thxs heaps to you and chris

next problem,,,,car dropping in revs when i reach between 100 to 140 ,,,feels like a fuel cut or rev limiter but not sure

suspects :
1. spark plug is bkr6eix -11 instead of the normal zfr6 stuff
2. change leads to a 10.2 mm
3. iacv
4. tps

[antish_r]

anyone ?

Could you be more specific about it dropping in revs? If you can hear it drop, and feel it drop I'm assuming it could be a clutch slip. When was the last time you changed your clutch?

[antish_r]

clutch is new

I don't see the corelation between your problems and a b20.

You should start a new thread.

Been driving my b18/b20 for about 4 months i was afraid to go past 6k rpm when i first got the engine and now im regularly pushing it to 8k rpm. Not one issue yet and the torque is heaps of fun.

Why?

You don't know what he's done to it.

whats peoples thoughts on b20's fuel consumption? with honda being green and efficient and all. for daily sub 3.5/4k rpm driving whats peoples thoughts on a stock high comp b20 vs a stock block and stock head b20 vtec?

both with the same boltons and stock internals/cr's 10.0 or 10.2 vtec (i guess intake mani/ tb would be specific but keep the headers/exhaust and intake arm/filter the same)

smaller ports/intake valves in the p75 head for better low rpm velocity and lower rpm powerband manifold, especially with 2l of displacement. swirl with the staggered primary and secondary lobes in the vtec head. and small bump in compression (i guess the increase in displacement would help with lower rpm velocity also...


i assume built b20v high comp pistons stockish non vtec lobes and associated work would have better km/l then stock.

all options tuned of course

thoughts/experiences?




i imagine the stock r/s ratio would wear the rings/walls a little faster then a b16 at 8k, regardless of how well balanced ect the bottom end is.
dosent mean its gonna die in 5 thou klms though... what do you mean b18/b20 p72 head?

I also want to know the reason for this

Because zeni-tani doesn't know how to build a reliable engine.
