LSX gets my vote! RB's can be bolt in affair too(good luck getting parts in the U.S when in a pinch). There's a couple 2jz kits floating around. All these options require some type of fabrication ranging from light to heavy. The LSX swap mount's are the swap none nissan engine mounts you can buy off shelf. I'd only go LSX over any of these routes if you're dead set on doing an engine swap. Just a fair warning you'll go through that 5k quick fast & in a hurry on any swap. What's your realistic goals? Anything up to 575-600whp, The VG is more than enough in stock bottom end form. Any where near that power range you wont be getting the best MPG's
