no one needs differentials anyways
NA to TD in less then a week, that's impressive
it is open diff, if that was sarcasm, that diff is a Dana 30, i have 300hp flowing through one in my other car, it blows up transmissions left and right but that diff is good to 400+whp.
yeah, the actual turbocharging part i did in two afternoons after work, the rest of the time was spent gathering parts.
