G50 in 911 conversion question

[PorscheDV]

i definately want to grab this tranny!!...its a 95 6spd tranny, that i want to use in the furture when im ready in a 76 conversion...i know of patrick motorsports and how they do G50 conversions...but i want to use the 6spd tranny and they havent replied to any of my questions concerning usung the 6 spd instead of the 5...is it possible?if it is..i know i can make it work and i dont doubt my capabilites..but are there any design quirks that may prove making this conv. impossible or at least WAAY above and beyond practical (im not too practical myself, i tend to do things that dont make sense for the sake of saying i did it!)

thanks!

Anything can be made to fit if you can fund the trial and error.

Of course, it may be an impossibility as 993s have a much different rear suspension system.

If a 993 engine can fit a 915 transmission, then logic dictates that a 993 transmission should fit what I assume is a pre-EFI Porsche engine.

I'd be very interested to find out if it's possible!

Although I haven't personally installed a 6 Speed into any earlier car, I do know that many have made their way into 964 based cars with little difficulty...I would assume that it is not that big of a deal.

One factor with the G50 conversion is the fact that it's longer than a 915. Patrick Motorsports (and others?) make a shorter front nose housing that avoids having to update the torsion bar tube. So the questions will be:

How much longer is the 6-speed compared to a shortened G50 5-speed?
How to mount to the chassis?
How to adapt to existing axles?
How to adapt to/change to proper shift housing?
How to actuate clutch mechanism?
How much heavier is it than the alternatives?
What is the cost versus benefit ratio?

Hmm...ok i know G50's have been put into pre G50 cars...(are these the 87-88 G-50's? or 964 based G50's as well?) if they are 964 based, then couldnt we say 6spds go into 964's...964 based g50's go into pre-89 cars..therefore a 6spd can be modified to fit my 76? i know i can do G50's, it been done quite a few times...but is the 6spd longer, shorter, fatter? making it a completely different affair than the 5 spd?

anyone?!

ah! ok...this is what im asking!
does anyone know if the 6spd longer than the 5?
as far as mounts, axles, shift mechanism, and hydro clutch, im assuming (read as hoping) they're the same as the 5spd, can anyone confirm? if so, i'll use any conversin parts from patrick and or fab. my own...

as far as costs...provided the 6spd, would cost the same, or near as the 5spd (and not require thousands more than the 5spd) ive decided the 'just to do' factor outweighs cost for me...

oh, also, since im converting to coilovers, do i need to shorten the tranny? (as i understand the tranny was shortened to avoid mod'ing the torsion tubes, with them eliminated, it shortening still neccesary?)

[stlrj]

I understand that cutting out the torsion tube and going to coilovers is the most cost effective approach since it would eliminate the costly shortened tranny from Patrick.

I want to know if the 6-speed would fit into my 77. This could be a party waiting to happen. Some one must know about this. I can't accept that nobody can answer this, not on this site.

[Bill Verburg]

To fit the 6 spd. the torsion bar tube and sheet metal need to be removed. Coil over suspension and semi tube frame required.

The short G50 5spd will fit with lots of extra work.

sounds like a very involved (read as difficult and high $$$$) proposition. Why not a Ruf 5 speed or G50-50? ...... much easier project and one less gear to shift.

I really only red line the first few gears, then up shift into 5th anyway.

Although it would be unique though...

(I like unique stuff)
