G40 Issues please help

[Kappa]

Hi All

I am looking in buying a Polo GT with a G40 conversion.

The issue with the car is if you floor it and it revs past 4k rpm, the Dizzy cap cracks?

Guy has uprated the cam to piper cam and has a 68mm pulley. He even tried superglueing the rotar arm on and that cracked the Dizzy?

Any ideas what this could be and any help appreciated.

Thanks

Id try a new dizzy.

The g and gt rotor arms are different too I believe so ensure he's not using a Cl spec one
