A buddy of mine wants to do a simple motor replacement in his 91 LX , not trying to do the H22 swap . He wants to do a F22B1 VTEC or F22B DOHC , can't decide if he wants to go VTEC or DOHC . I also recommended that he looked into the H23A1 Non-VTEC . Any suggestions on what would be the best replacement motor ?

I'm not sure what's wrong with it , not sure he knows either but it's been running rough for a while and getting worse . And he wants a little more power but no H22 , H23 VTEC , or F20B power . Something that isn't gonna cost that much . I recommended the F22A6 with some bolt ons but he wants DOHC or VTEC

The F22B1 is a downgrade from the F22A. Cramped ports and poor valve angles. If he just wants 150hp and good fuel economy, it's fine... but if he wants to modify it, there's no use swapping to that motor. VTEC only works on the intake valves anyway.
The F22B DOHC is very nice, but doesn't really have all that much more to offer over the F22A. For the price of the F22B DOHC swap, an F22A can easily be modified to make even more power. Again, if 160hp is good enough, then the bone-stock F22B DOHC fits the bill quite well (as does the H23A1.) Both the F22B DOHC and H23A1 have their drawbacks... mainly, the F22B DOHC was never sold here, so any specific parts are not easy to find (like the timing belt.) The H23A1 has FRM sleeves, which are fantastic, but can result in oil consumption as the motor wears out, and they're more difficult to resurface (many shops don't want to deal with FRM sleeves.)
Why doesn't he want an H22? Because "everyone else has one"?
That's about as smart as saying "I'll eat a lump of crap, because everyone else is eating cheeseburgers!"

if he like sound... go with vtec...
personally if i change my engine i will go with a vtec 
this depend of what he want... every swap is different, everybody has different idea...

The F22B1 really doesn't even make a sound. The VTEC system in the F22B1 is very different from the VTEC found in the H22, H23A, F20B, B18, or B16 engines.

Your swap was just a mess, though! It really isn't usually that complicated! Honestly, just about ANY swap can come with just as many problems...

And it would've been much worse if it wasn't for this site !
But I just showed him this thread and he's wanting to go with the H23A1 but it seems like the F22B DOHC is more commonly found for sale

I'd go with an h23a1 over an f22b dohc
h23a1 is a USDM motor and parts are easy to get for it.Comment

Yeah that's what he's gonna search around for . Is that swap pretty much a Direct drop in with F series tranny ?Comment
-
Pretty much
You will need to wire a knock sensor and extend the wire for the oil pressure switch as its lower on the engine block
besides that its pretty much the same.Comment
