I recently purchased a 91 240sx hatch shell and am building it. I plan on it having about 400-500 hp. I want a very reliable conversion hub and plan on doing a brake swap as well. I found a set of 4 conversion hubs front and back from isis (now they are called isr performance) for about $370. They say they have oe bearings pre pressed. They are being sold from enjuku racing which looks like a reliable site. Would these be reliable and be able to handle the power im trying to get? Has anybody used these before?
Thanks!

The "Now Called ISR" wheel hubs will work ok, they are your typical taiwanese brand, so nothing really bad about the wheel hubs. You only need to buy the fronts, because you can get brand new S14 or Z32 N/A rear hubs and they bolt right on for the rear of the S13. That way you are getting everything OEM. It is more convenient to get the whole package from "ISR" though, ha ha.

Thank for the advice!
