner. Even the shop that I get some parts from localy has never seen the car nor have they ever met me, I send someone else to pickup the parts and pay over the phone. Once I post the build thread There will still be no pic's of the body of the car. And for the most part this build is using mainly stock honda parts except for ARP studs and the rods. for the block.

I learned my lesson last time. I still want to help out those that don't know much about these motors. There aren't to many of use out there.
