Hi masters of the Type IV,
I would like your feedback/comments to finish my engine build.
The idea is to have power & torque
> 2366cm3 (71x103mm)
> Max rev 7000-7250 rpm
> mainly street use but would like to go also on the track
> CR 9.5:1 or maw 10:1
I will be pleased if you can advise me on the valve train & flywheel selection.

Flywheel option
I've got the original forged 215mm 914 flywheel nevertheless it will not fit a std beetle gearbox.
Does it exist a diameter of T4 flywheel that willl fit both T1 beetle gearboxes AND Porsche 901/915 gearboxes ?
In any case flywheel will be lightened and balanced
Cheers,
Obi
