Well, it seems that there isn't a kit on CB performance. Although I am getting the clutch from there as it's cheaper that other websites

Any other suggestions are welcomed as I want to make the car as good as possible

Thanks

Does your clutch pedal pivot from above or below? CB does show a kit (from CNC
Hydraulics) that has the clutch master mounted on the pedal- if your current pedal swings from below, then you can use that- bolt the master and pedal assembly to the floor and route the hydraulic line to the back of the car.
If your pedal pivots from above, there's another pedal set-up (I think through
CNC) that works like that, but the master is re-oriented to right side up.
Method number three would be to use a master with a remote reservoir, so as to not have to mess with hydraulic fluid inside the car.
The big thing with hydraulic set-ups is the master bore sizing vs slave sizing. A 3/4" master, and 7/8" slave works well, but may not quite throw far
enough, and so you may need to adjust the pedal ratio a bit. With a master that
is the same size as the slave, you only risk having too much throw, and too much effort, but this is easily taken care of by changing the pedal ratio to
get more leverage. No matter how you do it, do not end up with a master larger than the slave!

Troy,
Follow this link to a thread from a few years ago. there are some pics of converting the VW bug to hydraulic clutch system. Hope they help.

The stock cable system usually works well maybe not for a stage III pressure plate but a good new Sachs or Kennedy I .... I would keep the cable set up. Replace the cable itself if yours is questionable then hammer down. The old crown flywheels aren't great they work but ...... find a steel modified VW flywheel it can always be lightened too if you like light. Both surfaces including flywheel and pressure plate need to be primo when putting bigger power to them. The stock style cush VW 200mm clutch discs work fine but you need to be able to clamp down on them good this is what the pressure plate is for. If you have any oil issues in the bell housing then switch up to a puck style that may overcome some of the oil slip.

Good driver or weekend race car are 2 different machines. nope can't have both. if you make one that does do both it won't be Great at either. Build to suite and enjoy smileys with beer .... just get 2 cars !

Thanks a lot Rod, that is a good thread on that, great work! Where did you get that kit from then, straight from CNC? Looks easy to modify.
My clutch pedal does rotate from the bottom, and I was thinking of getting the Kennedy 111 clutch as well with the 4 puck disc, is this a good idea or is that overkill, and wont be able to drive it properly?

I also am looking on the cb performance website and found a kit but dont know which will require less modification, all will require some and I dont know whether it's easier to get the floor mounted one and ditch the stock pedal, or do what was done on that thread?

Thanks

My opinion : For a street car I would leave the stock VW pedals and clutch cable. They work good and the pedals in VW bugs feel just right the way they are.

If you really must or want it bad enough.... the aftermarket VW scene when it comes to pedal systems I try and stick with CNC quality..... or better... No weird empi / China if it's going to be on the road. The older girling stuff lasted fine I think those were all dot approved. 5/8 master on the clutch side is plenty for the CNC brand slave on a VW set up.

So I got the Kennedy 200mm 2100 lb. Clutch and super disc, that should be heavy enough right? I would think so....I don't know how heavy the crown one is but it slips pretty bad once turbo spools
Anyone used Kennedy clutches?

Stock turbo's... usually around 3,000 rpm...

Takes several $$$ mods to get them to spool faster..

Do you know how your turbo is built?

No need for a Vair engine to leak... with today's seals..

Sell? after all this hassle? Keep it for a "Toy"

Yeah, but thing is, kinda wanna get ahead, things like that unless I sell quick I'm gonna lose money on it. You know what I mean, you always will spend money on it. It is a toy definitely and its fast, but hey? I dunno. Was a project and would like to make a little money on it before something else breaks. Actually you know for something I completely rebuilt with no clue how to do it, it runs really good.

Possibly would be a good idea but I drove it from columbus oh to Cleveland, 2hr drive at 4500 rpms while time, exactly what I hate about the vw tranny, you can max out 4th easy
But anyway yeah, might be a wise decision. In all seriousness I've had so much fun and learned so much more than any college could teach me ever. Not saying college is bad, but I think everyone should do a project like I did sometime in their life. You learn a lot
