Why no just take a standard 915-930 tranny and flip it up side down? This should take the hassels out of flipping the ring gear, you would have to come up with pump and a shift linkage though?
I dont know enough about it yet but I am looking into it really closely. I talked to a guy the other day that told me to call Scott at Renegade Hybrids and talk to him about it. From what he said, it is very expensive to convert a 930 trans to work correctly with a V8 car. He said once you are done though it would last for ever and be good up to about 700 HP. The cost he said was close to 10k for the transmission and conversion. There has to be a less expensive route but without more research, I dont know yet. I would suggest calling Scott at Renegade and talking to him about it. He also said that he has been running a RH converted 901 on his LS1 for 4 years without any problems and the cost for that transmission was only around 2500. Maybe a better option if you are just running a street car.
Brad has or had an adaptor plate for running an upside 930 box.... (I think???)
I want the baddest street car known to man yet I have to be concerned everytime I drop the hammer whether or not the tranny will go up in smoke when those big bad 335-40/ZR17s hook up.
I will definiteley run either a 930 or a 915 box, but why not maybe a G50 or something like that? Is that a better option? I have no interest in running a 901 gear box, will never be able to handle my driving with a 600hp V8. 901s are for budget swaps or 4 cylinders.
The adapter is not the problem but I was wondering if anyone has ever done it.
While we're talking about V8 trannies. how about these?

This looks surprisingly like my 944 trans.

From Pors-chev.com
Installed a 915 in place of a 901 in a clients v8 car. Custom shift cable assembly install is fairly simple. A WEVO unit would be better if it becomes available. The cost of the 915 will be upwards of 7-8K. It will still have a poor 2nd gear ratio for track use (turn 3a & 3b @ Pacific Raceway). Lar
Please post the pics. I would like to see them.
The car that is in the early design stages is a LS2 powered 914 with a dual a-arm front and rear suspension. The chassis that I am starting with is all rusty so I am going to cut the front and rear halves off the car and build subframes that bolt on. The engine and tranny and rear suspension will be housed in tubular subframe that can be removed or modified as necessary. I have the liberty of using any transaxle I want because I am starting from a blank sheet.
This winter will be spent fixing my current four cylinder car, finishing the turbo honda and doing some design work with the chassis and suspension for V8 car. I hope to start cutting some tubes in the spring.
LS2 ? At GM we had a LS1 and LS6. We had LT1, LT4, and the brain damaging LT5. I do not recall a LS2.
Oh please, can you tell me where to get info on the differences between these engines? GM for dummies... Even though we're building a standard SBC that I'm familiar with, I still am in the dark on the newer ones.
Sorry to get off track, I'm very interested in Trans options and if any of the ones I posted will work.
Thanks,
Dan
Your local Chevy or speed shop should have the Chevrolet Power & GM Performance Parts books. These will give you a ton of info however they are weak on LT4 & 5 info.
I'm just looking for general info. Like what year they were built, when the blocks/heads/etc changed.
I just figured there would be a site out there that had that. Haven't found it yet.
Thanks,
Dan
The LS2 is the new version of the LS1. 415 hp, 15lbs lighter than the LS1. Should show up this summer. Not sure if this is just a crate motor or an actual production motor but I read about it a few months ago in Car Craft.
Brett,
Contact Ed Ducey (propicer), he is a partner or something like that for the West Coast built Ultima cars...
I copied this from the official Ultima website:
Hi guys, super lurker turbo Paul here. I have not heard anyone mention the Pantera ZF box as a great alternative to the other gearboxes mounted to a v8 in the 914. Many others and I have gone this root with great success. There are many Pantera's out there with 700, 800, 900HP big and small blocks mated to the ZF living a long life. Because the Pantera was designed to work with the v8 the gear ratios are perfect. As a matter of fact you can get any gear ratio you like. There are also a few v8 powered 914 running the ZF as well. Just my attempt to add to a great discussion.
Regards,
Turbo Paul
So, what $ does a Pantera box go for???
So, what does a decent used 930 box go for anyway? Not with any tricks done...just known good used. And on the same note, whats the cheapest you could get one for? Say, still usable but needs a rebuild. I have a rear engine v8 project in my future, and the tranny is still the missing key, space isn't an issue, so I figure I could go 930, or ??? will need to handle lotsa torque ~400ish...
Thanks,
Tony
oh yea, the ZF is a great choice, if you can afford one: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7911599849&category=33733

I noticed both are claiming brand new, so I'd venture to say that a decent used one is in the 2K range
I buy 930 boxes in this area with LSD's for around 1500$. Normally second gear sync's are toast. It was very popular in our area for shops to yank the 930 box and install 915's so we have them floating around this area.
Scott at RH does not run a 901 box. Hasnt in a few years now. He runs a 930box.
The G50 would be fine if you didnt have to run 20inch wheels/tires with it to get decent ratio's out of it (it isnt that bad.. but.. 17's are almost required)
I like the 930 box. Sure it is more work.. figure 7500-8000k for everything.

