Happy Customer
This turbo is made for a fast races. Ideal for drag racers who want to make obscene power levels with reasonable spool. I had some problems installing it, but it all grades with power you have got. CARiD offers an unbeatable price, so i will return soon.

Good Turbo.
This is a very good turbo. It was easy to install and it show nice dino test results. Can't wait to see it on a track. It's big enough to handle a lot of power and boost, yet it still lights really quick.
