John save your cash and get the sein system kit, it is almost identical to the robotek and costs around $150. I have no experience with the Wevo kit, but my recollection was that it cost around $700. The sein system kit is available directly or through performance products.

Roamer,
What's your experience with the Sein kit? Did it really improve the shifting performance of your 915 trans. Any feedback is very much appreciated. I have included Robotek Kit for my X'mas wish list. Thanks.

To keep it somewhat objective, here are some threads on the subject on that other BB:

BTW, the Gate Shift kit is not yet carried by Perf. Products. Tweeks is one supplier, as is the source.

Hey Sherwood are you working on heat sheets for 993? Seems like they would be a natural as the factory deleated the ones used on the 964s. I for one am in the market.

Bill,
I've had this in the back my mind for awhile. I believe the valve cover bolt pattern is the same as the 911. However, these models use a smaller thread (6mm) which would allow the current HeetSheet to fit.

Can you verify this for me: some valve covers are attached with bolts; some have studs.

Thanks,
Sherwood

Sherwood,
964 uses a 6x25 stud, 993 uses a 6x30 screw. 993 turbos use a longer 6x35 screw because they have a small heatshield.

An additionl potential product is a shield for the "S" hose. I can make one but that's a PIA. I'm lazy. Or the "S" hose itself, I keep meaning to have a fully radiused bolt on ss stainless pipe made at one of the local machine shops, its necessary for a transplant. Hasn't happened in 8 yrs.

Bill,
Do the fasteners also attach the factory heat shielding to the valve cover? Looks like I need to get ahold of one of each to verify fitment.

Marc,Thanks for the information.I have been of sherwood's web site and have read your post on the installation.I have the factory short shift kit.How much more difficult is the installation with this set up?John

I have both the Robotek and the Wevo internal gate. If I had to do it all over again, I'd get the Seine kit.

Of course, none of these devices has anything to do, really, with how a 915 shifts. They reduce the likelihood of a misshift, by providing a spring to center the selector in the 3-4 position, and Sherwood's adds a lockout gate. But none of these devices will do a thing for you if you've got Synchro, dogteeth or bearing problems.

The most notable shifting improvement, outside of a rebuild, will come from new bushings and a good adjustment to the linkage. The advantage to the gate shifts is about saving you from the $9000 bill that comes when you put the car in 2nd when you mean to downshift to 4th.

Is the Seine kit worth it for this reason?

Absolutely. I wouldn't track a car without it.

Roamer

Jack, as usual, is right on. It does make you shift more CONFIDENTLY because you know where the shifter is heading as you shift thought the 3-4 gate.

John I also have the factory short shift kit and put it all in at once. As for install, not too difficult, get yourself a nice rotorary tool to cut the housing and smooth the surface and have someone weld the bracket to the shift lever once you have it lined up. If you get into it and have some difficulty, do not hesitate to ask.
