Tapping transmission case for GT2 slave conversion
#32
No ratttle here - just a very low engagement point. Based on the GT2 transmission machining, I would say on the TT to add 1/4" to the rod and consider it done.
Mine works perfectly with no machining or added length, so by adding the 1/4", you would move the engagement point up a bit, which in my opinion would be perfect.

You sell the Evoms GT2 conversion kit if I'm not mistaken. Why doesn't EVOMS package the kit with a longer rod to make the engagement point correct (not too low). It seems a little odd that if someone purchases this kit that they have to modify the rod length to get a proper engagement point. I understand that a low engagement point does not hurt anything but why not built the kit with parts that will produce a "normal" engagement point on the clutch to start with? I've thought about getting this done at some point but don't want to end up with a clutch that engages too high or too low.

I'm sorry, maybe I missed it earlier, but what is the advantage of doing all these mods to the gearbox as spelled out in this thread as opposed to just bolting on the conversion kit like the one sold by Speedtech? Is there any performance advantage per se?
#34
Well, i guess if you don't mind the extra work you save money, use non modified OEM parts and save a little on weight. It was more of a personal decision for me because i wanted it like Porsche made it for the GT2.

I don't have the EVOMS kit in my car. I did mine before EVOMS had a kit available. We did it from scratch using 993 GT2 parts - I wanted better clutch feel and my tech, a very experienced 993 guy had the idea - there was no kit available from anyone, so we purchased the parts, had a custom line made and installed it. We did not change the booster spring or modify the pump like EVOMS does. This is the first 996TT GT2 conversion I am aware of, so it was an experiment that went well. I mentioned it on the forum and owners were very skeptical to try it. However, one or two did and talked it up positively and the concept began to grow.
That said, I am not certain where the EVOMS kit engages. I have sold many, but never used one. I'm thinking it probably engages a little higher than mine, but I am not sure. Also, there is nothing wrong with engaging just off the floor, it works absolutley fine and is very easy to drive. I just "think" it would be better a little higher, but I could end up finding I like it lower, you never know...

However, if I were to do it again today, I would just buy the EVOMS kit and have it installed rather than experiment. You get all the parts in one stop, it's a direct bolt on application with no fabrication required and you have tech support. It's a much easier path and easier job with the kit for basically the same result - dramatically improved clutch feel.

I'm wondering why in the world Porsche made the overly complex and failure prone clutch release mechanism the way they did in the first place. Are the crowd that purchase new Turbos so soft that they require a sissy easy clutch pedal that one could push with their *****?
Sorry, had good beer tonight. But seriously, I'm wondering?

Porsche probably didn't intend for the clutch system to fail. Conceptually it looks good, but cost cutting got too aggressive so the made in Norway slave cylinder fails. They redesigned the accumulator but maybe their parts department likes selling slave cylinder since that part is what should be redesigned or outsourced to a more reliable manufacturer.
It seems that non-GT porsche are more grand-touring and the really good stuff is reserved for the GT models. Only thing for me is that there is no rear seat for kids option on the GT's

Not that I'd do it but wondering if the failure prone OE slave could be repaired using a different seal or even be gutted and modded to work without the power boost from the P/S pump similar to the GT2 slave.

So the clutch engagement point seems normal with the evoms kit since they have a longer rod? Does the kit come with the stiffer GT2 assist spring?
#43
Yes, the EVOMS kit comes with a stronger booster spring as part of the kit. Below is a picture of the EVOMS kit we sell - it includes everything you require, including the new fluid:

OK, i went for the first drive and i love how the clutch feels. Shifts are sooo smooth now. The only thing i need to fix is that it engages to high. I guess i should have left the slave rod as it was. i need to put a stock GT2 one in and i bet it'll be perfect.
Anyone have a stock GT2 slave rod you can part with?
