Hi Guys,

I just wanted to share my experience with the Clutch Slave Cylinder sizing on my conversion.

I have run the standard EP82 slave cyl (3/4" bore) since I finished my conversion in May 2009.
It was heavy. Much too heavy for traffic driving causing my leg to get sore quite quickly. (I'm 6'1" and ride Mt Bikes pretty seriously and used to compete, so my legs aren't exactly weak.)

I changed the clutch for a heavy duty clutch and lightened flywheel I had floating around and the clutch got even heavier and "poppier" making getting away from stationary pretty difficult without stalling or spinning the wheels.

Anyway, taking the que from Josh's conversion, I looked into changing the slave to a ADM EP91 starlet one (7/8" bore).
The local REPCO had one and for $73 it was mine.

I Fitted it up today and bled the clutch and its 100% lighter with a much more progressive take up. I haven't driven it properly yet, but just in the garage it feels great!

I definitely recommend it for anyone with a 4EFTE conversion. I'd say my car is daily driveable now and before it definitely wasn't!

The part number is PROTEX JB9514 and the bore dia is 22.23mm!

DO IT!

Thanks for the tip James. Definitely on the to do list.

Have you notice any difference from the lightened flywheel?

Cheers

Cheaper again from eziautoparts.com.au too... I'll be hitting this up - cheers.

Answer the Question....
BUT always Question the Answer

I weighed both clutches with their respective flywheels and there was a definite difference in weight on the bathroom scales so I'd say it was at least 1kg, maybe more.(I didn't write it down )

The engine may rev slightly "free-er" but not like a bike or anything like that. I got more difference by dropping the back of the exhaust off.
The main improvement I got was the gear changes seemed to be more quick and positive. Its difficult to explain.
Negatives: Clutch got heavier and shorter pedal take up.
It also became easier to stall from stationary.

I removed a TRD clutch (STD?) and fitted a Ogura Racing clutch kit.

James - Are you using a Mini master brake cylinder?

Yep. Standard mini tin can type M/C.

UPDATE: I drove around a fair bit today with the new larger slave cyl and its still awesome. Almost like a real car!

Yay, it's worth it...glad that it helped

Mine is still quite heavy but usable..still wouldn't want to be in traffic for long but

I was running around with the heavy duty clutch and standard slave for aggeeess and it was a royal PITA!
