Mazworks sells axles for $1,800 that can take the power. Talk to them, as they build 1,000hp S13s for drag racing beatings. As stated above, the rear end isn't nearly as big of an issues as the axles. I am putting down 460rwhp through a KAAZ 1.5 in an S14 differential with Greddy cover, Energy Suspension bushings. No problems for me so far.
