If you decide to go bigger with the turbo do the 19t or 20t conversion. Easiest thing to do. I only spend $360 turbo my 13t into a 19t w/11 blade turbine wheel. I can't wait until tune and throw everything in.Well by the looks of it you are much closer than me to that goal. My goal is more of a wish, and my plans of getting a 16t and a tune are still in their earliest stages. I'm still bone stock right now, working on Stage 0.
Just remember that only a 13/16/18T can be made into a 19T. My 2.5T had a 14T which isn't interchangeable (the hotside is smaller and won't fit) so you'll have to get the whole turbo. Still it's only $20 more than a 16T which is a large reason I went for the bigger upgrade off the bat. I did consider a 16T before my swap, but figured I wouldn't want to pay and do the work to swap in a 16T and then a 19T down the road.Thanks for the heads up! I will look into that.
