First off: You can just put larger injectors in and a fuel pump and expect that to give enough fuel and the right amount and under boost conditions. You can keep your injectors you have now, put in a 5th and maybe 6th injector activated by pressure switches to come on and certain PSI settings(you can adjust the switches to activate whenever). Also a Cartech Adjustable FMU is a very good idea, you can adjust when you increase fuel pressure, by how much and the onset of fuel pressure so there is no lean spots.

Second: Another thing needed for safe boosting is timing retard, so a MSD Boost Timing master is a good candidate. The best is a J&S Safeguard system though, it has the function of retarding timing more as boost increases(Just like the MSD BTM) But also will retard more if it starts knocking! Its around $500 though! And the MSD BTM is only $165.

The FMU, Boost Timing Master AND Extra Injectors Are ALL activated based on boost, so when your not in boost it will be the complete stock setting. This is the setup i am using, but i am not putting in lower compression pistons, i plan on running no more than 7PSI, probably just 5PSI to be safe. If you do lower the compression though, i would say this setup would probably let you push 15PSI with an intercooler pretty well, as long as you set it up right and make sure you do not lean out at all and retard the timing somewhat. Gauges are definetely a must for doing this. Have Fun doing it, let us all know how it goes!!!!!!

Doesn't the DME automatically retard the timing??? Isn't that why it's a breeze to install nos???? I would never nos a porsche but I hear the dme takes care of all the funny stuff.
