Funny thing is I am not sure where to go from here. My original goal was a built 2.5 with 300kw + at the wheels. I have a good set up ready to go in, which I was thinking about whacking a GTX3582 on. I now realise that is going to blow my goals out of the water. So, right now I am leaning towards trying for 300kw on a stock motor. That will involve improved boost control in the form of wastegate mods, and bigger injectors again. The problem that then arises is running 24 + psi through a stock open deck motor is only going to result in the heads lifting.
As for this turbo (20g-xtr) on a 2.5, I was concerned that it would choke down as it is an 8cm rear housing with a 56mm exhaust wheel. As you can see from the 289kw run the opposite is happening, in that the wastegate cannot flow enough and boost is actually rising. So, no matter what happens next, an external gate will be going onto the up pipe.
Future plan? The built 2.5 with this turbo, aim for 260 odd on 98 and 310+ on e85.
I think we have asked enough of the stock motor for now.
Ian, you haven't answered the question we all want to know: how does she drive?
