Sorry if this has been covered, but I couldn't find much info comparing the two. Ive been doing some research recently on swapping a CL-S 6 speed into my AV6 and have been seeing that a lot of people opt to swap in a J32 as opposed to keeping the J30, and I'd like to know why? I don't know much about the J32 but isn't the block the same as the J30, and its nothing more than an enlarged stroke giving minimal gains compared to the J30 and compared to the added cost of engine replacement instead of only replacing the transmission? Is the J32 really that much better than the J30?
