ajustable cam gear
by adjusting a cam gear on a stock cam you CAN add horsepower to your motor at low mid rpm....but at expense of high rpm power.
To explain in simple words, pretend you are looking at your engines power graph......by advancing your timing you would shift that whole power curve to the left, i.e. you would reach your highest hp at lower rpm, but that means that at very high rpm, like 5500-6200 rpm the power would drop off....but with aftermarked cam, you would need to adjust the gear to get the most out of your setup, since most aftermarket cams, even if advanced, won't lose power in high rpm and you can still gain more low/mid power/torque while keeping your high rpms potent

no one makes off the shelf cams for the F22......all are either customs (like bisimoto's), or are regrinds of the stock cam
if you change timing too much, you can sometimes encounter detonation, and even advancing it alot, even with a regrind, isnt gonna net a whole mess of power. esentially, to make more power, you have to increase the pressure/volume of the fuel/air in the combustion chamber....you not gonna see 25 whp from a cam regrind...no without some more work on the intake side of things

with the right profile the cam is good for 15whp....pnp intake mani, tb, head, and you can expect close to 30-35whp from the whole setup....
price? cams anywere from 300-600$....pnp can range from 1000-1500

Watch out. If you have an adjustable cam gear with too few bolts to lock it in place, or if you overtorque any of the bolts or the timing belt is too tight it could crack open like THIS:

This is the second thread on a ruined cam gear i've seen in the last week.

No, you just need to either swap in an H or leave it alone, the car is fine the way it is, that's the point

There is a lot to weigh with what you are looking at.
You can do the simple swap of a H22 motor. With everything done and said you are loooking near $3000-$4000 for all. Decent HP gain and better options for a build.
As for the stock F23 motor, there are many options, but costly ones. I have seen several posts to swapping a H22 head on a F23. I have seen turboing a F23 gain a decent amount, WHP @ 210-225(depends if motor is stock or some work). As for all the P&P on the motor, not sure yet. I am getting ready to have mine done, both head and intake manifold. I will let you know of costs and hp gain.
Good luck on your decision. Lots of options, but it all comes down to the $.

Youre right, he can spend lots of money instead of just keeping the car, swapping it or turbocharging it. The risks and gains on a cam and cam gear on a stock Accord outweigh the cost.
I looked online. For H22, there are camshafts available that will give you 10+ hp that are made specifically for the H from new cores, not reground stock cams. If you really want to build an all motor setup, i'd consider the H series, since it's a proven power plant and you wont have the hassle of custom fabbing everything. Reground cams can see a lot more stress and are prone to breaking, especially if they're ground improperly. I'm just saying you dont need a new car, you can keep yours and rethink your options. The car isnt a problem.
FYI --- Keep in mind that if you do anything to a H22, make sure you sleeve the block. I have heard and seen many stories of people putting new cams and other internals and blowing the motor.
what risks are involved with getting a regrind cam and a cam gear. only reason the ones you linked to broke were because of a defective design, not cuz they were over tqed or cuz they had too few bolts
i have customers who daily drive with the old school aem 3 bolt design and they have been fine for countless years

so we need to sleeve our blocks so that we can run cams in the h22s?

Not so much just cams. If you start to do any big thing like changing pistons, rods, etc.. Then yes, the block needs to be sleeved. It should be okay running cams to a point.

that is often more work than just swapping in the whole H block

That doesnt work. I wouldnt spend the money, H22's are getting easier to find, i'd just get a whole engine and tranny.

So how much money am I looking to spend to do the swap eng/tany and is it hard // does it realy run that much better than the sohc motor/ cuz the car need a lot of work/rac/balljoints/fender /hood /bumpers /bondo im thinking that it would be more woth it to buy somthing newer ..
hmotorsonline sells engine, tranny computer, the whole thing, for an H22 for 1950-3600 depending on year and type (type S has more hp and torque) plus shipping. With a lighter 91 accord, it will do a lot. You could either turbo it or swap, but i'd rather swap for durability.
