Hi, I have a Nissan s14 that I swapped in a 1jzgte vvti with a R154 transmission. I'm putting down 400whp/370tq, but still have the stock open diff with a 4.08 final drive. I'm going to put in a HLSD, but not sure what would be a good final drive. I was thinking of going with a 3.69. All I know, is that my current diff sucks and I can't wait for a LSD. I forgot what it feels like to actually have traction in that car....lol
