Hey guys,

I have finished fitting braking and handling components to my CA18DET 1200 and am starting to consider drive train combinations. I just wanted to get some opinions off fellow 1200 owners before making a decision.

Basically, i want to use the standard ca18det gearbox as i beleive it to be much stronger than the "stumpy" gearbox, and even though its harder to fit would be better in the long run, what do you think?? is the stumpy box any good under say 200kw 20psi conditions??

Secondly i am using a r31 siloutte LSD diff, shortened and i need a one peice tailshaft to suit. Now if i go with the ca18det gearbox then i need a tailshaft to suit. I understand that i will need to get the gearbox yoke swapped on regardless as the ca18det tailshaft only came in 2 peice, but does anyone know of a one peice tailshaft that has the r31 diff yoke on it already so i only have to get the gearbox yoke replaced??

Any help is much appreaciated,

Cheers,
Hayden

With the tailshaft issues, you can just use an L series tailshaft and just have the rear flange changed to suit the borgy diff. Make sure you measure how long a tailshaft you need because I found there were several L series tailshafts that were too short for the application.

ca box has better ratio's, i used a late model stanza tailshaft, just needed to be shortened,

Daveman: will the l series shaft suit both gearbox's? or only one of them if so which one?? Cheers

Short-coupe: with the stanza shaft which box did you use? also are you running an r31 borgy diff? if so are you saying that the stanza shaft had the correct yokes just needed to be shortened and went staright in? thanks for all your help guys

I used the stumpy box and R31 diff and found a 1600 tailshaft fits, you just have to swap over the rear yoke with the r31 yoke as they are a direct swap.

My stumpy box with a 80kW ca18de never used to shift above 4500rpm. When drag racing I had to crunch all 4 gears during gear changes ...they are rubbish.

Do the extra work and fit the S13 box.

yerr mate, had correct flange & yoke, i'm running the CA box, with a r31 rear
