I have searched the threads and can't find anything on this so I I have a ke70 with sr20 and s15 gearbox and I was wondering what master cylinder and slave people are using?

if its any help, in my mates ae86 ca18det we used the standard ae86 master (same as ae71 and a heap of other 80s toyotas, celicas, hilux etc) and the standard nissan slave cylinder (whatever came on the ca18det gearbox)

 

given the way the nissan guys swap and change the engines from s13/14/15, id almost be certain that the ae71/ae86 master cylinder would definately work with the standard s15 gearbox slave cylinder.

Cheers mate I'll have a look into it

I cut the master off the 180SX firewall and intergrated it onto the Corolla,

 

It does recesss into the firewall, as i used the same pedal box to ensure pedal travel, spacing and strength
