Information to understand My cousins thoughts to get a opinion or **FACT** to see if this will work or if its even possible....... If you familiar with the F20B and F23 Internal Specs then read at the bottom.
Deck Height :
F20B - 219.5mm/8.643
F23A - 219.5mm/8.643
F20B - open deck
F23A - open deck
Bore :
F20B block - 85mm/3.346
F23A block - 86mm/3.385
Rod Length :
F20B - 145.0mm/5.709
F23A - 141.0mm/5.551
Rod Width :
F20B - 23.75mm/.935
F23A - 19.81mm/.780
Main Bore :
F20B - 48.00mm/1.890
F23A - 48.00mm/1.890
Pin Bore :
F20B - 21.97-21.98mm/.8649-.8654
F23A - 21.97-21.98mm/.8649-.8654
Piston Bore :
F20B - 85mm/3.346
F23A - 86mm/3.385
Compression Height :
F20B - 31.0mm/1.221
F23A - 30.0mm/1.181
Piston Volume :
F20B - +8.0 cc
F23A - -18.0 cc
Wrist Pin Diameter :
F20B - 22.0mm/.866
F23A - 22.0mm/.866
Crankshafts :
F20B - 88mm/3.464
F23A - 97mm/3.818
Main Journal Diameter :
F20B - 55mm
F23A - 55mm
Rod Journal Diameter :
F20B - 44.98mm/1.771
F23A - 44.98mm/1.771
Intake Valve Diameter :
F20B - 34mm/1.34
F23A - 34mm/1.34
Exhaust Valve Diameter :
F20B - 29mm/1.14
F23A - 29mm/1.14
Combustion Chamber Volume :
F20B - 53.80cc
F23A - 50.00cc
Head Gasket Bore :
F20B - 85.5mm/3.37
F23A - 86.5mm/3.41
Head Gasket Thickness :
F20B - 0.66mm/.026
F23A - 0.66mm/.026
Main Bearing Width :
F20B - 19.9mm/.784
F23A - 19.9mm/.784
Based off this information is it safe to use a F23 Crank and Rods(which will really be a Eagle Light rod to be on the safe side) with F20B pistons in a F20B DOHC Vtec block
Creating a
Rod/To Stroke Ratio 1.45:1
Mean Piston Speed 2147fps
Displacement 2201.71
Compression 12:53.1
Using a .030MM Headgasket.
What do you guys think? This is my cousins thoughts and he doesnt know english.
