Bernardd, i did thank you for your reply in the other thread. I am going for a more efficiant engine system without going aftermarket. Im learning about mid 90's Maximas, M30's, and Z32 systems and researching all before i get started on the hands on part. I may be picking up a complete M30 system this mid-week, so i am going to go over it and see what i can learn by it being out of a vehicle. Also, i have a buddy that is the manager of parts dept at a local nissan dealer that works their fair share of performance cars, and believe it or not, they are also a large aftermarket supplier for Nismo and many other popular companies. He is going to send me over the complete mechanic wiring diagrams and diagnosis information for the Maxima, m30, and z32, sometime this week. Im also going to go over those thoroughly and learn how they work. Im on a few other leads as well. Ill keep everybody who is interested in my project posted on my research, failures, and success.
