260z gearbox

anyone know how to identify, the better 260z 5spd manual box, with the porsche type syncros, and the shorter ratios....

and did all 74 260z's come with this gearbox, or till what month of 74 did they finish putting them in etc etc

my 280zx gearbox filler plug was on the right.

my 280zx gearbox filler plug was on the right.

Then it was a 280ZX gearbox with a 260Z bell-housing. I've seen it done, and more than once. There's a certain well known Z-wrecker in Melbourne that's been known to pull that sort of stunt on the unsuspecting.

so lambs, you are saying that the oil plug is on the right for the good 260z good, or on the left, and is that looking head from front of car, or looking from rear of car...

Then it was a 280ZX gearbox with a 260Z bell-housing.

Didn't I say that it was a 280zx gearbox? I'm not sure what your point is here..... and it wasn't likely to be a 260z bellhousing, since it was the box that came with my L28....

Doesn't matter what you said it was or what it was bolted to, 280zx gearbox is exactly the same gearbox as 240K and C210 Skyline (ie FS5W71B) and from the factory has the oil filler on the passenger side. Only, and I'll repeat that, only 240Z/260Z gearboxes (FS5C71A and FS5C71B) have the oil filler on the drivers side.

 

The fact that your gearbox has the filler on the drivers side says straight away that it has a late 240Z or 260Z bellhousing fitted, for whatever reason - it's quite easy to do. So my 'point' is exactly what I stated, and I'm not sure what's so difficult to understand. You seem to think I'm 'having a go' at you, but all I'm stating are the facts and those facts come from many years of experience with these gearboxes, not just 'reading' something on the internet or in some book.

so what you are saying then, is that the oil filler plug is in the bellhousing, not the gearbox? In which case, wouldn't it have been simpler to just say in your first post that its irrelevant which side the gearbox filler plug is on, because someone may have swapped the bell housing anyway?

And as for this:

You seem to think I'm 'having a go' at you, but all I'm stating are the facts and those facts come from many years of experience with these gearboxes, not just 'reading' something on the internet or in some book.

How about answering the question that this thread is all about, using those 'years of experience', so that the rest of us don't have 'read things on the internet' to 'find out' what we want to know, then have some smartass turn around and say thats wrong, and not fully explain himself, or give a complete right answer. Its not the first time you've posted some comment about 'that can't be right, because from my experience', then disappeared and not answered the question that had originally been asked by someone - if you can be bothered to post and tell someone they're wrong, then you can be bothered to answer the question being asked in the first place.

What I believe Lambs is referring to is the fact that on most of these boxes the bell housing is one piece that extends down, covering the gearset, to the rear extension housing. Swapping the gearsets over using whatever bell housing you like is relatively easy I believe (I swapped my S14 71C gearset into a 280z bell housing).

So it would be relatively easy for someone to put a 280zx gearset into a 240z/260z bell and say ``look the plug is on the right, its a `good' gearbox''.

If it were me I'd be selecting 1st and counting the number of rotations. 2.9:1 is the `good' gearbox ratios I believe. Not too sure if those ratios had the `good' synchros or not and I CBF looking it up atm.
