Oh it's still happening, just trying to get the 1970 Z finished and ready for sale in the spring, when that is gone I'll have some money and space to work on the ///MZ.
I was just looking at this lovely 240Z, http://www.speedhunters.com/2016/02/os-giken-power-americas-exotic-240z/
I'm having a hard time believing those numbers, 376hp, 281 ftlb torque at rear wheels from a 3.3L with carbs.
Granted, you have a team of very talented guys and probably a bottomless budget and I suppose the torque number could be accurate but the hp sounds a bit puffed up.
This engine that I'm using is the same configuration with 3.5L and FI through 6 independent TB and could get near that hp without a turbo.
Rossiz, these pics of the OBX limited slip diff are for you, I had to disassemble it and clean up the hardened on lube they use at the factory, flip the gears 180 degrees and replace the soft cone washers but it's already to install in the R200 diff now.
