Sorry I meant GXP...Ive been reading up on the top swap and Ive read that you have to evenually have to swap out the transmition.. Is this true? and my car has 104,000 miles so idk if its worth the money or with doin the top swap ill be pretty much replacing most parts to give me all new seals. Also I wanted to know how much this would cost conpaired to just buying a junkyard gtp engine
