Some misinformation going on here, and it seems to me like no person who answered has ever actually done the swap before. I'll try to clear some stuff up for you, since I actually have done the H22A swap before.
1)With both the EG & EK swap, you'll have to cut off the transmission side mount bracket off the frame. You just replace it with the one Hasport gives you (assuming you're going with Hasport mounts). You also need to cut 2 holes in the interior of the car, for the shifter and shifter cables.
2)The H22A does sit lower, and it you lower the car too much, you can definitely scrape it, especially on steep inclined driveways & speed bumps. However, the bigger problem with lowering it too much is the axles. If you lower the car 2" or lower (than stock) you run the risk of snapping axles. I've personally seen this on my friends car.
3)You don't HAVE to get a bigger brake set, but you should definitely upgrade your existing brakes. Brembo blanks & some good pads will be enough, as well as fairly cheap. Stainless steel brake lines would also be a good idea. As for Suspension, it depends on what you go with. Just don't go with any cheap E-bay no name/knock-off stuff. Progress Technology makes springs specifically made for the H-series swap, they aren't too expensive. The "problem" people often refer to with the H/F-series swaps is the understeer. Contrary to when most people say, it has nothing to do with the weight of the engine, it's the way the engine is tilted that is the problem. And honestly, my friend's turbo'd H22A EG (Progress H-series Springs, Energy Suspension bushings kit, & KYB AGX adjustable shocks) has less understeer than my Stock '94 CX EG (no powersteering).
4)The price of the swaps are around the same, unless you get a usdm H22A1 for cheaper. But it should cost anywhere from $4,000-$5,000 for everything you need. This is just a rough estimate, and if you shop around you can do either swap for cheaper. As for which one would be initially better, it'd be a pretty close call. I honestly wouldn't even dare to guess.
5)Both engines, in a way, both have greater potential. The H22A's head come unported & polishes, unlike the B18C5's mild P&P job. The H22A's intake manifold can be modified or replaced for a much better one, the B18C5 already flows very well, especially for a daily driver. On the other hand, there are far more aftermarket parts available for the B-series engines vs the H/F-series. So with the H22A, you're limited to what is available for you.
6)As long as they are taken care of and you do regular maintenance, both engines will last just as long as the other. People claim that the H22A is weaker, but that's just a bunch of bs that has been spread around the internet. the H22A sleeves alone are far stronger than the B-series or D-series.

I AM A CERTIFIED TECH AT HONDA
H22
I HAVE DONE THIS SWAP PERSONALLY MANY TIMES (ITS A B**** AND VERY TIME CONSUMING). IF YOU ARE GOOD AT WELDING IT IS A PLUS (MOTOR MOUNTS) YOU DO HAVE TO SHAVE SOME OF THE FRAMEREGARDLESS. IF YOU BUY A BOLT ON MOUNT KIT BE VERY CAUTIOUS OF YOUR RIDE HEIGHT. YOU CAN DESTROY YOUR AXLES AND HEADERS IN A HEARTBEAT. IF YOU GET A CUSTOM WELD ON MOUNT KIT YOU WONT HAVE THAT PROBLEM AS LONG AS YOU POSITION IT RIGHT AND HAVE GOOD CLEARANCE OF YOUR AXLES. AS FAR AS SUSPENSION YOU CAN USE A LOWERING KIT AND BRAKES JUST USE THE H22 BRAKE ASSEMBLY WITH 16" OR 17" WHEELS ON THE FRONT AND KEEP THE REAR THE SAME. THIS WOULD COST YOU ABOUT 3-4 THOUSAND FOR ALL PARTS (ENGINE TRANS ECU AXLES CALIPER ROTOR PADS SHIFT LINKAGE HEADER MOTOR MOUNTS RIMS TIRES)
PERSONALLY I GO WITH A B20 (HONDA CRV) AND DO A VTEC CONVERSION. IT USES A B16 HEAD AND PARTS ARE CHEAP COST IS ABOUT 2600 IF YOU SHOP RIGHT (ENGINE TRANS (LSD) MOTOR MOUNT THROTTLE BODY CABLE AXLE ECU SHIFT LINKAGE HEADER VTEC SOLENOID SPOOL VALVE VTEC OIL PRESSURE SWITCH )
HONDAS ARE RELIABLE ALL AROUND IF YOURE GONNA DRAG IT BETTER HAVE A SECOND CAR READY BECAUSE YOU KNOW THE SAYING "MAKE IT TO BREAK IT"

Which would be better? B18c5 vs h22? - Yahoo! Answers
yes correct, same for the civic, but read the yahoo answers i have posted, the guy mentions to get stiffer suspension and/or mount the engine higher than the stock.
