High comp B20 what cams??

[GSi_PSi]

how many MM are your sleeves ..


are you sure it adds up to 2L

as you would need to jump from 81mm to 87mm bore for 2L capacity

81mm bore and 87mm stroke = 1.8L

yeah 85 mm bore 87.2mm B18C stroke (That gives 1979cc with these pistons)

What head flow figures ?
What size are your throttle bodies ?
I don't think 170 Kw will be possible with this set up sorry ! Possibly 140kw - 145kw

Use Of E85
While is copes quite well with the compression ratio, there appears to be no other benefit, unless you had a turbo engine.
However on the down side, it uses a massive amount of fuel compared to conventional fuels, this means larger fuel lines, pressure reg etc. The blow by has a strong tendency to dilute the engine oil. The fuel being an alcohol type is hygroscopic in that it absorbs moisture. You can end up with a catch can that distils its own alcohol in it. Also like Methanol the car can be hard to start cold. While V8 tourers use the fuel they do so for more political reasons.
