ok, my box is in, i used the MX7 tailshaft, used an NA VL starter motor, NA VL flywheel with a nice clutch built for it, the clutch was a skyline clutch so i used the skyline throwout bearing carrier and i used the R33 slave cylinder. Used the MX7 speedo drive. All works fine and feels great. Only mod was i had to slot the starter motor holes in the MX7 sandwich plate to suit the box. Took about 200 photos, will do up a tech article when i get time Cheers Scott.

fantastic work 87calais - you've just done exactly what i was planning on doing down the track. only difference is i'm getting a VL clutch built so i will use the VL throwout bearing and the VL slave cylinder. back to the clutch feel question: i'm going a big, heavy full face organic clutch. is it possible to a) bore and re-sleeve the master cylinder with a bigger piston? b) same but with the slave cylinder? <--- though this may impact on the amount of throw it would have if you didn't do (a) first..... c) modify or fit a larger master or slave or both from a newer model car? like a HSV commodore or something i imagine would have a rather beefy master cylinder and slave.....

i used the r33 slave and it isnt too bad, my left knee hurt a bit for a few days but now is all good. i have a button clutch and although it doesnt like slipping you can take off quite easily, quite hard to stall the rb actually, well mine is. modifying a vl master wouldnt be impossible, the way its mounts to firewall will be awkward but a machined up spacer should do it. the vl slave has mounting holes on opposing sides of slave and the r33 one has them on the same side. i didnt like the idea of a bracket to keep the VL one steady.
