hi fellas Ive got ca18 turbo in my 1200 sedan i didn't to the conversation the info i got
with the car that its an r30 stumpy box as i stuff the box and trying to get a new one
are these boxes the same as the s13 or where should i get one from im in nsw but it doesn't matter where ill freight it and also the short shift conversion for it
i do a bit of hill climbing with the car

Maddat sells stumpy boxes.

I have a d21 box which has stronger gears than the r30 stumpy and is only 20mm longer for sale
It a 71c stumpy

yeah ok do they fit in the same just 20mm longer do they use the same cross member
what ive been reading the r30 isnt that good anyway
harder to change gears when reving over 5000revs
how much and will you drop of to freight if i organize

As far as i can tell it all mounts up the same you'll need to swap the bell housing and front bearing for the ca18 one as this one suit z18/L series
I want $350ish for the box and I'm happy to drop it off at e-go in DANDENONG south for free if you sort it

im going to go with the ca18 box and put in the maddat trans tunnel
it seems the best option i think
tanks anyway

The ca18 silvia box has to be the worst choice of 71c out there. Is the longest box and has no advantage over a skyline or d21 box

You could always go Auto ???

so whats the best manual box for a CA18 turbo in a 1200

The D21 71C box Supafatto is offering is a bargain considering its condition

I will also add the 71c boxes on the d21 have improved dual synchros and larger bearings on the imput shaft as some Z guys use 71C internals these days but have some machining to allow for the bigger bearings. The R30 71B stumpy been much older they do suffer from overheated stressed shafts which are often passed in rebuilds but wont last long behind good hp.

Also the 71C also has a quick shift available for 50-80 dollars and a nicer improved setup similar to the Toyota W series.
