I got a 97 accord with an f22b1 in it. I want to boost my car with a goal of 350 whp. Everybody has told me that the f22b1 is better to boost than the h23 because its got stronger walls so the motor's holding capabilities are a lot higher than the h23, Ok. Now, i really want to do a swap to my accord as i want to run a dual cam vtec motor in it and i just found an F-series that seems to be able to get the job done.

I found an f20b in a website. My question is: How good is this motor for boost ? are the walls as strong as the f22b1 or is it the same as the h23 ?

 

DOHC vtec f20b? Iron block, so good for boost, but high compression, so a really good tune is needed. But it would be very repsonsive at low boost. You could get custom pistons made for around $600, which would lower the compression quite a bit, and might be a little more turbo friendly. What are your power goals and spending limits?

 

F20B = H22A for the most part, just think of it like that

 

f20b = h22 ok, but is the f20b walls as thin as the h22 one's ? I dont mind spending 4000 for properly boostin the f20b. i just want it to get done right.

 

It's a destroked H22, so I'm wagering they didn't change anything with it really haha. If you're planning on boosting I would stick with the F22B1 and 350whp is attainable with it.

 

so the f20B walls arent FRM?

 

Apparently they aren't, I'll have to correct myself, I was under the impression it was almost identical to the H22A block.

*edit* That's after doing some more searching around on the interwebz, though there seems to be quite a bit of confusion on the subject. Some say they are others say they aren't.

 

the block is IRON. just like stock f22a single cam's.

 

i havent seen a boosted f20b. not gonna lie. If i was going boost i'd probably go f22b1. If your going NA i'd go f20b.

 

ther block is aluminum, the sleeves are too, the LINERS are Iron.


Bai

 

 

so the f20b not good for boost. Damn, i guess i'll stick to the f22b1 then THanks a lot guys.
