i can get a ls vtec motor for cheap from some guy. he had gsr pistons in there and just swapped them out for itr. my question is, what will i need to do to the block that will make it reliable and not blow?? nothing was done to the block except the pistons. how much will the addictional things will cost me to do?? will i need block giddle, squrter, ect.. i dont want to spend a fortune.
