Mario Posted September 3, 2020 Share Posted September 3, 2020 (edited) Hi guys long time no see but yet not forgotten Has been a long time since last post but promised to share a bit around our 6speed. Last year we got around 1200NM torque on the getrag witha 7675genII on x amount of boost. We found the inputshaftbearing didnt liked that amount of torque and started looking for a box which on paper can hold this amount of torque, and shave off some weight and we didnt want to change out the carbonetic tripple carbon clutch either didnt we want to change out the diff. So lots of things we didnt want to change and spoke with Dan Burkett, maybe some of you have heard from him in the past but he likes to drift his supra long story short we chose the samsonas 6speed, contacted the samsonas europe sales department they sent me through my nearest dealer. discussed the goals and requirements and then our own chosen gearset got fabricated.Certain rpm limit chosen to give a figure on speed per gear. Our revlimit is higher so speed will be higher per gear so this is just to see something. v160 1st: 3.827 76km/hr 2th: 2.360 123km/hr 3th: 1.685 172km/hr 4th: 1.312 221km/hr 5th: 1.000 290km/hr 6th: 0.793 366km/hr Samsonas 1st: 3.000 93km/hr 2th: 2.000 139km/hr 3th: 1.500 186km/hr 4th: 1.190 234km/hr 5th: 0.962 290km/hr 6th: 0.760 367km/hr We choose dropgear 1.040 weight of the box is around 38kg ex 2ltrs of oil Box can handle 1400+nm torque lee at Srd did everything for us from installation and fixing issues to get this working properly on our mkiv platform. J3 bellhousing and adapterplate was required including getting the propshaft in and some other small hardware. As a proper gearbox mount needed to be designed and fitted. Along with the gearbox upgrade we finally had room to make some more torque so we decided to go the alcohol route. On e70 and 2,6 bar we pushed 1400 nm torque with 1300bhp. car feels very solid and shifts like a charm its a total beast now last month we tested our new setup in zweibrucken half mile first run for me ever with this box and torque misshifted with the box second run went better hitting revlimiter (300,04kmh)5th gear going over the finish line so we had room for more speed in 5th Contacted Lee and he remote gave us a bit more rpm so we took it for another run and easy 303,09kmh now need to grow some balls and use the flat shift system as this 303,09kmh was on easy shifting car can go faster in current state.

Mario Posted September 3, 2020 Author Share Posted September 3, 2020 Wow ..impressive!! May I ask what the cost of the new gearbox was? :o yes as its no secret the universal 6 speed rwd type samsonas can be ordered new for around 5500euro if remember correctly The shifter is another 500 euro. You will need the adapter plate which is another 500-600 euro. Then all the labour and propshaft etc The Full sequential version is around 10-11K, but anyhow if anything breaks parts can be ordered. For actual prices just go and ask at samsonas motorsport. Quote Link to comment Share on other sites More sharing options...
