Mine seems to be a pretty good turbo..not much lag over the stock..I did have a impellar get chewed up & I was blamed for it from PTE..hell maybe I was the culprit..but the ex side was all great & all around seems to be a very nice turbo..I wish I had went a lil bigger now but I would need a converter for sure..this one runs fine with stock converter but Im sure would really wake up alot with a bigger converter also..
