j_jza80 Posted September 4, 2015 Share Posted September 4, 2015 Any idea how much torque these will take Lee? Wonder how it will compare to a 6 speed swap cost wise? Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted September 4, 2015 Share Posted September 4, 2015 Any idea how much torque these will take Lee? Wonder how it will compare to a 6 speed swap cost wise? Yeah need to know this also before we splash out. Very interested Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2015 Author Share Posted September 4, 2015 Any idea how much torque these will take Lee? Wonder how it will compare to a 6 speed swap cost wise? Not sure what it will take yet but will find out Ryan has pushed the 6 speed quite far already. Quote Link to comment Share on other sites More sharing options...
Glanza_Mike Posted September 4, 2015 Share Posted September 4, 2015 Sounds promising Lee, i'd be interested to here what the box can handle, how it shifts and price etc Also, do you have a dyno print out since the car had all it's work done? I don't believe it was ever posted. Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2015 Author Share Posted September 4, 2015 (edited) The plate and flywheel in position Here is the box, we took off a couple of bits off the side which were just to bolt the loom on. Also one of the mounting holes which was for the Lexus starter as it stuck out a long way and wasn't needed Other than that it fits surprising well in the tunnel No mods to the car needed at all Edited September 4, 2015 by Lee P (see edit history) Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 4, 2015 Share Posted September 4, 2015 Shame to cover that flywheel up I take it a custom prop will be needed? Quote Link to comment Share on other sites More sharing options...

Luxluc Posted September 4, 2015 Share Posted September 4, 2015 That's a real crazy SRD project. WOW. You guys are top Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2015 Author Share Posted September 4, 2015 Another pic of the box before it went in and a nice cutaway pic so you can see the workings We made a spacer to support and locate the torque converter, this will possible be part of the flywheel in future. Gearbox in position, we made a custom mount which will be CNC machined in future. Quote Link to comment Share on other sites More sharing options...
Scott Posted September 4, 2015 Share Posted September 4, 2015 This could be a real game changer. Lack of gears is what lets the flappy auto down for me Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2015 Author Share Posted September 4, 2015 Next fun job for me was wiring We got the plugs and a length of wire with the gearbox which was handy It only has two plugs, one control plug and the gear selector switch The wiring came with the plastic mouldings to bolt the loom to the box which made it a really nice OEM finish Ryan helped me out with a pin out for the control plug to S6 plus I then did some digging and worked out the selector plug.

j_jza80 Posted September 4, 2015 Share Posted September 4, 2015 This could be a real game changer. Lack of gears is what lets the flappy auto down for me Let's wait to see how much these cost I can't imagine there's too many ISF boxes going spare, and I bet they're hideously expensive new Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2015 Author Share Posted September 4, 2015 So final fitted pics, we modified the stock selector arm and that works great. Only needs to go from park to drive as the rest is done on the paddles Front part of the prop modified so this will be a simple exchange part and rear section stays stock. Fits really great in there.

666 Posted September 4, 2015 Share Posted September 4, 2015 Very interesting project! Lee how much torque/hp is the is-f rated for? Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2015 Author Share Posted September 4, 2015 Let's wait to see how much these cost I can't imagine there's too many ISF boxes going spare, and I bet they're hideously expensive new Yeah I haven't checked the price new I dread to think lol... I have two other boxes to hand so will see what the interest is like first. The boxes I have will be around £2000 Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 4, 2015 Share Posted September 4, 2015 So probably a little cheaper than a 6 speed swap, *if* you already have or need a syvecs? Can't wait to see some footage. Will the regular IS 6 speed boxes work with this kit? Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2015 Author Share Posted September 4, 2015 Very interesting project! Lee how much torque/hp is the is-f rated for? Just like the stock supra auto it has a fairly conservative torque rating, the supra box we have reliably run 550ftlb 600hp for some time The 8 speed is rated higher so we expect it will take a fair bit more As with all auto boxes, heat is the key so coolers are a must Will have to see at what point it becomes an issue but I'm Quote Link to comment Share on other sites More sharing options...

Will the regular IS 6 speed boxes work with this kit? By the time you factor in other parts probably more but with most 6 speed conversions running power you also need a decent clutch as well. This is where it will even out and I expect it to be around the same or cheaper Will know once we produce the final versions of the mount and prop Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted September 4, 2015 Share Posted September 4, 2015 Having been lucky enough to see parts of this coming together I have to say I'm very impressed! Seeing the guys work and watching some of the development of this project really does show you just how good they are! Happy to see it all together, as are you I suspect Lee! Oh and that flywheel setup; the pics just don't do it justice! True engineering porn right there! Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted September 6, 2015 Share Posted September 6, 2015 This is just pure genius! Cant wait to see more updates! A real game changer! Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 9, 2015 Author Share Posted September 9, 2015 First drive with the 8 speed conversion Just on Ryan's base calibration at the moment but still drives really good. Full mapping is next week then we can really test it. Tim at JT has updated the toucan firmware so we can now display the 8 gears. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 9, 2015 Share Posted September 9, 2015 Looks awesome What diff are you using? And any idea what the theoretical top speed is with the gearing? This could potentially be a bit of a game changer - much quicker through the gears than a 6 speed or tiptronic, and better motorway fuel economy.
