I just won them on Ebay but the description was pretty rubbish so didn't list any information, does anyone know what make they are so I can find out what the ratios are & what sort of power/tq they can take!

No one?

Bill

 

u gave us a picture of gears with no symbol or numbers to go off of .... that could be any company that makes those gears .... or it could be some no name company

 

I see both K- and B-series countershafts. But can't tell you much with the photos you've shown.

 

That's the pictures I have until I receive them!

If I had symbols or part numbers I wouldn't need them identifying

Bill

 

Interesting you see K series counter shafts, I've not seen a K series tranny in bits..

I'll pop up some more detailed pictures once they arrive

Bill

 

Yup. The three countershafts stacked up like a pyramid in the photos... the bottom two are K-series.

 

So the first lot here seem to fit the B series input shaft that came with them.

FD ring gear that seems to match the input shaft above.

Second lot here seem to be a mystery as they have have five dog teeth but don't look the same as the parts above?

Ok so the third & final lot of ratios seem to fit the "K series" counter shaft.

Missed your post there & forgot about this thread!

I've been busy racing my car & enjoying the summer along with working but I've just bought a K20 to swap into my CRX over the winter so I'm having a clear out so this is back in my mind


I didn't get much further, it seems the B series parts could be for a cable tranny & made by Hewland.

With the K series stuff I've not really got much further forwards..

Seems the gear sets are from a race team that shut down called GR Asia, they had a DC5 race car that raced at Macau & did well originally built by a company called JAS Motorsport who seem to be from Italy!

Here's more pictures of the K series stuff...
