i just put a vj5 turbo on my car everything bolted up except the cooling line no big deal, and the exhuast elbow so i went and got a elbow from a vj11, they also fit the vj5 but doesnt have the cat it with it, i put everything on and the thing that controls the wastgate was hitting the side of the block so i switched it with the one off of my vj14 wich is a little bit smaller, will this afect the wastegate? are the springs in them different? also is the vj5 bigger, smaller, or the same as the vj14? what boost should i be running at with the jv5?
