if u want to spend the 2 k wisely i would go with a 3.0 find a used one. ask around on the board. and get it done. uwould need a ecu chiped programed too. plus injectors, gaskets, and some other stuff.
for everything if u do most of the work yourself it would range from 2k to 2.5k
these numbers might not be correct, so feel free to correct me.
