Hewland, modified 930/915, Mendeola, or ZF are not "cost prohibitive" (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)
ZF soon to be tested with 700 + hp, talk about rare European boxes. One or two suppliers who set their own prices. $500 was a deal "before" they were desireable. Renault: Not readily available in the states...hundreds of them used in GT40 and other race replicas. You can still find used for a few hundred or rebuilt for $1500 in UK and Germany. If a UK supplier can ship them cheaply you can have a 5 speed gearbox comparable to a 915 made for mid-engine. See pic attached. A $5k Lotus new gear upgrade will get you to 500hp and cost less than the high end boxes. Audi: No one has adapted a manual yet but they are being considered in Europe and Australia to replace the out of production Renaults. 901: my last survey had a few running 350-400hp with a stock 901, makes great economical sense if you don't mind operating at it's limits. The tall gearing and plate mods add a couple thousand to the price. BTW, Alpha, check my signature link on tall geared 901 Boxster: Alan makes a good case considering the availability and reasonable price. Still no adapters on the market so you need to be a fabricator type. Here's a response from a guys who is selling a Boxster 5 speed he originally purchased for a V8 application:
I am still awaiting the identity of this "Porsche transmission guy in CA"... If you want to consider transverse, check out the Fiero or MR2 V8 conversion sites... Attached thumbnail(s) |

Anyone think of using a flipped early 944 trans? gearing is probably the same as a 915... plug the breather and fabricate a shifter bar...

944 turbo trani.. ya...
No provision for a starter... Bellhousing doesnt have room for a clutch assembly... Its made to use a driveshaft. clutch and everything is on the engine end. but its something I would like to use..... 944 turbo gears are perfect for a v8. nice and long, and the trani holds 400hp+ why would you have to flip it? it spins the right direction.. |

That's an Audi transmission, the early ones do have a starter area. No need to flip. |

No adapters for the early Boxster/Audi 5 speed. The adapter plate for an Audi 016 is real close however. As I recall, one of the starter bolt holes and I think one other trans bolt hole doesn't line up but the rest do. I was at Kennedy Eng'g, and held their master tooling plate against it. I think if someone were to bring their Boxster/Audi 5 speed to them, they would probably make you an adapter and subsequently make it available to others'.
Mine isn't quite so simple, as I'm using an LS1 and the Audi/Getrag 01E 6 speed. To start with, the LS1 is too wide to in the crank case area to fit the starter in the transaxle starter pocket using Kennedy's flywheel (which just barely fits the Audi stuff). WTF, Having trouble attaching a pic!!!!!!!!! Andys |

I need it to hold up for at least 30 minutes under power. Would prefer longer. Racing application.

(IMG:http://www.914world.com/bbs2/html/emoticons/agree.gif) or email it to me or someone to post it for you. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) I asked KEP and they didn't seem interested in making the Box plate, time and demand or $$$ will tell... PM me your source for these Audi/Getrag 01E 6 speed (IMG:http://www.914world.com/bbs2/html/emoticons/ph34r.gif) |

you've got all the info right above....what more do you want? someone to hand deliver and install it for you??? (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
oil cooling will help make any of the transmission live a happier life under track conditions |

Felix, the transmission on a 944 is not directly attached to the motor....all that is needed to mate a V8 to the 944 drivetrain is a new bellhousing or an adapter plate........ |

If you want to put a V8 into a car transversely.. go see "Fast Freddy's V8 Conversions" for Fieros....
Then please, please please.. DON'T do that to a 914............. If you build from scratch however.. there are quite a few domestic combinations that would make easy and interesting cars.. Take any of the Cadillac FWD Northstars, or Olds Alero setups... There was very briefly, a Ford SVT V8 Taurus of something like 3 or 4 liters.... |

I can confirm that the ZF Pantera box will sustain 700 + hp\Lbs of torque. Ask me how I know. My twin turbo 914 v8 puts out over 1000hp and 1000 lbs of torque. I have thrashed my ZF with 700hp + as this is the lowest setting my waste gates will allow. I can supply all the non believers with pictures and documentation of other Partera's with well over 500 and 600 HP power plants. All running through the Pantera ZF box. Hell there are more than a few 914 v8 here on 914club that put upwards of 400 HP though the ZF. Best dam box IMO, tone of gears available, five and six speed available. KE gave the Pantera ZF a bad rep with information that was not accurate. Ask any one who has one the ZF boxes. Then you will get the real story. My rant is over. Back to sleeper mode.

Thought you guys might be interested in some developments on the Audi 016 transaxle. For a mid-priced, moderate powere level (400hp or less) trans, this would seem like a viable and appropriately priced option. I'm no transaxle expert, but following the $$ tossed around for converted 915s, 930s, built up 914s, and the plethora of non-porsche options - this Audi box sure looks like it should fit into the picture somewhere!
From the GT40s.com board: http://www.gt40s.com/ubbthreads/showflat.p.../0/page/0#57684 The "news" is a new lower ratio R&P set will soon be available (and under testing now) making this trans better geared for a V8. From my engine speed vs road speed plots, this new ratio spreads the gearing over the 930, with slightly shorter first, and taller 5th. With a 26" tire it runs 2000rpm @70mph. A $4K fully rebuilt trans, with a Quaife (and your core), that sounds to me like a viable option. If it will really support 400hp & 350 ft.lbs reliably, it could be a bargain! Maybe the perfect "mid range" transaxle option? Jeff |
