r33 clutch fitiment

[barman]

here is my problem

i have a r33 non turbo and have been told i can get a 2.5turbo but the only thing is i dont think it will fit as the flywheel is 9 bolt and the non turbos are 6 bolt but my question is can i get them to fit in anyway at all or will i have to spend nearly 300 on a new clutch for non turbo

all turbo models are interchangable with each other
all non turbo are interchangeable with non turbos
but turbo one wont fit non turbos

any solutions please
