I have a 92 prelude s non-vtec how would i reach 175 whp?

 

h23vtec swap.
good bolt ons...done.

 

 

I think he only has one cam.

 

 

I get the impression the F22A head is actually better than the H23. I could be mistaken, of course.

 

Do an H23A VTEC or JDM H22A swap and you should be set and will be a good start for your goal.

 

It's better to run stock motor from factory that can put out the #'s he wants then to crack open his head and put in cams, tune, and do compression. Thats almost a fully rebuilt motor.
What compression are you running to get 200whp?
If I remember correctly, your motor is not a stock h23 which puts out 160crank but he wants 175whp. He's gonna need a 40whp gain from that stock motor and thats not gonna happen without some big mods and tuning. 175whp from an h23 will cost at least $2000 depending on whos doing the work but you can get an h22 for less then that.

 

why swap it? it'd be a waste of time and money.

the F22 has more potential than people let on. people are attracted to big oem numbers and completely disregard potential power. the F22 cyl head actually does flow better than the Hseries heads. the H22 in stock form IS a very well balanced motor. i will give it that. but as soon as you crack em apart to start moddin internally its a ticking time bomb. not saying F22s are better but its been proven time and time again with a few mods the F22 can be as good as, and in many cases BETTER than an H22A. fawk all these H series nut swingers. your F22 is plenty to start modding on.

 

F22s can be great. If you replace pretty much single part on them, and just work with the stock crank, block, and re-done head. Pretty much everything on that motor sucks in stock form.

H22s are dirt cheap, you can use more OE parts on it, you'll get something that is probably newer (than a '92 F22), with VTEC, and if push comes to shove you can make about the same power. For the average person it's a way better path to go.

 

I agree with Blue Lude.....You will be much happier and thank us all later if you swap a fresh jdm h22a or go with a f20b or h23a vtec and start from there....

 

Waste of money? You can get an H22 for what 900? That's 160WHP right there assuming it's healthy. A GOOD header, intake, exhaust and a good tune is all you need at that point. Almost anything else would put you over 175.

How much would have to go into a motor that starts 75-50 HP less? At 175 an F22 would be a race engine. Lumpy idle, all power up top, ect. Same **** you have to go through from D-series people trying to prove the merits over the B-series.

Anyway, I'm not a "nutswinger" of the H. I took out a perfectly fine one for the F20B.

 

Shii... My JDM H22A with Skunk2 valvetrain and Pro2 cams with a good tune put out 200 to the wheel and 156wtq. If the OP went with my route, he'd be way over what he is asking and like mentioned above, they're cheap as f*ck.

 

I'd like to see more 170whp F22/23's, but for $1300 I swapped an H23VTEC into my daily driver and got 175 whp and 152 ft/lbs with just a header.

 

The F is not like the D. The F can make comparable power to the H, while the D will never be as good as the B. Without VTEC though it's going to be worse in a street motor.

The F20B is just giving up displacement and valve size on the H22 for no good reason.

 

I have to agree with Pirate here, if op only wants to hit 175whp there is other alternatives out there than new h22 swap.

And yes if you got single cam motor, than you want Bisi.

 

I'd sell the S and buy a H22A then tune that.

Better bang for your buck unless you have thousands to spend.

 

The H22 is better for the money. Unless you have the time, money and skill level to tear apart your F22 to make it what a H22 is out of the box. Waste of time, IMO. The stock H22 will be more reliable, be cheaper and probably better on gas than a cammed out F22.

 

I would like to see an NA F22 in a prelude running 12's....

You are building an F22 to get to H22 power levels...waste of time. you need 50-60hp gain from an f22 to compare to a stock h22. I would say that will cost more then $1000 which will be able to buy a h22. Then you can sell the f22 to recover some of the costs too.

 

If an H can do it I don't see why an F can't. You'd just have to live with the crappy low end of a big cam in a non VTEC motor.

In terms of bottom end the motors offer about the same potential, and the head on the F22 is pretty good as well with some TLC. It's not like a lot of non VTEC motors which tend to suck.

 

anything can be done with money but the drivability on the F will be **** compared to the H...
ANyways, OP, do what you want. Some people suggest building an f22 and others suggest the h22.
What do you want?

 

I had a F when I bought the car it went then I bought an H...they have the same old mods on them but after having both I would NEVER go back F...I'd save my money and get an H

I don't see why people put so much into the F just to start makin H numbers when they could get the H with the money that they were gunna spend...sell the F and put some work into the H and your set.

 

ya man ur better off with an h cheap and you'll be were u want to be at with horespower just motor add some mods I/h/E and you'll be in the 180s and plus ludes are ment to have a h in them haha come on

 

are there any all motor H22's making 455whp like bisi's f22?

 

Without a doubt it is possible, but realistically what you are looking at is how much you want to spend.

As PirateMcFred pointed out, if you dont want to get your hands dirty, then doing an H swap maybe in order. In either event the thing I would recommend is to do it properly and to do it properly the first time.

If you choose to stick with this powerplant, spend the money on quality parts so you do not have to go back and spend more!
