Noob with a new mx5 Saturn build.

So I've made up a clutch hose and bled the clutch. It works but it's unpleasantly heavy.





I was looking for a 0.65 cylinder to try but no one makes one.

If the pedal is too hard, you want to reduce the diameter of the master cylinder, not to increase it.
Good job with the clutch line, it looks nice.

I considered the 0.625 mc but thought that was quite a jump. Nevertheless it looks like the next available option.

My car uses a 0.7 cylinder and the clutch feels just right. I do have an larger diameter hose going between the two. Not sure if this makes any difference but when I had it made up be furore he suggested a larger diameter

I remember skov having a stiff clutch problem as well.

That's interesting, I'll fire a message to furore for advice. I've used a -3 hose and m10 banjo fittings. All the moving parts are friction free so it's definitely a hydraulic issue.

the banjo fittings may be your issue, try a bit copper pipe in with standard male ends before you go spending any cash.
some master cylinder to slave setups do use 10mm pipe but not on the mx5

I don't know what the standard ones dia is but that is what I am using and clutch feels fine, and I am using a flexi line as well

[norton]

I don't know the pedal box dimensions/pedal leverage but it's all as per the Saturn plans using a 0.7 mc.

Top hose.



Bottom hose/inlet.





And to make this work I made up an 8mm copper line to route coolant from the cold start/fast idle valve to the water pump inlet.



So asides from the expansion bottle the coolant pipes are done. I also wrapped the exhaust manifold because I felt like a tart...

I've been putting off the brake pipes as they have the potential to completely cack if not formed perfectly. I can't put it off any longer though, they have to happen.

My next update will likely be in a year or so's time.
