my B20VTEC puts out 160+ and it holds 7 NSW hillclimb championship class records and has over 45'000km on the engine (that was built in my garage)

it is a daily driver and gets revved to 8600 often...

i guess it is not 200'000km *just yet*, but not really sure why you would expect Honda engineering not to last very long?

the current 12.5:1 engine manages around 8.5l/100km, ive had it down to 7.6L/100 on one trip to CBR.

the two previous 10:1 engines ran at around 9-10L/100km.

fuel consumption on the road is all down to the quality of (and time spent on) your engine mapping.

Yep there are tons of much better ones on the market,
AGAIN I WILL REPEAT MYSELF NOT ONE THING MAKES POWER IN AN ENGINE ITS A COMBINATION OF THE CORRECT PARTS TO SUIT YOUR APPLICATION

No I dont think so without knowing why you would want a similar cam profile and what your complete setup is.

Sorry to be a pest but what car is it in and what gearing and really what are you using the setup for if its a daily I would not even think about advising on a cam profile.What does cut back type-R valves mean std ITR or modified ITR valves.

Forgot adjustable fuel regulator. Well I had a p72 head with standard valves. And 4 weeks ago upgraded to a pr3 with type-r valves. 4.4 early modle type-r gbox.
