That kit looks pretty nice (look at the size of the damn turbine!).

Going off the topic a little...
However in my opinion a bi-turbo system would be more effective. You have a smaller turbine that spins up to speed faster at low RPM and then you have the big one kick in once you are up to speed. That somewhat reduces the turbo lag, as opposed to when you just have a one massive turbine installed.
I understand the engine is obviously tuned (prior the DET conversion) but I still would expect a pretty decent lag before the turbine kicks in. What do you thinkg, Cyclemut, wouldn't a bi-turbo be a little more effective in this case?
