![]() The car feels so fast with these new gearbox ratios, the difference is astonishing, rapid fire gear changes and faster response due to the gear ratios being stacked closer together. Be aware that the 6 speed cars use a 3.2 diff and the auto cars have a 3.7 ratio as standard so you might want to change the diff ratio if its an auto. So as you can see the 7 speed gearbox has very tightly stacked ratios and longer 7th gear compared to the 6th gear of the V160 for cruising. The gear ratios of the 7 speed gearbox are: The transmission tunnel needs minimal work to clear the gearbox bell housing, small adjustments with a tapping tool! And don’t forget after the conversion you will have your 6 speed gearbox and conversion parts to sell and as you are probably aware they are worth a lot of money with prices on the up. Manual owners will enjoy this too, gone will be the slow clunky gear changes offered by the V160/1 gearbox. You can cruise around in automatic mode just as you would with an autobox but then switch it into manual to change gear with the gear lever or flappy paddles. For those with a tuned Supra running the autobox our DCT gearbox conversion will be a revelation, no more slush box with no control over the gearbox, no more waiting for upshifts and less power loss as there is no torque converter sapping it. We see this conversion as a major step forward bringing the Supra right up to date with latest technology transmission. So far in testing we’ve pushed the gearbox with stock clutches to 650 lb/ft torque, plenty for most people, it may take more but we haven’t tested beyond this yet. We’ve also fitted carbon paddle shifts to the steering wheel so you never have to take your hands off the wheel to change gear, flick the right paddle to change up and the left one to change down. The throttle pedal has to be changed to a drive by wire type too, the pedal we use bolts directly into a Supra, all available as part of the kit. This bolts directly to the stock manifold with a custom made billet aluminium adaptor. We’ve also fitted a drive by wire throttle using a Bosch item that’s normally found on a Porsche 996 turbo. The conversion comes with a new mount for the gearbox which allows it to bolt onto the stock location and uses a new propshaft flange to bolt directly to a stock Supra auto propshaft too, (manual propshaft does not fit). The gearbox is attached to the engine with a custom made billet flywheel and billet aluminium adaptor plate. Clutches are immersed in fluid so don’t wear as fast as normal clutches. Launch control, this can’t be done on auto cars.Ħ. Better fuel economy and less power loss than any auto gearbox as its direct drive, no power sapping torque converter.ĥ. Throttle blipping on downshifts, this sounds amazing!Ĥ. Then in manual mode you can use the flappy paddles on the steering wheel.ģ. So if you want to just poodle around in auto mode it drives as smooth as a normal automatic. Imagine if you’re on a race track,how much faster it would be on a lap.Ģ. The DCT version of the M3 is 0.2 seconds faster from 0-60 over the manual version, thats just one gearchange. This in turn massively reduces acceleration times improving the cars performance. Super fast gearchanges, the 7 speed Getrag gearbox we are using changes gear in 80 milliseconds. And are now being used in main stream cars too like Audi, BMW, VW, Renault, etc.ġ. The DCT (dual clutch transmission) gearboxes have been steadily taking over from the manual gearboxes over the years, most of the supercar manufacturers use them in their cars these days, Ferrari, Lamborghini, Porsche, McLaren, etc all use DCT gearboxes. We were the first company in the world to make a DCT 7 Speed gearbox conversion kit for the Supra JZA80 and now we’ve taken it a step further using the latest Getrag 7 Speed DCT gearbox as fitted to the BMW F8X M3/M4.
