Honda's biggest engine?
 

what is Honda's biggest engine in terms of displacement? past or present. :)

3.2l ?

3.5 from the Rl and pilot i think

I think its the (I think its J-series) J35 in the pilot, RL and MDX

well there is a V12 that Ive got a picture of....... not sure if it was just for display, racing or what.....

Megen F1

Whats the details on that engine ( Megan F1) cc's, horsepower, torque, compression ratio etc.....

Do you mean Mugen F1? If so, that's a V10 and under 4.0L not real sure. Horsepower is somewhere near 650-700, redline set probably at 17,000RPM. The reason I'm not sure of the specs is that they are highly guarded. It's a Formula 1 engine, not even made by honda.

Honda RA002E
3000cc v10...
redline "In excess of 17,000 rpm"
