They are pretty rare. I'm not aware of any for sale right now.

The celica 6speed is more readily available. Usually $800+ (probably $1000+ this time of year), you'd need to swap bellhousings and use mk2 NA axles to make it work.

on a 20V black top what would i need to use a 6 speed? in aus i know i can get them but i dont know what other parts are required.

thanks

You could use a blacktop 6speed just like a blacktop 5speed. The main problem is still the same, the lack of a selector shaft oil seal casting.

how would i go about it, would this be a custom job? sorry this is one thing i dont really know about. do you know if all blacktop 6 speeds came with an LSD?

I am not so sure that any C series transmission even came with LSD. If there are some out there, it is a rare option.

In the case of my blacktop c56, I just switched center transmission casings. The BT 5th gear set is nice in that it has two bolt holes for a steering wheel puller, so taking the tranny apart does not require a SST.

the levin BZ-V and BZ-G had the black top and 5 speed with a helical LSD and
the levin BZ-G and BZ-R had the black top and 6 speed with a helical LSD.

I have a standard 85 trans in my car do you know if the 6 speed gears fit? would the diff be a swap too?

thanks
