sizler--
I would recommend getting the hara or surikarn version...they come with all of the updated bulkheads which mean you won't have to grind anything and they are reenforced in certain areas.
Also, the surikarn/hara kits come with the locked center pulley while the standard cyclone kit only comes with a center one way... one less part to have to find and buy.
Regardless of which one you buy you're gonna have to buy a front diff....but I highly recommend the newer style aluminum diffs with blades!
