Six Speed 915!

I'm a bit surprised at how some have responded to a simple discussion in this thread. Unfortunate.

If you want more information you can email them and they will provide you a 20 page document as well as a ratio chart.

Is the price in that 20 page document? Give me a g50 style gear set crammed into a 915 form factor for 15k and I think you'd sell them all day long.

You could just drop them in without having to mod the torsion bar for pre 87 cars. I guess you can already sort of do that with mods to the 915. Would just be nice to have that top gear.

Kennedy engineering makes an adapter plate...

100%, they would have to keep up with demand.

Seems subarugears has an offering too. Just advertised as a adapter and flywheel for a subaru box to a Porsche Flat 6 2.7, so as to which 2.7 they are talking about, who knows.

Looks like someone on ebay makes a 911 shifter and linkage adapter bar too for the subarus 12'clock connection instead of the 915's 6'clock position. I know nothing else about it either.

my problem with 915's and its variants is it/they are not very strong. maybe this new albins offering is different? cost? because of foresaid problems im currently having cms build a g96 6 speed gt2 variant for my project. much stonger but very very expensive. so if this 915 was stronger and affordable/under 15-20g, then it might be viable for some.

On my blasphemy build, I have a G 96 mated to the Subaru flat six, but it is really large and requires adapting the chassis to fit it.

Straight cut gears are stronger than helical cut. So I would expect the Albins to support 350 hp if there is an external cooling option

The price was not included but I can't imagine they're $15k. I replied to the email and asked the price. I'll report back.

Thanks! I'll be browsing the "Used Parts" classifieds over the next few years hoping one pops up!

Stupid price. They won't sell many.

My brother put a NEW Richmond Gear 5-speed transmission into his 1961 Studebaker Hawk. It was less than $3000. Yeah, I know, it has the R&P in it too, which costs more, but not 10 times the cost. And it shifts better than any air-cooled Porsche tranny.

Another comparison: A complete Ricardo transaxle for a FordGT is around $13,000, and that has 1000+HP capacity.

Back to day dreaming...

Ok, priced a 993 six speed lately, then add the cost to rebuild to as new, with Guard gears, then add in the cost of the parts needed for the swap and lastly the modifications required to use in a 915 chassis. Even if you have the skill to do the work yourself, by the time you calculate everything to make it a drop in like the one posted.

I've been offered $26k for my 993 g50/30 which was used in the 993 Cup and 993RSR

Exactly, add the cost of freshening it up and the price is over the cost of this, and you still need more parts and modifications

Oh Bill, your purist is showing. You could just say, “I hate Suby stuff and don’t want it talked about in my forum!” It’s okay—we’d still massively respect you, your experience, your position, and your opinion. Everyone’s entitled to one. That way, we could all just move on and keep talking about Porsche 911s and all the cool things we can do with them.

This thread started with a community member posting about a non-Porsche part—a 6-speed replacement/upgrade/modification for the factory Porsche 915 transmission. It’s aimed at racers and performance drivers. Naturally, some questions came up, and it seemed like no one had answers.

So, I chimed in with my direct and topically relevant experience. I’ve worked with a non-Porsche 6-speed part geared toward racers and performance drivers which is a replacement/upgrade/modification for the factory Porsche 915 transmission. I’ve personally replaced a 915 with this setup in an ‘86 Targa and bolted it to 930 axles. Neither transmission in this case is factory or numbers-matching, but both serve performance-oriented Porsche owners as 915 replacements.

Oh, and here’s the fun part: I checked my Kennedy plate from another project of mine, and surprise—it works both ways. So, not only is what I’m discussing relevant to the original post, but this alternative part is a replacement for the 915, the G50, and even the 901. Also, it's capable of ~800ftlbs/~800hp in an AWD car...

Since posting, my comment has sparked exactly the kind of relevant discourse forums are meant for, like this from WonkoTheSane:

“I think having a Subaru box mated to an air-cooled engine would be more of a game changer than this cool piece... Being able to easily and affordably service a transaxle that could hold a bit more abuse than a 915 sounds sweet.”

Or this from Rodsrsr:

“I think the Subi gearbox swap sounds interesting and related to the topic. The people interested in the Albins gearbox are interested in a ‘solution,’ not necessarily that specific box, so the Subi gearbox is related as another alternative solution.”

These are the kinds of discussions that add value to the community. And yes @WonkoTheSane, I’m working directly with Subarugears on this project—they’re the leaders in reversing transmissions for applications like this, with years of racing expertise in road, track, and rally settings.

Now, Bill, clutch the pearls if you must, but let’s not pretend people only want to talk about numbers-matching or Sonderwerks SKUs in this forum. Porsche enthusiasts enjoy exploring cool, innovative ideas—and sharing them with others.

Finally, I’d like to address your comment:

“Just love the trolls that try to make a thread all about their non-related projects.”

If you’d taken a moment to read the posts and engage with the discussion before letting your purist instincts take over, you’d see that my contributions are exactly, specifically, and topically related.

I do have one more question for you Bill... what's the name of my company, how much am I selling this thing for and how can you get one? Right... you still can't answer those questions... because I didn't "Self-Promote" my company or suggest that I have products for sale, or share a URL to learn more. Just my personal experience replacing a 915 with a non-Porsche 6spd race ready transmission. You call me a troll, but I don't think that word means what you think it means...



Shall we carry on with the discussion, or would you prefer to uphold the illusion of purist law and order?

I'll speak for myself though I bet many would share my take on this, I would also prefer this thread to be focused on that shiny piece of 915 looking bling that our beloved OP posted instead of all 6 speed 915 replacement projects out there otherwise it is just too much clutter and I, for one, am already lost and confused as to what is being discussed. Off topic IOW.

Perhaps change the title to "6 speed 915 clone" or something ? I think that's the key difference this being a ground up redo instead of a transplant.

I would kind of like to keep this thread on track also. I have read the other thread about the Subaru stuff it's cool, But I click on this thread to read about this thread. It seems by now we all could of handled this a little more like adults but! I think one of us should make the 915 more bullet proof, yep I have one like most hard to get into second. I don't think Bill is a purist with completely hot rodded cars. I have a 3.6 in my sc. I have been looking at a later 997 trans to put in so this is why I am interested in this thread. Moral of the story start another thread, why argue? It only sucks when a thread gets to this point.

[jmd88]

So about this stunning piece of cnc work. I’m curious if they’ll continue to manufacture the entire thing using cnc. The epic bell housing as a single block of aluminum sculpted using cnc (super expensive and passes cost to the customer) could be converted to a sand cast unit without significant cost. Then you’d just have finishing cnc vs auguring out ~50lbs of aluminum. What I think I see is a cleaver separation of the bell housing which would allow a new bell housing to be put in place if this 915 based unit maybe g50 housing for instance. Further I’m curious about the ability leverage off the shelf diff units.

Great thread. 5 stars. Highly recommend.

Thread had so much potential until Bill’s whinging began. Don’t like a particular comment? Scroll on by instead of fanning the flames, imo. Sorry to see your thread trashed, Byron.
