Did I mention the older B series are not related in any way to the newer B series? The last of the Prelude B series motors had a name changed and was called the H23. That was essentially the final version of the Prelude B series. The B series motors in the Integras and such are completely different. The easy way to tell, Prelude B sereis motors are mounted at an angle... As for the B18C and B18B... the B18B had a slightly taller stroke... but like you said, it wasn't much. I don't even think it was 50cc total... probably closer to 20-30cc. I forget exactly which is what. My point is, the motors are essentially identical. The B18B makes a better torque band, but that's only because it was designed to do so without VTEC. That doesn't mean Hondas *need* Vtec to make power, all it says is that they altered their designed to best utilize VTEC. Same deal with Toyota... the 1ZZFE was designed differently with a smaller bore and larger stroke than a 2ZZGE. Take for example, the K20A3 that came in the 2002+ Civic SI. It's a good motor, and although it claims to have VTEC, it has a different type of VTEC. This is an econo designed motor, similar to the old HX D15's back in the day. The engine runs on 3 valves per cyclinder (actually has 4) until its "VTEC" kicks in in the low rpms (~2000), which open up the 4th valve. This is done so chamber velocity is at its highest, making the best amount of torque. The base model RSX had the same motor, but they also incorporated intake manifold butterflys, similar to Toyota's TVIS system. These things together, do make for an engine that has very good low-end to mid-ranged response, and they do not utilize the traditional high lift multiple cam lobe VTEC. Honda does make good non-VTEC motors... but if they sell a lot of VTEC units... who cares? As for the old 3rd gen B20/21 vs the 5SFE... unfortunately, I'll disagree simply because the B20/21 can deliver more torque higher in the rpm band. True Dual Overhead Cams is the reason. The 5SFE makes torque, so you immediately feel the torque even at low throttle, while the B20/21 are pretty opposite... starting out flat and finishing up strong. I don't know what you guys did to your B20/21's... but ours was a 14 second car and was only modestly modified. I'm not saying the 5SFE is a bad engine... it's just not designed to do what a lot of people are looking for it to do. I've been there, and done that. -------------------- "It's ok to be naked girl... I'm an artist!"
