Owning both a B16A and a B/T 20V, the B/T 20V is a very interesting engine to me. The spread of torque honestly feels alot better than the B16A..... and this is only with adjustment in inlet cam timming. Granted if you are planning to mod it extensively internally.... you are probably best to get a 16V and go to town on it. Aftermarket support for the 20V has never been there compared to the 16V 4A-G, and to an even greater extent the B16A.
I have always wondered though how the 20V would have felt if it had lift from VVTL-i. Still.... Yamaha did a very good job of it, F1 5 valve technology gimmics aside.
In saying that I am a big fan of the B16B... and something which may freak alot of you out.... power output is not the reason why I like it. The R:S ratio of the B16B is of great significance to an engine that is to be operating in sustained high RPM operation.
