engines??

I've been around a lot of engines, and I still get a little lost sometimes. When you think you know them, you start getting confused when they throw in JDM codes, which are different, but are almost the same. Take b series engines for example. I have a del sol vtec, which comes with a b16a3 160hp. This engine is a dohc (dual over head cam) and it has vtec. But we swapped it to a JDM del sol engine, which is a b16a 170hp, with no 3 behind it. The difference is hp and torque. Then, the civic si has the b16a2 160, which is almost the same thing also. A jdm civic type r engine code is b16b 185hp, which is a different, more hp engine. Then you have the integras, which are b18c - JDM integra SiR-G 180hp, b18c1 - USDM GSR 170hp, and b18c5, which is the type r integra 195hp. There is the rare b18c6/7 which is a jdm 96+ integra type r 200hp. There are LOTS more, I just don't have time right now. I'll get back to ya.
