well i dont know anything about cars but i got lots of friends that do, but i was wondering whats the ups and downs of having this motor? is it better than the h22a?

It's more unique. It revs higher. It's roughly the same price.
Those are the good things.

The bad things are:
It has less torque. It has a peakier powerband, higher in the RPM range. It's OBD2, which involves more work when swapping compared to an OBD1 H22A. The proper ECU is OBD2, and the standard practice is to convert the engine to OBD1 for use in the CB7. Therefore, you cannot use the stock ECU. Your options are an H22's P13, which will run rich, or a modified and tuned P28 or P72 ECU... which will cost a good amount of money to do correctly. Finally, any parts that aren't shared with the H22 will have to be sourced from Japan, since we never had that engine here. The H22 was sold here, so we have access to parts.

no lie ive heard the same things about the f20b.. i was SOOOOO focused on getting it but after research ill go h.. the torque is madd low n the only way ittl produce is with the f20 tranny. BUT. a f20 tranny on the f22 or the h22 is a major plus cuz ittl accelerate alot quicker.

Honestly, from what F20B owners have said, the actual difference in performance is minor.

I mean, the H22 isn't all that torquey itself!

sweet man . i'm building a f20b blue top for my cb now. but i got to agree with dee. thats the same thing i heard about them as well.they should be a little lighter in weight tho..good luck man i hope to see mine in soon.
