Any update ? Just curious how it will end up.
I still think even the later Nissan CD009 edition 6 speed trans should be kept under 700lbs of torque...around 800-900hp depends on the power setup of each car.
The R154 has been in the global automotive life for exactly 3 decades and has proven it's self as far as power level. A healthy oem stock,properly working,around 100-150k miles, with Redline MT90 juice inside, and the proper clutch kit will hold 650-700lbs of torque....and all that, under the heavy mk3 Supra chassis!
We all know a performance company used the CD009 6 speed and boosted 1000hp with it...but that's old news for some mk3's with the R154, and to mention some of the 1000hp mk3s had the long stroke big torque 7M engine to boost the 4 digit amount of horsepower. So, don't question the today's price of an old used R transmission which is around $2000+.
Anyway, I would love to see how the Nissan 6 speed gearbox is gonna move the mk3 tank! Don't forget people that the Z370 chassis with the later more durable CD009 transmission weights 3230lbs around 300lbs lighter than the mk3.
I went with the V160. I just finished my swap and did it 100% properly and everything works like oem. Of course it reached the $8000 mark with everything.
$5000 the used V160, $1200 the used HKS triple clutch kit, $600 the JZA80 TT V160/JZA70 TT R154 hybrid customized two piece driveshaft retaining the (new oem) mk3 center bearing and mk4 mid bearing shaft spline, $200 a modified R154 transmission crossmember , and another $1000 for misc. stuff like new clutch hub bearing kit, new V160 shifter, new boot rubbers and leather trim, shifter knob , custom speedometer ODM unit to make the oem mk3 speedometer work properly, and custom exterior hall sensor ring for the ABS sensor, etc. Last , in the making...the lower rear differential 3.5 ring and pinion with a rebuilt LSD and diff in general. And of course we can go 'lower' by increasing the tire/wheel diameter. I think I will reach the 3.2-3.3 mark with my setup..hopefully!
Best setup would be a V160 with 3.55 rear diff and 285-40/18" , where you can cruise at 3000 rpms in 6th gear with 87mph (139km/h) actual speed,while the speedo gauge will indicate slightly more.
