So this project actually started a while ago. I have been working slowly on my own project while working on customer cars on the side. It was one of those facebook post by some kid on behalf of the original owner who was now 87 years old. This one and only owner pre ordered it in december of 1969 and he recieved it 4/70. The maintenance records and documentation that came along with it are amazing. I have always had a passion for the S30 and this was finally my S1 I have been after. It was painted mercedes off white late in the 80s and thats the way the owner wanted it so that is the way he made it. Originally from California it traveled over to the east coast and sat inside a warehouse since 2003. (good thing too becuase I have worked enough cars over on the east coast to see what the salt does to them.) Anyhow the car was listed on FB for a few months and I had glanced over it a few times. It was a few months after I saw it that I decided to contact the seller. I asked if there was any documentation and low and behold I was presented with stacks of paperwork and service history. The ad did say it had an L28 now and this was why myself and I assume others passed it up. Turns out the original engine blew in 1990 and the owner got it serviced (like he always did) at Nissan. They had no more L24 engines so the installed a brand new NOS L28 Long block. It is all documented on the reciepts and work from the repair facility. At that moment I knew this was the car for me. I immediately worked out the viewing and hurried to pick it up with my trailer. It was better than I had expected and the documents made it that much better. It had to sit for some time after I got it home, but shortly I started work making it better. I will post in chronological order the progression of work through pictures. Enjoy...

So I've brought home my Rebello built 3.0 stroker motor and mounted it on the stand. I'm at the stage of selecting and installing sensors. I'm pretty much going with the GM style sensors sold through DIYAutotune but I've got a couple questions you guys may be able to clear up for me. First, I'm using a E31 head that has been modified with big valves, P&P, and injector notches. The E31 never had a cylinder head sensor so I can't just put a compatible one in its place. I probably should have had Rebello drill and tap for one but that's what I get for planning as I go instead of following a well developed plan. Can you guys think of a solution? What have you done? Or have you done without? Second, I'd like to have altitude compensation as I live at 4500' and regularly travel up to 9000' (I live off Mt. Rose Hwy) and down to sea level. I know at least one friend who used a second MAP sensor to sample for barometric pressure. I've also heard of MAP sensors that are monitoring both. What are your experiences? What have you done successfully?
