or get a h23 or F22b JDM head for you A1 block. H22 heads will not fit 4th gen accord blocks, neither will th F23 heads without some work.
 
what do u mean by some work what will i have to do i was told a f23 would bolt up with no work help plz thanks
 
a sh*t load of wireing and work and cash... you could do a whole motor swap for that much, and for about the same price you can turbo what you got and have way more get up and go then another head, search around in other forums at this sight or at cb7tuner.com that f22a motor has a sh*t ton of potential. its got low compression and not having vtec doesnt mean you cant run with the big dogs, its a misconception. dont get me wrong, vtec is great... you just got a ton more options that'll leave some cash in ur pocket. please, search away....

idk who told you this but there wrong... if you just bolt it on theres nothing to tell the vtec to activate.... i mean you could and it would work but it be pointless...

You need an entire VTEC head, not just the solenoid, and then you'll also need to run wires from the head to the ECU in order for the VTEC to function. You can run the wires yourself or buy a pre-made harness...
 
so will an h22 head actually bolt on to a f22a blockk? i was wondering that myself i wanted to put an h22 head ont the f22a block in my preludebeside wiring and ecu will it bolt on?
 
o ok.. so im better off boosting the f22 huh... it has a 9 to 5 to 1 compression.
will i need different pistons? the whole motor has been rebuildt with forged rods and forges bolts. will it handle being boosted wiht thata high of comoresssion?
 
Try this first....F22a6 camshaft, H23 intake manifold, S2k throttle body, F22a4 header or aftermarket header. Exhaust and Intake. If its a five speed you can try either a H22 or H23 transmission, both have tighter gears than the accord. H22 being the tightest geared of the two. A Prelude ECU or accord Ex ECU can be used to run the IAB's in the intake manifold. That should be a good start for you.
 
Wow i cant follow that lol.

Either turbo it, or swap a whole new engine.

Is the S2000 throttle body a complete bolt-on to the H23 intake manifold?
