Just got my car mapped and made 524hp which was good but now have a prop noise as it didn't like it!! which is bad I have a whirring noise coming from the prop on my r32 gtst,it is quite high pitched and rises with the revs I'm led to believe it needs a new propshaft centre bearing but cant find one for sale anywhere? I'm not gonna bother with Nissan as no doubt they will be £££££'s unless I really have to. Anyone know any suppliers? I've searched but found fuck all!
