Go with the E-Code FMIC on Audizine there is a group buy in progress for $795 + shipping which is a great deal. If you want to stick with APR products go with the APR intercooler but it is more expensive and has a few fitment issues depending on the front bumper. Since you already have a diverter valve and are using all APR products I would buy the FMIC now then save almost 6,000 for APR Stage III+. You might also want to think about upgrading to a Southbend Clutch.

 

How about the "racing" N75?
