Fair enough.
I am almost at the point of running what I have until the little sucker (no pun intended) lets go. I bought this car to experiment with biodiesel and Vegetable oil a couple of years ago. It has already more than paid for itself in fuel savings. I do still run the stock air filter because it is probably more than adequate. So I really wouldn't have any problem with shrapnel in the intake charge. That compressor wheel did look awfully dirty, especially for one with water being injected into it. Even my diesel turbo compressor is cleaner than that.

I am in the process of getting my Cosworth turbo 2 liter project together, and am considering water injection INSTEAD of intercooling. I have to do some more seaching on the forum, but so far, it seems feasible.

Thanks
