intake with an efi system

Vehicle Information: Year: 1982; Body Type: Coupe;

I recently purchased a hobby 82 SC 3.0 with a Haltech efi system already installed. It has The stock CIS airbox and i was wondering what other options there are and if it is worth changing. If you have any other tips to get the best out of aftermarket efi's that would be great.

Idle speed screw unresponsive

Vehicle Information: Year: 1976; Body Type: Targa;

I had my Porsche in for a cold start problem and in the course of troubleshooting the mechanic discovered that my idle adjustment screw had little effect on the idle speed of my engine. He tried shooting some carburetor cleaner into the screw hole followed by compressed air and got a little bit of adjustment back, but nothing like what it should be. What is the best way to clear this air passage?

98mm Piston & Cylinders

Vehicle Information: Year: 1979; Body Type: Coupe;

ChrisI saw you at the Zone 1 Tech Session last Saturday, it is nice to put a face to the advice. Thanks for all of your help here.There was a question from a gentleman who grenaded his pistons and was asking about an upgrade. The Max Moritz 98s are getting hard to find and a good alternative is to find Carrera 95mm Cylinders (they don't have the ring grove on the top like SCs) and send them to EBS Racing to be bored to 98mm and re-plated and then use JE 98mm pistons. This makes a nice upgrade for a 3.0

Cam crow foot

Vehicle Information: Year: 1981; Body Type: Coupe;

Have started to rebuild my SC and wanted to know if a standard 46mm crowfoot can work for the removal and or adjustment of the cam,valves. The price difference between the porsche tool is significant, and I just wanted to know if anyone has had luck with more standard tools?Thanks in advance!Byron
