s13 gearbox internals??
 

hey does anyone know if the s13 gearbox internals fit inside the s12 bell housin??

I should imagine they would fall out the whole where the clutch release bearing arm goes.

They may fit better inside the gearbox itself :D


Sorry Bud lol

rite just coz i found out that the s14 internals fit in the s13 bell housin so if the s13 internals fitted in the s12 bell houin then maybe s14 internals inside s12 bell housin and resultin a lot better gear box... lol

you will not get the s14 clutch to fit the s12, its to big, i know, i got one supplied for the s14 by mistake, the s14 thrush bearing fits better than the s13 one though.

You could just use the complete s14 gearbox. the shifter is 2 1/2 inches further to the rear of the car so you would have to adapt your geargater slightly though. Then get the propshaft shortened.

JAPSTER uses an s14 gearbox. Or call Norris designs as they did his for him.

is he a millionair ? lol:D

yea think he must be:rolleyes: , was just thinkin of seeing if there was anything i could do to improve the box since in wreaked the old one and have to rebulid it......:(

I find my mk1 gearbox great.Shauns is holding out well too etc. USE redline heavy duty gearoil. She will love it. i just think you have been unlucky.

o rite cool will just crack it open and fix the knackered bits, you wouldnt happen to know where i could get a 280z short shifter from..:confused: cant seem to find them forsale anywhere????

280z short shifters are News to me Fella. Any info you find post it up lol :p :cool:

Unfortunately it does seem the S12 gearboxes are a bit of a weak link, with about the same strength as the S13 ones.

I've look at bellhousing swaps before.

I haven't looked at the comparison behind the mk1 and mk2 bellhousing bolt patterns. But I'm assuming they're different. I am also assuming though that the mk2 shares the same bolt pattern as the s13 box

Get an S14 box. Get a wrecked S12 mk2 box (i have one)

Removed the bell housings off each, and bolt the S12 bell housing to the S14 box.

Then see where you stand with the props. You might find a mix of mk1 and mk2 props might give the required length.

i used to use mk2 s12 boxes, but now use s14 boxes with s13 bellhousings. im pretty sure a mk1 bellhousing wont fit the s13/14 boxes. The s14 box with S13 CA bellhousing needed my propshaft shortening by 50mm, and moved the gear lever back 65mm.
Think the s12 mk2 bellhousing will fit the s13/14 boxes (but not tried it)

Yes this is What Norris designs did on japsters s12

yea if i can get the parts i mite give it a try and see what fabrication is needed if it looks like it mite work, just trying to get parts on the isle of man can seem somewhat difficult or expensive......:mad:


refering to the mark 1 gearbox with the short shifter from a 280z
