Here are some pictures of the .64 A/R T25 that I have now vs the .63 A/R T25 plus turbo housings. You can see clearly that the T25 plus will allow more flow.


















Soon man it's getting warm out now up here in the North East I have new rims and tires going on Friday. I will be making another video soon after that ,and will be posting it up.
