ok so i want to do a turbo 2 swap on my 4 lug rx7 someone told me that i dont need to swap out the the rear end when doing the swap, so does that mean that turbo 2 trany will fit on to the stock drive shaft?
cuz i just got some sick *** rims and i would hate to get rid of them to get five lugs,

also can u fit lsd diff without having to convert to 5 lug?

 

You can get a driveshaft adapter here: http://www.mazdatrix.com/g9.htm

Yes you can stick the TII diff into the 4 lug hubs, but with the extra power you really need extra braking performance.

 

the diff is interchangable as long as you go NA to NA lsd... if you swap a turbo lsd, youll need the axles as well.

and its a broken record, but your much much better off swapping to a full turbo drivetrain..much stronger parts
