I recently procured a 2006 Mercury Grand Marquis with the 4.6L and am in the process of compiling parts to supercharge it. I've already got the Vortech head unit and bracketry as well as the discharge tubing and a front mount intercooler and BOV. I plan on running a 340 lph pump in the tank but I don't feel like paying over $500 for the injectors Vortech includes with their kits. Any suggestions? Probably need between 36-50 lb. units. Plan on keeping boost below 10psi. The rest of the engine is bone stock. I'm a pushrod guy and new to mod motors. Thanks.
