I converted earlier 911 to a boosted system and found it a very straightforward procedure. Bought later model pedal assembly with actuating rod on eBay for $50.00. Bought aluminum base + booster for another $100.00 as I recall. Bought new master cylinder from Pelican. Utilized .250" aluminum plate @ probably
8" x 12" for bolt-in no flex platform for booster / MC assembly, took my time measuring and put the whole lash up in the car. It was very straightforward, worked very well and was by no means difficult. The end result was not something a Porsche purist would endorse, naturally, but, then again the car also had a "Not-A-Porsche engine in it.
