don't convert your your 14b to a 16g, it's not worth it, with the cost of a rebuild, 16g wheel and balance it's not worth the trouble, not to mention you would be sportin a 6cm housing which sucks. if you're going to upgrade get an evo 16g atleast. you don't wanna take baby steps with turbos like going from a 14b just to a 16g unless u get a small 16g for crazy cheap or something. this is just in my opinion, also i read jerry saying the rebuilt turbos tent to fail often. also fuel management is key. and RECIRCULATE you BOV!!! lol jfwy
