Six Speed 915!

To answer the question about active first gear, it’s just a reference to a ratio that’s tall enough to be usable on track, usually 65-75 mph. I’m not aware of anything different about the synchro function compared to a standard first gear - same parts.

Correct.

From Albins, this other tranaxle not for Porsche which resembles a G50 if anything, supports both variants .... though not in the 915 form factor but ... who knows.

Hey, that looks familiar

There's some quirks about the 911 I love and there's some I could live without. Clearly Porsche agreed when they swapped to the G50.

Also, given the prices these days, better to work with the car you have.

Not sure why people feel the need to gatekeep what others like or don't like. Plenty of mods I see here that I absolutely hate, but you know what I do? Nothing. I skip to the next message. You enjoy your car your way, I'll enjoy mine my way, that way everyone is happy. Yours isn't "correct", it's just yours.

Just rebuilt my 915 and have a Numeric shifter, so it shifts fine for a 915 - but it's still way more clunky than anything else I've ever driven.

There's not an official thread yet, but stay tuned.

I am not sure why people like you feel the need to gatekeep opinions.

Putting a Subaru gearbox in a G-body 911 will certainly change the character of the 911 and will most certainly lower the value of the car.

Porsche changed to the G50 for multiple reasons. Chief among them was to better deal with the expected increases in torque/power and to modernize the shifting behavior. The added weight and change in shifting behavior was not considered a positive change to the experience and character of the car by all parties then and certainly not today.

By all means, do what you want to your car. Just don't post on a discussion forum about your choices and expect everyone to agree that your choices are the only way to go and to cheer you on.

I started this thread because I know that some people, like myself, appreciate the vintage 911s, not to start a argument, not for the cheap whores who bastardizes Porsche 911s, you guys have your own thread. Having been involved, way back, helping a friend who built a stupid horsepower SC, and was breaking transmissions (I am going back to when no one had publicly admitted it, and I have pictures and posts to prove that) supplying him with a 993 6 speed while he fabricated everything to make it work.
Yes, is an expensive upgrade, but some of our projects have been regularl G50 upgrades (Patrick Motors sports did them, again, can be found on this forum).
Not everyone wants a cheap slut, to devalue their 911s:
You guys that do, more power to you, but this thread wasn’t created for you.

Next time my wife puts a drama tv series on in the evening after the kids go to bed, I'm just going to pull this thread up and see what's new.

So what I gather, spending a lot on something that requires completely cutting up your car to fit (It's alright, because its for Porsche parts), it's okay. Spending even more on something that doesn't require cutting up your car, that is 0% Porsche, it's also okay. Spending far far less on something that potentially only requires a ~2 inch hole in the trans hump and a exposed linkage bar, definitely not okay. So, if you mod a 911, better spend a lot to be accepted by purist goobers.

You can do whatever you want to YOUR 911, as YOU own. And you really should not care what others think. Yet you do....

Come on guys, this thread was started specifically by the OP to discuss this potential gearbox upgrade for those who are interested in a box that could potentially be a true non invasive [mostly] upgrade to the 915, I am sure he didn't expect it to get the negativity its now receiving by a few here who may or may not have legitimate reasons for going off on a tangent, by doing so; its taking this thread somewhere I am sure the OP didn't intend it to go.
Ant.

I may be in the minority, but I don't look at these cars as investments, I look at them as experiences. Driving, working on them, sharing them with others, etc... I'm personally ok with the 915, but it is the least satisfying gearbox I've ever manipulated and the aspect I enjoy the least about these cars. If I could change that experience (my preference would be a G96 or G97 vice a sequential) and it's not financially prohibitive, I would do it in a heartbeat.

To each his own!

Agreed!

And it’s 40grand!

Ok lets go back to the OP,s thoughts. It looks like a great transmission. pretty pricey! I guess if I were racing my car it would be ok.

[stownsen914]

It’s pretty easy to drop half that or more on a 915 properly built for racing, or converting to a G50. When you consider that, the price isn’t outrageous.

[Evan Fullerton]

G50 swap these days with a rebuild and LSD and WEVO shifter and new axles and new pedal box and in my case electric speedo conversion…….. it’s well over $20k in parts and a LOT of labor.

If this thing is $30k, bolts in, and will hold 500hp like a G50….. it’s a great option for dumb people like me that want GT3 performance in an old car.

Does anyone have any insight as to how the Tuthill 911k 6spd 915 works? He took out the reverse gear and added some oddball reverse system. I assume it's somewhat similar to this box?

I've been looking for this answer for months and have come up with nothing.
Hoping there is someone out there that knows how it works.
