do some research...you're going to get flamed for this post.
the stock fuel system runs out at about 18 psi, which is also the max the OEM MAP sensor can read. Get a wideband in the car to keep an eye on the AFR before you start messing with the boost.
DO NOT just throw a 3 BAR MAP sensor on the car. The S1 PCM is not calibrated to read on a 3 BAR scale so it will cause all sorts of problems.
I have no experience with the PTP spring, but the AGP WGA should be more than capable w/o it.
Just my 2 cents.
