that makes no sense. the f22a is an 85mm steel bore you could just use that, the F20B block provides no other benefits than any other 85mm steel bore, other than being setup for a DOHC VTEC head passage-wise

But as prelittlelude has shown you can do that for an f22a anyway.

The reason why people don't all use the F20b block is because it's rare, expensive and only 85mm at the end of the day.

tru i hear that i was just wondering if you can use the 2.2 rods n crank in the 2.0 block to give it sum more displacement like im doing with my h23 rods n crank in my h22

cheaper to sleeve any F or H motor than to get an F20B and swap internals. If you buy an F20 and resleeve it to 89mm you will be back up to 2.2l. But here is my question WHY? too much money?

I think you need to understandf the relationship between bore, stroke and displacement

F20B Block = 85mm bore, 88mm stroke = 1997cc
H23 block = 87mm bore, 95mm stroke = 2356cc
H22 Block = 87mm bore, 90.7mm stroke = 2157 cc

F20B has a smaller bore...if you put h23/f22 crank in it, it would have less displacement than an h22 with h23/f22 crank and rods. ON top of that you just paid an assload more fr an f20b block. on the bright side you don't have to sleeve to run forged pistons, but again you could hav done that with a regular f22 block and had the same results =2.2L

im just tryn to understand this motor compared to the H series cause if i pick up another shell thinking of doin this swap because u dont have to sleeve it, you can use forged internals and its DOHC vtec as well....

i was just thinking about what type of budget build u can do using oem parts

you can't bore out an 85mm block any more than 85.5mm that's why Honda created FRM sleeves in the first place it's what allowed Honda to get 2mm in bore off the same crank spacing of F-series motors creating the H-series at 87, and get 3mm more on the 97 NSX to 93mm

exactly the f20b is a sick motor to begin with, i know so many people that would kill for the crank and rods that are in that motor, not only does it have iron sleeves and the capacity to rev a bit higher than the h22 but it is setup to accept a dohc vtec head from the factory. the motor is just plain sick

if you want a 95mm storker just start with a f22X block
