When you take the factory part and put it in the billet housing it just looks out of place lol. Seriously though, I wanted a part that added rigidity so we could really fine tune the preload on the carrier.  Many times the oem part is damaged by the time we get it.

 

Same goes for the OEM Diff cover on a Billet case.

Willall how about a properly machined billet bellhousing so we don’t have to listen to the damn rattling anymore. I bet you would sell tons of those!

Everyone does realize that the drive-train DESIGN is responsible for this problem?

 

The engineer talk that Jeremy Clarkson had with the engineers before he test drove the GT-R in the episode he broke his neck (supposedly) he made mention of it.

 

The drive-train only lines up perfectly under load.  When fully accelerating, the annoying rattle is gone.

 

But that design wears that bellhousing terribly over time.  A lot of design changes have been made to improve it over the revisions to keep the wear down, but with that design there's no way it can be permanently FIXED.

 

The aftermarket has made some attempts to fix it (including WillAll), but they are fighting the original design.  Unless the driveshaft has some redesigned flex points or mounting angles I'm not sure how that can be fully addressed.

 

On the other hand, there are several first year CBA's around that have the original bellhousing.  Mine included.  It rattles like hell until it is warmed up and under load, but as long as it doesn't damage the motor (I know it can under certain circumstances) I don't feel compelled to replace the bellhousing yet.

Very informative post. Thanks for sharing. I just chalked up the rattle to the normal mechanical orchestra we experience on a daily basis.

I remember that scene in the gtr episode of top gear. If I remember correctly he was talking about the suspension not the drivetrain. Does anyone know if this rattle is a common issue with the R32/R33/R34? If they could make it not rattle back then I don’t accept any other answer as being anything other then a cover up.

I was CONVINCED I could find that statement somewhere with clarkson.  Somehow I cannot find it for sure now.  Dammit.

 

But I remember it somewhere from the gajillion factoids we got in the first few years.  Clarkson DID say that each engine was tailored to work with only ONE transmission.  I'm not sure that's exactly right.

 

But the suspension is assembled on a jig under load.   You are right about that.
