As much as I looooooooooooooove the VQ sound, and the fact it's a shorter length block due to having less cylinders, which means it's more centrally placed in the engine bay, and helps with overall balance. . . the overall cost is crazy. Cost alone is what prevented me from going VQ. The cost of the swap, the cost of the swap components, cost of the ECU anti-theft and tuning were sky high compared to the LS option.
LS is soooooooo cheap, and even if you blow it up you can replace it 2 or 3 times before you even come close to what the VQ swap would cost.
If you're just aiming for 400-500 hp, a simple cam swap is all you'll need