Guys,
I have seen a lot of talk about the Getrag 6 speed boxes being used on the european GT40 relica's, as well as the Audi 1E 6 speed box, both mounted to Ford 302's and 351's.... Does anyone happen to know if either of these boxes = the Boxter S box under a different name?
Thom
Tom,
I have seen the Audi box used.. but I have NO pics of it. Can you dig up some pics for us ?? (good seeing you in Texas BTW)
B
Ok,
Lets see if I can do this....
This is the Audi 01E box, supposedly the same as the 968 box, according to this website... http://elektro.cmhnet.org/~charlie/photos/cars/01E/ind3.html
Attached image(s)
Problem with the Porsche box:
NO provision for a starter. It was mounted to the bellhousing up on the engine.
B
I could see the Audi box working... but what about the ratios ??
B
B,
Sent you mail.
-LB
I guess that means I should check my email at home...
B
Brad,
Go here for the ratio's...
http://elektro.cmhnet.org/~charlie/photos/cars/01E/trans.html
And you might find this interesting as well...
http://elektro.cmhnet.org/~charlie/photos/cars/01E/ind2.html
Would cutting a 944 turbo trani and a 901 trani, then splicing the housing from the 901 to the 944 turbo, work Brad? Ehh ehh?
Your back... Glad your back! Have fun? (kiddin, I saw the GT thread...)
I just barely have time to read right now.. you sent it to the right place.
Andrew.. too much work for little return. Look at what that guy went through to have a Boxster box mated to his aircooled 6 cylinder.
B
But its only labor....
I dont know what work he did, I only saw pics that I barely understood.. and a large price.
My 901 wont be very happy with me for very long...
Have a for me B, take it easy.
Andrew
Havent had any beer since Texas...LOL had to drink Miller Lite with my buddies.. one night we stopped at 9 pitchers between 6 of us. I quickly realised how "Lite" the beer was..
B
Ahh the wonders of beer.
So when DID you come back? Fri?
I was physically back at work on Wednesday last week.

From what I have seen it’s a toss up between the Pantera ZF and the Porsche 930, in terms of power handling ability and cost. To have a 930 gearbox modified to work in a 914 ready to install will run you about 9,000 including the cost of the gearbox and you only get 4 gears. The Pantera needs no internal modification to be used in a 914, just need to purchase bell housing to mate to desired motor, and you will have 5 gears for 9,000. My choice was the Pantera ZF.

Turbo Paul.
Here's more comparative info....http://webpages.charter.net/jims80/M6B-GT/Midenginetrans.html

Felix,
Thanks for the links. After reading that I really want to explore the Audi 5000 Transaxle.
Dan,
Glad my late night web surfing helped someone! Some info may be flawed as I know Harry runs gobs of torque through his ZF:
Well if you guys are thinking of trying an Audi 5000 transmission, why not go for an automatic trans from a 5000. Have you ever seen a true automatic in a 914? Think if that as a concept, no more burned up clutches from sitting in traffic. I was thinking about it myself and I have heard it can be done. They have done it to a VW van over here in Santa Ana so why couldnt it be done in a 914 with a V8? I think it would be cool.
With the Audi model 016 gearbox, you will not be able to swap out the right parts from a 951 to get the good ratio's and strengthened parts. The input shaft and first gear are a one piece design, so you're forced to stay with the Audi 1st (3.60:1) which means you don't get the heat treated 951 1st (3.50:1). The 2nd thru 5th ratio's are very close to the same, so no need to swap there. The R&P ratio is where you gain the advantage with the taller geared 951. Though un-substantiated, apparently the differential carrier bearings are larger on the 951 than on the Audi, so they will not swap.......I recalll reading that the 951 racers swap out the R&P for a NA 944 R&P to get a lower ratio, so perhaps there's a chance for interchangeability (Any 951 experts or racers out there that can verify this?). For the cost, I would think it easiest to simply stay with the Audi 016, though the net 5th gear ratio is about the same a a stock 901. Audi 016 model 3U is the only one that has a taller 5th, but was only available in Europe. Good luck.
Andy
Slightly OT here,
Anyone know if you can flip the ring and pinion in the Audi 016 box?
I'm thinking of it for the http://evcl.com/vw/
