Hi dat2kman, I take it these will fit in the 260Z's ?

Once you modify the stock 260Z bellhousing, so that the SR/RB box fits into it,

Rear mount needs altering, and if you use the RB box, you retain the stock 260Z tailshaft.

Is there much benefit in changing from a late 260z 5speed?

Bigger mainshaft, wider gears, thicker 1-2 selector rod, stronger selectors.

Built to handle Nissans newer Turbo engines.

Depends...

 

Bigger mainshaft, wider gears, thicker 1-2 selector rod, stronger selectors.

Built to handle Nissans newer Turbo engines.

Ratio's are crap compaired to the close ratio 260Z gearbox's though

 

If you are making over 300hp / 250ft/lbs of torque, the later 71C box's are the go.

Thanks guys, I will have to check what the gearbox is that is in it, it's a 77 260z 2+2.

Jason, do you have any spare shifters, shifter plate and the little clips/spacers to go with it?

 

I've got a spare SR20 box without any of the shifter parts on the rear casing.

Sorry Gareth, those bits, and L series Bells are the items I am low on

Have a hunt around on some of the drift type forums, or visit some Hi/Po workshops, as these boxes, once blown to smthereens, by aforesaid drift types, just get binned.

Bear in mind there are slightdifferences between RB and SR shifter flat mount plates, make sure youget correct to suit your box.

Will do. Thanks mate

Hi , Just wondering if I can pick your brain?

 

I had a S14 silvia gearbox fitted with an RB gearbox  extension housing pieced together and mounted to my L series bell housing so that overall length of the gearbox was the same as the original and retained the original tailshaft.

 

If i had gone with complete S14 gearbox on the L bellhousing I would need to shorten my tailshaft.

 

My question is : I had to re do the rear gearbox mount to fit my hybrid gearbox which is  approximately 35mm further back towards the diff, Would the Silvia gearbox mount to this or is the distance different again? 

 

Thanks,

 

Craig

Thanks for the info!

This modified mount and shifter will most likely be up for sale this week if anyone is interested.

I tried my best to make it factory looking
