hi guys im after just a rough guide on what i have to do to convert an l series 63a 5 speed into th a series one. i have both and the a series one is worn beyond easy repair, so i got an l series 63a 5 speed out of a stanza. to my knowledge all i have to do is lathe down the input shaft. is that all i have 2 do?
cheers kurt.

yeah isnt it just the bellhousing the input shaft that are different. so pull the l series box down and get the input shaft out and hit it with the lathe

if you have both boxes you should be able to see any other differences

Well bell housing would be a lot different to my knowledge. Just send me the stanza 5 speed i will make good use of it. Mines getting a bit funny with 1st gear Maybe cause i like to hold it there for to long .
Edit Pig was to quick once again.

To my knowledge, no one has ever done this. Many have talked about it.

Woody, let us know if you can make it work.

*sighs,

Ian used to make a thin adaptor plate to sort out the bellhousing issue on his speedway sunny before he went full L series....then CA

It's a bit tricky turn down the input shaft. There is nothing to hold it by. The one I had turned down had to be held in a tapered jig that held it by the tapered synchro ring journal.

and i wouldnt be trying it if you havent done any lathe work before
that would be hardened steel, alot harder and slower to machine then mild

Send the input shaft to me and I'll use a proper grinding machine to reduce the input shaft diamater. Lathes are inprecice for this sort of thing. At the very least you need a monoset to do the job. I can't remember who has done this before on here but they have used the stanza input shaft. There is no reason why you can't just make the brass spigot larger to accomodate the input shaft of the l series but you will need to shorten the spigot length on the input shaft.

If you need, I'm happy to do some grinding... I think I know someone who works at a place that may build gearboxs.......

Hey Woody,
my 2 cents worth .........
Stanza dogleg boxes are weak as p#ss
Okay I suppose for the rally work they were meant for but they don't stand up well to horsepower. After using the 260Z close ratio box I won't use anything else - so good that I bought one of Errol (Datrats) reco boxes. If you are going to go to all the hassle of making an L series box fit - then go for a strong close ratio - it will be far more rewarding.
Cheers

r-fast this is for an A series not an L
and horsepower has nothing to do with breaking a box. the l series will always have more torque then the A and that is what breaks them not the hp
