Quick Flywheel Question

[TRD_ZERO]

Im putting a e51 box onto a blacktop at a later stage and want to know if i can use my blacktop flywheel. Im not worried about clutches im asking if the blacktop flywheel will work with the e51 box or are the outer diameters bigger between the blacktop ones and gtz ones.

Blacktop flywheels are smaller than GZE ones so you won't have any problems fitting it in the box

So the starter motor will engage it no problem? Im just worried that it would be too small and the starter motor wont turn it.
