Ok I have a bunch of questions:
Are you guys equating Knock Reduction with pre-detonation? Because it seems to me that pre-detonation would be the ABSENCE of Knock Reduction. Am I wrong? :?
What does a pulley change and fuel pressure have to do with pre-detonation? :?
Finally, why is the original poster trying to find all kinds of engine parts to sustain the onslaught of pre-detonation, rather than just eliminating the source of pre-detonation in the first place? :?

Smaller pulleys produce more boost pressure and heat. Heat causes detonation/knock. Colder plugs, porting, headers, etc can all help reduce it after the pulley change. Fuel pressure is two-fold. You need to keep up with the fuel demands under full throttle, because a lean condition can cause BOOM in forced induction. In addition, the fuel can have a cooling effect in the cylinder. This is why we run full rich under WOT conditions by design.

Get a Walbro 255lph fuel pump and an adjustabale FPR. I had to do that very thing, but I have a rather odd setup.
In the case of the Series1, we can stick with the OEM fuel pump (L67), as it actually supports more horsepower in stock form than the S2 L67 fuel pump. However, if your pump is old, you should still replace it (just threw this in here for the S1 guys, as the OEM pump is slightly cheaper than the Walbro).

I have to ask, if the pistons are going to be arrive so soon, did you order .020 over pistons to fit the bore? Also, I personally would take the pistons to the machinst prior to the boring to have them individually fitted to each cylinder. Just my thought.... Maybe this is too late in the game for that.
*edit*Nevermind. I misread and thought you said they'd be in tomorrow afternoon. I'm blind.

Well the pistons will be in on monday and the block won't be started until monday so as soon as the pistons come in they will be delivered to the machinist so that each of them can be matched to a cylinder.
and the motor should be in the car and running by the end of the week!!
