OT: 911 Info needed, In search of a good site for 911 information Options

[P.Rocket]

My buddy recently purchased a 1972 Porsche 911T. He is getting me to do a bunch of work on it: check it over for troubles, tune-up, servicing, clean up oil leaks, etc...

Just wondering if there's a quality web site or forum like 914world that can be of help to me. Your assistance is much appreciated.

Thanks, Andrew.

If you're not familiar with MFI (which the '72 T had), be very careful what you do. You need to run an NGK BP7ES, and the valves need to be as precisely set to .004" as you can get them. MFI likes perfect valve adjustment. Make sure the heat riser for the MFI pump is intact, clear, and functional, and that the heater boxes are well sealed against air loss. Set the dwell appropriately for the brand of distributor installed. The Marelli dwell setting is different than that of the Bosch. Whatever you do, if you don't have a portable CO machine or a dyno, DO NOT attempt to adjust the mixture. Doing so will almost invariably result is the car running worse than it did before, and you'll lose any baseline settings you might have had. The factory recommends Berryman's Chemtool aerosol for cleaning the air bleed ports at the base of the throttle bodies. You'll need a long extension for the spray nozzle.

In closing, for now, you should know that there are drivability problems with 2.4 911T MFI engines, and they came that way from the factory. It'll NEVER run as well as the E or S cars. BTW, the class on MFI, back in the day, was a week long, and it was one of the rough ones. The Cap'n
