Even this with their 2L/2.2L engines big turbo and moderate boost still make, IMO very little torque for what they are.

what is VERY impressive thought is that the car in the second vid uses a stock bottom end.
Im not saying that they are a bad engine, I just prefer the characteristics of a short rod turbo engines.
Compare them with like for like boost.
What happens with the YB is that its so shit at breathing that people pile more than 2 bar of boost down its neck in a desperate attempt to get it to make power, which results in big midrange torque as a side effect and the thing STILL wont rev properly.
On the honda turbos you have a much flatter and more useable torque curve that allows you to make the power much more linearly and further up the rev range.
Thats a PLUS point on the honda not a bad point.
2 engines
both 1 bar of boost
both 2 litres
1 makes 350lbft and 500bhp
1 makes 300lbft and 260bhp
which would you prefer?
cause thats typical figures for a YB and a F20C from what I have seen
