i like the stock look... (964) its sleeper...
but for all this work, check out howard R's racer from ozzie land.. and his tilton setup with a bias bar brake setup and a hydroclutch. |

That was the conclusion I came to. It was easier to replace the lot rather than mess around adapting stuff. I think the cost worked cheaper to do it properly than with all the modifying, but i'm pretty well set up with equipent to do it. But maybe you don't need a proper balance bar setup to drive around the the streets. The throttle linkage took some thought (and messing around) to get right, but in the end was worth the trouble. I was after a balance bar, the hydraulic clutch was incidental, but now I have a clutch with a really short travel (but heavy) which is what I also wanted.

Felix et al,
Here is the correspondence I had with FTE about getting technical info on Porsche clutch master and slave cylinders. Maybe this will be of use to some of you: Dear Mr Hubby Thank you for your below email. I have discussed this matter with our technicians and found out the following: The maximum piston strokes are: KG19074.1.1 = 34 mm KN2393B1 = 21,6 mm -> and the clutch release path is 18,9 mm Hope I was able to assist you. Should you have further questions please let me know.

I need to know one additional piece of design information, the maximum stroke for the slave cylinder. I am using a stroke of about 21mm (measured from the neutral position at which the internal spring holds the piston, out to full extension) at present, and this seems to cause the rubber boot which seals around the slave shaft to protrude from the cylinder significantly. I am worried that I am in danger of pushing the piston out of the slave cylinder and causing the unit to fail. If this situation is normal (the protrusion) and the stroke is not excessive, I would like to know. Otherwise I can re-design the system to use less stroke but more pressure. |

I want to try the 964 asm since it's available and I can go ahead and plumb a reservoir and line to clutch cyl as I will have to do anyway. Whether I adapt aftermarket or stock components, both require calculations and/or trial & error (R&D). I believe if I duplicate the Boxster/996 components, I can avoid some of it.

I've been contemplating putting a generic hydraulic master cylinder behind the clutch pedal, giving it room to travel, then running a long line under the car, then to the back where i'd have a push slave cylinder (or a pull-type if I could find one...). Master and slave cylinders can be had inexpensively. It's just getting the part at the transmission to work correctly for a stock 914-901 gearbox that has me befuddled. Here's one way. Loved your quote from Word Jazz by Ken Nordine "...we are a fluke of the Universe...". I didnt know anyone else in the Universe knew that album. I just recently added it to my digital library....30 years after ... |

Is it possible to use the brake fluid reservoir to feed the hydralic clutch?
Thank You!!!! Phillip J. Haun Oak Harbor, WA. |

WOW! Excellent thread Felix. Look at all the cool advice. That's what this club is about (IMG:style_emoticons/default/smilie_pokal.gif)
