It shouldn't be a problem. Just swap everything over, including the coolant pipe. You might have a problem with the driver side mount, should be able to swap them over.

so is that all i would have to do or what..has anyone done this..is there any thing against it or what?

that really didnt help my im looking to just use the f22b1 block thats all from that motor...i couldnt find anything when i searched about this engine combo.

My friend has this combo on his CD5 and it works fine. and he pulls so hard.....we've raced and he always win...but he has a 5 speed.

swap the head on, change the coolant pipe, and use an F22aX timing belt. I only remember using the F22aX mount on the drivers side that has the rubber in it. I'm almost positive the mount brackect on the block was the same. I was running this same setup before

[brand0n327]

okay is the compression between the two blocks the same or what? i would guess not but you never know with a honda

[whitecoupe91]

I'm pretty sure it was the same, 8.8to1

[whitecoupe91]

if you look in the performance tech section and read the sticky that says H/F engine demensions it shows almost the same exact numbers for the F22a and the F22B block. the the obd2 blocks didn't have the timing light hole under the water neck. You do the timing light off of the crank pulley and the timing belt cover.

there isnt a DIY thread for this swap is there? i hope so but the keywords i put in never bring anything useful up. i hope i dont start doing this swap and run into problem after problem.

[whitecoupe91]

its pretty much a straight forward swap, replacing an engine and doing a headgasket all at once lol

[Mick92]

The f22b1 head is completely different than the f22a1 head. But the block is the same from what Ive found. There is a difference in the driverside mount - engine side. You need to use the a1 but there is a portion of it which is very close to the timing belt and will cause your timing belt to slap against it if you dont grind it back I would say 3-4 mm.

Trust me it slaps, i know i made mine do it lol! doesnt really matter for me as my head had broken exhaust valves and I have to remove all of it again.

As said before im pretty sure its a direct swap, as long as you swap the coolent pipe too. BUT do note the head gaskets are different!! so make sure you can figure out which one works best...

[whitecoupe91]

use the head gasket for the head you are using and it will be fine. I used the head gasket for my F22aX head and it was fine.
