I hear a lot of people talking about the same stuff when it comes to turbo's and 12A's, and everyone says tuning is the key. When I started my project, I had a 1984 N/A 12A. I knew that the project was going to be big, and there would be a lot of fab involved, but it's all done now. My real problem is tuning. I have just picked up a 48mm sidedraft dellorto carb and racing beat intake, which will hopefully replace the clunky old nikki which even with my "amazing" turbo prepping skills, was dramatically sub-par. I just recently acquired a wideband O2 Sensor from AEM to try and get the mixture just right, but was really wondering what could be done about spark. How do I know if my spark is firing at the right time? And what about the vacuum advance on the stock distributor? How is that effected by boost? I apologize if this is a hardcore noob question, but if anyone knows anything about it, or has been down the same path, any information would be very helpful.

 

contact robert at rotaryshack he will know also sell's locked dizzys for boost so there is no advance

 

Robert seems like a good guy, but man is he hard to get a hold of...
