RENAULT UN1 3;44 MODEL WITH MODIFIED GEAR SHIFT SHAFT AND ADAPTORS

RENAULT UN1 TYPE

Commonly used in many replica and kit cars since the 1970's the Renault UN1 type gearbox started with the 367 Four speed and the 369 five speed. They were used behind the V6 engines and a good choice for a V6 powered mid engine car.

Later the V6 UN1 gearbox was used in the Delorean, Renault Alpine and GTA. These gearboxes were desirable for conversions due to being stronger and with larger bell housings.

The last UN1 types were the Turbo versions both in V6 and 4 Cylinders. Some other gearboxes had a 3;88 diff and better still for performance the 3;44 diff. It is these gearboxes that have been used in a great number of GT40s Lola T70 Early Ultima's SOme Ferrari McLaren Lamborghini replicas racers projects and specials.

Being from the 1980s they are now quite rare to find in good order and only available rebuilt from specialists such as G T Racing. We usually stock the following though stock does change due to rarity of old units.

UN1 367 four speed 3;88 diff from £1400

UN1 369 five speed with 388 diff From £2000

UN1 V6 Five speed with 3;88 diff From £2250

UN1 21T five speed with 3;44 diff From £2500

All the above are available with LSD such as Quaife ATB at extra cost.

There is also a UN1 upgrade using a much stronger main shaft this can cope with power up to 500hp with similar torque. Extra cost.

We make and supply the special drive shaft adaptors that convert the standard Renault UN1 output shaft to a C V joint flange ready for 100mm or the large 108 mm Joints making drive shaft connection much easier.

AUDI 01E GEARBOX

The Audi 01E gearbox has become a gearbox of choice to some mid engine car builders. Recently used on some GT40 makes using either Ford SMB V8 or Ford Modular V8 and even the later Ford COYOTE V8 engine. This gearbox has been tested by some customers up to 500hp and some even more. In the two wheel version of the 01E the main shaft is a stronger one piece shaft that allows significant amount of power load. NOT ALL AUDI GEARBOXES ARE THE SAME! BE WARNED. They might all look alike but they are not all the same. varying ratios, diff sizes and the amount of given power they take. Only certain types and part numbers are the ones to have.

As the Audi 01E gearbox is quite expensive to purchase new we have been sourcing used units and having them totally stripped cleaned and rebuilt to our spec. We can also fit either the WAVETRAC or QUAIFE LSD or ATB type differentials at the rebuild stage.

SUBARU TO UN1 CONVERSION HOUSING AND SHAFT KIT this is a special housing that fits to front of the un1 gearbox and connects to the Subaru Flat four engine types. This product is new to G T Racing. We can supply the gearbox already modified, diff inverted and ready to fit.

The Subaru conversion was brought about by customers asking if the UN1 gearbox would fit into a VW van. After looking at the Subaru engine I knew it would be a new housing rather than adaptor plate kit. My conversion allows you to use the SUBARU engine flywheel, Starter motor and even the clutch. There are two ways to do the input shaft with either a new Shaft that has SUBARU spline tip which will need fitting internally to the gearbox when rebuilding it, or to leave the UN1 input shaft and use a special spigot bearing in the crank and a new uprated clutch plate with UN1 spline centre. The overall costs work out the same.
