8225 BP = USD$12,874

If I were popping that in an Esprit, may as well put a V8 on it too - the crate V8 is probably cheaper than the transmission BWAHAHAHA!

Any comments?
I must be too old - those prices look obscene ($15-20K). The lowest one was $10K. Interesting that they seem more dune buggy-oriented (probably due to the VW legacy).

That Quaife transmission on eBay must be in the same league, but didn't realize they did transmissions too.

My bud from AU suggested 915 tranny, which is not that expensive in US.
Can be found on 1972-1983 model 911 cars
w/ 5 speed, 8/31 ring & pinion.
Same gear ratios as 1975 915-40, 1976 915-44, 1977 915-60 & 915-61, 911 transmissions!

Gear ratios:
1=11/35
2=18/33
3=23/29
4=26/26
5=28/23

more info here: http://californiamotorsports.net/pag...-specification

The 915 gearbox was derived from the 916 unit which had been built for competition in the 908 racer.The 915 made its first appearance on a 911 in '72 with the 2.4 liter engine which had 8% more torque than the previous 2.2. The 915 is a fine competition gearbox; light fast and accessible. Just look at it's racing record - all the 911's successes from the seventies and eighties.

$13,000+ for a transaxle!



The more I look at these prices the more I realize how lucky I was to get a UN1 during one of the old Lotus factory sales.

Quick update here on this one....

So I have my SBF drive train ready....Ford 331 stroker with aluminum heads and forged internals, aluminum intake with a Holley (for now), stainless steel shorty (block hugger) headers....all mated to a Audi 016 with a porsche 944 LSD installed by way of a Kennedy adapter plate.

Next step is to remove the Lotus engine and transaxle....

Wow!

How much torque are you shooting for? Have you considered 01e ? Which one is shorter?

P.S.
Any Audi 5000 from 84-87 two wheel drive trans are all the same.found out, the 5000s and 5000s turbo are the exact same transmissions. I talked to a local performance transmission shop and they feel the audi 5000s transmission if cared for is good for about 450 to 500 hp.
interesting thing is that they used the Audi 5000 S Turbo transmission. As it comes from a front wheel drive you do not have to flip the diff over
The Audi 5000 transmission that the 5000s and 5000cs have different final drives. s=4.11:1 and cs=3.89:1
The 016 boxes have the selector shaft on the left hand side, all other boxes have the shaft in line out of the back of the box.. The CV joints used on most (UK) GT40 replicas are from the Ford Granada and the output shafts on the Audi type 013 transaxle have mountings to suit. The Audi type 016 has output flanges to suit similar but slightly larger diameter CV joints which could be adapted for use with the smaller CV's if necessary or better still to use as standard with larger diameter drive shafts.

Yes, the 016's are all the same except for ratios. There are certain 016's which have much better ratios than others. The one I have is coded AAZ which is a pretty good ratio set.

Yes, it's a beefy transaxle, particularly with an LSD installed. My 331 SBF has about 400 hp and 400 tq. It should be fine so long as there's no drop clutch burn out starts.

Yes, selector shaft is on the left. I have a shifter mechanism from a GT40 replica which uses cable shift so I'll have to run cables to the left of the 016. Shouldn't be too tough.

I'll be using 930 porsche CVs and modified axles - should be plenty tough enough. The 930 CV's have a good range of useable motion.

I'll keep things posted here as the project moves forward

Thank you Cliff,

FINALLY, a viable alternative!

Isn't your 5-th too tall on AZZ? Could it be converted to 0.64 [from 2U,6U,3U,APN,APP,4V,5V]? I assume that the gears are interchangeable?

What are you going to do about the clutch?
Check this discussion:
Uprated Clutch good for 300+bhp - Gearchange/Gearbox/Clutch - The Lotus Forums

Considering that you'll need a Kennedy eng. plate to bolt the tranny to the engine, you may "make" some additional space available Twin Clutch into an S4S? - Gearchange/Gearbox/Clutch - The Lotus Forums
.

Have you considered 01e ? http://advancedautomotion.com/shop/p...products_id/29
It seems to have better 1st/2nd ratios

What about a feasibility of swapping Audi 01E transaxle into Esprit?

I was told they can handle up to 600 ft lbs.

I assume the DriveShaft Shop can make custom axles out of forged 300M.

Looks like these guys make adapter plates for them http://www.kitcarchassis.com/adapter-plates.php
