I think the h23 vtec is the best h swapp for the money right now . If you want to upgrade it later it already has the h23 crank with 55 mm main bearings ( so you dont have to worry about braking ) also comes with the newer style lma in the head so no noisy valve train noise . I recently got to cc one of these to see what the real compression was its 10.6 just like the h22 so if i have to guess same motor with bigger stroke probably puts down a few more ponies then the h22 also. If you wanted to do a nice cheap build later it comes with floating rist pin rods were h22 you have to buy eagle rods to run type s pistons because there floating pistons along with every other aftermarket piston out there. I mean if you was doing a all motor build that alone saves you 800 dollars because crower is the only company that sells rods for a h23 and there 800 bucks . H23 best bang for the buck if you ask me . f20b hell of a motor and depending on what you going to do another hell of a deal just realy no reason to buy a h22 anymore .
