Guess we just need to wait for HomemadeWRX or someone who can get their hands on the engine to tell us the detailed specs...the short rods bother me quite a bit, the Honda motors are also 86x86 but they have much longer rods, and have those nifty dual cam profiles, whereas the FA20 will lose more and more bottom end as you push the power up (mild hybrid system?
).
For outright power things aren't looking so good, but at least we have an updated efficient combustion chamber design.
