vtec head on f22A1 block

[disturbance]

Alriight heres my problem i bought a F22B1 and installed it wired the vtec to the computer and the engine i got was messed up i think a bad rod or something..... so i used my non vtec block and swapped the head and everything fit fine but now engine feels like it has no power and vtec is not working. I will be checking the vtec selenoid tomarrow to see if its dirty but i have no idea whats happening.

so with that said has anyone ever done this and if so how did it work out?

ok so i just saw a thread on the f22b1 running like crap and not passing 4k i tried posting but it said i couldnt so going to do it here lol. so my car passes 4k but slowly and has no power after. got the engine from a 94-97 accord ex and also got the ecu so can anyone please help me here. i took out my F22a1 and right now its looking like a big mistake since i cant get the f22b1 to run right

The F22B1 is a serious downgrade from the F22A. Even when it works correctly.


Check your oil pressure and level. If your check engine light is on, find out why. Be sure all your VTEC wiring is correct. Most likely, losing power at 4000 is a result of that shitty VTEC system not working.

thanks bro i found out a little to late lol. so what im going to do is build the head on the side and the F22b1 block since they are the same probably put the bisi 12:1 pistons

i appreciate the help

jus so u knoe, the B1-B2's are better then ours, my boy has the F22b1 or b2 non vtec, an it kills my A1 with A6 manifold! an he only has like full exh. intake lil stupid stuff. get it runnin right an it will rip pritty good!

The B1 makes 145hp. The B2 makes 130.

The ports are extremely restrictive, the valve angle sucks, and the B1's VTEC system (which works on the intake side only) adds significant valvetrain mass.

So no, they are not better than the F22A. Your "boy" either has a healthier engine than you do, or you can't drive for shit. "jus so u knoe"

Well said deev!

And yeah, the VTEC on the B1 and B2 are for shit. Really it's closer in relation to the less often seen e-vtec that came in certain civic (hx?) models a while back. It did the same thing regualr vtec does, just at lower RPM and only to conserve feul, not add horsepower. Just because it says vtec doesn't make it good.

***EDIT***

Apparently the B2 has no VTEC. News to me.

The B2 doesn't have VTEC.

As for doing the "same thing"... no the F22B1's VTEC is considerably different from the VTEC systems in the H and B series engines.

its the same as the k20 on the ep3 they re shit
dont compare them to the regular k20 cuz they suck
both motors use vtec on one cam, so comparing them is worthless

to the op, whenever your swapping to non- vtec block to a vtec head
make sure you remove the oil jet from the oil feed in the block
it restricts oil pressure 30psi because non vtec heads dont need as much

make sure you get rid of all you CEL lights and check your physical timing
its really easy to be a degree off when swapping b1 head

overall, it will be slower then the stock a1/4/6 whatever you had. and it will not make as much power. I speak from experience.
