*** Available soon - Toy Tuning Uprated Dog Engagement Straight Cut Gear Sets ***


Recommended Posts

Hi all,

As some may know we have been developing dog engagement straight cut gear sets for both the C52 and C56 gearboxes (EP82 GT and EP91 Glanza V). These will provide maximum reliability for those with constant gearbox problems. Starlet 4efte gearboxes are a notorious weak point. They are perfectly good gearboxes when considering a stock car, as soon as you begin to push the limits they begin to ware very quickly.

Whether you have a 200hp Starlet or a 400hp Starlet the box won't last forever and can be very costly to replace with OEM parts, more in fact than our gear sets. If you drive hard then this time scale will be seriously reduced. If you attend regular track days/qtr miles events then you will be well aware of the problems the boxes can cause. We know some of the high HP lads are going through gearboxes on a weekly basis so we hope this will answer your problems! The main advantages of these TT kits will be:

- Straight cut gears to minimise power losses

- Dog Engagement for maximum durability/strength to withstand your punishment!

- Massive increase in shifting/gear changing time aiding accelerator and times

- Options for both short and long ratio pending needs

- Preciously made billet gears made to the highest standard

- Involute gear tooth profiles optimised for each gear

- Precise case hardening and shot peening

- Complete kits with gears, hubs, shafts, fork, final drive and a direct fit to the C52/C56 Box

- Specifically designed for the Starlets not a borrowed/copied design

- Long term piece of mind for those replacing gearboxes after every event!

We have designed two types of gear set, one short ratio gear set designed for the less powerful Starlets who need quicker acceleration for track days with a greater torque band to get you ahead of the field (3rd, 4th and 5th), without breaking gears from excessive hard driving. These are ideal for anyone running sub 250hp but each application will be different pending needs. The second gear set is a longer ratio set designed for the higher HP lads running from 250hp to 500hp. Traction, wheel spin, constant gear changing and gear damage can be a major problem when running high HP especially on the qtr mile/circuit. Fourth gear will see up to 160mph meaning you won't be shifting through the finish line aiding times immensely. Another key feature is gear changing time, these gear sets will allow for rapid shifting increasing acceleration tremedously. The strength and durability of these gears is top of the line meaning you can finally remove the notorious weak point.

Each set will include 1st - 4th Dog Engagement Billet Straight Cut Gears which will also include the crown wheel and pinion. For 5th gear we can supply a Syncro Billet gear or a Dog Engagement Billet. We will be using a Syncro Billet 5th gear to give you some idea on what is needed, we don't feel the need for a dog 5th but it's totally up to you. Features of our gear sets include billet material of the highest quality, the latest involute gear tooth profiles optimised for each gear, turning and gear cutting on state of the art and sophisticated Mori Seiki/Liebherr CNC machines and very precise case hardening and shot peening as part of our normal production process.

To give you an idea we have listed the terminal speeds of both sets, obviously this will differ slightly pending your own car/setup but this will give you a good idea. If you require exact ratios please ask, we would rather not post them here to avoid copying as these setups are very unique and have taken a long time:

Short Ratio:

1ST - 53.72 MPH

2ND - 72.04 MPH

3RD - 95.33 MPH

4TH - 114.11 MPH

5TH - 133.62 MPH

Long Ratio:

1ST - 50.43 MPH

2ND - 78.96 MPH

3RD - 115.80 MPH

4TH - 161.17 MPH

5TH - 183.93 MPH

Obviously this will differ depending on RPM limit, tire size, differential ratio etc but that will give you a good idea on what can be achieved. We will be doing a group buy on these with around a 10% saving. We are hoping to keep these under £2900.00 inc VAT, the Quaife Dog Engagement sets for the Corolla (not available for Starlets) are just over £3500.00 inc VAT and based on an exchange basis where as there are new sets, we don't require your box. These are also a direct fit and won't need modifications to the housing like the Quaife kits. These offer a nice saving for the same durability and benefits, with the added advantage with being specific for the Starlets.

We will let you know how it all goes and start a GB as soon as we can as I know a few of you have been desperate for these. Below is a picture of the actual gear set and we will get some more on the way very soon.

Best Regards,

Toby

Christ! ToyTuning, thats going back a few years now. My current GT is still rocking an old sticker of his lol.

As for the gearbox question... the E153 MR2 Turbo gearbox is quite strong, getting one to fit into a starlet isnt gonna be straight forward though..
