So heres the deal. My truck needs a new turbo and I have a WH1E 18cm laying around thats new minus the compressor side. How would this thing behave if I slapped my 56mm wheel on. I've done lots of experimenting and I get the best mileage with the 56mm. I know the H1E has a bigger turbine wheel and a 4" outlet so it should flow better. What are your opinions on this?
