My vid might help, compares turbo and non turbo engines.
I assume the flywheel adaptor plate options use a stock vw friction plate, I know the rjes was and being a lightweight car can't see you having too much trouble with that setup. The difference between turbo and non turbo is night and day though in many ways. Again, shown in vid above.
If you find thr info even slightly useful you have to subscribe to my channel, that's the volks buddy law didn't you know? LOL
Oh any you can criticise my metalwork skills in this Sundays vid when it goes live! Ha ha. Actually don't I might cry
