Nice turbo for the price. But there are alot of different things that come into play with turbo's. Different motors can make different whp numbers on that same turbo. If you are going to put that on a honda or another 4cyl. that isn't a bad turbo and you can most likely reach 300whp on a good tune. Anything bigger and your gonna have lag like a mofo. Well if you still have this in a couple weeks I will take it off your hands g/l
