If your car has ABS then Integra axles will work fine. Otherwise the spindles are different on the ABS and non-ABS cars. I would say that with the amount of power you're going to be making and limited-slip you really do need some beefed up axles. Driveshaftshop.com has a bunch of assorted "stages" that you can get, the cheapest of which is $300 for a set. If you want really good durability you'll have to pop for the $500 set though.
