Feedback on my engine setup
 

Hi masters of the Type IV,

I would like your feedback/comments to finish my engine build.
The idea is to have power & torque :lmao:
> 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,

Hi, Hi spec indeed for a streeter, but good luck with it.
It just so happens that i'm having a run on 228mm flywheel and clutch adaptions into T1 bell housings, these go in with careful clearancing, i don't know why the 215mm should not go in also, unless there's something unique about the 914 fly' that I'm not privy to?

Hi

I've had both 215 & 228 mm flywheels in bug bell housing, they do fit with some patient grinding, this was on WBX motor.

Thanks guys,

It exists at least 2 kind of 215mm flywheels, the Porsche 914 one, the only one forged in the vw air-cooled range of engine. It is higher than the other 215mm T4 flywheel. That's why it is more difficult to fit it in a std beetle gearbox.
