I recently discovered I need spend yet more money on this project I have become very familiar with. The new things I found I have to upgrade are of course the differential and the half shafts to turbo specs. My engine/tranny/driveshaft are all s5 j-spec. However, my stock NA diff/half shafts are s4. My question: Will the turbo differential from an FD along with the half shafts bolt up to my drive shaft and under body with no problems? I mean will this be a direct swap without modification? Also will I have to get hubs so the half shafts fit? Need info

 

just get the t2 half shafts and run a s4 or 5 diff from a turbo car, thoughs bolt right in where fd parts by no means bolt in and reqire a **** house full of machining and fabrication.
