The old SPG9 company that was sold to Group 9 Performance developed the AID with Brad's help at KC Saab. A.I.D. was an abbreviation for Advanced Ignition Diaphragm but I call my new ones Adjustable Ignition Diaphragm as I came up with a simple inexpensive way to adjust them to 10 degrees under boost conditions no mater what the initial BTDC timing is set at! Anyway they're a highly modified original unit where we cut the the device open and install a stronger retard side spring to correct the retard curve and re-machine the linkage to the distributor for the proper extra amount of retard needed. Besides a professionally done APC control this is the next biggest bang for the buck as far as a "power limiting piece to the puzzle" on these early 16 valve turbo cars! For what you're looking for a set of 27 1/2 lb per hr injectors would work best. The 30's which are actually 34 lbs per hr at 3.0 bar require more than you need to go through for a mild (fun to drive) modification to get everything working together properly. I still do my A.I.D.'s in my spare time and even have some flow matched fuel injectors on the shelf. Dave at Special Performance Group Turbochargers 805-235-3951
